[0002] Belt transportation is often applied to various scenarios that require a large amount of continuous material transportation. It plays an important role in the fields of industrial production and logistics. In resource extraction sites such as mines and coal mines, belt transportation is used to transport raw materials such as ores and coals, quickly transferring the mined materials from the mining face to the processing or storage locations.
