The rooms can be mined out using conventional charge-and-blast techniques or, more commonly now, with a machine called a continuous miner. The continuous miner drills into the rock until it forms an excavated room, perhaps 20 to 30 feet (6 to 9 meters), leaving in place a rock pillar to support the "roof" [source: United Mine Workers of America ].

Aug 08, 2020· Open-pit mining uses large holes in the ground that are excavated to the depth of the desired product, and are common for sand, gravel and copper mines. Mining machines called draglines use a moving bucket to scrape away the soil lying over the ore deposit. Draglines can move the soil to a waste pile away from the pit, or dump the material into large trucks that transport it away from the site.
