The invention relates to the field of underground mining of mineral deposits, deposited layers, deposits or veins gentle or steep drop.

The method first provides the extraction of fossil out of the ground without its destruction, and by cutting out large blocks, which gives many of the biggest advantages unattainable in other ways.

Along with the new method of extraction of fossil are brand new

- management by partial roof laying-out space cut blocks fossil with a small coefficient of loss reserves:

- shipping blocks fossil in metal frames, delivery trucks, moving in a channel, corner, or rail guide with offline drives or cargo winches for several shipping lanes on both (ventilation and transport) adjacent to the longwall workings, which are used as transport;

- mount the bottom space of the lava mechanized bottom lining;

- transportation of heavy blocks of fossil without them turn 90 degrees overloaded with delivery trucks on the coupled wheels of the transport platform;

- the location of shipping lanes in the lava and blocks on fossil wheel coupled platforms, to which the PRS allows simultaneous loading blocks fossil with parallel delivery track one twin wheeled platform or on two adjacent, concatenated in a single composition.

- Also offers the following new equipment:

- importadas delivery truck with an opening from the side of the stope Board landline installed the spacer hydraulic jacks and hydroflame, at the same time delivers a lot of heavy blocks of fossil and unloading through the end Board with cargo winches;

- design twin wheeled platform of two single platforms with sixteen wheels, resulting in a large load capacity for transportation on two blocks of fossil on one metal plate without reversal when overloaded with delivery trucks;

- design mechanical wellbore lining, consisting of sections fasteners, having in its composition controlled from a panel in hydropredict and the hydraulic jacks, and vernaci and sections of channel, angle or guide rails with flexible connections and the ability to move after slaughter without disassembly line.

Known hydraulic method of mining deposits of fossil short faces with the use of harvesters and hydro with the use of combine harvesters with jetting nozzles, moving along the stope on the rod scraper conveyor and powered roof supports management of crawl the th complete collapse.

The closest is a way to monitor the development of coal seams using the harvester moves along the rod scraper conveyor along the stope and having in its case hydromultipoles (see RF patent №2167290 C1, E 21 C 26/60, 2001). The Executive body of the harvester has a cutting head equipped with cameras mixed with abrasive flowing in a tube. The cutting head is rigidly fixed on the metal tubes of different lengths, which channels water flow high pressure from gidromanipulyatorov. The location of the cutting head ensures the destruction of the coal massif across the area of excavation. The coal is loaded on becoming the conveyor by the action of lateral forces in the formation of a fan of the water-blast, cutting back slit, and the action of shares of the conveyor. Maintaining the roof in the bottom space is provided by the sections of powered roof supports, after shifting which followed the harvester is a complete collapse of the roof.

This method of development contains irrational processes: destruction of minerals in the zone of excavation, delivery conveyors destroyed the rock for transport development and the movement of sections of powered roof supports in the side of the stope management roof full Abrus the tion. These processes greatly complicate the process of fossil especially when working in difficult mining and geological conditions. The destruction of the bottom array of minerals is very energy-intensive, and results in the release of large quantities of coal dust and explosive gas methane into the atmosphere of the bottom space. Due to the large number melkorazmernaja fossil in the area of the grooves combine with nekovee Executive bodies, occur especially abundant methane, which due to turbulence threads and cluttering the space unmanageable and often beyond the allowable concentrations. The presence of the harvester powerful electric motors with large load currents creates a constant risk of the worst explosions of gas and dust.

Executive bodies excavation machines wear out quickly, require monthly replacement, often during working hours. In the presence of the layer of solids or substitution of fossil hard rock requires the use of blasting, which leads to equipment damage, injuries and delays. Due to the fact that in the area of the excavation above the harvester roof is not fixed in unstable roofs, drivers receive a serious injury collapsing rocks.

The destruction of resources in the horn is the mass during its production irrational and for many reasons it further transportation to the surface, warehousing, loading into wagons and delivery to the consumer. Used for transportation of rock mass belt conveyors is expensive, bulky and delicate equipment. Transported the rock mass due to residual gas everywhere emit gas, which, being on fresh stream, back to cleaning the face, increasing the weight of the gas atmosphere. In the process of transportation of extracted rock mass is highly contaminated rocks from the mining excavation and needs further enrichment, which greatly increases the cost of production. Issued on the surface of the rock mass is very inconvenient for the storage, loading and unloading operations, takes up space, needs for transportation in special cars, in the process of storage or transportation ignites spontaneously or gets frozen, which requires the production of special, expensive, and leads to damage of the cars. For acceptance of these products by consumers, as well as in export shipments on rail border crossings and seaports need to build a very expensive sorting and loading terminals. All this greatly increases the cost incurred by the producer, i.e. the miner.

