摘　　要：对于放顶煤工作面,合理预测顶煤冒放性是工作面高效生产的基础。本文利用某矿极近距离煤层合层综放开采为工程背景,对含有厚夹矸煤层的顶煤冒放性进行综合预测,并依据研究结果,提出了改善顶煤冒放性的措施,有效保障了工作面的正常生产。For the coal working face,it is the basis for efficient production of the working face.This paper,by using extremely close distance coal seam in a mine as the engineering background,of full-mechanized caving mining thick coal seam with thick dirt band comprehensive prediction of top-coal,according to the results of the study,put forward the measures to boost the top-coal risk put sex,effectively guarantee the normal production of working face.
