摘要
以阳城煤矿1304孤岛工作面为例,基于电磁辐射预测冲击地压原理,结合孤岛工作面支承压力分布规律,分析了电磁辐射监测方法及测点布置方式,通过采用以电磁辐射监测技术为核心的多种监测与治理手段,建立了电磁辐射预警→钻屑法危险识别→煤体深孔爆破卸压→电磁辐射卸压效果检验的孤岛工作面冲击地压危险监测与治理技术,并取得了良好的效果。
Taking the 1304 island working {ace in Yangcheng Mine as the example, based on the principle of electromagnetic radiation predicting rock burst and combining with support pres- sure distribution law in island working face, the paper analyzes the electromagnetic radiation mo- nitoring method and layout of measuring points. By using a variety of monitoring and treatment means centered on the electromagnetic radiation monitoring technology, a new technical method of monitoring and controlling for rock burst in island working face is established, including elec- tromagnetic radiation warning, rock burst hazard identification by drilling cuttings method, un- loading pressure by deep-hole blasting in coal and electromagnetic radiation testing the stress re- lease effect, which has obtained good effectiveness.
