摘要
原相煤矿10200工作面02#煤层在回采过程中瓦斯涌出量大,针对瓦斯治理的难点是本煤层瓦斯涌出和邻近层瓦斯涌出相互叠加的问题,提出了采用本煤层预抽、下邻近层抽采、裂隙带抽采以及回风隅角抽采等方式进行瓦斯综合治理措施。实践表明:综合治理技术效果良好,解决了工作面回采期间瓦斯涌出量大的问题,保障了工作面的安全生产。
Aiming at the overlapping gas emission in coal bed and adjacent seam in No.02 coal seam at 10200 working face of Yuanxiang Colliery,the author proposes the comprehensive gas control measures of pre-drainage in coal bed,drainage in downward adjacent seams,fracture zone and return airway corner,which can solve the great gas emission with good control effect and guarantee the safety production at mining face.
