摘　　要：采用煤层残余瓦斯含量为评判指标结合区域瓦斯抽采量对船景煤矿一采区东翼+640^+675 m的7~#、8-1~#、8-2~#煤层区域消突措施进行效果检验,并对煤层抽放进行评价及分析。结果表明:区域预抽煤层瓦斯防突措施有效,瓦斯预抽效果良好。Combines the method of seam residual gas content index and the quantity of pre-drainage gas to evaluate the effect of outburst prevention measures for the ＋640~＋675 m area of the esat of the first mining area in Chuanjing coal mine,and evaluats and analysis the effect of pre-drainage gas in Chuanjing coal mine. The result shows that the prevention measure of regional pre-drainage gas for coal seam outburst are effective,and the effect of pre-drainage gas is good.
