摘要
通过对111301工作面煤层瓦斯赋存及瓦斯来源情况进行分析,采用风排瓦斯、顺层钻孔预抽、高抽巷抽采、上隅角埋管抽采等瓦斯综合治理措施;对工作面初采期间的采空区卸压瓦斯治理进行研究,取得了良好的效果,保证了工作面安全高效回采。
Through the analysis of the 111301 working face of coal seam gas occurrence and the gas source, using the comprehensive control measures of the ventilation, Gas pre-drainage along the Seam, high level suction roadway drainage gas, and drainage gas in the upper comer, studied the gas control measures of working face pressure relief area during the initial mining, which have achieved good results, to ensure the safe and efficient mining working face.
