腾晖煤矿低位钻孔抽放综放面采空区瓦斯探究

Study on gob gas drainage technology of fully mechanized caving face with low level boreholes in Tenghui Coal Mine

针对腾晖煤矿综采放顶煤工作面采空区瓦斯量大给安全生产带来的隐患,提出采用低位钻孔对采空区瓦斯进行抽放的设计方案。通过实践,取得了良好的抽放效果,解决了腾晖煤矿工作面采空区瓦斯问题,为相似条件下的煤矿采空区瓦斯抽采提供了经验。

According to the risk of gob gas emission of fully mechanized caving face to mine safety production in Tenghui Coal Mine,gob gas drainage plan by low level boreholes was designed. The practice shows that the gas drainage technology has achieved good effect and solved gas problem. The research can provides reference for gob gas drainage of coal mine with similar conditions.
