Abstract: According to the factors of frequently occurring equipment faults,the high failure rate and other status existed in fully-mecha-nized coal mining process of st eep inclined seam in Lyushuidong Mine,as well as appling fully-mechanized coal mining technique,app-ling matched equipment and other factors,the summarized and anal yzed the phenomenon and problems existed in the production site,stressed the analysis on an evolution of the steep inclined fully-mechanized coal mining technique and th e applied features of hydraulicpowered support,face- end powered support and other coal mining face equipments,and introduced the key technology of completeequipmen t for the fully-mechanized automatic coal mining face in the steep inclined seam. According to the practical requirements ofresearch and development conducted by Guang neng Group Corporation Limited in the fully-mechanized coal mining equipment for steepinclined seam,the paper provided the idea and orientation to solve the problems of the fully-mechanized coal mining in steep inclinedseam.
