Abstract

The invention relates to the extraction of minerals by the underground method, namely to the fastening of working faces. The goal is to increase the reliability of work by reducing the work on stripping the working space of the lining from shtyb. The shaft support section includes an overlap (П) 1 with a guide groove 2, hydraulic posts (ГС) 3, attached on one side to the side portions П 1, and on the other to the side portions of the base, between which is located the middle part of the base with rigidly fixed bracket. At the same time, P 1 has a longitudinal groove 20 under HS 21 of attachment of an additional P 11 to the middle part of the base. Hydraulic cartridges 22 of the active bearing P 11 and hydraulic jack / GD / 23 are installed on the П 1 for shifting П 11. On the downside of the bracket there is a vertical guide groove for an additional guide protrusion of the horizontal plate 8, which has bevels 9 on the bottom end on the sides and rigidly attached at one end to the bottom of the lower end of the enclosure. As the coal is excavated to the depth of entry of the excavation unit, the thrusters in HS 3 are successively removed and P 1 is shifted using DGs fixed in the lateral parts of the base and DG 23. After shifting P 1 and the lateral parts of the base, HSS 3 is discharged. This HD 18 of the cantilevers 17 is constantly under fluid pressure, which ensures that they are pressed against the top of the formation during the whole coal extraction process. The lining section reduces the use of manual labor to clean the rock that has collapsed from the roof to the working space. This is achieved due to the fact that during the shifting of the P 11 and the middle part of the base, the plate 8 is in an elevated state and ensures the rock passes into the developed space, and the chips 9 ensure its directional movement towards the dam. 5 il.

This successively removes the thrust in, HS 3 and makes shifting of П 1 with the help of DG fixed in the lateral parts of the base and DG 23. After shifting P 1 and the lateral parts of the base, disassemble the HW 3, At the same time DG 18 consoles 17 are constant pressure of fluid, which ensures that they are pressed to the top of the reservoir during the whole process of coal extraction. The lining section reduces the use of manual labor to clean the rock that has collapsed from the roof to the working space. This is achieved due to the fact that, when moving P P P and the middle part of the base, the plate 8 is in an elevated condition and ensures the rock passes into the developed space, and the bevels 9 ensure its directional movement towards the dam. 5 il.

The invention relates to the field of dooychy minerals by the underground method, namely the fastening of stope faces.

The purpose of the invention is to increase the reliability of work by reducing the work on cleaning the working space of the lining,

the sides and rigidly fixed at one end to the lower part of the lower end of the fence, installed on the dam side of the lining section and equipped with an additional hydraulic cylinder 10 fixed to it at one end, which with the second end is attached to the additional overlap 11. The overlap 11 is located in the slot 2 of the overlap 1, an upper part 12 of the barrier is rigidly attached to its end, which is connected to the lower part 15 of the fence by a vertical guide groove 13 under the guide vertical projection 14. Upper 14 and lower 15 parts form a barrier.

Additional overlap 11, as well as overlap 1, are provided with consoles 16 and 17, respectively, pivoting from hydraulic jacks 38 with respect to their installation axes 19. Overlap 1 has a longitudinal groove 20 for a hydraulic post 21 securing additional overlap 11 to the middle part 5 of the base. In addition, hydrop cartridges 22 are installed on the overlap of the active overpressure of the additional overlap 11 and the hydraulic jack 23 for shifting the overlap of J1.

The side parts of the 4 base and the middle part 5 of the base are attached.

respectively through the hydraulic jacks 24 movement and hydraulic jack 25 movement to the conveyor 26.

Section mine mechanized lining works as follows.

In the initial position overlap

I and additional overlap 1 are arranged so that their cantilevers 17 and 16 are located along one line along the clearing slab 27 by the front ends. As the coal is dredged, the depth of the excavation unit (not shown) is sequentially removed

in the hydraulic pillars 3 and the floors 1 are shifted with the help of hydraulic jacks 24 fixed in the side parts of the 4 bases, as well as with the help of hydraulic jacks 23. Moreover, the additional overlap

I1 is pressed to the roof of the formation by a hydraulically resistant 21 and an additional hydraulic cylinder 10.

After shifting the overlap of the 1 and side parts 4 of the base, hydraulic legs 3 are placed. Hydraulic jacks 18 of the cantilevers 17 are constantly under fluid pressure, which ensures that the cantilevers 17 are pressed against the roof of the formation during the whole coal excavation process.

After the coal is excavated to the depth of the excavation unit, along the entire length of the cleaning hole 27, the conveyor 26 is moved close to the cleaning hole line 27 by means of hydraulic jacks 24, which extend the rods 28. At the same time, the additional hydraulic cylinder 10 works to reduce, which ensures lifting plate 8. The uniform movement of the plate 8 is ensured by the directional movement of the protrusion 7 in the vertical guide groove 6 of the bracket of the middle part 5 of the base and the directional movement of the vertical guide The protrusion 14 in the guide groove 13 of the damming part 12 of the barrier 15 additionally covers 11.

The movement of the conveyor 26 to the clearing line 27 is accompanied by the movement of the extenders 29 of the rods 30 of the hydraulic jacks 25, which work to freely extend the rods 30. After the movement of the conveyor 26 and the reduction of the hydraulic cylinders 10, they remove 1 of the additional rails 11.

I, together with the plate, the middle part 5 of the base, the hydraulic cylinders 10 and the hydraulic legs 21 move to the clearing line 26. At that, 10 the additional overlap 11 moves with active support due to the operation of the strut of hydraulic chutes 22,

8 the state of the active backwater is also the console 16 of the additional 15th overlap 11 due to the work on the ratchet of the hydraulic jack 18. The longitudinal groove 20 of the overlap 1 ensures unimpeded movement of the oversize hydrostock 21 of the overlap. eleven.

20 After shifting the middle part 5 of the base, together with the additional overlap 11, hydraulic struts 21 and 10 are spread. Thus, the shaft section

25 mechanized support reduces the use of manual labor to clean up the rock that has collapsed from the roof into the working space, since when the additional floor 11 and the middle part 5 of the base are shifted, the plate 8 is in an elevated condition and allows the rock to pass into the developed space and the bevels

9 provide its directional displacement towards the dam.

This is especially important since the construction of the section of the mine mechanized lining provides for its use in coal mining with the laying out of a goaf. For this purpose, the fence 15 is provided with sealing plates 31 made of an elastic material, and a pipe 32 is attached to the additional overlap 11 to provide 45 components of the artificial array 33.

The shaft lining section ensures good maintenance of lateral rocks due to timely pick-up.

Thus, the proposed construction of the section of the mine mechanized support ensures its use in complex geological and geological conditions - strong rock pressure, unstable roofs.
