    专利说明:

    The invention relates to the mining industry, namely to the means of extracting minerals from underground mining enterprises. Coal mining devices are known that include a housing equipped with cutting nozzles and a splitting-cleaving device. The device is characterized by insufficient efficiency of the destruction of coal. The closest to the technical essence and the achieved effect to the proposed is a mining device for mining, including two planes, each of which is located on the corresponding guide for moving along the bottom fj. The disadvantage of this device is that it also does not provide a sufficiently effective fracture. coal due to high energy intensity of destruction, since the excavation is carried out by mechanical cutting tools. The purpose of the invention is to increase the efficiency of destruction of coal by reducing energy intensity. This goal is achieved by the fact that in a mining device for mining, including two plows, each of which is located on a respective guide for moving along the bottom, one of the plows is made with hydraulic cutting nozzles. The second plow is equipped with cutting nozzles. The device contains in the hydraulic system a radial-piston pump connected with the driving engine, and has a collector and water intake. FIG. 1 shows a hydraulic mining device, front view; in fig. 2 - the same, top view; in fig. 3 and 4 are the same, the plow is combined with a hydraulic machine, cross section and front view; in fig. 5 - the same, perspective view; in fig. 6 — power system of the mining device, partial section; in fig. 7 - the same, option. The mining machine 1 is mounted on the guide 2, mounted on the downhole side of the scraper conveyor 3, and moves along the conveyor, i.e. along the sewage treatment plant. This is accomplished with a conventional chain drive, rack and pinion drive or the like, and in the latter case, the drive is mounted on a mining machine. The mining machine, made in the form of a plow, has a plurality of high-pressure cutting nozzles 4 arranged one above the other and is adjustable in height and / or angle of rotation. The body of the mining machine includes an electric motor 5, a high pressure pump 6 and a tank 7 for pressurized water. A guide chute 8 is attached to the conveyor on the side of the tab (depleted space) to accommodate the power cable 9 and the hose 10. Low pressure water is supplied through the hose 10 and the cable is designed for the electric motor 5, which in turn is used to drive the pump 6. In the operating time of the hydraulic machine 1 moves along the bottom hole, and the high-pressure water jets 4 emerging from the cutting nozzles are cut by cutting. The loading of coal is carried out with the help of loading surfaces 11 in the form of plowshares through guide 2 to the conveyor 3. The hydraulic mining machine, schematically represented in Fig. 1, And 2, is used in conjunction with at least a mechanical mining machine, in particular with a coal plow. In this case, the hydraulic mining machine may be used only as needed for example; in disturbed areas of the reservoir or work along the entire length of the lava so that, for example, remove the outer layer of coal or rock formation and / or free the formation from internal pressure to ensure plow mining. In the embodiment of FIG. 3 and 4, the mining machine in the form of a plow 12 is equipped with a mechanical mining tool 13, moves along a rail 2 fixed on the conveyor 3. The plow 12 is driven in a known manner using an endless pulling chain, a pulling branch 14 and a single 15 in guide 2, respectively, in the lower and upper channels. The hydraulic mining machine 1 moves above the plow 12 along the guide rails 16 and 17, of which one is on the sides of the bottom and the other on the side of the bookmark. Also, the housing from the machine 1 and the high pressure pump for receiving pressure fluid together with the pump drive. The hydraulic mining machine 2 is provided with cutting nozzles 4 that are staggered one above the other and in this case shears off the top pile of the formation 18: while the plow 12 leads the production of the bottom formation stack. The hydraulic mining machine 1 can move along the bottom independently of the plow 12. In the present embodiment, this is done by driving an infinite loop 19 passing in the chain channels 20 and 21 located on the side of the conveyor facing the tab. The mining machine covers the portal jet 22 with a conveyor and is connected with a pulling branch 19 in the upper chain channel 20. In addition, two channels 23 and 24 for the hose 10 and cable 9 are provided on the side of the tab on the conveyor. In the embodiment of FIG. 3, the hydraulic mining machine is used to excavate the top coal pack, and coal loading is carried out by jet 1 2. If necessary, the mining machine 1 and the plow 12 can also be combined into a single machine, which is carried out using a collapsible connecting unit 23 (FIG. . four). In this case, a single device, can be moved along the clearing of the drive, located on a hydraulic machine and / or plane. It becomes possible to equip the jet 12, in addition to its mechanical tools, to high pressure nozzles fed by high pressure water from a hydraulic mining machine 1. In FIG. 5 shows a hydraulic mining device, made according to the type of hydraulic plow. In this case, the mining machine 25 with its casing moves along the guide 2 of the conveyor 3, which faces the clearing face. It spans the conveyor 3 with the boom 22 and rests on the guide rail on the side of the pledged space. On the side of the conveyor facing the pledged space, between the protruding limiting plate 26 and connected to it, the crushers 27 are made one over the other two channels 28 and 29, of the lower channel 29 serves as the feed channel, and the upper channel 28 serves for supplying electric current to the pump drive. On the boom 22 of the mining machine 25 on the side facing the laid space there is a high pressure pump 30 with an electric drive of the pump 31. The high pressure pump 30 is designed as a multi-piston radial piston pump. The boom 22 is provided with a current collector 32, which enters the top of the conduit 28 and is in slidable contact with the current buses 33. The current collector 32 is electrically connected 34 to the motor 31. The current collector passes through the gap between the elastic seals 35 that clamp the channel on the upper side . When explosive underground mining in channel 28, for example, due to the supply of compressed air or nitrogen, an overpressure is created so that outside air enriched in CH cannot enter the channel. The lower water supply channel 29 is open from the side, the intake device 36 enters the side a channel 29 into which water is supplied under low pressure. Through the intake device 36, the high pressure pump 30 sucks in water. The pressure side of the high-pressure pump 30 is connected by pressure lines or channels located inside the boom 22 and the plow body. FIG. Figure 7 shows the structure in which the mining machine 25 moves along the clearing slab by means of a gear with a rack. In this case, the mining machine has an additional electric drive with at least one drive gear 37, which is included in the toothed rack 3S, or another pinching gear, mounted on the conveyor 2 from the side of the paving space. Such an embodiment of the mining device allows to increase the effect (1) of the coal destruction efficiency, since the energy consumption (Ill, 20) the bone of destruction is significantly reduced due to the use of cutting nozzles.
