摘要
针对松软低透气性突出煤层瓦斯治理的技术难题,首山一矿通过探索运用"一面七巷"布置方式,采用3条低位抽巷掩护3条煤巷掘进、3条煤巷掩护采面回采、1条高抽巷治理采空区瓦斯,使掘进工作面安全掘进,回采工作面安全回采,上隅角瓦斯得到有效防治。
For technical problems of low permeability outburst coal seam of low permeability,＂ seven tunnel of one mining face＂ arrange- ment mode was applied in Shoushan No. 1 Mine for test. Three low tunnels were used to shield the driving of three coal roadways, and three coal roadways play the roles for shielding the coal winning of working face, one high-level gas drainage roadway was used to control the gas in gob. The usage of this mode has ensured the safe driving of working face and smooth coal wining of working face, the gas in upper corner was also controlled effectively.