Shipping scraper conveyors for the lava to transport development repulsed fossil of Malop izvoditeley. Equipment conveyors emergency, injure workers. In violation of the linearity of the face in the plane of the layer or in the vertical plane of the traction chain, or scrapers out of the guides, beating transported mountain mass, can go under the roof, touching canopies lining, can occupy a vertical position, may, being heavily loaded, to turn over to an adjacent track, which serves for the movement of workers than pose a threat to their grave injury.

The movement of sections of powered roof supports behind the harvester also hinders the performance of the stope. Modern combines fast, having a feed speed of up to 6-10 m/min, moving on a smooth straight metal rod conveyor with always-on engine. For movement of shields required movement of workers, cleaning pockets, turning on the discharge, then the movement of the sections. Speed fastening may not exceed 2-3 m/min In weak rocks, soil they pressed into it and drown. For shifting required pedirka soil Buscemi along the length of the lava, which requires a lot of time and is heavy manual labor. When rocks soils that are prone to swelling, breed, puchase, beat the base sections, and their shifting also need pedirka soil that is heavy is th manual labor. In connection with variable capacity reservoir along the length of the excavation pole, there are extensive areas where the provision of adjustement of shields insufficient. In these areas there is often a clamping dry with a large number of sections falling roof. To release expensive sections they have vyrulivate of roof rock that is heavy manual labor, or conduct blasting operations miscellaneous charges that quickly leads to breakage and damage to the equipment.

All of the above suggests that the technology attachment stope, based on the movement of mechanized sections after podvigina slaughter low-tech, hinders performance and has no prospects. Moving shields leads to collapse of the roof. However, it should be noted that the control roof complete collapse of environmentally unfriendly. The complete collapse of the roof leads to the destruction of all the overlying strata, which also may occur minerals. Their destruction and even jobs makes them unsuitable for mining. The displacement of the overlying layers leads to hydraulic communication with the upstream aquifers or watery rocks, and with a little depth and water bodies on the surface. All of this dramatically increases the water supply treatment in the faces and adjacent mountain expressed ODI, Obvodny mine. Pumping to the surface of the acid and alkaline mine waters in large quantities rather exacerbates the environment. In many cases, the application of the collapse of the roof when doing cleaning work is impossible. Finding quicksand or aquifer, as well as protected objects on the surface making it impossible to maintain the treatment works. Loss reserves thus attain very large values.

The task of the invention consists in a significant performance increase stope, a significant reduction in the cost of production at the highest possible quality, a much higher level of security of wastewater treatment works, achieving a high level of ecological production across all factors, the elimination of heavy manual and non-mechanized labor, to minimise the impact on production variability and geological conditions and actions complicating treatment works and geological factors, eliminating the need for additional related mining industries: drainage and lowering of the aquifer, the enrichment of the rock mass, degassing the mined seam and satellites and others, the reduction of metal consumption and energy intensity.

This object is achieved in that in the method of underground mining field is different minerals, including the extraction of minerals by cutting it from the bottom of the array blocks using gidroliznyh cars moving along the stope and with the Executive bodies of the giant type, equipped with cutting heads and chambers of the mixing water with abrasive and United through a metal tube on which they are rigidly fixed, with a power line running from the multipliers, giving ultra high pressure water, and subsequent transport blocks, introduce new steps: the extraction of fossil produce cutting his gidroliznyi and electric machines of the bottom array of rectangular blocks, which are in the process of cutting wear metal frames for easy handling and transportation, loading cut blocks on the delivery truck is done according to pre-open from stope Board, the fixing delivery trucks provide the thrust jacks, stationary associated with the delivery truck, moving the loaded haul trucks is carried out in a cleaning formulation for delivery paths through the channel, corner, or rail guides with traction cargo winches, located in the berm near transport workings or using avtonomnykh drives, the delivery is carried out on adjoining Oistamo slaughter transport and ventilation mining, are overloaded with fossil haul trucks on a wheeled vehicle platforms without reversal blocks of fossil fuels and transport of minerals, the distance between the rail tracks are equal gauge to allow transport blocks on fossil twin wheeled platforms with the movement of the locomotive in the middle of the track, produce management by partial roof laying-out space blocks of fossil fuels and produce bottom mount workspace lava individual basis and metal verhnekame or mechanized bottom hydraulic shoring, section fastening which consist of these props and Varnakov and sections of the wheel guides and hydropredict with control panel on each pair of mounting sections.

