戊—21191综采工作面采空区及下隅角瓦斯分布规律研究

Study on methane distribution law of goaf and down- corner angle in Wu-21191 fully-mechanized coal face

本文采用数值模拟和实际测定两种方式分析研究了戊— 2 1 1 91综采工作面采空区及下隅角瓦斯浓度分布规律 ,为该工作面的瓦斯综合治理提供了理论依据。

in this paper, methane distribution law of in goaf and down-corner angle of Wu-21191 fully-mechanized coal faces is analyzed and studied by using mathematical simulation and actually measurement, thus providing theory base for comprehensive controlling methane in this coal face.
