摘要
为解决高瓦斯煤层群井下安全生产的问题,以山西朱家店矿4101工作面为例,分析了工作面煤层的瓦斯来源,根据抽采钻孔施工的影响因素,对4101工作面提出了本煤层瓦斯抽采、邻近层瓦斯抽采和采空区瓦斯抽采的瓦斯综合抽采技术,实现了采前预抽、边采边抽和采后采空区抽放的综合抽放方法,为煤层群瓦斯治理提供了比较有效的技术途径。
In order to solve the safety mining problem in high-gassy coal seam group,taking the 4101 working face of Zhujiadian Coal Mine in Shanxi for example,the gas source of working face was analyzed,and according to influencing factors of extraction drill construction,a comprehensive gas extraction technology was put forward for the 4101 working face,including gas extraction in mining coal bed,gas extraction in adjacent seam and gas extraction in goaf,which realized pre-extraction before mining,gas extraction while mining and gas extraction in goaf after mining,that provided relatively effective technical method for gas control in coal seam group.
