Based on the relations between supports and surrounding rock at the ends of top-coal caving fully-mechanized working face, this paper analyzes and designs the double-section-type top-coal caving hydraulic end-support with high-caving and. The core content of new end-support includes the low coal-raking system, which has the tilt scraper and the symmetric pair wheels and the high coal-caving system which has the unsymmetrical pair-open troughs. It has solved two key problems in the design process of end-support; one is that the end-support has enough space to place the rear conveyor of working face, the other is that the loose drop-coal on the floor can be carried into the high troughs of conveyor head and tail. This paper also analyzes the caving character of top-coal at the ends of working face and the feasibility of top-coal caving at the ends. Through the implementation of the project, it will improve the coal recovery significantly, produce good economic and social benefits, and have very important significance and wide application prospect through solving the difficult problem of top-coal caving at the ends of fully-mechanized working face.
