Coal Miner gives you the possibility to take control of numerous mining equipment. They will introduce you into the world of coal, dust, and danger that awaits miners. During the gameplay, you''ll learn to use the machines and also solve logistic problems related to coal distribution.
Mountaintop removal mining (MTR), also known as mountaintop mining (MTM), is a form of surface mining at the summit or summit ridge of a mountain. Coal seams are extracted from a mountain by removing the land, or overburden, above the seams.This process is considered to be safer compared to underground mining because the coal seams are accessed from above instead of underground.

Mining - Mining - Surface mining: It has been estimated that more than two-thirds of the world''s yearly mineral production is extracted by surface mining. There are several types of surface mining, but the three most common are open-pit mining, strip mining, and quarrying. These differ from one another in the mine geometries created, the techniques used, and the minerals produced.
Plowing is the preferred longwall mining technique for seams below 1.8 m (71 in), and under specific geological conditions, even below 2.3 m (90 in). Today, is the market leader in the field of fully integrated and automated plow systems.

Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic
Longwall mining is extraordinarily efficient. Rather than drilling through the ore deposit, a longwall machine cuts across it, shaving off slices up to 600 feet (182 meters) long. Those slices drop directly onto a continuously moving conveyor, which carries it to a haulage shaft that lifts it out of the mine. In longwall mining, the roof ...
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 ...
