摘　　要：微震监测技术已经广泛应用于矿山地压监测,微震活动分析常被用于评价岩体的稳定性情况。微震监测系统可检测到岩石破裂信号,也可以检测到爆破振动信号和其它噪声信号。文章针对系统检测到的爆破事件信号与微震信号,基于黄土坡铜锌矿实际施工情况,对爆破扰动和微震活动在时空方面的相关性进行研究。研究表明爆破活动是微震活动发生的主要外因之一,关键位置的爆破活动是微震事件聚集的诱因,采用充填法可很好地控制地压活动水平。Microseismic monitoring technology has been widely used for ground pressure monitoring in mining process and analysis of microseismic activity is often used to evaluate the stability of rock mass. Microseismic monitoring system can detect rock fracture signals,blasting vibration signals and other noise signals. In this paper,based on the detected blasting event signal and microseismic signal,combine with the actual construction of the Huangtupo copper and zinc mine,the correlation between blasting disturbance and microseismic activity in space and time is studied. The results show that blasting activity is one of the main external causes of microseismic activity,and the blasting activity is one key reason for the inducement of microseismic events. Moreover,the filling method can be used to control the activity of ground pressure.
