How Underground Mining Works

Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.

Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Open pit mines may be circular, like the ones shown pictured at the Ekati mine, or oblong, and include several mining levels know as benches. Roads, known as ramps, allow access to the orebody. The size and depth of an open pit is a balance of how much worthless waste rock must be mined to gain access to the valuable ore.

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments. In-situ mining

In addition to the structure of the actual deposit, the geotechnical conditions often plays a defining role in the selection of a suitable mining method and thus of the entire mine planning.

open cast mining shaft mining and dredging mining #;#;Underground Mining is a method of Mining, where the mineral is extracted without removing the top soil and rocks. In this way we do not disturb the surface feature such as forest, agriculture land, rivers and residential areas.

Mining excavators from Colmar are used widely in open-cast mining. Extremely large machines are produced in Colmar. The largest excavator in the product range of -Mining Equipment Colmar SAS is a giant: the R 9800 is 11 metres high and, with a curb weight of 800 tonnes, it is nearly three times the weight of an Airbus A380.

Open Cast Mining: When minerals are taken out by removing the surface layer, the process is called open-cast mining. Minerals which lie at shallow depths are extracted by this process. Shaft Mining: When deep bores (called shafts) are made to reach the mineral deposits at great depth, the process is called shaft mining.
