Optimization of Region Outburst Prevention Measures in Single Steep Soft Coal Seam
摘要
Abstract
Aiming at the problems of lacking of mine gas basic parameters, mining deployment unreasonable, pre -pumping measures unreasonable and regional outburst prevention measures imperfect, basic parameters of coal mine gas in Chayuan coal mine were tested. By mastering the gas occurrence laws of mining face, strengthening construction efforts of drainage holes in geological structure, ration- ally arranging the mining face, determining reasonable pre - drainage period of gas drainage, carring out the pre - assessment of out- burst elimination effect in working face, determining the layout principles of test hole, this paper optimized the region outburst preven- tion measures.关键词
