Research and Application of Regional Outburst Risk Prediction Based on Gas Content Method
[摘要] The prediction of regional outburst risk is an important guarantee to strengthen the pertinence and effectiveness of the outburst prevention measures and improve the economic benefits of the mine. Based on the analysis of the law of gas occurrence in working face, this paper puts forward the method of predicting regional outburst risk with gas content as the prediction index, determines the critical value of the index, and using this method to predict outburst risk in working face. The field practice shows that the gas content method based on the results of regional prediction and pertinence of outburst prevention measures, reduce the outburst prevention drilling engineering quantity, the regional gas control to reduce costs, the production time is shortened, precision achieved mine outburst prevention, good results have been achieved, the method is applied in the coal mine.
