摘　　要：针对南阳坡矿综放工作面顶煤放出率较低问题,分别研究了不同放煤步距和放煤顺序时工作面顶煤运移规律及顶煤放出率,确定采用两刀一放配合间隔放煤的最优工艺。研究表明,间隔放煤较顺序放煤时工作面支架整体放煤量较高,优化后提高顶煤放出率。In view of the low top coal caving rate in Nanyangpo Coal Mine,the paper studies the top coal movement rule and top coal caving rate in different caving steps and sequences,and determines the optimal technology of two knives and one caving with interval caving.The results show that the amount of coal released from the support of the working face is higher than that of the sequential coal release,and the top coal release rate is increased after optimization.
