摘　　要：为保证安全开采高瓦斯工作面,在分析W3305工作面地质及瓦斯涌出量的基础上,工作面设计采用掘进期间掘进工作面左右帮部钻场边掘边抽放、回采期间抽放本煤层瓦斯、工作面顶板裂隙带钻孔、高位抽放巷以及采空区埋管抽放的方法综合治理工作面瓦斯,回采期间工作面瓦斯抽放率为66.08%,实现了工作面安全回采。In order to ensure the safe mining of high gas working face,based on the analysis of geology and gas emission of W3305 working face,the design of working face adopts the methods of gas drainage while driving at left and right sides of working face during driving,gas drainage of coal seam during mining period,drilling holes in roof fracture zone of working face,high-level drainage roadway and buried pipe drainage in goaf.During the mining period,the gas drainage rate of the working face was 66.08%,which realized the safe mining of the working face.
