火成岩下开采的冲击监测与防治技术

The Impact Monitoring and Control Technology of Mining Under Igneous Rock

利用SOS微震监测系统对工作面开采过程中顶板及火成岩的运动和破裂状态进行监测,利用软件分析震源的位置和能量,及时发出预警信息。同时采取大直径钻孔卸压、煤层注水、两巷加大超前管理、防崩措施等煤层卸压和顶板管理措施,为10416工作面的开采提供了安全保障。

By using SOS micro seismic monitoring system, it monitored movement and fracture status of the roof and igneous rock in the mining process of the working face. It used software to analyze the position and energy of the seismic source, sent out warning informa- tion in time. At the same time, it took some measures of coal seam pressure relief and roof managemellt, such as large - diameter bore- hole pressure relief, coal seam water injection, two roadways increase advanced management, collapse prevention and so on, which provided safety guarantee for mining in NO. 10416 working face.
