摘　　要：从顶煤的冒放性 ,顶煤的采出率及影响因素等方面进行论证 ,提出提高顶煤采出率的主要途径 :合理选择架型 ,合理选择工作面推进方向 ,优化放顶煤参数 ,并通过对顶煤运动规律 ,顶煤冒放性规律的研究 ,确定合理的放顶煤步距 ,合理的采放高度比和合理的放煤工艺 。This paper describes from 冒放性 mining ratio and influence factor of top-coal,main way of improving mining ratio of top-coal is raised:shelf model and driving direction of workface is selected rationally.Caving parameter is optimized and distance high and craft of caving is defined rationally through study moving rule and 冒放性 rule of top-coal,actual mining will be improved.

关 键 词：顶煤采出率 顶煤冒放性 放煤参数 综合机械化 支架 放煤参数 煤层裂隙
