顶煤回收率偏低一直是困扰综放开采的一个核心问题，提高综放工作面顶煤回收率对实现综放开采高产高效具有重大意义。本文结合胡家河煤矿401102综放工作面的实际情况，对顶煤破碎机理和冒放性进行了研究，并分析了不同移架方式对顶煤回收率的影响。
頂煤迴收率偏低一直是睏擾綜放開採的一箇覈心問題，提高綜放工作麵頂煤迴收率對實現綜放開採高產高效具有重大意義。本文結閤鬍傢河煤礦401102綜放工作麵的實際情況，對頂煤破碎機理和冒放性進行瞭研究，併分析瞭不同移架方式對頂煤迴收率的影響。

The lower recovery ratio of top-coal in fully mechanized caving face is a main problem , and improving the recov-ery ratio of top-coal has great significance to the high production and high efficiency of fully mechanized caving mining . Based on actual practice of №401102 fully mechanized caving face in Hujiahe Mine , the crushing mechanism and cavability of top-coal was researched , and the influence of different way of moving supports to the recovery ratio of top -coal is analyzed too.
