摘要
为了减少煤矿突水灾害带来的安全风险,使用微震监测技术设计出 1 种煤矿突水灾害预警系统,并选用地震检波器作为系统中的传感器.使用该系统对顺勋煤矿进行监测,结果显示,该煤矿在监测期间共发生了 193 次微震,其中微震释放能量大于 1 000J的次数为 6 次,单次微震释放的最大能量为 2 455 J,远小于工作面附近出现过的最大微震释放能量,且绝大多数的微震出现在底板下方 12m内的区域.测试结果表明,微震监测技术能有效监测煤矿因突水引发的微震,并提供相应的预警信息.
Abstract
In order to reduce the safety risks caused by coal mine water inrush disasters,a coal mine water inrush warning system was designed using micro-seismic monitoring technology,which uses seismic detectors as sensors in the system.The system was used to monitor Shunxun Coal Mine,and the results showed that a total of 193 micro-seismic events occurred during the monitoring period.Among them,there were 6 times when the energy released by micro-seismic events exceeded 1 000 J.The maximum energy released by a single microseismic event was 2 455 J,which is much smaller than the maximum energy released by microseismic events near the working face.The vast majority of micro-seismic events occurred within 12 m below the floor.The test results indicate that micro-seismic monitoring technology can effectively monitor micro-seismic events caused by water inrush in coal mines and provide corresponding warning information.
