 Erection method of protective cushion above developed vertical ore bodies under permafrost zone conditions / 2503814
At the bottom of the developed open pit there created is a freezing circuit by driving of zigzag-shaped trenches and laying of pipes in them; after that, ice rock backfill is erected by freezing-out overburden; a waterproof screen is laid and filled with a clay loam layer. Then, an upper freezing circuit is made of pipes and a heat-insulating layer of local loose materials, a waterproof screen and a clay loam layer is erected on it and covered with overburden. As a protective cushion is being created, cold air is delivered via lower freezing circuit, and cooled air is supplied via upper freezing circuit during warm season.
 Method for open mining of mineral deposits by application of mill holes and cyclical and continuous method (ccm) / 2495244
Method includes identification of stages and substages and arrangement of a deep pit at differentiated angles of a slope, a board in accordance with reducing natural and anthropogenic damage of massif rocks with depth to arrangement of vertical ledges and sections of the board in deep zones. The stripping thickness of rocks is separated in the transverse cut in hanging and lying sides of the deposit for inclined and steeply inclined layers with capacity corresponding to substages and stages of the developed deposit. When the pit is operated at the first stage, the ore body is stripped with mill holes so that the ore transportation arm makes the minimum value. The milling link is installed near the mouth of mill holes. And also mill holes and inclined mines are tunnelled with a conveyor for ore delivery to a factory or a reloading point. Mill holes are tunnelled by drilling and required inclination of a mill hole shaft with (for instance, 65-70°). The optimal weighted average ore (rock) piece is provided with the help of a drilling device and thorough cutting of the mill hole with required parameters. To eliminate critical compaction of ore mass, as pieces collide with the "cushion", adjacency of the hopper to the mill hole is arranged at the angle for collection of bulk material in the hopper in the loose condition. Freezing of the ore mass or formation of anthropogenic mud flow due to water saturation is excluded with its continuous transportation and discharge from a manhole device to a feeder and a conveyor or directly into rail cars during liquidation of random vault formation from large ore (rock) pieces. Besides, the feeder and the conveyor are arranged in the upper part of the mine, and cars - in the lower part, and operations are continued as mining works and mill hole cutting gets deeper with movement of the drilling complexes to lower horizons with the minimum arm of ore (rock) haulage. When operating in other zones (along ore trend) or its completion, for these purposes other mill holes are arranged so that the achieved arm of ore haulage compensated costs for their arrangement.

FIELD: mining.
SUBSTANCE: method includes performance of stripping and clearing mining works in opencast manner. At the same time working sites are arranged at the ledges with release of beds. As the cut reaches the border of the mining allotment along the depth, they arrange a cross-cut from the bottom of the stripping mine cut, and the cross-cut is made at a small angle upwards for organisation of self-flow hydraulic transport of coal, to open all beds of coal measures lying in the border zone. Along the beds indicated for further mining, from the cross cut to both sides at the small angle upwards they arrange drifts. On the soil of the cross cut and drifts they lay chutes for organisation of self-flow transport of pulp. From the working site of the ledge along with bed slope they drill a well to a drift, in which a hydraulic monitor and a pipe column are installed. Damage of the coal around the well is carried out by a hydraulic monitor jet in the reverse order. Broken coal is transported along chutes of the cross cut to the bottom of the cut, where it is accumulated in both and more reservoirs without mixing. For more efficient development of the field it is possible to mine simultaneously two and more beds with different compositions of the coal substance.
EFFECT: increased efficiency of complex development of coal field.

The alleged invention relates to mining, in particular to the integrated development of coal deposits, including the seams of different capacity with valuable content of chemical elements, and open-pit and underground development of steep and steeply inclined seams on the ledge of the Board of coal mine by dredging.
There is a method of conducting surface mining in which the development of the breed, its transportation and laying the blade is made by using the energy of moving water [1]. The disadvantage of this method is that it involves dredging the development of overburden and does not affect the development of the coal seam, i.e. the use of means of dredging only in the preparation of a coal seam to the notch.
The known method open-pit mining of coal, including maintenance Stripping and cleaning of mining operations, the subsequent conduct of revealing develop from the bottom section, the installation of the giant with the rod pipe, the destruction of the coal around a working jet stream in reverse order and pumping the slurry to the surface [2]. The disadvantages of the prototype are:
- the collapse of the roof rocks at the far boundaries of production leads to the dilution of the pulp, resulting allowed increased loss of coal in the bowels;
- increased costs of energy and materials is impressive for pumping slurry to the level of the bottom section, since you need two pipes for water supply and pumping of the pulp;
- increased material and labor costs for installation and disassembly of the fastening develop due to the need for a large number of such openings;
- the lack of a complex field development, as thin and very thin coal seams, even with a relatively high content of valuable chemical elements, cannot be practiced in a manner so as conducting revealing the workings on such layers requires high labor costs, materials and time
These drawbacks reduce the efficiency of the integrated development of the coal field.
