Study on the technology for predicting coal and gas outburst through the electromagnetic emission method in chengzhuang mine
In view of Chengzhuang Mines specific problems,the article experimental study composite coal and rock Electromagnetic emission (EME) regularities in the progress of damage.Coal mines EME signals produced by coal and rocks during excavation in Chengzhuang mine were measured with the KBD5 EME monitoring equipment.Then,the relationship between the risk of coal & gas outburst and indicators of conventional forecast & EME is built.The EME forecasting indicator is identified as Emax and the critical value is 10.According to the foregoing conclusions,forecasting technology of coal and gas outburst during excavation in Chengzhnang mine is obtained through analysis.
