集贤煤矿深部开采强冲击危险煤层冲击地压防治技术

    Rock Burst Control Technology for Deep Seam Mining with High Burst Dangerous in Jixian Coal Mine

    • 摘要: 为了有效防治强冲击危险煤层的冲击地压灾害,在系统分析冲击地压影响因素的基础上,总结了集贤煤矿9#煤层冲击地压的发生特征,进而确定了以微震监测技术为基础,包括爆破强制放顶、浅孔爆破卸压、加强超前支护和煤层注水等技术措施的冲击地压综合防治技术,有效降低了集贤煤矿冲击地压发生的频率和危害,确保了矿井的安全高效开采。

       

      Abstract: In order to control the rock burst disaster of coal seam with high burst dangerous, on the basis of systematic analysis of rock burst influencing factors, rock burst characteristics of coal seam 9# in Jixian Coal Mine were summarized and the integrated control technology of rock burst was formed based on microseismic monitoring technique including forced roof caving by blasting, blasting destressing of shallow hole, strengthening advanced support and coal seam water infusion. The frequency and damage of rock burst in Jixian Coal Mine was reduced effectively and safety and high efficiency wasensured.
