Abstract: In order to overcome the difficulty in vulcanization of the joints of belt of the belt conveyor used in the main blind inclined shaft, a belt vulcanizer working platform is developed, The platform works in combination with a set of upper and lower vulcanizing plates and its operation is mechanized for the use of movable upper plate. The use of the platform has led to higher belt vulcanization efficiency and greatly reduced labor intensity. This may serve as a reference for tackling similar problems.
