摘要 为了应对北洺河铁矿矿区周边民营小矿山的超层越界开采导致的经济损失与安全隐患问题,结合采掘工程布局与潜在的越界开采区域,设计了一套16通道微震监测系统,并经安装、调试、精度校准后完成了成套系统建设。利用建成的微震监测系统,对目标区域进行了远距离、不间断、实时在线监测,并对监测的微震事件在时间、空间上的活动性进行了统计与分析,证实了矿区周边民营小矿山的越界开采现象。已建成的微震监测系统空间定位精度达到15m,能准确反映目标区域内采掘生产在时间、空间上的活动性,微震监测判定的越界开采区域位置与现场实际高度吻合,达到预期应用目标。 To solve the economic loss and safety issues caused by over boundary mining activities of small private mines around Beiminghe iron mine,a set of 16-channel microseismic monitoring system was designed based on the layout of mining engineering and the potential over boundary mining areas.After installation,debugging and precision calibration,system construction was completed.Then the microseismic monitoring system was used to carry out the remote,uninterrupted and real-time on-line monitoring on the target area.And the time and space activities of the monitored microseismic events were counted and analyzed.The phenomenon of over boundary mining in small private mines around the mining area was confirmed.The spatial positioning accuracy of the established microseismic monitoring system was up to 15 m,which can accurately reflect the time and space activities of mining production in the target area.The location of over boundary mining area determined by microseismic monitoring was consistent with the actual height of the site,which achieved the expected application goal.
