Abstract

The invention relates to the technical field of open-pit mine side slope mining, in particular to an open-pit mine side slope mining system. The open-pit mine side slope mining system comprises a side slope continuous mining machine, a loading part, a belt conveying system and a movable reversed loader. The loading part is provided with a first connecting part and a second connecting part, and the first connecting part of the loading part is connected with the side slope continuous mining machine so that the side slope continuous mining machine can drive the loading part to move. The belt conveying system is provided with a first connecting part and a second connecting part, and the first connecting part of the belt conveying system is connected with the second connecting part of the loading part so that the loading part can drive the belt conveying system to move. The movable reversed loader is connected with the second connecting part of the belt conveying system so that the belt conveying system can drive the movable reversed loader to move, and the movable reversed loader is a crawler-type reversed loader or a wheel-type reversed loader. The system has the advantages of being simple in structure, low in investment cost and the like.

Description

technical field [0001] The invention relates to the technical field of side mining in open-pit mines, in particular to a side mining system in open-pit mines. Background technique [0002] Side coal recovery originated in the United States in the 1940s, and was initially recovered by auger drilling. Column side coal recovery in continuous mining machine room appeared in the 1970s and began to be widely used in the 1980s. Combined with half a century of industrial practice, side coal recovery has become an important open-pit mining method in countries such as the United States, Australia, Indonesia and India. Taking the United States as an example, coal production from side coal recovery accounts for 4% of the annual coal production in the United States. [0003] The invention patent with authorized notification number CN109931066B discloses a side mining system for open-pit mines. The side mining system for open-pit mines includes a side continuous coal mining machine, a m...
