METHOD OF MINING MEDIUM-THICKNESS GENTLY SLOPING AND INCLINED COAL SEAMS

机译:中厚煤层轻度倾斜煤层开采方法

摘要

FIELD: mining, particularly, technology of mining of gently sloping and inclined coal seams. SUBSTANCE: method includes panel system of mine field preparation with extraction of panels by long pillars along the same strike; stage division of mining extracted areas in braking incline and raising slope parts of mine field and block mining of stages in direction of braking incline or raising slope. Each block in stage is extracted by pillars with scraping of coal broken by drilling and blasting methods by blast-hole explosive charges from cross holes driven in each extraction pillar of block parallel to stage drifts. Coal is scraped by scraper plant whose end unit is fixed to suspended wire rope secured in vent drift. EFFECT: control of rock pressure, manless mining. 3 cl, 2 dwg