The distance between two neighboring blocks fossil, located on one wheel coupled to the platform and adjacent platforms, accept the same and equal to the distance between the rails in longwall workings.

You can cut rectangular blocks in rows, while the depth of the PoWPA is cutting a slit in the soil and the top of formation take twice the thickness of the cut blocks fossil.

The invention is illustrated by drawings, each of which shows the following:

Primary water is fed into the machine 3 from line 7, built along the lava. Energy for operation of the multipliers is the hydraulic energy of the emulsion obtained from the pump station located on the roadway. Emulsion gidroliznaja machine receives the pressure line 5. Old emulsion gidroliznaja machine gives in the case drain line 6.

The delivery truck has three sections (see figa), which are separated from each other big wheels 26. In each section are three units of fossil 24. Therefore, only the cart contains 9 blocks. To the bottom of the truck did not cave in under the weight of the blocks fossil in each section of the truck from the side of the face, there are two additional wheels of small diameter. The diameter of the additional wheels are selected of such size that they do not interfere down the sides of the truck at p is CVU loading units in production.

From goaf all truck wheels 26 have a larger diameter. This provides a reduction of rolling friction during movement of the truck with a very large load. On the truck side goaf stationary set opposite each loaded block by two hydraulic jacks and one hydrocal. The hydraulic jacks are needed for fixing the position of the truck when loading it blocks, and hydrocal necessary for mechanization of loading.

Underground mining of the minerals by way of Kaimana is to cut fossil large rectangular blocks using gidroliznyh and electric cars and delivery cut blocks on delivery trucks to one or more adjacent longwall mines, which are used as transport. Then overload blocks fossil mounted on a wheeled platform. In order not to produce a reversal of the blocks, when the length exceeds the width of the wheeled platforms for transporting blocks of fossil within the mine workings adjacent to the lava can be applied paired wheeled platform, moving in two rail tracks. The distance between the tracks should be equal to the width d is Savoy gauge. Then the motion may be provided by the locomotive moving along the inner or middle track formed by the inner rails of adjacent tracks. On team transport the mine workings is overload blocks fossil on a single wheeled platform, in which the extracted blocks fossil move to trunks. Cut blocks of fossil produced by successive manufacturing processes:

- cutting (figure 1, a view in profile of a gap at the soil layer along the entire length of the lava depth of 2.2 m and a thickness of 0.14 m (e.g., electric machine "Ural-33");

- chasing (top view, see figure 2) transverse slots 4; energy for operation of the machine is the hydraulic energy of the emulsion, which the machine receives from the pressure line 5 and gives it back in the case drain line 6; the working fluid for cutting through the cracks is water (20 l/min), which gidroliznaja machine receives from the water line 7; cutting transverse slots is gidrostatom with the end of the stem cutting head to one side actions; for cutting through the cracks hydroresc is introduced into the bottom slot so that the spray side of the action was directed upwards; when moving hydroretake deep cracks formed vertical transverse cavity; movement hydroretake several times and back into creating the fast smooth vertical slit at full capacity thin layer of the required thickness (not less than 50 mm); when designing seams of medium thickness similar cavity is created from the top down through the crack in the roof of the reservoir, which is a cross slit at full capacity of the reservoir;

- sweep the cracks in the soil layer from the rubble formed by cutting the bottom and transverse cracks; chips from Stripping is loaded into a special frame 8 (see figure 3, a view in profile); after filling the frame with rubble last issued from lava delivery trucks, and mining units;

the valve cages under cut blocks fossil in the bottom 2 (see figure 4, a view in profile); the valve is in a pre-cleaned gap from the source 10 11 in the working position of the frame with the help they are used; the framework necessary to ensure the ability to move blocks of fossil delivery, transportation, cargo handling works without destroying blocks fossil;

