摘要
在分析近年来我国煤巷掘进工作面发生瓦斯灾害事故频发原因的基础上,对晋煤集团各煤矿企业目前所采用的几种常用掘进工作面瓦斯治理技术进行了对比考察,并分析了各个瓦斯治理技术在应用上存在的优缺点。最后提出了解决高瓦斯矿井掘进工作面掘进进度缓慢、瓦斯涌出量大导致瓦斯超限等问题的途径。
On the basis of analyzing the reasons of gas disasters and accidents happen ed frequently at heading face of our country＇s coal roadway in recent years.Contrast analysis of several gas treatment technologies commonly used in heading faces of coal mine enterprises in Jinmei group,the advantages and disadvantages of the various gas treatment technologies existing in application are analyzed.Finally the paper put forward new methods which could solve the problems of slow tunneling progress and gas transfinite caused by large gas emission at heading face in high gas mine.
