摘要
微山金源煤矿1341孤岛工作面具有冲击地压倾向性,通过煤层预注水,借助电磁辐射仪和钻屑法监测,采取钻孔卸压和爆破卸压等综合防冲措施,实现工作面安全顺利回采,并取得了良好经济和社会效益。
The No.1341 coal mining face in a seam island of Weishan Jinyuan Mine had the mine strata pressure bumping in potential.With the water pre-injection in the seam and the monitoring and measurement of the electric magnetic radiator and drilling cutting method,the borehole pressure releasing,the blasting pressure releasing and other comprehensive bumping prevention measures were applied.Thus the safety and successful mining could be conducted for the coal mining face with good economic and social benefits.
