3401放顶煤工作面瓦斯防治技术研究

Research on gas prevention and control technology in 3401 caving face

本文以某放顶煤工作面为研究背景,确定瓦斯抽放方式及参数,并对工作面采空区、上、下隅角积聚的瓦斯进行防治,为类似工作面的安全回采提供了借鉴意义。

This paper takes a caving face as the research background, determine the gas drainage mode and parameters, the gas accumulation in the goaf, upper and lower corners of the working face is prevented and controlled, it provides a reference for the safe mining of similar working faces.
