摘要
针对矿井煤层透气性差的瓦斯地质条件并结合生产实践,研究了低透气性煤层瓦斯抽采的安全技术措施,确立了用高位钻孔进行瓦斯抽采,局部瓦斯涌出异常及工作面过钻场期间利用埋管配合高位钻孔进行抽采的综合治理方式;收到了显著的技术经济效果。
Aiming at the gas geology which has poor permeability of colliery as well as production practice, we researched the safety technical measures of coal seam gas extraction of low permeability in order to establish comprehensive governance mode which involves both gas extraction with high drilling and extraction with buried tube for high drilling when local gas gushed out abnormally and when working surface passed drill site and received significant technical and economic effect.
