| Abstract: | According to practical geological conditions of No.3 coal seam in Zhaozhuang mine,four predicted sensitive indices for gas outburst risk were selected.Through field test and comparative analysis of the sensitivity of the various indexes,the sensitivity of drilling bits method was relatively high for gas outburst risk prediction for No.3 coal seam in Zhaozhuang mine.Based on index predict results of drilling bits method,mine safety tunneling was obtained. |
