摘要: 义棠青云煤业开采2 号和5 号煤层时瓦斯涌出量较大,需要设立瓦斯抽采系统。根据瓦斯来源情况,设计了
瓦斯抽采方法。对于回采工作面,在运输顺槽施工顺层钻孔进行本煤层瓦斯预抽和边采边抽。对于采空区,在2 号、5 号
煤层回采工作面上隅角进行插管抽采。经过计算,瓦斯抽采时间在120 d时可以实现安全开采。

Abstract: Yitang Qingyun Coal Industry Co., Ltd. had a large amount of gas emission when mining No.2 and No.5 coal seams, so
it was necessary to set up a gas drainage system. According to the gas source, the gas drainage methods were designed. For the
stoping working face, the coal seam gas was pre-pumped and pumped while mining by drilling holes along the transport passage.
For the goaf, intubation was performed in the corner of No.2 and No.5 coal seam mining working face. After calculation, the safe
mining can be realized when the gas extraction time is 120 d.
