胡家河煤矿冲击地压微震多参量监测预警研究

Study on microseismic multi-parameter monitoring and early warning of rock burst in Hujiahe Coal Mine

胡家河煤矿402103工作面采掘过程中动力显现强烈,巷道多次破坏,严重制约矿井采掘接续。为解决胡家河煤矿冲击地压问题,采用煤矿冲击地压微震多参量监测预警方法,包括微震活动性综合预警、冲击变形能指数预警等,对胡家河煤矿工作面2016年8月—10月微震数据进行分析,成功预测了402103工作面2016年10月27日的冲击地压显现,保证了矿井安全生产。

In the mining process of 402103 working face of Hujiahe Coal Mine, the rock burst disaster was serious, and the roadway was damaged, which seriously restricted the mining activities of the mine. To solve this problem in Hujiahe Coal Mine, the coal mine microseismic parameter monitoring and early warning method of rock burst was adopted, including comprehensive warning of microseismic activity, bursting energy index, etc..seismic data of August 2016 to October 2016 on working face of Hujiahe Coal Mine was analyzed, and the rock burst in 402103 working face on October 27 was successfully predicted, and the mine safety production was ensured.
