Block caving is essentially the underground version of open-pit mining. Its the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.

Read MoreStrip mining and subsurface mining Strip mining or surface mining is performed when surface soil and rock are stripped off to reach the mineral of concern. When such operations are done, surface water bodies lakes, streams, etc gets acidity. Acid mine drainage occurs when water molecules infiltrates the spoil banks. The water reacts with sulfide minerals to produce sulfuric acid.
Read MoreOpen pit mines can be used in coal mining, and they are used extensively in hard rock mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.

If you are in an underground mine you cant see the sky. In general, underground mines have a much lower environmental impact than strip mines or other open pit mines.
Read MoreOpen pit mining does offer some advantages over traditional deep shaft mining. Pit mining is more cost effective than shaft mining because more ore can be extracted and more quickly. The working conditions are safer for the miners because there is no risk of cave in or toxic gas. Open pit mining.
Read More2020-7-1Underground Mining. Underground mining, where miners tunnel beneath the Earths surface to extract mineral deposits, is rarer than open-pit mining. In 2014, it made up about 5 of all American mining operations and has less of an impact on the surface. However, this doesnt mean that underground mining doesnt have an effect on the.

During the nineteenth century, precious metals deeper than about three hundred feet called for underground drift or hardrock mining. Occasionally, ore bodies sufficiently close to the surface made open pit or open cast mining practical.

Read MoreOpen-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
Read MoreMining Mining Underground mining When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the.
Read MoreOpen pit mining. a giant hole called a quarry is dug in the ground to extract the minerals . iron,copper stone and gravel are usually extracted during this process. often used for mining coal is a direct vertical shaft to vein of ore . the ore is broken up underground and then hoisted through the shaft in buckets.
