刘庄煤矿工作面上隅角瓦斯治理技术应用

Application of Gas Treatment Technology in Upper Corner of Liuzhuang Coal Mine

为了解决刘庄特厚煤层综放工作面上隅角瓦斯频繁超限问题,在不同开采阶段采用了"U+I形通风方式+临近巷道抽放法对采空区瓦斯半封闭抽放+多种抽放方式相结合"的瓦斯综合治理方法,从实际应用效果来说可有效降低该工作面瓦斯超限次数,提高了工作面瓦斯抽采率,从根本上解决了该工作面瓦斯超限问题,同时为刘庄矿井在下一工作面瓦斯治理提供了良好的示范,为该矿井的安全高效生产提供了保障。

In order to solve the Liuzhuang specially thick coal seam upper comer gas overrun problem frequently at the fully-mechanized coal mining face,mining in the different stage of the ＂U ＋ I ＋ ventilation way near form of semi-closed goal drainage roadway drainage method ＋multiple drainage methods combining＂ the gas comprehensive control method, from the practical application effect,can effectively reduce the number of working face gas overrun, improves the working face gas extraction rate, fundamentally solved the problems of the working face gas overrun,at the same time as the Liuzhuang mine next working face gas control provides a good demonstration,efficient for the mine safety production to improve the security.
