平煤六矿戊8煤层综采面采空区瓦斯涌出规律分析

Analysis of rule of gas emission in goaf of fully mechanized coal mining face of Wu No.8 coal seam in Pingmei No.6 coal mine

通过对戊8-22310工作面通风瓦斯资料及数据的分析,应用工作面、采空区瓦斯涌出相关理论和统计分析方法,分析了该工作面采空区瓦斯涌出规律,探讨了采空区瓦斯涌出量与日产量、采空区长度和顶板周期来压的关系.分析结果为煤矿采空区瓦斯管理提供一定的参考依据.

Based on the analysis of ventilation gas data and data in Wu8-22310 working face, the gas emission law in goaf was analyzed by applying the relevant theory and using the statistical analysis method of gas emission in working face and goaf.The relationship among gas emission amount in goaf and daily output, length of goaf and cyclic weighting of roof was discussed. The analytical results provide a reference for gas management in goaf of coal mines.
