摘　　要：淮南矿业集团公司谢一矿望峰岗矿井是国家深井开采试验矿井,服务于-660m以下深部水平,为高瓦斯、强突出矿井。-817m轨道石门、皮带机石门揭C_(13)强突出煤层,采用"闭合环形巷道布置条带穿层抽采钻孔"实现了低瓦斯状态下安全揭开。Wangfenggang well of Xieyi mine of Huainan mining company is the experimental well of deep coal mining in China. This well is service to-660m level, and it has high gas outburst. Arranging strip cross-measure borehole in close-loop roadway was used to cut through C13 coal seam in-817m railway cross-cut and belt cross-cut, and it achieved cutting through the coal seam in low gas and safety.
