Description

[0002] Iron ore is an important raw material for steel production enterprises. Natural ore is gradually separated from iron through crushing, grinding, magnetic separation, flotation, gravity separation and other procedures. Iron ore is a mineral aggregate containing iron or iron compounds that can be economically utilized. At present, ore mining mostly uses mechanical equipment for mining operations. The tunnel boring machines used under the existing technology are prone to wear and tear during operation, causing the drill bits to be scrapped. The drill bits are mostly integrated in design, which is inconvenient to maintain, increasing the difficulty of equipment maintenance. The equipment is not easy to use, which is extremely unfavorable for the stable use of the equipment.

[0003] Those skilled in the art have conducted research and improvements, such as an ore mining and excavation equipment with application number CN202310353783.0.
