【Abstract】 In the mining of medium and thick seams, the fully mechanized top coal caving mining method has great application advantages, which can give full play to the production efficiency, thus greatly improving the mining efficiency and economic benefits. In the application of top-coal caving mining, the recovery rate of working face is a key problem, how to improve the recovery rate has always been a problem that coal mining enterprises attach great importance to. Based on the analysis of fully mechanized top-coal caving mining technology, the measures to improve the recovery rate of fully mechanized top-coal caving face are discussed in order to promote the development of fully mechanized top-coal caving technology and realize high-yield and high-efficiency mining of fully mechanized top-coal caving.更多还原
