摘　　要：分源预测法是我国目前应用最广泛的瓦斯涌出量预测方法,但不适用于应用综放工作面的矿井。由于综放工作面矿井瓦斯涌出来源和涌出强度与一般综采工作面有所不同,矿井瓦斯涌出量差别较大。基于分源预测法,提出了综放工作面的瓦斯涌出量预测方法,应用于山西大远煤业综放工作面瓦斯涌出量预测,并与实际观测结果对比。结果表明:改进的综放工作面瓦斯涌出量预测方法符合综放工作面的实际情况,对综放开采工作面的瓦斯涌出量预测具有一定意义。Sub source prediction method is a gas emission forecasting method which has been widely used in our country, but it is unsuitable to the fully mechanized top coal caving face of mine. Because the gas emission sources and intensity of fully mechanized top coal caving are different with general fully mechanized working face, and this make a great difference on mine gas emission, base on the sub source prediction, a method to predict gas emission in fully mechanized top coal caving working face was put forward. The method was used for gas emission prediction in fully mechanized top coal caving face of Shanxi Dayuan coal industry Co. Ltd, and the results were compared with the practically observed results, It showed that the improved prediction method of gas emission in fully mechanized top coal caving face fitted well with the actual situation, which is meaningful for gas emission prediction in fully mechanized top coal caving face.
