Joint development of shaft-belt conveyor inclined shaft in Dong'aojipu copper mine

South Africa's Eastern Aoji Pu (East O'okeip) is a copper mine shaft - belt conveyor jointly developing typical examples. The upper part of the mine was developed with a shaft, and the deep part was developed with a belt conveyor inclined shaft. This kind of development is mainly due to the lack of deep minerals. The deep shaft is not only short in length, but also has a long stone gate and a large amount of engineering. Therefore, a linear belt conveyor and trackless self-propelled equipment are drilled on top of the shaft bottom bucket bucket. The shared ramps open up deep ore bodies. The slope of the slope is 25%, the length is 300m, and the section width × height is 4.9 × 2.7m. Used to transport ore. The daily production capacity of the mine is 1000t. The mine development system is shown in Figure 1.
