摘要
针对杨涧煤矿1096101复采工作面煤层部分被小煤矿采空,采空区潜在水害气害,煤层自然发火,回采时将引起的上部开采煤柱失稳,造成工作面大面积来压等情况,通过对工作面空洞位置进行探测,提出巷道、工作面过空洞顶板管理措施。
Aiming at the problem of recovery mining 1096101 working face in Yangjian Coal Mine which had been mined by small coal mine, gas disaster and water disaster existing in the goaf, coal seam spontaneous combustion, the instability of upper mining pillar, roof pressure on wide area etc. the paper puts forward the roadway and roof management measures by detecting the goaf.
