针对山西某矿盘区大巷受应力集中影响处于高应力状态,巷道支护困难,多次出现片帮、底鼓、U 型钢支架被推倒等动压现象,受到冲击地压威胁,将微地震监测技术应用于该大巷对其顶板岩层破断情况进行监测,共安装2 台分站和18 个测点,以实现对该区域内冲击地压灾害进行监测预警。2014 年2 月1 日至3 月16 日的监测结果表明,监测区域内每日微震事件发生0~4次,事件能量较小,微震事件集中在2 个区域,与现场采掘活动密切相关,因此应加强微震事件密集区的监控,如果出现异常应立即采取停产卸压等应对措施。

The panel roadway in a coal mine in Shanxi province was in high stress state by the influence of stress concentration with dynamic pressure phenomena appearing, such as supporting difficulty, spalling, floor heaving, U-steel support pushed and threatened by burst. Microseismic monitoring technology was used for monitoring the roadway roof strata breaking. Two sets of sub-stations and 18 measuring points were installed to monitor and warning the burst disasters. Monitoring results showed that microseismic events occurred 0-4 times per day in the monitoring area with less energy. The microseismic events were concentrated in two areas, and were closely related to the extractive activities. More attention should be taken to these areas, monitoring of densely populated areas with microseismic events should be strengthened, and measures should be taken immediately to cope with abnormal events.
