摘要
以石圪台煤矿12105工作面为开采背景,通过对开采期间支架压力的实时记录,分别对该工作面过上覆综采采空区、集中煤柱、房柱式采空区以及开采末期时的矿压显现作了详细的监测分析,掌握了不同情况下矿压的分布规律。
By mine pressure observation in 12105 face of Shigetai coal mine, the pressure behavior regulation of fully mechanized mining face was studied in many mining conditions. Field monitoring results show that the pressure behavior was strong when mining face passing over gob that mined by fully mechanized face and the pressure behavior was reduced significantly when the mining face passing over concentrated coal pillar or gob mined with room and pillar mining.
