摘要
对某煤矿3号煤层顶板岩层的含水情况、带压开采情况进行了分析。对该煤层存在的水害问题,综合运用顶板水疏放措施、物探钻探技术以及水害预警监测系统等措施进行治理和预防,为该煤矿3号煤层的顺利开采提供了保证。
This paper analyzes the water-bearing condition and Mining under pressure of roof rock in No.3 coal seam of a coal mine.In order to control and prevent the water disaster in this coal seam,the measures of roof water drainage,geophysical drilling and water disaster early warning and monitoring system are comprehensively used to ensure the smooth mining of the No.3 coal seam.
