METHOD FOR CONTROL OF CONDITION OF MASSIF OVER DEAD MINES

摘要

Method for control of condition of massif over dead mines includes coal extraction and breakage of ceiling rocks. Artificial increase of fracturing and hollowness of broken rocks is formed by energy of powder gases in preliminarily drilled wells from surface, artificial disorientation of blocks of rocks that are broken is performed with explosion of liquid explosive substance, and fixation of rocks that have not been broken is performed by synthetic compound SKAT.
