摘　　要：确定合理的瓦斯巷设计参数是确保采空区瓦斯抽采效果、防止工作面瓦斯超限的关键。对比分析大兴矿10个工作面顶板瓦斯巷抽采效果,从工作面采高、煤层倾角以及顶板岩性等方面进行瓦斯抽采影响因素分析,为大兴矿后续工作面顶板瓦斯巷参数设计提供借鉴。Determining the reasonable design parameters of gas roadway is the key to ensure the gas extraction effect in mined-out area and prevent gas overlun in working face. Contrastively analyzing roof gas extraction effect in 10 working faces of Daxing Mine, from the mining height of working face, coal, seam inclination and lithological characters of roof and other aspects, we analyze the influencing factors of gas extraction, which provides reference for the follow-up work of parameters design of roof gas roadway in Daxing Mine.
