Welcome To C&M Mining Machinery
Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock. The resulting boulders are then ready for hauling; specialized haul trucks, conveyors, trains, andCopper mining in Arizona - Wikipedia,Copper mining in Arizona, a state of the United States, has been a major industry since the 19th century.
