Abstract:Huashugou copper mine is located in the deep of iron deposit, so its geological structure is complex. In order to master the occurrence process and rules of ground pressure dynamic disaster in Huashugou copper mine, a set of microseismic monitoring system is built in it. The design of microseismic monitoring system is a key step, because the layout of the network will affect the positioning accuracy of microseismic events, and then affect the monitoring effect. In this paper, the main ground pressure hazard area of the mine is obtained by field investigation and rock mechanics analysis. Based on this area, the optimal monitoring design scheme is obtained by using the network design tool, and the design effect is tested by field verification. The results show that the optimal design of microseismic network can greatly improve the accuracy of ground pressure disaster warning.
