EFFECT: lowered costs, ensured ecological safety, increased reliability, shorter times needed to launch areas into operation, extended peat extraction season and transition to year-round production.
The invention relates to the mining industry and can be used in the turf industry for peat extraction on undrained and natural peat deposits.
A device for peat extraction peat deposits of the upper type, comprising a horizontal frame mounted on the tractor, on which is mounted a helical screw with the housing and the actuator (SU 1293352, 16.05.1985, IPC IS 49/00).
The device has the following disadvantages - low productivity and not allows to extract peat from a separate genetic layers of deposits with high pistolu. In addition, the use of screw augers significantly limits the width of the peat layer and determines the repeated passage of the driving device on deposits, which affects productivity, environmental safety and reduces the quality of the extracted peat due to the capture and extraction of woody debris in the form of roots, stumps and trunks of decayed trees. This causes frequent breakage of the screw auger and a sharp reduction in output per machine during peat extraction. The operation of the known device determines Stelco and natural drying of peat in the fields of production immediately after the passage of the machine, which causes the necessity of processing the upper rock layer deposits and conducting costly operational Ouse the Oia, which after production of industrial peat layer leads to unmanaged perennial peat fires.
A device comprising a horizontal frame mounted on the tractor, on which is fixed a screw auger with a casing and a vertical chain bar, through which the drive is connected with two horizontal chain bars located in the lower part can be rotated in the horizontal plane. Vertical chain bar cuts through the crack in the reservoir. On the telescopic tube by the feed screw is on the surface of the peat. Peat deposits from selected two horizontally spaced chain bars (SU 977786, 30.11.82, IPC IS 49/00).
The disadvantage of this device is a high energy process excavation of peat deposits, poor performance, high environmental hazard for the environment and low reliability of seasonal production and supply of peat products.
It is also known a device for the extraction of minerals, particularly peat, including hydro and tortas mounted on the boom, through which is pumped peat pulp, which is then transported by pipeline to a special field drying (Weller M.A. Technology gidrotorf. M.-L.: Gosenergoizdat, 1948, p.10-80).
Device for the extraction of peat hydraulic way before the hat is a mobile crane with a long boom, which temporarily laid narrow-gauge railway tracks to the edge of the quarry. The bat goes down arrows on the cable special torfason connected with a hose. Through torfason pumped peat pulp, which is then fed into a connected with him pipeline system, consisting of a metal pipe of large diameter. Turn arrows in a specific sector career, pumped peat pulp, forming a pit dimensions 125×45 PM
The disadvantage of this device is the low reliability, frequent overturning of the crane, slipping it into the quarry, long-term temporary relining ways, break Tortosa etc. in Addition, tortas often self delves into the underlying stratum of mineral soil, causing it damage and dramatically reduces the quality of raw materials - peat - due to the mineralization of peat pulp (increase the ash content of the peat).
A device that includes injection and polypopylene well connected respectively with the pressure and suction pumps, jetting and slurry pipeline. Injection wells consist of truefinish devices in the form of perforated tubes connected by a flexible conduit for supplying water under pressure. Pipes connected to the cylinders to move the unit, the distributors is Alenia water in the system and winches to move the design of the roadway. The rise of destroyed rock in the form of pulp is carried out using air lift, hydraulic Elevator or hidroelektra-arifovic devices (SU 1435777, IPC IS 25/60, B. I. 1988, 41, p.123, SU 1645498, IPC IS 25/60, B. I. 1991, 16, p.87).
The disadvantages of the device for hydraulic borehole mining of coal should be considered is the complexity of design solutions, the steady state for a long period of work and, as a consequence, considerable expenses for moving to a new place. The division into separate units of production wells and polipovidnye well - availability of special StreamReader pipes and systems, winches and cylinders reduces the reliability and manageability of complex increases the likelihood of breakdowns and reduces its performance.
Closest to the proposed device is a technical solution, including mounted on the platform lift with a winch for lifting and penetration of the working body in the form of coaxially arranged outer and inner pipes, the latter of which the lower part is connected with germanicarum, pipeline, drilling rig containing diesel installation and discharge the high-pressure pump (Ahrens WE Borehole mining. M., ed. "Nedra", 1986, p.93-95, 234-237).
