It can reduce labor costs in the production process, simplify the operation process, improve labor productivity, reduce energy consumption, and improve intrinsic safety. In the process of ore mining, it is often encountered that the ore supply points are relatively scattered and far away from the original ore collection system. In this case, it is necessary to first study the drawings of each middle section and the current status of the project, and then determine the optimal location, and use the old project as much as possible to reduce the amount of work and reduce production costs, so as to achieve centralized lifting.

[0003] At present, when the centralized ore supply and lifting method is used to transport the ore, after the ore is poured into the mine, the ore falls irregularly and widely distributed in the tunnel at the mine exit. This requires a shovel or even manual labor to concentrate and assist in loading the ore, which wastes manpower, greatly reduces work efficiency, increases transportation costs, and is inconvenient to use.
