摘要
煤岩电磁辐射技术可以预测、预报矿井冲击地压。针对跃进矿冲击地压频发生问题,采用电磁辐射预测的方法,详细研究了工作面某处电磁辐射信号的前兆信息。获取了冲击危险前兆信息,检验了卸压爆破的效果。
The electromagnetic radiation（EMR） technology can forecast rock burst.Aiming at the problem that rock burst happens frequently in Yuejin mine,using the method of electromagnetic radiation prediction,the precursor information of electromagnetic radiation signal at working face somewhere is studied in detail.The precursor information of rock burst is obtained and the effect of pressure release blasting is tested.
