Abstract

A review of literature sources is given, reflecting the effectiveness and necessity of the use of boreholes and boreholes, the mechanism of interaction of the borehole with the surrounding rock mass during the detonation of the borehole charge of explosives, and also the developed design of the locking borehole made of certain materials, such as polypropylene, polymers, etc. The technical result is the possibility of increasing the efficiency of the penetration of underground mining and the improvement of the coefficient the use of boreholes and boreholes.