- cutting electric machine 12 of the upper slit 13 in the roof strata depth of 2.2 m and a thickness of 0.14 m along the length of the lava (figure 5, a view in profile);

- chasing (see Fig.6 view profile) rear slit 14 of the first politicla; the cutting is made in the mechanised Executive tool 15 having gidratnuju head to one side steps 16; cutting head, mounted on a metal tube with an outer diameter of 10 mm (inner 2 mm) is inserted into the upper slot 140 mm thick at a depth of 1.1 m thus, in order starting from the head water jet was directed vertically downwards; in the process of moving gidratnoi machine by the action of the water jet high pressure is created in the rear vertical slit, separating the cut block of fossil first politicla from the rest of the array in the development of thin layer; in the vein of average power from one stream down from the top of the slit is not enough due to the large capacity of the reservoir, so in this case it is necessary to make cutting the lower part of the rear slit from the bottom up action similar tool from the bottom of the slit to enter the metal frame;

- loading blocks fossil 1st politicla on the delivery truck (Fig.7 view profile); after cutting back slit stope cut unit 17 under the action of its weight (3-15 t depending on removable power layer) sits in a frame 11 having walls on all sides except the rear at a height of half the capacity of the reservoir; from standing in front submersible units delivery truck comes off the Board 18 from the side of the stope and falls on the ground; and simultaneously thrust between the roof and the soil hydraulic jacks 19, stationary mounted on the trolley over the entire length at a rate of two against each loaded block; this locks the position of the trolley when p is the load blocks; itself the loading is carried out by the action of the hoist (for example, hydrocele, electric hosts and others) 20, a stationary mounted on the trolley next to each loaded block with the use of cables 21, the ends of which zastropovana to handles Cherkasov 22;

- cutting back slit 23 (Fig view profile) when cutting blocks 2nd politicla is similar to cutting back slit 1 politicla;

- loading mining blocks 2nd politicla on the delivery truck is similar loading blocks 1 politicla.

Issuance of coal blocks of lava is both adjacent to the longwall mining, since the vent output is also used as transport within the jet odswiezenia when flow diagram ventilation (when developing vysokogazonosnyh layers).

Shipping blocks on fossil transport formulation is hauling trucks (see figa and b, front view) on several parallel lines, channel, angle or guide rails. Movement sufficient trucks is provided by mine trucks and safety winches. On figa shows the appearance of the delivery truck from the side of the stope. Delivery truck consists of sections (figa three sections), where the blocks fossil. Figure 9 in each section once amauta three units of fossil 24. Between the sections has an open area of 25 whose length corresponds to the length of blocks fossil, cut in the bottom of the array and move in a goaf for partial bookmarks. The location of all blocks on fossil delivery cart according to their location in the bottom array. This provides the possibility of their simultaneous loading in the development of thin layers or alternating loading heavy blocks without shifting truck when designing seams of medium thickness. To reduce rolling friction when moving hauling loaded trucks are maximum diameters of the wheels 26, which are arranged from the side of the stope in front of vacant parcels (not to discourage disclosure Board from the side of the stope) and evenly from the side of the goaf. In order to prevent excessive deflection of the bottom of the truck under heavy weight blocks fossil (when the reservoir average power) cart with hand stope provided by the use of wheels of small diameter 27. On figb shows the position of the spacer legs 19 for fixing the position of the truck during loading blocks, and hydrocele 20, ensuring the process of shifting blocks when loading them into the cart.

The delivery truck was the means of delivery not only cut out from bottom of array blocks to fossil transport workings, but free metal frames transport from mines to the loading of the cut blocks. The truck has a body with an opening from the side of the stope Board (as shown in Fig.7) and opening in the direction of transport of mines end doors at both ends of the truck (see figure 10), the basis for fixing the position of the trolley when it is loaded blocks fossil and hydrocele, through which directly is loading. The hydraulic jacks and hydrocele stationary on delivery trucks from out space. The open side of the truck is divided into separate sections (to reduce weight when they are opening and closing), because it is made of durable metal plate, withstand the weight of a unit of fossil moving on it when loading the truck. The length of each separately opening section side of the truck is equal to the length of the cut blocks.

