摘　　要：断层构造的特殊性决定了其本身可能赋存大量瓦斯,联系断层导致的瓦斯突出问题给矿井正常生产带来巨大的安全隐患。在矿山压力理论的基础上,探讨联系断层瓦斯通道的形成机理及瓦斯渗透规律,对通道注浆及瓦斯抽放的时机进行分析,可为类似瓦斯突出矿井提供可借鉴的预防、处理措施。The structure of fault determines the possible occurrence of a large number of gas, the gas outburst caused by contact faults bring a security risk to normal production. On the basis of the mine pressure theory, to explore the formation mechanism of gas channel around contact faults and the law of gas permeability, at the same time make the timing analysis for grouting and gas drainage. It can provide reference on prevention and treatment measures for similar mines.
