合理的工作面瓦斯治理方案优化是保证工作面安全高效开采的核心和关键,针对临涣煤矿近距离突出煤层群瓦斯治理存在的问题,以东翼7134工作面为例分析比较了3种瓦斯治理方案。通过分析论证,确定适合该采区目前条件下的最优开采程序,并对回采工作面的瓦斯治理进行设计。
Reasonable working face gas control scheme optimization is the core and key to ensure safe and efficient mining face. Aiming at the problems existing in gas treatment of coal seam group with close distance in Linhuan Coal Mine, the paper analyzes and compares the three kinds of gas treatment Program. Through the analysis and demonstration, the optimal mining procedure suitable for the current conditions of the mining area is determined, and the gas treatment at the mining face is designed.