The total length of all blocks that are placed solidly on the delivery truck, equal to the distance in the developed space between lay it blocks. The length of the free area on the truck is equal to the diameter of the main wheels of the truck and is equal to the length of lava lay in stope blocks fossil.

Hauling cargo winch 28, providing predvideni the delivery trucks on lava are the berms associated with the transport workings (see figure 10, front view). They are also used for handling blocks of fossil-24 delivery trucks 18 coupled to the wheeled platform 29. For this purpose, the delivery truck is opened the end door 30 and falls on the edge of the wheeled platform. The end of the rope cargo winch 28 stroumsa to the end of the front frame unit. Turning the winch due to the movement of the cable is provided a moving block of fossil mounted on a wheeled platform. After moving the composition wheeled platforms on the path length, sufficient to before the delivery truck came the next free spot on the platform for the next block of fossil, the process is repeated and so on until the complete unloading of delivery trucks. Next is loaded on the delivery truck frames under the mining blocks fossil. Loading is done by pulling up with a shunting winch free frames section goaf lava adjacent to the width of the frame to transport development, where they are pre-loaded with empty composition, to make space for loading the mining blocks. In order to free up space for incoming frames and their spread before loading, hauling the cart should pen is to move into the lava on the length of the frame. The delay of the frames inside the delivery truck can be made using shunting winch and cable, which stroumsa to face the opposite side of the frame. This winch is located in the middle of the lava on the line of the delivery track is safety when driving a loaded delivery truck and is used as a traction during the reverse course truck to the place of unloading of empty frames and forth to the place of loading frames with blocks fossil.

Mount the bottom space of the lava can be individual basis and metal verhnekame, or mechanized bottom lining (please see figa and b, type in the profile section of the fastening which consist of the same legs 32, Veshnyakov 33, wheel guides 34 (channel, corner, or rail) and hydropredict 35. On figa and b sections of the fastening consists of three serial jacks and six serial metal Veshnyakov, one they are used, two sun loungers and two sections of the channel guides.

The hydraulic jacks share the bottom space on four business departments. The first part of the account of stope the Department is designed to accommodate and movement Ironman and gidroliznyh machines and has an appropriate width.

The first part is attached one hydros what oikoi and one cantilever hinged roof bar. It also has frames for storing in them Shtyrov of the slit of the slit, the frames under the mining blocks and frames to move the blocks fossil in a goaf.

The second and third branches are used for hauling equipment. Dashed lines in the 2nd and 3rd branches figa and b shows the contours of moving them on channel guides loaded mining blocks haul trucks. Each of these offices provides one feeder track. Mount in each of these offices is provided by hydraulic jacks mounted on the edges of the branches, and two pivotally United verhnekame. On the ground of the second branch are the guides section and one ground (lounger), which relies on the legs. On the soil of the third separation section are guides and they are used, on which rests on top of the legs.

In the 2nd division side, adjacent to Oistamo slaughter, is also used as a reserve area for the location of gidroliznyh machines and cages to free the passage for electric machines running on a new cycle. Support for 1-St and 2-nd props are sunbeds 36, which is connected with the sections of the guides 34. Support for 3rd the hydraulic jacks is they are used 35 providing displaced the e whole section mounting. All sections of the fastening pairs are connected via a common two sections of the wheel guides. Between the sections of the guides are connected in a hinged connection that enables them to move without uncoupling of the sections of the guides following excavation blocks in each polycycle from the middle of the lava to both sides.

The fourth branch is intended only for moving workers, and has a completely free flow section. The fourth branch fixed one hydrostone console under the exposed roof bar. Just the mounting kit lava in cross section has three hydraulic jacks, six metal hinges United Veshnyakov, two metal base (lounger), they are used and two sections of the guides.

Each section guides interlocked with the two sets of supports and forms together with them and guides section of the second delivery paths in the General section of the mechanized bottom lining. Thus, in one section of powered roof supports are 6 legs, 12 metal hinged roof bar, 4 bases (metal lounger) and 2 they are used. The length of the bottom section of powered roof supports is determined by the length of the section of the guide. Section guides have a hinged connection that enables their movement after the and clearing face without disassembly.

Moving mechanized bottom lining can be seen when comparing its images on figa and figb. The first image corresponds to the beginning of the cycle, and the second the end.

