微震监测技术在顶板来压预测预报中的应用
|
摘要
介绍了微震监测系统在千秋煤矿预测预报顶板来压中的应用情况。实践结果表明,微震监测系统可实现对综放工作面老顶初次来压的预测判断;微震监测与日常钻屑量监测、矿压监测等数据较为一致,采用综合性的冲击地压预测预报技术能更有效地对采场动力灾害进行预测预报;用大能量事件频次作为微震监测系统的有效参数可较准确地对采场动力现象进行预测预报,并总结出顶板来压的前兆信息模式,该项结论能有效预防采场动力现象和冲击地压事故的发生。
The paper introduced application of microseismic monitoring system in forecasting roof weighting of Qianqiu Coal Mine.The practical result showed that the microseismic monitoring system can forecast and judge the first weighting of main roof of fully mechanized caving face;data of microseismic monitoring is consistent with data of drill cuttings quantity and rock pressure monitoring,and using comprehensive forecasting technology of rock burst can forecast stope dynamic disasters more effectively;taking frequency of large energy events as effective parameter of microseismic monitoring system can exactly forecast stope dynamic phenomenon and summarize precursor information model of main roof weighting,and the conclusion can effectively prevent stope dynamic phenomena and rock burst accidents.
