摘　　要：为解决某矿主采煤层瓦斯含量高、工作面瓦斯浓度高等制约矿井安全高效生产的问题,根据煤层瓦斯参数及赋存情况,采用回采巷道边掘边抽及顺层钻孔预抽回采区域煤层瓦斯措施,并对回采工作面瓦斯预抽效果及评价指标进行分析。In order to slove the problem of high gas content of main mining seam and high gas concentration of working face which has threatened the production of safety and high efficiency of the certain mine,based on gas parameters and gas storage regulation of mining seam, taking measures of draining while driving and gas pre-drainage along coal seams,analyzing the effect of gas pre-drainage before mining and evaluation index.

关 键 词：煤层预抽 边采边抽 边掘边抽 效果评价
