倾斜巷道电磁辐射规律分析
nalysis of Electromagnetic Emission Signals of inclined Roadway
根据平煤集团某矿某采区煤层具有弱冲击倾向性和属于中等冲击危险采区这一事实，采用电磁辐射预测预报冲击矿压技术，对该采区掘进巷道进行了冲击危险性预测预报，通过对监测到的电磁辐射信号进行分析，得出沿煤层走向掘进巷道的两帮电磁辐射信号存在较大差异这一结论．通过对巷道两帮电磁辐射信号来源、发生机理以及巷道两帮煤体受力情况进行分析，找出了巷道两帮电磁辐射信号有较大差异的原因和影响因素，根据该项技术分析以及所得出的结论，可通过分析冲击矿压危险巷道的地质条件提前对巷道两帮的冲击危险性作出初步对比判断，从而节约冲击矿压防治成本，促进煤矿安全高效生产．
he coal of a distrct in Pingdingshan Coal Group was proved to have weak burst tendency and mid rock burst danger．The Electromagnetic Emission (EME) technique was adopted to forecast rock burst danger in the roadway of the district．According to the analysis of EME signal，the results showed that the EME signal of the sides of the roadway along bearing of the coal seam are different．By the analysis of the EME signal’s origin，engenderer mechanism and the coal stress state of the roadway’s sides，the reason for the EME signal differences has been found．Based on the EME technique and the conclusions of the study, the rock burst danger of a roadway’s sides can be primarily forecasted with the analysis of the geological conditions，which can economize rock burst prevention measures and ensure coal mine production safety．
