屯兰矿回采工作面下邻近层瓦斯治理试验分析

Test Analysis on Gas Control of Mining Face Next Near Coal Bed in Tunlan Coal Mine

根据回采工作面回采时底板瓦斯对工作面的影响,结合现主采煤层与下邻近层层间距,提出回采工作面下邻近层瓦斯治理试验技术,通过对下邻近层瓦斯治理技术应用效果分析,得出了下邻近层瓦斯治理技术在高瓦斯工作面的应用前景。

According to the influence of the floor gas to the face when the coal mining,combines with interlayer distance of the main mining coal bed and next near coal bed,puts forward gas control test technology made of next near coal bed in the mining face,through analyzing the application effect of gas control technology to the next near coal bed,obtains the application prospect of the next near coal bed gas control technology in the high gas mining face.
