Way we cost underground coal mining systems by G.H. Lind Synopsis This paper discusses the traditional costing approach currently used in the underground coal mining industry. Activity Based Costing ABC is identified as being a potentially more effective manner in which to cost underground coal mining systems. With
Coal mining is generally classified as either surface or opencast mining and underground or deep mining. Generally the type of coal mining selected is determined by the geological characteristics of the proposed mine the location of the coal seam or seams and the equipment available at the time the mine is to begin operation.

LONGWALL MINING Overview. In the method of secondary extraction known as longwall mining a relatively long mining face typically in the range 100 to 300m but may be longer is created by driving a roadway at right angles between two roadways that form the sides of the longwall block with one rib of this new roadway forming the longwall face.
Coal mining extraction of coal deposits from the surface of Earth and from underground. Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th
Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice typically 0.61.0 m 2 ft 0 in3 ft 3 in thick. The longwall panel the block of coal that is being mined is typically 34 km 1.92.5 mi long and 250400 m 8201310 ft wide.
This trend is increasingly perceptible in several steel manufacturing companies pursuing to enter the mineral exploration sector for securing their supplies of coking coal and iron ore at a rational cost. Equipment Insights. Surface mining equipment held the largest share of the overall revenue in 2019 and is expected to maintain its lead over
Coal prices at surface mines are generally lower than prices at underground mines. In locations where coal beds are thick and near the surface such as in Wyoming mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper such as in Appalachia.

When coal seams are near the surface it may be economical to extract the coal using open cut also referred to as open cast open pit mountaintop removal or strip mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods as more of the coal seams in the strata may be exploited. This equipment can include the following Draglines which
