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 wells as a typical group of prominent coal seams mining. According to the conditions of coal seam and gas storage, starting from the development of well lane, production layout, mining sequence, face layout and so on, through years of production tests, we explored a set of “ Dimensional pumping ”regional gas management mode, from the design and mining sources to achieve high-gas outburst in the low-gas coal seam safe and efficient mining.
