大采高综采工作面瓦斯综合治理实践

Practice of Gas Comprehensive Control at Large Mining Height Fully Mechanized Coal Face

对阳煤集团一矿S8310大采高综采工作面瓦斯来源进行了分析,对瓦斯涌出量进行了预测,根据预测结果提出了瓦斯抽采为主、风排瓦斯为辅的综合治理瓦斯方案。通过采取本煤层采前预抽、边采边抽、高抽巷本煤层采空区及邻近层瓦斯抽采等综合瓦斯抽采措施,实现了工作面的正常循环和高产高效,为阳泉矿区大采高的工艺的推广积累了瓦斯治理经验。

Based on the analysis of gas resources and the prediction of gas emission in $8310 large mining height fullymechanized coal face, No. 1 Colliery, Yangquan Coal Industry Group Co., Ltd., the paper put forward a comprehensive gas controlscheme of mainly by gas extraction and subordinately by exhaust gas, which achieved normal cycle and high yield and highefficiency of working face and accumulated gas control experience for the technology promotion of large mining height inYangquan mining area.
