[0023] In the above embodiments provided by this utility model, the application of the latest technology of steep-angle belt conveyors can greatly reduce mine infrastructure investment; shorten infrastructure construction time and transportation distance in deep mining of metal open-pit mines, saving mine transportation costs; at the same time, the layout of steep-angle belt conveyors can shorten the route length, effectively avoid slopes with adverse geological conditions, and improve the safety and reliability of the system.

[0024] Furthermore, due to the large angle of the inclined belt conveyor 7, materials may slide or roll backward due to gravity, leading to decreased transport efficiency, or even blockage or overflow. This utility model further provides an embodiment in which the inclined belt conveyor 7 is a clamping conveyor. This clamping conveyor includes a carrying belt and a cover belt. The carrying belt is responsible for carrying and transporting the ore, while the cover belt is responsible for covering the ore. The pressure is provided by the gravity of the cover belt or external pressure acting on the back of the cover belt. The clamping conveyor can prevent material slippage. In this clamping conveyor, the carrying belt and cover belt are coupled and operate synchronously. Simultaneously, a tensioning device station 8 for the inclined belt conveyor is also provided between the second transfer station 3 and the third transfer station 4.
