摘要
介绍了大佛寺煤矿煤层赋存条件,提出了包括本煤层抽采、倾向卸压钻孔抽采、高抽巷抽采、上隅角抽采等瓦斯综合抽采技术。结果表明,瓦斯综合抽采技术可有效抽采本煤层和采空区瓦斯,消除瓦斯隐患,保证矿井的安全生产。对同类型煤矿的瓦斯治理工作具有指导意义。
Based on the analysis of the occurrence state of coal seams in Dafosi Coal Mine, the paper puts forward the comprehensive gas drainage technologies that including pre-drainage of coal seam, pressure relief hole drainage, high level tunnel drainage; upper cor- ner drainage. The results show that the comprehensive gas drainage technologies can pump the coal seam and goaf gas effectively, elim- inate the hidden danger of gas and ensure mine safety production. It has practical significance for the gas control of similar coal mine.
