摘要:
微震监测系统对岩体发生非弹性变化造成的微震事件进行实时监测，能及时做出岩体的失稳预警，保证矿山的安全开采。根据东升庙铅锌矿的采空区的实际赋存情况，提出了布置9个检波器的监测方案，通过对该方案进行室内模拟，分别对Vert1 和Vert2及其整体性进行定位精度分析，分析可知该方案是合理的。矿山构建IMS微震监测系统后，采用人工爆破定位的方法来确定该监测系统定位的准确性，通过对实测坐标和微震数据处理软件分析的坐标进行对比分析，可知该监测系统的精度是12m左右，能够实现矿山采空区的稳定性监测，满足矿山安全生产的要求
Abstract:
Microseismic monitoring system can real-time monitor the seismic events caused by rock mass with inelastic change, and timely makes instability warning of rock, so as to ensure the safety mining of mine. According to the actual occurrence of goaf in Dongshengmiao leadzinc mine,a monitoring scheme of decorating 9 detectors was proposed. Based on the scheme for indoor simulation, the respective analysis on location accuracy to Vert1 and Vert2 and the whole of them was conducted, which showed that the scheme is reasonable. After IMS microseismic monitoring system was constructed in mine, the method of artificial blasting positioning was applied to determine the positioning accuracy of the monitoring system, through the comparative analysis of the measured coordinates and the coordinates analyzed by seismic data processing software, it showed that the monitoring precision of the system is 12 m or so, which can realize stability monitoring of the mine goaf, and meet the requirements of the mine safety production.
