The invention relates to the technical field of draw shafts, in particular to a stope draw shaft discharge port bottom bearing device which comprises a wall and a vertical draw shaft, and bearing mechanisms are symmetrically arranged on the two sides of the vertical draw shaft; the bearing mechanism comprises a cavity formed in the side wall of the vertical draw shaft, and a middle shaft is connected to the side wall of the cavity through a bearing. The bearing mechanism further comprises buffering assemblies, the multiple sets of buffering assemblies are arranged outside the middle shaft, each buffering assembly comprises a side plate connected to the outer wall of the middle shaft, the side, away from the middle shaft, of each side plate is connected with multiple sets of buffering plates, and the buffering plates can drive the middle shaft to rotate in the same direction when being impacted by ore. According to the ore buffering device, the buffering assemblies are arranged, freely-falling ore can be buffe
