Description

one

The invention relates to the mining industry, in particular to methods for constructing a mine jumper,

The purpose of the invention is to increase the safety of operations when using a lintel in a mine workout to prevent sudden breakthrough of mine water and to obtain a statically stable mine lintel structure.

FIG. 1 shows the installation of a drainage-reinforcing system and a self-impermeable bridge, FIG. 2 is a diagram of a method for mixing a dry cement-sand mixture using needle filters of a drainage-reinforcing system, FIG. 3, a mine bridge across the mine, FIG. 4 drainage-reinforcing system, isometric,

The shaft bridge, consisting of the cruciform sections 1 of the drainage-reinforcing system, installed across the mine workings, is fastened with the help of screw jacks 2 into the walls of the mine, thus ensuring the stability of the system in the required place. Then, under the protection of the waterproofing sheet 3, packages (4) filled with dry cement-sand mixture (based on expanding sludge of tension cement) are laid (incandescent) onto the drainage-reinforcing system and their further closure.

The waterproofing sheet 3 is closed to prevent direct contact of the body of the lintel with water, it prevents the cement from being extruded from the packaging element.

Comrade, and. also ensures safety 40 When installing drainage-reinforcing

mine bridge forms at the time of setting and hardening of concrete. Under the protection of the waterproofing sheet, the process of mixing and swelling of the mixture contained in the packs is controlled using shut-off valves (valve 5 with

sides of the hydrostatic pressure, valve 6 - with reverse), Block 1 of the drainage-regenerating system is made of cruciform sections 7, consisting of inlet 8 and outlet 9 nozzles and drainage pipe 10, to which reinforcement 11 and needle filters 12 are welded.

The needle filters communicate with the drainage pipe 10 to pass water into the body of the web.

The needle filters simultaneously play the role of reinforcing elements and serve to supply water to the bags with the dry mix. Mixing the mixture in bags is possible in two ways. The first one is using WATER through the needle filters from the fixed space, the second one using the water pressure from the water mine network through the same block of the drainage-reinforcing system and the needle filters in the body of the already constructed shaft lintel arranged in advance.

The rate of mixing of the mixture in the packets is regulated by means of block valves of the block.

The proposed method of constructing a mine jumper (such as a barricade or a deaf bezrubova) allows a short period of time to prevent the threat of flooding of mine workings. The method provides for the transition from a sorrow to the blind by installing on blocks of telescopic needles, and also assembling along the length of production to increase the thickness of the lintel.

The units on the basis of the mine carriages platforms with the corresponding reserve of package elements are made mobile. The construction of jumpers by the proposed method allows to reduce the time for their device by 30-40%,