Management roof is a partial tab in stope cut in the bottom hole array blocks fossil small (substandard) section that provides a slight loss of fossil (up 5%). Blocks in the developed space laid out the strips with the distance between them, providing uniform (without collapse) landing with a smooth deflection preventing stress concentration rocks, insignificant load on bottom lining even with very long faces, as well as the stability of the outcrops in the immediate roof in the loading zone of the mining blocks on the delivery truck. Move the blocks fossil in a goaf is also in the frame, which after shifting retrieved from under the blocks and remains in place for shifting the blocks in the following cycles and half-cycles. The shifting is performed, for example, using portable hydrocele, which are fixed to the previously peredvinuli blocks caught the descending roof. To move through the sections of the guides on them is placed in a special decks. The shifting blocks etc is performed between the sections of the mount without removing the legs. The size of the block under the roof in this regard, may not exceed the distance between the mounting sections along the length of the lava. From the loading condition of the mining blocks on the delivery truck to its full load without shifting block length must equal the length of the free section 25 (Figure 9, a and b) between the loaded blocks fossil sections haul truck.

Transportation resources is to increase the overall performance on both adjacent to Oistamo slaughter mining. With the increased length of the mining blocks (in order to increase performance stope length can be increased to 2.8 m) composition, formed for the transportation of mining blocks should consist of paired wheeled platforms (see figure 10, a front view and Fig, top view). The paired platforms are constructed from a single platform, each on its own rail track, by blocking metal beams-ties and laid on top of the stove (figure 10), which is the working surface for placement on her blocks fossil (see the contours of the block 24 figure 10).

Since each track laid two rail track width 900 mm, the distance between them is also taken 900 mm So there is another track - inner (middle). This inner track lane is moving locomotive. Behind him moved in two tracks as a single unit semi-detached two (one for each track) wheeled platform. Therefore, the total width of the interlocked wheeled platform is 3150 mm, which is sufficient to accommodate the width of the platform issued from lava blocks fossil 24 length of 2.8 m Length 2.8 m taken in connection with the fact that this value is limited by the length of the mining blocks in terms of their subsequent transport on a single wheeled platforms, where they are loaded with dual platforms for modular transport and mines for further transportation of production to the trunk. Thanks to the availability of transport precinct workings under the loading points lava twin wheeled platforms, there is no need of a reversal of heavy mining blocks that otherwise would have sharply limited the performance of loading points.

When unloading mining blocks mounted on a wheeled platform along one delivery line may not be possible to unload the delivery truck with a parallel feeder lines. To avoid this, the distance between the tramlines in the bottom space of the lava should be the same as the distance between the sites for the location of blocks of fossil on one platform (where stacked two blocks fossil)is between adjacent areas in close spaced along the length of the working wheeled platforms.

For the free movement of carts to mining blocks did not touch metal vernaci bottom mounting) requires that when cutting blocks total thickness cracks in the soil and the roof of the reservoir exceeded the stock in subsidence of the roof of the sum of the thickness of Varnakov and the distance from the soil lava to the work surface occupancy mining blocks on delivery trucks.

