摘　　要：为了解决厚煤层综放工作面开采过程中,顶煤冒放性差、回收率低等问题,通过分析北辛窑煤矿8405工作面放顶煤机理以及回采过程中煤炭损失原因,提出了8405工作面回采率提升的具体措施,并在现场应用,有效提高煤炭资源回收率。In order to solve the problem in the process of mining thick coal seam fully-mechanized sublevel caving mining working face,take the top-coal caving characteristics and low recovery rate of the problem,this article north of xin kiln coal mine 8405 working face as the research object,through the analysis of the caving mechanism in the process of the mining and coal loss in the main reason,puts forward some specific measures to face the recovery rate of ascension,and in the field application,effectively improve the coal recovery rate.
