摘　　要：随着采掘深度的延伸,一缘煤业由高瓦斯矿井升级为煤与瓦斯突出矿井。针对一缘煤业15#煤层的瓦斯赋存规律和采掘情况,制定了一套科学合理、切实可行的区域防突措施实施方案,该方案提出3个阶段的区域防突措施:第1阶段的区域防突措施主要采用顺层钻孔预抽煤巷条带、顺层钻孔预抽区段煤层瓦斯的方法;第2阶段为通过掘顶底板岩巷预抽煤层瓦斯,主要采用穿层钻孔预抽区段煤层瓦斯、穿层钻孔预抽回采区域煤层瓦斯的方法;第3阶段区域防突措施为开采保护层或在开采保护层前提下将预抽煤层瓦斯作为辅助手段结合使用。With the depth of mining, Yiyuan Mine is upgraded from high - gas coal mine to coal and gas outburst mine. According to gas occurrence regularity and the mining situation of 15^# coal seam of Yiyuan Mine, a scientific, reasonable and achievable design scheme for local integrated preventive measures against outburst is established. The design scheme is divided into three phases for local integrated preventive measures against outburst. The first phase is pre - drainage coal roadway stripes gas and section gas with the bed- ding boreholes ; the second phase is pre - drainage coal seam gas in the roof and floor roadway by pre - drainaging section gas and min- ing region gas ; the third phase is mining protective layer or the combination of mining protective layer and pre - drainage coal mine gas as a supplementary mean.
