摘要: 为解决高瓦斯中近距离煤层群安全开采问题,针对阳泉大贤煤矿9号与15号煤层开采条件及瓦斯赋存特征,根据矿井瓦斯涌出量构成关系,对两层煤同时开采瓦斯抽采可行性进行分析,设计了瓦斯抽采方案,并研究确定了工作面瓦斯抽采巷道布置、抽采钻孔技术参数及采空区瓦斯抽采参数,可为类似低渗透性煤层瓦斯的治理提供很好的借鉴。

Abstract: The paper make a design and application for the two level mining at the same time with Yangquan No.9 and No.15 coal seam conditions and gas characteristics. And according to the characteristics of working face, confirm the gas drainage roadway layout, drilling technical parameters and goaf gas drainage scheme. By practical application, No.9 coal seam gas drainage achieved the rate of 42%, No.15 coal seam gas drainage achieved the rate of 76.5%, completely meet the requirements of the working face gas drainage. The project has obtained the satisfactory result of extraction.
