Longwall mining usually takes place deep underground, when excavating coal. The process relies on incredibly sophisticated interconnected pieces of equipment that work together in an efficient and safe mining operation. Source: Midwest A longwall mining site is usually 3 to 4 kilometers long and 250 to 400 meters wide.

Mar 25, 2021Surface Mining. Surface mining includes numerous techniques and is the most common method for non-fuel minerals, producing 97% of the amount mined. Miners choose surface extraction for minerals located close to the surface. There are three main ways to mine on the surface. These methods include quarrying, open-pit mining, and strip mining.

Miners use heavy mining machinery to drill wide steps known as benches, which separate the rock containing gold (ore) from the rock with no economic quantities of gold (waste). Next, blasting occurs to break down the rock making it easier to move. A fleet of excavators mine designated ore areas and move the gold containing ore to stockpiles.

The most productive underground method is known as longwall. A block of coal 200 to 300 meters wide and up to 10 kilometers long is defined by a set of tunnels. A cutting machine is then employed to cut the coal which is removed by conveyers. Opencast methods use large equipment to remove the rock above the coal, which can then be mined.

Jan 13, 2021This approach is still used, and it is relatively common in underground mining. With drill and blast, a miner clears an area out using explosives, such as ANFO or Emulsion. This breaks up the ore while giving them greater access to the area. Believe it or not, explosives have been used as part of the mining process since 1627.
