摘要
针对E2306综采工作面瓦斯含量高的问题,结合工作面生产地质和瓦斯赋存情况,提出采用“地面压裂井抽采+本煤层抽采+高抽巷抽采”的工作面瓦斯综合治理方案,对各项瓦斯抽采措施参数进行设计。工作面回采期间瓦斯抽采效果监测结果表明:瓦斯综合治理技术实现了对工作面瓦斯的有效治理,为工作面安全回采提供了保障。
Aiming at the problem of high gas content in the E2306 fully mechanized mining face,combined with the production geology and gas occurrence of the working face,a comprehensive gas treatment of“surface fracturing well extraction+coal seam extraction+high drainage road extraction”is proposed.Plan,design the parameters of various gas drainage measures.The results of monitoring the effect of gas drainage during the working face's recovery show that:the comprehensive gas treatment technology has realized the effective control of the working face's gas and provided a guarantee for the working face's safe recovery.
