Monitoring And Control Technology Of Research On The Rock Burst In Longjiapu Mine

In this paper, LongJiapu coal mine rock burst prediction and prevention were discussed in detail, pointed out that as Chinese coal mining depth increasing, the coal buried deep and complex geological structure-induced stress have become major rock burst factors. The method of electromagnetic radiation and drilling bits were used to predict rock burst. Firstly use the electromagnetic radiation method to predict danger of burst, and then drill in danger of regional impact to test the degree of risk.This comprehensive approach can make forecasts more accurate, save time and improve the face forward speed. For rock burst occurred on the emerging regions, The drilling of the relief measures for local was taken to relieve danger. The software Rock Failure Process Analysis (RFPA2D) was used to simulate the scope of relief of a single drill to make the program of drillhole pressure relief more reasonable, and had got better results in the on-site applications. In this paper, a realistic prediction and prevention of rock burst way was proposed based on LongJiapu coal mine's background, and it can be the reference for other mining under same conditions to predict and prevent rock burst.
