| Abstract: | Aimed at the solution to the high refuse rate and the greater tendency of end surface caving etc, as in the case of roof-coal-caving of the thinner thick coal seams subjected to the full mechanized mining method in our country, the paper introduces the adoption of some practical technical measures, such as choosing proper bracket and reasonable techniques of roof-coal-caving increasing the regular circulating rate preventing top-coal from leaking between the bracket reducing end surface free of timbering space and performing betimes timbering of end surface, so as to realize the high-output and high-efficiency mining of roof-coal-caving in the thinner thick coal seams. |

| Keywords: | roof-coal-caving the thinner of thick coal seams refuse rate the control oftop-coal in end surface |
