The invention provides a mining self-discharging hopper. The hopper comprises a backboard which is an iron board with the thickness of 3mm, the lower portion of the backboard is in arc connection with a baseboard, the middle portion of the baseboard is fixedly provided with a lower ear plate, the middle of the lower ear plate is bored, the lower portion of the backboard is in seamless connection with a lower side plate, the upper portion of the backboard is in seamless connection with an upper side plate, the upper side plate is fixedly provided with a guard board, the guard board is fixedly provided with an upper ear plate, the upper ear plate is fixedly arranged on a reinforcing plate, the reinforcing plate is an iron plate with a certain angle, and is laminated to and fixedly arranged on the upper side plate, the front of the hopper is sequentially provided with a lower front plate, a middle front plate and a discharging port, the top of the hopper is provided with a feeding port, and the lower front plate is in arc connection with the baseboard. The mining self-discharging hopper ingeniously uses the gravity center principle, so ores in the hopper can be discharged from the discharging port when the hole axes of the upper ear plate and the lower ear plate are in a same horizontal plane, thereby the energy consumption of a crane is reduced, the processing technology is simple, and the making cost is low.
