Description

Technical Field

[0001] The present application relates to the technical field of conveying equipment, for example, to a mining conveying system. Background Art

[0002] Mineral transportation is a very important and indispensable link in the mining production process. At present, the main processes for material transportation in mines in my country are as follows: The horizontal tunnel transportation scenario mainly adopts a combination of mine car transportation and belt transportation. In the inclined shaft hoisting scenario, for the case where the inclined shaft inclination angle is less than or equal to 27°, a winch is used to pull a string car, for the case where the inclined shaft inclination angle is less than or equal to 17°, a belt transportation is used, and for the case where the inclined shaft inclination angle is greater than 17° and less than or equal to 24°, a large-angle belt transportation is used. In the vertical shaft hoisting scenario, a winch is mainly used to pull a skip or cage. The open-pit mine slope mining and transportation scenario is similar to horizontal tunnel transportation, and rigid belts are mostly used with mine car transportation.

[0003] Among the above transportation processes, mine cars, winches and cages are all reciprocating non-continuous transportation equipment with low transportation efficiency. Although belt conveyors can transport continuously, they cannot turn and transport in processes such as connecting tunnels, cutting holes, strip mining, open-pit mining, and slope mining, which limits their application scenarios.
