Nowadays, coal mine mechanical transportation mainly relies on belt conveyors to transport mined coal to the outside of the mine; belt conveyors are machines that use the stepless motion of belts to transport materials, with the advantages of long transportation distance, large transportation capacity, small working resistance, easy installation, low power consumption and less wear. Belt conveyors can automatically transport underground minerals to the ground, and can also transport minerals to automated warehouses for temporary storage.
