摘要
通过对义城煤矿 32 1 1回采工作面采空区瓦斯浓度分布的测定 ,初步查明了房柱式回采工作面采空区瓦斯浓度的分布规律 ,为今后采空区瓦斯抽放治理 ,防止采空区瓦斯事故的发生提供了科学的依据。
Through determining methane concentration distribution in goaf of 3211 coal face in Yicheng coal mine, methane concentration distribution law in goaf of room and pillar mining coal face is found out preliminarily, thus providing scientific basis for methane drainage and methane accidents prevention and control in goaf.
