淮南矿区突出煤层群开采瓦斯治理模式

Gas Control Mode of Outburst Coal Seams in Huainan Coal Mining Area

望峰岗井为典型的突出煤层群开采矿井。根据煤层及瓦斯赋存条件,从井巷开拓、生产布局、开采顺序、工作面布置等出发,通过多年的生产试验,探索出一套"分组开采卸压层、设置顶底板抽采巷、立体抽采"的区域瓦斯治理模式,从设计、开采源头实现了高瓦斯突出煤层在低瓦斯状态下安全高效回采。

Wangfenggang mine is a typical coal mine of mining outburst coal seams. According to the coal seams and gas occurrence conditions, from the tunnel development, production arrangement,mining sequence, face layout and so on, this coal mine has summed up a set regional gas control mode of ＂respectively mining protective layer, tunnelling roof or floor roadway, three-dimensional gas drainage＂ through many years of mining practice, outburst coal seams from the beginning of design and mining to achieve safe and efficient mining in the low gas state.
