    专利说明:

    The invention relates to a rop: ioivry case and can be used to protect underground cavities from draining water. There is a method of zastachtn underground cavities from the breakthrough of water from the hydro-accumulating layer of rocks, including the preliminary holding of a complex of workings and diversion of water fl. There is also known a way to protect under the earth’s cavities from the breakthrough of water from the pumped accumulator of a whole layer of rocks, including the creation of at least one tap element and the withdrawal of water 2. However, both of these methods do not provide a sufficiently effective preventive protection of cavities when there are between the cavities formed and the pumped storage layer of the water-filled layer of uneven power. The aim of the invention is to provide effective preventive protection of said cavities. The goal is achieved by the fact that the by-pass elements create in the waterproof layer that the water-withdrawing by-pass element is isolated and injected into it under pressure, which is yes and fi, and hardens l: material / in the bypass An element mixed with a water-releasing by-pass element is injected into a solid :: Oi iH i Aternal- which, in the first place, the hardening material is injected} from the element adjacent to the water outlet and after hardening: part of the aether in the adjacent evil; hardening material in water release hole ne element. FIG. 1 shows a general scheme, ia works on the underground workings from the breakthrough of water in the section of the asta; on fkg. 2 - the same dhema in: - cross the strike of the reservoir; on . Figure 3 shows a different I scheme for the underground storage; in fig. 4 - the same schema for the prospect of seam; in fig. 5- diagram 3 а ujT t tunnel from water breakthroughs; b - diagram of another version of the protection of underground workings; on - sched-; and the same option strike the seam a; The diagram of the 8th scheme, along the strike of the reservoir; ka fig. 9 - scheme of borrowing of underground workings in other conditions; tia fig. 10 - the same scheme in the plane of light; in fig. 11 is a diagram of the input material in the bypass element; on
    FIG. 12 is a diagram of one of the variants of the method.
    The method consists in the following: Mineral excavation is carried out by cleaning face 1 with preliminary drifts 2, 3. As layer 4 has a dip angle, 11 track 2 is located below drift 3. A layer 5 of the reservoir is directly adjacent to the reservoir, under which is a pumped storage layer b . In this embodiment of the method, the preventive protection is carried out in such a way that before the cleaning face 1 of the drift road. 2 under the soil 7 of the reservoir 4 bore holes 8. Where the discharge 9 passes, the wells are drilled on both sides of the discharge. The wells 8 create a trap for water, and then water enters the shaft 2 and into the sump.
    Another variant of the method is possible where outlet elements 10 are created directly in the formation. In the elements 10 build pipelines 11.
    Piping is introduced into the WATER COOKER
    the elements, and the elements, not the output of the water where they are, should be driven over with pneumatic installations 12 with granular material 13.
    Under protection of the tunnel 14 in the water layer, bounded by the surface 15 from the pumped storage layer 16, a drift is conducted 17. Parallel to the drift 17, excavation 18 passes, the front of which advances the drift front 17, Production 18 passes above drift 17 and connects it to the last bays 19. Shaft -17 serves simultaneously to remove air, ventilation, and maintenance.
    In another embodiment of the excavation, it is most expedient to drill wells 21 from the deeper drift 20 after the passage and to use them to remove the incoming water, and to drill the wells 8 near the soil 7 of the reservoir 4 before the clearing hole
    Otherwise, the drifts 2, 3 are connected to the main auxiliary drift 22, and the deeper drifts 20 to the dewatering drift 23. Next, the wells 24, 25 are drilled. In the wells that produce the water, injection pipes 26 are introduced compaction materials, Boreholes, that do not exude water, lay the granular material. The lines 20 should always be ahead of the lines 2, 3 when working,
    For supplying hardening material to the well 27, a pipe 28 consisting of sections 29, 30 is inserted into it, at the front end of which there are rollers I, and at the rear end a valve 32 and nozzle 33 of the injection line. The main pipe 28 after opening the valve J2 can hydraulics or with the help of the lead screw to move in towards the incoming water. The main Tpyfia 28 is compacted by the packers 34. The inner cavity of each packer is connected to the injection pipe 35, through which the hardening material is fed. After the material inside the packers 34 has hardened, the annular cavities between the walls of the main pipe and the wall of the branch element are filled with a hardening material by means of the injection pipe 36, and air is exhausted through the pipe 37. After the material B1 is cured, the return pipe is connected to the pipe 33 and the valve 32 is closed.
    First, the injection is carried out in the bypass elements located closer to the point of breakthrough, and only after the material cures, is the injection made directly into the water-releasing element. The injection lasts until an increase in injection pressure is detected due to the onset of solidification of the injected material or the filling of a large cavity and penetration into the small passages that feed it. The injection is carried out under a pressure greater than the pressure of the water entering the outflow element.
    In some cases, tap elements should be located relatively close to each other. In this case, the pillars between the diverting elements are gradually destroyed. In these cases, only one of the two bypass elements is first performed, the ALLOWED of which is filled with sealing material 38. In the material 38 pipes 39 are laid for subsequent injection. Intermediate elements 40 are made only after the material 38 has hardened.
    Allocation sch1: e elements, if necessary, can be expanded by a hydraulic method.