The purpose of the invention is improving the efficiency of integrated development of coal deposits due to involvement in the mining of coal seams with content of valuable industrial chemical elements that lie in the selection area of the incision, by open-pit and underground design them hydraulically.
This objective is achieved in that in the method of integrated development of coal deposits, including maintenance Stripping and cleaning of mining operations in the open way, the subsequent conduct of revealing develop from the bottom section, the installation of the giant with the rod pipe, the destruction of the coal around a working giant jet back in the order and pumping the slurry to the surface, in the conduct of surface mining on the ledges form a working platform with the release of the layers constituting the inventory selection area of the incision, as the opening production use verslag held at a slight angle up for the organization of gravity of the hydraulic transport of coal and which open all the seams mining, lying in the selection area, the layers are intended to further the development, from Kerslake in both directions at a small angle hold up the roadway, on the grounds of corsega and drifts stack chute, with the working surface of the ledge on the dip drill hole to drift, the giant and becoming pipes mounted in the well, the coal getrootpane from the well at the same time are two or more hydro in different layers with different compositions of the coal substance, the broken coal is transported along the gutters of corsega to the bottom section, where they accumulate it in two or more containers without mixing.
The invention is illustrated by diagrams. 1 shows a diagram of the opening selection of the stocks section; figure 2 is a view in plan; figure 3 - the node B, marked in figure 1; figure 4, 5, 6, 7, 8 - cross section of corsega with different number and order of installation of the gutters.
The method is implemented as follows. When doing Stripping and cleaning of mining within the mining allotment cut form working the e site on the ledges so to the strata in the coal substance which identified industrial content valuable chemical elements and lying in the selection area of the section, would go to the working area. Upon reaching the cut boundaries of the mining allotment depth development approximately in its middle part with the bottom cut spending verslag 1 at a slight angle upwards (for the organization of gravity hydraulic), crossing all layers developed suites. The layers constituting the selection inventory section and planned for further development because of the industrial content of valuable chemical elements-admixtures, conduct drifts 2, 3, 4, 5 in different directions from Kerslake at a slight angle up for the organization of gravity hydrotransport slurry. On the soil of each roadway stack chute 6, which provides gravity hydrotransport slurry to verslag 1. On the grounds of corsega 1 also stack means of gravity hydrotransport slurry in the form of a trough, but not one but at least two 7 and 8 (can accommodate 3, 4, 5 or more troughs depending on the number of concurrently developed by hidroponia coal seams). The chute 6 is installed in the passage 3, the corner element 9 connected to the chute 7, installed in Kerslake 1, and the groove 6 is installed in the roadway 4 - chute 8 similarly, organizing thereby two transport chains in the Noah generation - Kerslake 1. At the bottom of the section by extracting coal from the lower reservoir suites form polyphosphoric 10, accumulating the pulp entering the chute 7, and similar polyphosphoric 11, accumulating the pulp entering the chute 8. Between pulmonarily retain hydropathy wall 12.
Coal production from the reservoir, components selection the inventory section, carry out hidroponia. Thus develop two layers (or more)containing coals with different valuable chemical elements. With the working surface of the ledge along the lines of drop formation drill to drift. In the well becoming mounted high-pressure pipe with giant. With the supply of high-pressure water begin to getrootpane coal near drift in the remote control mode monitor. As leaching camera on the effective range of a jet stream becoming pipes cut, removing unnecessary links, thereby raise the monitor up well. Formed in a clearing face of each layer of the flow of pulp through the chute by gravity reach their polyphosphoric, never mixed. From polyphosphoric slurry pump pumped to the surface for subsequent recovery of valuable chemical elements.
Forming on the bottom two (or more) of the storage polyphosphoric. and transportation of gravity of the two (the more threads simultaneously develop two (or more) layer with different concentrations of valuable chemical elements as the number, and the quality. This allows during the summer period of the year to use the power of water for the development of coal seams.
Thus, the development of coal deposits will be excavated stocks, usually do not develop slit, as raw material for the production of valuable chemical elements contained in coal seams, components selection inventory section; will be used stope bottom section to accumulate slurries of different compositions. The above demonstrates the complexity of the development of the coal Deposit. The use of hydraulic mining method coal allows you to organize almost deserted recess, because during getrootpane coal and its transportation troughs does not require the presence of staff or in a mining face, nor in the transport workings. Divide the bottom part of the section on multiple storage polyphosphoric in conjunction with the organization of several gravity transport streams, enables simultaneous mining of coal seams of varying quality, indicates the efficiency of field development, and this is the purpose of the invention.
