摘　　要：以凤凰煤矿1402采煤工作面为工程应用背景,运用岩层移动理论,研究了采煤工作面大流量、高浓度卸压瓦斯的运移路径和富集区域;通过选择合理的瓦斯抽采方法,优化瓦斯抽采关键参数,提高了采煤工作面瓦斯抽采率和抽采浓度,实现了采煤工作面瓦斯抽采达标;降低了采煤工作面瓦斯涌出量,消除了采煤工作面瓦斯积聚现象,保证了采煤工作面安全高效生产。Based on Feng Huang Coalmine 1402 double long wall coalface,vertical three zones of stratum movement theory was applied in long wall coalface,migration paths of pressure-relieved gas and abundant gas region was discussed.By means of choice of reasonable drainage methods and optimal drainage parameters,the gas drainage efficiency and drainage concentration has been improved,standard effect of gas drainage in long wall coalface was achieved.Gas emission arising from coalface has been reduced,gas accumulation phenomenon has been eliminated,safe and efficient production has been realized.
