摘 要:由于综放开采的特殊性,使综放开采工作面的瓦斯涌出强度大大增加,致使"分源法"中的某些"源"的计算公式及预测参数的取值范围适应性减小,预测精度降低。为了增加"分源法"的适应性,对阳泉五矿综放开采工作面瓦斯资料进行总结,对影响邻近层瓦斯涌出量预测参数进行分析,提出了适合综放开采工作面邻近层瓦斯涌出量预测方法,取得了较满意的拟合结果。Due to the particularity of mechanized caving mining, the gas emission intensity of mechanized caving mining face increased significantly, which resulted that the adaptability of value range decreased for calculation formulas and prediction parameters of some " sources" in "separate source method" , and the prediction accuracy reduced. In order to increase the adaptability of "separate source method" , the gas data of caving mining face in Yangquan No. 5 Coal Mine was summarized, and the effect parameters of gas emission prediction in the adjacent layer were analyzed. The gas emission prediction method suitable for the adjacent layer in caving mining face was proposed, and it achieved satisfactory fitting results.
