The invention relates to the technical field of coal mining, in particular to a coal mine underground exploiting construction gangue continuous discharging system which comprises a belt conveyor located on a tunneling working face, a gangue sliding small well is formed in the ground of the tunneling working face, a shaft is fixedly arranged in the gangue sliding small well, and the bottom of the shaft is connected with a sliding nozzle with an opening and closing device. A transportation rail is arranged on the ground of the lower-layer rail transportation roadway, and a transportation mine car is arranged on the transportation rail; when the gangue is discharged, the gangue is carried to the position above the gangue sliding small well through the belt conveyor and falls into the gangue sliding small well to be temporarily stored, the gangue is loaded into the transportation mine car arranged in the lower-layer rail transportation roadway by controlling the opening and closing device arranged at the discharg
