The invention provides a solid filling coal-mining vertical feeding mine multi-grade generating system, and belongs to a system for generation by employing fed solid filing materials. The bottom of a vertical feeding system is provided with 4-6 sets of driving wheels, each set of driving wheel, a matched conic gear commutation driver, a gear box, and a generator form a first-grade power generation sub-system, the driving wheels rotate by collision of the filling materials, the mechanical energy is converted to electric energy, and first power generation is realized; furthermore, the positions corresponding to buffer springs of a conical buffer are provided with permanent magnets aligned with the middle portions of inductance coils to form a second-grade power generation sub-system, the conical buffer moves up and down in the colliding process of the filling materials, the permanent magnets are driven to perform interaction movement with the corresponding inductance coils to generate current, and second power generation of the solid filling coal-mining vertical feeding system is realized. According to the generating system, the kinetic energy generated by feeding in solid filling coal-mining is fully utilized, a lot of clean energies are provided, energy waste is reduced, and normal production of mines is not affected.
