摘　　要：冬瓜山铜矿井下岩爆灾害突出,特别是在回采矿柱时极易诱发顶板冒落,给矿山的地压灾害安全管理工作带来挑战。结合冬瓜山铜矿岩爆灾害特征,选定监测区域开展微震监测系统台网设计,提出了基于三维可视化模型空间分区定量化分析岩爆灾害活动的方法。通过对微震数据的时空分布特点、微震事件活动与生产活动之间的相关性进行分析,得到了岩爆灾害控制的有效措施,如调整作业面绕开应力集中区域,优化爆破参数降低对围岩的扰动,及时充填以及提前对危险区域加强支护措施等。通过微震监测技术可以及时掌握岩爆灾害状况,进而为地压灾害安全管理提供科学依据。The underground rock burst disaster in Dongguashan Copper Mine is prominent,especially in the back mining column,it is easy to induce roof caving,which brings challenges to the safety management of mine ground pressure disaster.Combined with the characteristics of rockburst disaster in Dongguashan Copper Mine,the monitoring area was selected to carry out the network design of microseismic mon-itoring system,and the method of quantitative analysis of rock burst disaster activity based on three-dimensional visualization model space partition was proposed.By analyzing the temporal and spatial distribution characteristics of microseismic data and the correlation between microseismic event activities and production activities,effective measures for rock burst disaster control are obtained.For example,adjusting the working surface to bypass the stress concentration area,optimizing the blasting parameters to reduce the disturbance to the surrounding rock,timely filling and strengthening the support measures in the dangerous area in advance.The microseismic monitoring technology can grasp the situation of rockburst disaster in time,and then provide a scientific evidences for the safety management of ground pressure disaster.
