Abstract
A microwave-mechanical fluidization mining system and a mining method for metal mines. The microwave-mechanical fluidization mining system comprises a microwave pre-splitting mechanical mining system, a microwave separation system, a high-power microwave focused melting system and a goaf, wherein ore-waste rock mixtures mined by the microwave pre-splitting mechanical mining system are transported to the microwave separation system through a conveyor and an elevator on the microwave pre-splitting mechanical mining system, separated ores are transported to the high-power microwave focused melting system, and separated waste rocks are transported through a conveyor to the goaf for filling. Microwave pre-splitting mechanical mining is adopted instead of a traditional blasting mining method to increase an excavation speed and avoid the influence of blasting on the stability of surrounding rocks.
