METHOD FOR CONTROL OF ROCK PRESSURE IN MINERAL MINING AT LARGE DEPTHS

摘要

FIELD: mining, particular, underground mining of mineral beds at large depths with the help of plowing units. SUBSTANCE: method for control of rock pressure in mineral mining at large depths includes, first, determination of mineral bed thrust at edge of stoping face at different points along the face, and filling of worked-out space is effected before roof rock caving. Rigidity of filling mass along the face length is taken variable in compliance with the law analogous to the law of variation of the bed thrust intensity at the face edge. EFFECT: higher efficiency of stoping operations due to reduced emergency situations in breakage face associated with curving of the face line in the process of mining. 3 cl, 1 dwg
