高瓦斯矿井综采工作面初采瓦斯综合治理措施及效果研究

Study on comprehensive treatment measures and effects of initial gas mining in high-gas mine comprehensive mining face

本文以贵州肥田煤矿210701综采工作面的瓦斯概况为研究对象,提出了应用高负压本煤层抽采、卸压及高位拦截钻孔、低负压抽采和风排瓦斯4种瓦斯综合治理措施,研究结果表明多种治理措施合理有效的联合利用能更大程度的完成瓦斯治理的目标,为贵州肥田煤矿高产高效高瓦斯矿井治理瓦斯提供了一个合理的瓦斯综合治理方法。

This study takes the gas profile of the 210701 comprehensive mining face of Guizhou Feitian Coal Mine as the research object,and proposes four comprehensive gas treatment measures of high negative pressure coal seam extraction,pressure relief and high interception drilling,low negative pressure extraction and air exhaust gas,and the results show that the reasonable and effective combined utilization of multiple treatment measures can complete the goal of gas treatment to a greater extent,and provide a reasonable comprehensive gas treatment method for high-yield,efficient and high-gas mine gas treatment in Guizhou Feitian Coal Mine.
