| description | The invention discloses a safety high-efficiency exploitation technology for a sharply inclined ore body. A mining technology comprises the steps of: arranging mining entrances in a rhombus shape, andcompleting rock drilling, blasting and ore removal in the mining entrances; in the blasting process, by controlling blasting parameters of mining blast holes, reserving triangular integrated separation ore plates at semi-surrounded shaped edge parts of the mining entrances of an upper segment stope and on the boundary of the upper segment stope; in the process of mining ores, recovering the separation ore plates at an interval of two steps; and in the initial stage of current step ore drawing, reserving and not recovering the separation ore plates at first two step positions, and until the current step ore drawing is ended, recovering the reserved separation ore plates in the current step due to self-falling or forced caving of the separation ore plates. By adopting the safety high-efficiency exploitation technol |