Development of mineral resources by way of Kaimana also leads to a significant increase in performance. Electric machine cut slits in the roof and soil layers to a depth of 2.2 m with a speed of 2.8 m/min Speed-cutting gidroliznyi machines and rear transverse cracks can only be more, because numerous experimental tests proved that waterjet cutting thin jets of water high pressure (up to 3000 ATM) is much more efficient than mechanical cutting metal teeth, in particular, for some types of minerals. Based on these values, the daily performance of the stope, developing, in particular, a thin coal seam with a capacity of 1.2 m is 16 thousand tons of coal per day. When developing sloping seam of coal with the angle of incidence of up to 9 degrees and a capacity of 3.0 m performance in day by cutting coal blocks is 40 thisaction per day. When such equipment resources cut blocks of fossil actual performance stope is determined by the capabilities of high-speed loading of the mining blocks in delivery trucks, their capacity, the number of manufactured flights per day, capacity overload mining blocks mounted on a wheeled platform, the receiving ability of these platforms. Technical solutions of the present invention provide the best possible performance in all these processes. Thus, the capacity haul truck provides simultaneous transportation of nine production units, which in the seams of 1.2 m gives the weight of a payload in the truck 36 tons, with capacity 3.0 m - payload in the truck 100 t Delivery truck - samopogruzki, as are all necessary for high-speed loading of the mining blocks. In the development of thin layers of loading all the blocks are at the same time, when the reservoir capacity 3 m - consistently for a minimum time. All the processes of loading and unloading units are mechanized. To improve performance, delivery, issuance of mining blocks are on different trucks on both adjacent to the longwall workings, which are both used as transport for several Parallels the existing shipping lanes, working independently from others who ha Unloading mining blocks with different tracks are also mutually independent. All of this greatly increases the overall performance of the delivery vehicles. The use of paired wheeled platforms practically solves the problem of high-speed unloading without reversal of oversized and heavy mining blocks. However, the technology unloading blocks with trucks built so that unloading can be carried out on the soil of lava in the area of its coupling with transport production delays filing wheeled the empty platforms. Thus, the duration of the flight hauling trucks also dependent upon nothing and is reduced to a minimum. The fact of the independence of the performance of the delivery process from external factors is unique in the organization of transportation process and makes this technology of delivery is very attractive.

A major advantage of the invention is a departure from the control roof complete collapse. This method of control roof unfair in its essence, it is not possible to have long lava, as it gives a large load of rocks in the roof lining. When short lengths of love, it is impossible to achieve great loads on lava, a few for this you must have sorbitrate lining. The switch to control the roof partial C the masonry coal blocks with little loss reserves can completely abandon the very heavy, massive and extremely expensive treatment mechanized roof supports. Instead, the lava used light bottom mechanized lining of the serial jacks and metal Varnakov and hydropredict. Mount becomes fast, easy and very cheap.

Invaluable an important advantage of the method of development of large blocks is the removal of restrictions on daily performance stope on the gas factor. When developing fossil large blocks of missing stream thump of hands fossil. So when developing coal bed is absent most dangerous and powerful uneven source of release - flow of methane from the broken coal. In connection with neopushennye roof is also missing another very gotobilling source gas release from satellites and goaf. In this regard, gazoobilnosti at the treatment works is reduced to three or four times. Eliminating the necessity of doing in the mines even sverhkategorijnyh gas degassing factor works both in developed reservoirs and satellites.

Quantitative calculations demonstrate the technical possibilities of this method of development sloping coal seams to have a stable, independent of the complicating action when the conventional methods of mining and geological factors,the average production level for thin shallow layers (at the moment) - 16 thousand tons/day, for the seams of medium thickness - up to 40 thousand tons/day, which is approximately twenty times the level of the existing pressures on treatment faces. This is because this method is new and gives rise to much more advanced technology of wastewater treatment works, which (probably) will develop the technology of underground mining in the next thirty to forty years

- non-use in Stopes complex, unwieldy and very expensive treatment mechanized complexes, the transition to the use of in love easy, but inexpensive mechanized bottom supports, electric and gidroliznyh cars, delivery trucks, channel guides, mine cargo winches;

- optional use on the underground transport of minerals scraper and belt conveyors, motorized and mountain bunkers, the transition to a single mode of transport along the shaft of the wheel, as well as a significant reduction in energy consumption due to non-use of actuators treatment harvester scraper and belt conveyors, the energy consumption for cutting slits when cutting blocks many times less than the complete destruction of the array harvesters;

- significant reduction of the cost of development works in connection with the small value of the specific volume of the performance of the preparatory mining thin seams of 3.8 m/1000 t stocks and 1.0 m/1000 tonnes of reserves at the seams of medium thickness (when existing technology 20 m/1000 m and 6 m/1000 t stocks, respectively); this is due to the increase in the length of the stope on thin layers 340 m and on the seams of medium thickness (3.0 m) - 630 m;

- high productivity: in the absence of heavy manual and non-mechanized labor, widely used in conventional mechanized excavation in connection with the impracticality of complex mechanization to work in difficult mining and geological conditions, characteristic of the mines of the Russian Federation; productivity when developing large blocks on thin layers is underground - 20 t/out, Oistamo slaughter - 40 t/out, on the seams of medium thickness: underground - 52 t/o, Oistamo slaughter - 100 t/out;

- there is no need for auxiliary processes: drying, degassing, enrichment of large blocks of coal.

