微震监测技术在大采深矿井防治水中的应用

Application of microseismic monitoring technology in prevention and control of water in large mining deep mine

根据大采深矿井突水涌水量变化过程中微震监测事件分布情况,间接观测地下水涌出对底板岩层的反应,通过不同层位微震事件的特征和时空发展规律,研究微震技术在深部异常动态监测中的作用,并以此作为依据,指导回采过程中底板水害防治和突水发生后治水工程的开展。

According to the distribution of micro-seismic monitoring events in the process of water inrush change in large mining depth mine,the response of groundwater inrush to floor rock strata was indirectly observed.Through the characteristics of micro-seismic events in different horizons and the law of space-time development,the role of micro-seismic technology in the dynamic monitoring of deep anomalies was studied and used as a basis to guide mining.The prevention and control of floor water damage and the development of water control works after the occurrence of water inrush were carried out.
