摘 要:古书院矿94304工作面在回采过程中,采空区上覆岩层随着支架的移动垮落,采空区的瓦斯涌入回风隅角和回风巷,造成瓦斯偏高,影响正常生产。为确保该工作面正常回采,制定了瓦斯治理方案,概括为“防、堵、疏、排、截”。根据回采情况分析,这些措施解决了工作面回风隅角瓦斯超限问题,实现了高产高效安全生产。During the recovery process of the 94304 working surface of the ancient Academy mine, the overlying rock layer in the mining area collapsed with the movement of the brackets, and the gas in the mining area flooded into the windward corner and windward lane, causing high gas levels and affecting normal production. In order to ensure the normal recovery of the work surface, a gas management plan was formulated, which was summarized as "prevention, blocking, sparse, platoon, and interception." According to the analysis of the recovery situation, these measures solve the problem of gas limit in the wind corner of the working surface and achieve high yield, high efficiency and safe production.
