METHOD DEVELOPMENT inclined coal RESERVOIR

摘要

FIELD: mining.;SUBSTANCE: proposed method comprises preparation of mine field by poles on Longwall Retreating on the Strike development system using the mechanised breaking complexes (MBC). Exposing diagonal workings with inclination angles is performed within the specs of minerals conveyors. Coal is excavated in long breaking coal face with reverse stroke with production of mounting chamber, dismantling chamber, complex and inspection at reassembly and wok site. Rock pressure is controlled by rock cover ball in worked-out area. Mine waters are collected at lower points of the mine. Water solution of antipyrogenes is fed in worked-out area. Long walls are developed at mining face line aligned with MBC, mounting chamber, dismantling chamber, and inspection chamber parallel with opening at both forward and back direction of mining face.;EFFECT: higher yield of commercial coal and efficiency of MBC use.;4 cl, 6 dwg
