Ground Microseismic Monitoring Technology for Grouting Effect in Coal Mines

微震监测技术是近年来发展起来的有效监测接收煤、岩体受载破坏时引发的微震动,从而推断地下变化情况的一种地球物理学方法,其具有设备简单、对勘探环境破坏较小、可实现连续不间断监测等优势,将其应用于煤矿注浆效果的探测,可以为注浆活动提供一定的理论指导和技术支撑。本文主要对实施地面微震技术监测注浆效果过程中的台阵布设、关键处理技术、AI初至拾取技术、微震动事件精确定位技术的研究进行详细阐述,并结合地质资料对成果进行了深入分析,以期使微震监测技术在未来的应用过程中发挥越来越大的作用。

Microseismic monitoring technology is a geophysical method developed in recent years to effectively monitor the microseisms caused by the loading failure of coal and rock mass,so as to infer the underground changes.It has the advantages of simple equipment,less damage to the exploration environment and continuous monitoring.Its application in the detection of grouting effect in coal mine can provide some theoretical guidance and technical support for grouting activities.In this paper,the key role of micro seismic array technology in the process of geological monitoring and implementation is described in detail,so as to make the micro seismic array technology play a more and more important role in the process of micro seismic monitoring and implementation in the future.
