Surface mining is an efficient method for mining some minerals, especially coal, from deposits near the surface. It uses very large equipment to strip away overlying material, extract the coal, and then fill in the mined valleys.
Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.
Coal surface mining. Coal underground mining. Coal mining is the process of getting coal out of the ground. ... In this process, coal miners and all of the coal mining equipment are brought deep underground and coal is carried up out of the ground. This is especially dangerous because of fires, explosions, and poison gas in coal mines.
The surface mining equipment segment accounted for a revenue share of over 40% in 2017 and is anticipated to grow further during the forecast period. Currently, almost all metallic and non-metallic minerals along with a larger fraction of coal are mined via surface mining methods, which is expected to provide an impetus to the segment growth.

Miners use a variety of processes to mine the coal from underground and surface mines. One of the main types is Longwall Mining. Explain the process, the equipment used, and the problems encountered by miners who do this type of mining.
Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.

In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit.
Mining Equipment Market Overview: Global Mining Equipment Market is expected to garner $155.9 billion by 2022, registering a CAGR of 7.9% during the forecast period 2016 - 2022. Mining is an extraction process of obtaining coal, minerals, metals and other such materials from the earth.
Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, giant machines remove the top-soil and layers of rock to expose large beds of coal. Once the mining is finished, the dirt and rock are returned to the pit, the topsoil is …
Common Equipment Used in Surface Mining. There's a specialized and diverse set of equipment commonly used during the surface mining process. If you're going to work at a surface mine, it helps to know the names of the following equipment and what they're used for.
Surface Coal Mining. The primary methods of surface coal mining used in Pennsylvania are: Strip Mining: Layers of soil and rock overburden are removed the coal exposed coal seam is excavated.The area is then backfilled, regraded, and replanted during the reclamation process.

Coal is mined in Appalachia by both surface and underground mining techniques. Surface coal mining methods in the steep terrain of the central Appalachian coalfields include mountaintop removal, contour, area and highwall mining.
Coal mining equipment at the Coal Mining Heritage Park Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity.
Surface mining is sometimes known as open-pit, open-cut or open-cast mining and is only commercially viable if the deposit is located relative close to the surface. Less than 20% of Alberta's bitumen reserves are close enough to the surface to be mined.
Surface mining is used to extract about 70 percent of the coal in the United States. Surface mining can be used when the coal is buried less than 200 feet underground. In surface mining, the topsoil and layers of rock are removed to expose large deposits of coal.
Coal mining typically requires two methods of operations: underground and surface mining. The method is differentiated by whether the seam is relatively close to the surface area or buried deep below.
In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and ...
