摘　　要：以平煤十矿戊_(9-10)21210工作面为工程背景,提出高瓦斯煤层短壁消突技术。在回风平巷内向区段运输平巷位置施工100 m水力压裂深孔和本煤层抽放钻孔,钻孔有效消突范围覆盖区段运输平巷及下帮15 m以上。使用数值模拟软件模拟得出抽采孔的合理间距为1.5 m。此短壁瓦斯消突技术的应用既缓解了十矿釆面的接替压力又有利于区段运输平巷的安全掘进,实现了高瓦斯煤层的安全开采。Based on the engineering background of 21210 face in No.10 mine of Pingmei, so puts forward a short wall at high gas seam eliminating outburst technology. From wind tunnel to the machine tunnel construction 100 m hydraulic fracturing deep and the coal seam drainage hole, drilling under effective outburst elimination range covering machine lane and more than 15 m; using numerical simulation software obtained drainage holes reasonable distance is 1.5 m. The short wall of the gas outburst elimination technique not only alleviate the pressure to succeed in No.10 mine of Pingmei also conducive machine tunnel safe tunneling, achieve a safe mining in high gassy coal seam.
