The invention relates to a dual-motor planetary gear transmission mine hoist and belongs to the technical field of mining equipment. The dual-motor planetary gear transmission mine hoist comprises a motor I, a speed reducer I, brakes, a reel, a speed reducer II, a motor II, planetary gears, an output shaft, a coupler, an input shaft, a bearing supporting seat, a supporting seat, a planetary gear supporting shaft, bolts, a supporting bearing I, an input gear ring I, brake pads, end cover plates, reinforcing ribs, a middle supporting plate, an input gear ring II and a supporting bearing II. The energy consumption of the whole hoist is effectively reduced. The working mode is more flexible, and the application range of the magnitudes of loads and the depths of mines is wider. The used space of a working site is reduced effectively, and therefore production and use cost is reduced. The reliability of the mine hoist is effectively improved, the security incident occurrence probability of the mine hoist in the working process is reduced, and a guarantee is provided for safe production. Faulty operation caused by visual and physical fatigue of workers can be prevented effectively.
