摘　　要：区域防突措施是指在突出煤层进行采掘前,对突出煤层较大范围采取的防突措施,井下预抽煤层瓦斯是一种非常重要的区域防突措施。本文根据A煤矿15号煤煤层赋存、瓦斯地质、采掘部署等情况,提出了五种井下预抽煤层瓦斯方案,通过对比各自优缺点选定了两种方案。Regional outburst prevention measures refer to adopt large-scaled outburst prevent measures to the outburst coal seam before it is developed.Pre-drainage of coal mine methane is an important measure for regional outburst prevention.The paper proposed five options of coal mine methane pre-drainage according to the condition of the coal seam occurrence,the gas geology and the development plan of No.15 coal seam in A Coal Mine,and selects two options through comparison of advantages and disadvantages.
