(54) METHOD FOR DEVELOPING THE MINE OF USEFUL MINERALS

R

The invention relates to mining, in particular to underground mining methods.

There is a known method of preparing the bottom of a block, in which the m.muchy duchek windows at the level of the heel of the scab trenches are placed along its length in row 1.

There is a known method for the development of mineral deposits, in which the output, passed in the bottom, e, is secured by sections of lift-down lining 2.

The disadvantage of this method is the large amount of labor involved in the erection of elevated sectional lining.

The purpose of the invention is to reduce the labor intensity at the release of the mineral and to improve the ventilation of the delivery generation.

This goal is achieved by the fact that, after the ore is completely discharged from the duchka, the subsequent duchka passes in contact with the latter, the ore from the sinking of the duch being drilled is placed in the previously passed, after which it is fixed with a hardening solution, then the cycle of work is repeated.

The method is carried out as follows.

In the lower substage, delivery delivery is made, from which a hole is drilled to form duchek. After duchek formation, the previously broken off ore of the upper substage is produced on the base of the mine. After the ore is completely discharged from the grab, it is secured. Two rows of logs are placed on the graft base and hydraulic racks are installed, then an insulating bridge is installed in the discharge box. After that, in contact with the first duchka form the next, and the mountain mass of it is placed in the previous duchka.

Using this method reduces costs by reducing

5 volume rifled and preparatory work.
