针对新疆乌东煤矿南北采区瓦斯赋存规律差异明显的现象,结合矿区构造特征,对乌东煤矿瓦斯赋存主控构造特征进行了分析.通过地质构造演化分析、井下瓦斯参数测定、井下采煤工作面瓦斯涌出量数据统计,确定了碗窑沟逆冲断层及其反冲断层F3-4、八道弯向斜为乌东煤矿的瓦斯赋存主控构造.结果表明:主控构造将矿区分为3个瓦斯地质单元,七道弯背斜低瓦斯区工作面相对瓦斯涌出量为0.65 m3/t,八道弯向斜北翼高瓦斯区工作面相对瓦斯涌出量为9.59 m3/t,八道弯向斜南翼低瓦斯区工作面相对瓦斯涌出量为1.41 m3/t.乌东煤矿瓦斯赋存分带、瓦斯灾害危险性分布受主控构造控制明显.%In view of the obvious difference in gas occurrence between north and south of Wudong Coal Mine in Xinjiang, combined with the structural features of the mining area, this paper analyzed the characteristics of main control structure of gas occurrence in Wudong Coal Mine. Through the analysis of geological structure evolution, the measurement of underground gas parameters and the statistics of gas emission data from underground coal working face. The main control structure of gas occurrence in Wudong Coal Mine was determined, which was Wanyaogou thrust fault and its recoil fault F3-4and Badaowan syncline. The results showed that the main control structure divides the mining area into three gas geological units, relative gas emission amount of the working face in low gas area is 0.65 m3/t in Qidaowan anticline, relative gas emission amount of the working face in high gas area is 9.59 m3/t in Badaowan syncline north wing, relative gas emission amount of the working face in low gas area is 1.41 m3/t in Badaowan syncline southwing. The distribution of gas occurrence and gas disaster was obviously controlled by the main control structure in Wudong Coal Mine.
