2 Mining Methods Copper
blasting and grinding equipment are used to accomplish this task. open pit mining is a technique used to extract copper ore near the earths surface. open pit mining is the most widely used technique of mining copper today. It is accomplished by creating and using benches or terraces to gradually reach deeper under the earths surface. underground mining is used when the copper ore is not near the the first steps of copper processing are the same for both ores: mining and transporting. 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.dec 21, 2015 underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. drilling is normally required to place explosive charges to
