NEW TYPE POWER SUPPORT SECTION: MOVABLE HYDRAULIC VALVE IN SIDE ROCK AND THE LOCK IN THE THERMODYNAMIC BALANCE CAPSULE
New type power support section is reviewed in conception of interaction with geomechanical processes in the rock massif, exactly in the thermodynamic balance capsule. The novelty in comparison with similar domestic and foreign developments is in the fact that geomechanical system “support-rock massif” is put into balance condition, which increases the mining works safety at a coal extraction face.
