(54) METHOD OF PROTECTION OF PREPARATORY WORKS

(57) The invention relates to mining and can be used for

protection workings (B). The purpose of the invention is to increase the reliability and reduce the cost of protection in the conditions of weak lateral rocks (P). At the boundary of the lava along the protected HF, an array of organ supports was erected. Between the rows, additional organ lining was erected with the formation of niches (H). In the formed Hs, the pneumatic cobels are installed, which are then alternately removed after the collapse of P beyond the temporary reference pressure zone. After removing the pneumatic bridge 3, the newly formed H is filled with P 5, which is taken from undermining soil B 4. This makes it possible to further prevent the swelling of P, and the use of P dg bookmarks H prevents their transportation to the surface. 2 Il.

The invention relates to mining, in particular to the protection of preparatory workings of coal and shale mines.

The aim of the invention is to increase the reliability and reduce the cost of protecting workings in conditions of weak lateral rocks.

FIG. 1 shows a portion of the lava adjacent to the drift, plan view; in fig. 2 shows section A-A in FIG. one.

The method of protection of preparatory workings implemented as follows.

As the cleaning works move, behind the lava in the immediate vicinity of the bottom-hole in the berm part of the drift, organ support is erected. Between the rows of organ lining establish additional rows of organ lining 1 with the formation of niches. When forming, roll, metal or polymer tightening 2 is installed in them. Then, the pneumatic coil 3 is installed with a significant initial rupture. After the overburden rocks have collapsed and their subsequent compaction outside the temporary support pressure zone, the pneumo-ostracles are alternately removed to protected production 4 for reuse , and the niches are filled with rock 5, which is taken from undermining the soil. Undermining of the soil makes it possible to prevent the swelling of the rocks, and filling the niches with the rock - to exclude its transportation to the surface.
