摘　　要：根据综放工作面采煤特点,结合义络煤业的实际生产情况,利用分源预测法,将三区段33060综放工作面的瓦斯涌出源头细分为工作面煤壁瓦斯涌出、工作面落煤瓦斯涌出、采空区瓦斯涌出以及邻近层瓦斯涌出4部分。然后综合考虑这几种瓦斯涌出的影响因素,详细分析瓦斯涌出规律,得出瓦斯涌出量分源预测的数学模型,以更好地指导矿井瓦斯抽放,实现安全高效生产。Based on the coal mining characteristics of the fully-mechanized top coal caving face and the actual production situation of Yiluo Coal Industry Co.,Ltd.,the gas emission sources of 33060 fully-mechanized top coal caving face in No.3 section were subdivided into four parts:coal wall gas emission,coal caving gas emission,goaf gas emission gas emission from adjacent coal seams using the source separation prediction method.Then,taking into account the influencing factors of these types of gas emissions,a detailed analysis of the gas emission law was conducted,and a mathematical model for predicting the gas emission amount by source was obtained to better guide the gas drainage in the mine and achieve safe and efficient production.