The disadvantage of this device is the inability of its application for production techpolicy fossil, as peat peat deposits, large mass, and therefore, metal and energy intensity, the stationarity of the rig, in addition, it is not possible to ensure environmental safety during operation.
The basis of the present invention is the task of reducing the cost of peat extraction, ensuring environmental safety, increased reliability, reduction of the input space into operation, the lengthening of the season peat extraction and the transition to year-round production, reduce energy and metal consumption and increase output per worker, the complete elimination of fire hazard during peat extraction and developed technological areas, improving the quality of extracted raw materials and the complete elimination of the dependence of the extraction of peat from the weather.
This object is achieved in that complex for the extraction of minerals, particularly peat, including mounted on the platform lift with a winch for lifting and penetration of the working body in the form of coaxially arranged outer and inner pipes, the latter of which the lower part is connected with the giant, pipeline, drilling rig containing diesel installation, discharge high pressure pump according to the invention equipped with a water pump with hoses-pipes, vacuu the NYM pump, connected to the pipeline, and the platform is made in the form of a pontoon and are connected by a rigid coupling with the towing vehicle-ATV when it was installed at the platform of interconnected discharge high pressure pump diesel engine plant and a vacuum pump and placed additional pipes for drilling and pipeline capacity, and the working body provided associated with the outer pipe Tortosa, which is located above the giant, and has around the perimeter of the radial holes with a diameter of not less than 15 mm, the giant made in the form of a conical tip, a perforated over the entire surface, with a hole diameter not exceeding 3 mm, and the outer pipe through a vacuum pump connected to the pipeline.
When the hole diameter less than 15 mm rapid plugging them (roots, small fractions) and a sharp decrease in the performance of Tortosa. The diameter of the holes is not more than 3 mm on the surface of the monitor allows continuous mode of washing and grinding the peat deposits at a distance of 2-3 m, forming a sphere around the giant, with a jet of water of a thickness of 3 mm have not only lose energy, but also provide erosion of the adhered layer on the buried stumps, and roots, which, released from the surrounding peat, gradually settle to the bottom the safety layer. When the hole diameter greater than 3 mm is not Tocotronic erosion and reduction of peat deposits, and moving the peat, roots, large pieces to the sides of the area of erosion. A sharp decline in energy washout 1.5 times the diameter of 4 mm and 2 times the hole diameter 5 mm, etc. reduces the quality of the cleaning process, the quality and quantity of peat pulp. Is "the fountain" the release of water up the well through the space between the outer pipe and peat accumulation.

Complex for the extraction of minerals, particularly peat, includes mounted on the platform 1 lift 2 winch for lifting and penetration of the working body in the form of coaxially located 3 external and 4 internal pipe, the latter of which the lower part is connected with the monitor 5, the pipeline 6, the drilling rig 7 containing diesel installation 8, the pressure pump 9 high pressure, the complex is equipped with water pump 10 with hoses-pipes 11, a vacuum pump 12, the United States is m slurry pipeline 6, and the platform 1 is made in the form of a pontoon and connected by rigid coupling 13 with the truck-the vehicle 14, while on the platform 1 of a set of interconnected pressure pump 9 high pressure diesel engine plant 8 and a vacuum pump 12 and placed additional pipe 15 for drilling wells and building of the pipeline 6 and the working body provided associated with the outer tube 3 Tortosa, which is located above the monitor 5 and has around the perimeter of the radial holes 16 with a diameter of not less than 15 mm, the monitor 5 is made in the form of a conical tip, a perforated over the entire surface, with a diameter of holes not more than 3 mm, and the outer pipe 3 through the vacuum pump 12 is connected to the pipeline 6.
