漳村矿2601工作面瓦斯量预测及治理方法

Research the Zhangchun Mining 2601 working face methane Calculation and Treatment method

矿井瓦斯灾害是制约煤矿安全高效生产的难题,尤其在应用综采放顶煤的采煤工艺进行回采过程中,来源于采空区的瓦斯涌出量较大,直接导致上隅角的瓦斯浓度上升乃至超限,不仅影响煤矿的正常生产,甚至会引发重大安全事故。本文以潞安集团漳村煤矿2601工作面为研究对象,理论分析2601工作面瓦斯构成,预测了本采面的瓦斯涌出量,提出布置高抽巷来解决瓦斯问题。

Mine gas has always been a problem affecting the safe and efficient production of coal mine, especially forcoal mining technology with fully mechanized caving coal mining process, a large amount of gas emission from goaflead directly to gas consistency increase and overrun in the upper corner, that not only affects the coal mine normalproduction, and even lead to serious accidents. The 2601 working face in Zhangcun Coal Mine of Lu'an Group asthe research object. The 2601 working face gas source and constitute were analysised.To forecast the gas emissionquantity of the working face, and also analyze the necessity of the layout of the high pumping lane.
