摘　　要：厚煤层综合放顶煤开采具有很大优越性,同时也存在综放工作面回收率低的突出问题。结合招贤矿业1307综放首采工作面的开采,通过文献查阅、数据分析和数值模拟等方法,分析影响综放工作面资源回收率的主要因素,提出了对策并现场应用得到印证,对综放工作面生产具有较好的推广价值。Comprehensive caving mining in thick coal seam has great advantages, but there are also outstanding problems of low recovery rate in fully-mechanized caving face. Combining with the mining of 1307 fully-mechanized caving face in Zhaoxian Mining Industry, the main factors affecting the resource recovery rate of fully-mechanized caving face were analyzed by means of literature review, data analysis and numerical simulation. The countermeasures were put forward and verified by field application, which has good popularization value for the production of fully-mechanized caving face.
