[0002] The temperature in most areas of the north is relatively low in winter. The water dripping from the inner wall of the shaft, the moisture condensed on the derrick, and the water brought into the shaft from the underground during excavation operations will condense into ice cubes on the inner wall of the shaft and the derrick under the action of low-temperature air. Ice cubes on the shaft wall can easily cause the cage to run, and falling ice cubes can easily cause damage to personnel and equipment. Although a heating device can be set on the shaft wall to prevent freezing in the prior art, the heating device covers a large area of the shaft wall of the mine, which not only increases the equipment cost, but also makes construction difficult.
