摘　　要：通过对寺河煤矿2301s工作面北翼胶带巷综掘工作面瓦斯涌出参数的测试及涌出特征的分析,得出2301s工作面北翼胶带巷煤壁落煤瓦斯解吸强度与暴露时间的关系近似为双曲线关系,建立了掘进工作面单位时间内煤壁瓦斯涌出量数学模型,为2301s工作面及寺河煤矿瓦斯涌出规律的研究提供了依据。Through gas emission parameters testing and characteristics analyzing of North wing belt roadway fully mechanized excavation face in Sihe coal mine 2301s working face,it is obtained that the relationship between gas desorption intensity of fallen coal and exposure time in North wing belt roadway of 2301s working face is approximately hyperbolic.Mathematical model of coal wall gas emission per in unit time at heading face is estabilished,which provides a basis for studying gas emission law of the 2301s face in Sihe coal mine
