微震监测技术在煤矿工业场区高边坡稳定性监测中的应用

Application of micro-seismic monitoring technology in stability monitoring of high slope of coal mine industrial site

针对煤矿生产影响范围内的高边坡在自然环境和地质应力作用下产生的滑坡或者崩塌等地质灾害造成的人民生命和财产损失等问题,安徽万泰地球物理技术有限公司创新应用微震监测系统对中煤华晋集团晋城能源公司里必煤矿(以下简称“里必煤矿”)工业场区高边坡进行监测,继而及时消除里必煤矿安全隐患。介绍了里必煤矿工业场区高边坡的工区概况以及微震监测系统的构建,通过高边坡稳定性空间域和时间域分析了里必煤矿高边坡稳定性微震监测效果,通过高边坡的损伤程度以及高边坡潜在的滑移面阐述了微震监测系统在高边坡稳定性监测应用中的效果。实际应用表明,微震监测系统能够对高边坡内部稳定性状态监测提供技术支撑,能够实现对即将发生边坡失稳的区域进行早期预警,对煤矿高边坡稳定性危险防范具有较好的借鉴意义。

In view of the problems of people's lives and property losses caused by geological disasters such as landslides or collapses on high slopes within the influence scope of coal mine production under the action of natural environment and geological stress,Anhui Wantai Geophysical Technology Co.,Ltd.innovatively applied micro-seismic monitoring system to monitor high slope of coal mine industrial site and timely eliminate potential safety hazards.This paper introduces the general situation of high slope of coal mine industrial site in Libi Coal Mine of China Coal Huajin Group Jincheng Energy Company and the construction of micro-seismic monitoring system.The micro-seismic monitoring effect of high slope stability in Libi Coal Mine is analyzed through the space and time domains of high slope stability,and the application effect of micro-seismic monitoring system in the monitoring of high slope stability is expounded through monitoring the damage degree of high slope and the potential slip plane of high slope.The practical application shows that the micro-seismic monitoring system can provide technical support for the monitoring of the internal stability of high slopes,and can realize early warning of the areas where slope instability is about to occur,which has good reference significance for the prevention of high slope stability hazards in coal mines.
