煤层顺层钻孔瓦斯预抽是重要的煤与瓦斯突出防治措施,针对采取消突措施后是否可以进行工作面回采作业的问题,以山西平舒煤业有限公司15207工作面为工程背景,通过理论计算和现场实测进行了工作面预抽瓦斯消突效果评价。检测结果表明工作面消突措施效果明显,突出危险性较低,可进行回采作业。 Coal seam gas pre-pumping is an important pre-pumping coal and gas outburst prevention and control measures for the elimination of measures to eliminate the problem of face mining operations back to Shanxi Pingshu Coal Industry Co., Ltd. 15207 face as the project background, through Theoretical calculation and field measurement were carried out to evaluate the effect of gas drainage in front of the working face. The test results show that the effect of eliminating the sudden protrusion on the working face is obvious, the outstanding risk is low, and the mining operation can be carried out.
