Abstract In order to realize safe recovery mining of 1614 large and complex inclined angle working face in Xiandewang Mine, based on the mining working face features, support stability and fan-shaped mining technology was studied. The result showed that measures that improving the initial support force, increasing friction coefficient between support and top and bottom plate and the roof control of sector condition and old roadway, finally realized the safe recovery mining of 1614 working face, providing reference for working face under similar condition.
