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.

Strip 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.

Open 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.

2020-6-15Mining is a practical industry that seeks efficient ways to extracts mineral wealth from the ground. 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.

Open-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.

Mining 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.