- when developing by way of Kaimana anthracite (for example, in Rostov coal basin), the consumption of anthracite depends on its grade, which is determined by the size of the pieces of anthracite; screw harvesters and pour on belt conveyors badly crushed anthracite, which leads to loss of quality; mining anthracite large blocks allows the surface Proreznaya machines to cut anthracite briquettes and modern packaging to supply the population and abroad anthracite products, raising ku is Turu the heating process, to ensure high competitiveness and good marketing.

Development of fossil large blocks allows you to raise the security level of the sewage treatment works at a higher level. This is due to nerazresene array fossil in the scattering, which leads to high dust and gas oralocaleinfo space, and if the harvesters electrical high-power creates a permanent threat of the most severe dust explosions;

- when developing coal seam significant relief gas regime at the treatment works in connection with the liquidation of catostomini from the broken coal and goaf; large area uncluttered bore bottom space (up to 8 m²on thin layers and up to 20 m²on the seams of medium thickness), allowing the air in sufficient quantities, its free movement and lack of occurrence of stagnant zones, zagazowani and excessive temperature rise of the air in a mining face;

- creating a safe, no cluttered passage for people (4th branch, see figa and b)having a width of 1.1 m, convenient for quick movement;

- rejection control roof complete collapse and transition to management partial roof tab of the block and fossil with a small distance between lay strips provides gradual smooth deflection of the roof, no stress concentration in rocks, minor load on bottom lining, no stabbing, cracks, wood thrown, stability outcrops;

- the possibility of non-use in a mining face scraper conveyors, conveyor chain having great tension, when zastarovje guides or mould out of the guides and the curvature of the line stope can, turning, move to the line of movement of workers, it is hard to hurting;

- non-use of combine harvesters, traumatic workers teeth augers; harvesters not attached naked roof between the screws and in the bending area of the conveyor, that stops combine leads to the formation of wood thrown, the necessity of finding work under the exposed roof for cleaning rocks, preventing movement of the harvester supports, and their injury collapsing rock.

- through the development of large blocks do not sliianie coal in wagons and receiving hoppers, the combustion of coal during transportation and storage, warehousing and handling.

Application development of coal seams in large blocks without destroying the array fossil, allows you to create a truly eco-friendly production at wastewater treatment works, as there is no ingress of coal dust in the atmosphere p is sabinoso space; created Ironman and gidroliznyi machines dross is located in a deep narrow crevices, where he set the preferences of mine paliatsos filled in a closed metal frames;

on average 3-4 times reduces the release of methane extracted from coal in the mine atmosphere in connection with the liquidation of the most intense sources of methanofullerene: from the broken coal and goaf;

in connection with neopushennye roof in the mined-out space do not result in loss of minerals that are deposited on the developed layer and falling within the zone of destruction;

in connection with the smooth deflection and uniform subsidence of the roof as crushing leave in the developed space blocks fossil there is no need to leave vast areas of fields fossil under the surface reservoirs, primaryitem, residential buildings, Railways than eliminated significant amounts of loss reserves in the security pillars;

also due to lack of hydraulic connection of the sewage treatment works located above rocks, waterlogged, or aquifers, which leads to a sharp reduction in water production in mining and a corresponding decrease in the issuance of a surface mine water;

the absence of p the surface placer mining areas of its warehousing, at the site of loading into wagons in connection with the issuance of mining on the surface of large blocks, the lack of coal dust on the clothes of the miners and their faces makes it possible to raise the culture of production at coal mines, to clear the area of the mine yard and airy atmosphere from coal dust.

The non-use of heavy mechanized treatment equipment allows to pass the love of heavy non-mechanized labor for installation and especially the dismantling of mechanized systems. There is no need to manually cut from rocks trapped by the roof of vernaci or drowned in the rocks of soil heavy Foundation supports, lead them disassembly, manually disassemble rusted bolt connections, etc. used in Stopes bottom light mechanized lining eliminates these phenomena.

The same thing happens during operation, when due to lack of adjustement of shields in some areas due to the fluid capacity of the reservoir is the clamping of the shields descending roof, or in connection with weak soil is the indentation in the base of the lining and the soil and requires manual wirabuana rocks and soil of the roof along the entire length of lava.