The device operates as follows. Using the winch, mounted at the top of lift 2 rig 7, are combined and successively deepened coaxially located external 3 - for pumping and internal 4 - water injection into the well pipe connected respectively with Tortosa 16 in the lower part of the outer tube 3 and the monitor 5. Water is supplied to the injection pump 9 high-pressure injection in the inner tube 4 and out of thin sporoobrazujushchimi jets through the monitor 5 with the holes 17 of a diameter not exceeding 3 mm in the peat thickness, forming the ri this spherical region of destruction, which immediately filled peat pulp. Peat slurry is continuously pumped through Tortosa 16 and flows through the space between the discharge 4 internal and 3 external pipes through the vacuum pump 12 through pipe in the pipeline 6, and then, transporters by increasing the pipeline 6, enters the modular shop 18 for dewatering in a centrifuge 19, granulating, drying and packaging equipment 20. Further products from peat transport 21 is delivered to the consumer. Holes 17 for the removal of peat pulp at Tortosa 16 in diameter is not less than 15 mm or 5 times more than the monitor 5, and are located radially around the perimeter of Tortosa 16 that provides the required quality peat pulp and timely pumping through torfason 16. To move the pontoon 1 with the equipment he by rigid hitch 13 is connected to the tractor by vehicle type 14 "amphibian", which can overcome impassable sections of any on the water content of the peat Deposit.
Complex for the extraction of minerals, particularly peat, is implemented by means of a hydraulic borehole mining of peat (SGDT), as follows.
On peat Deposit (figure 1) choose the primary site of production of industrial deep peat deposits. At points along the pre-marked is Quain 22, consistently, using vehicle-tractor 14 is placed pontoon platform 1, which has equipment in the form of a drilling rig 7. Then make the drilling of wells under high pressure and erosion of rocks and peat deposits, and erosion of the rock and pumping of the pulp takes place simultaneously in the continuous mode and erosion spend sporoobrazujushchimi jets of water from the upper rock-forming layer (hPS) to the depth of the protective bottom layer (hSS, of not less than 0.5 m from the mineral underlying the peat thickness of the soil. Then the peat slurry is transported by slurry pipeline 6 in modular shop 18 for artificial dehydration and further processing of peat compaction, mixing, granulation, drying and shipment of finished peat products in the warehouse, and in the process of dehydration wrung the water return pipeline 23 in the peat thickness, providing water recycling, closed-loop water system.
At the beginning of the erosion of peat water from a pond, lake serves water pump 10 through the hose-pipe 11. After beginning the process of dehydration and triggered a closed water supply system, the pump 10 with the pipe 11 is turned off. The water supply leads through the pipeline 23 water circulating system. With the help of lift 2 rig 7 drill ve is hni rock-forming layer deposits (about 0.5 m) cone tip jetting 5 with simultaneous supply of water under high pressure into the tapered tip of the giant 5 fine jets through the holes 17 in diameter not more than 3 mm After work tapered tip of the giant 5 in the already blurred the peat thickness bury torfason 16, having a perimeter of the hole 17 with a diameter of not less than 15 mm, through which the continuous operation of the vacuum pump 12 pump peat pulp and raise it to the surface. When reaching into the area of production consistency pulp 5-10% of dry weight using the vacuum pump 12 is directed through the pipeline 6 in modular shop 18 for its artificial dewatering in a centrifuge, and then pressed peat, mixed, granularit, dried ready peat production and transport 21 are transported to the consumer. The abstraction of raw water for submission to the monitor 5 and the beginning of the erosion of peat deposits is performed by the pump 10 with the pipe 11 from the nearest pond, lake, and then when you run the centrifuge 19 water pressed through the pipeline 23 is returned to the reservoir after forcing it through the monitor 5 in the well.
This ensures not only a closed water circulation system water supply, but not broken hydrochemical balance in surface waters at this site. Erosion of peat deposits and pumping of the pulp produced in the mining area simultaneously with the depth of all of the working body in tip-compressor water - jetting 5, and after him, and Tortosa 16 (figure 2). Washing is carried out,starting from the top of rock-forming layer (h PS) deposits to a depth of protective bottom layer (hSS), which is not less than 0.5 m from the mineral soil. Thus, retains the upper rock and the lower protective bottom layers of the peat deposits. The depth of excavation is hVirab.=N3(hPS+ hSS) m When you reach a depth equal to hVirab.=N3- hPS, erosion and stop work authority (monitor 5 and tortas 16) with the help of lift 2 rig 7 is extracted to the surface. Then disconnect and unmounts pipes 3, 4, and pontoon 1 move with the tractor vehicle 14 by a distance equal to the diameter of the silt deposits of wells 22 (DSLE.), and all operations are repeated again. When moving the pontoon 1 disconnect and increasing only flexible part of the pulp line 6 connecting through the vacuum pump borehole 12 of the outer tube 3 with the pipeline 6 (figure 2).
