| 摘 要： | 放顶煤回采工艺参数的合理选取，对顶煤的有效回收起着重要的作用。采用实验室相似模拟的方法，从采放比、放煤步距等决定顶煤垮落空间的因素和顶煤块度等方面分析了其对顶煤垮落的影响，为特厚煤层综放开采顶煤回收率的提高提供理论依据。

| Abstract: | The rational selection of the technique parameters playeo an important role in the effective recovery of top coal. With the similar simulation method in lab, the paper analyzed the mining and caving rate, caving distance between steps and other affected to the top coal caving space as well as the iump coal from top coal influenced to top coal caving. The analysis provided the theoretical bases to improve the coal recovery rate of the fully mechanized longwall top Coal caving and mining in special thick seam. |
