METHOD FOR TRANSITION OF GEOLOGICAL DISLOCATION OF DISJUNCTIVE TYPE BY STOPING FACE Russian patent published in 1996 - IPC

FIELD: mining industry; applicable in mining outburst- prone beds in zones of geological dislocations. SUBSTANCE: method for transition of geological dislocation of disjunctive type by stoping face include measurement of dislocation amplitude, angle of inclination and length of route crossing working dislocation, parameters of location, operation and monitoring the mining complex advance. Novelty consists in that turning of powered mining complex is started at distance from dislocation equalling the length of the protecting part of the bed. Additionally determined are thicknesses of bed and layer of soft rocks enclosing the bed in dislocation zone. Geological dislocation is referred conventionally to one of three groups corresponding to respective conditions with calculated formulas taking into account of dislocation amplitude, thickness of coal seam, minimum thickness of incompetent rocks in seam roof and floor. Crossing of the dislocation by powered mining complex is effected depending on the dislocation group. So, dislocation of the first is crossed by small-step turning of powered mining complex in the vertical plane without blasting of enclosing rocks. EFFECT: higher efficiency. 5 cl, 14 dwg
