潘一矿2371(1)下顺槽综掘工作面瓦斯涌出规律及影响因素

The Analysis of Gas Emission Laws and Influencing Factors Under 2371(1) Crossheading Fully-mechanized Excavation Face of Panyi Coal Mine

摘要: 通过对潘一矿2371(1)下顺槽综掘工作面瓦斯涌出量进行实测,对工作面瓦斯涌出来源及构成进行了分析。利用回归分析法,得出了综掘工作面煤壁及落煤瓦斯涌出规律,同时,找到了综掘工作面瓦斯涌出主要影响因素。

Abstract: Through the actual measurement of gas emission under 2731(1) fully-mechanized excavation face in Panyi coal mine,the sources and composition of gas emission in the working face were analyzed,then coal wall and gas emission law of falling coal under excavation face were obtained by regression analysis method.At the same time,the main influencing factors of gas emission in fully-mechanized excavation face were found.