Erosion of peat deposits produced from the upper peat-producing layer to the depth of the protective bottom layer of hSSsporoobrazujushchimi jets of water. This ensures that the active top layer filled with roots growing marsh plants peat formation, maintaining continuity quagmire-covered aquatic environment. Floating vegetation, studies show that the active and the active layer must be a power of at least 0.5 m, to ensure the carrying capacity, maintaining the root system hygrophilous plants peat formation. Protective bottom layer representing a consolidated dense peat mass on the boundary of the peat Deposit - mineral soil is impervious screen, and its preservation does not allow water to filter into the soil, thereby maintaining wetland system. The minimum thickness of the protective bottom layer of 0.5 m ensures the maximum possible volume of peat excavation of deposits, maintaining a reliable membrane of the screen and when pumping prevents peat pulp saline bottom layer. The last factor does not increase salinity and ash content of the finished product based on peat.
Peat pulp, after artificial dehydrated to a moisture content of 55-65%, pressed or granularit, mixing with the modifying components, and then molded ready peat products are dried in a drying aggregates to the desired moisture content of certain types of products (biofuels, sorbents - absorbers, fertilizers etc), Packed and shipped by motor 21 to the consumer (figure 1).
The proposed complex for peat extraction (figure 3) allows to achieve ecological security by maintaining the upper peat prodoor the user layer. There is a rapid return of the peat deposits in eutrophic ecosystem swamp-pond that existed earlier. Completely eliminated the occurrence of peat fires on all stages of production and restore wetland ecosystems, in addition, completely eliminated the discharge of wetland wastewater in open waters, related to the drainage of wetlands for all existing methods of peat extraction, because this system has a closed loop water.
In addition, the complex 3-5 times shortens the input space into operation. It eliminates time-consuming and long-term (up to 5 years) duration of initial and operational drainage, a large marsh complex preparatory work (conversion of stumps, surface profiling process charts, laying drains and bridge crossings, milling, tedding, raking, cleaning and stacking peat). When the complex peat extraction begins immediately, and not after 3-5 years after preparing peat for use, as is the case with all the existing methods of peat extraction. This is very important in today's fast investment project that significantly and positively distinguishes the work of this complex from all previously existing.
The invention significantly improves the reliability is the supplying of peat raw materials and getting ready products because it replaces more than 10 different peat machines and units employed, for example, all the operations for the preparation of deposits for exploitation and production of milled peat as dominant in the present production method. A distinctive feature of the implementation of this complex is the lengthening of the season peat extraction at least 3 times from the actually existing in the peat industry, from 3 to 9 months, and for some countries and climatic zones makes it a year-round, why not have all the existing methods of peat extraction. His work completely eliminates the dependence of the process of peat extraction and production of finished goods from the weather.
Compared with the widely prevalent in Russia, Finland, Canada and the Baltic States and is now considered the dominant complex for the production of milled peat, with separate housekeeping of a series of rolls, we offer complex for the extraction of mineral resources (peat) reduces 8-12 times the energy and capital costs. For example, calculations and practice show that when the volume of peat extraction of 50 thousand tons per season the metal content of 1 tonne of peat using the proposed complex way SGDT less than 25 times, and productivity increases per worker more than 9-15 times. Complex when implementing reduces more the than 70 times (250 ha milling complex and 3.5 hectares proposed) the size of land and mining allotments, at the same 50 thousand tons annual programme of peat extraction). Accordingly, it significantly reduces the rent for the subsoil and land use, and almost completely eliminates the costs of reclamation of large areas remaining after extraction of peat milling method, and also allows you to minimize the damage to the fauna and flora, which is very essential for all known complexes peat extraction. The complex also completely eliminates the occurrence of fires in peat extraction, and after it.
