Coal is mined using giant machines to remove the coal from the ground. There are two basic methods to remove coal: surface mining and underground mining. Surface mining is used when the coal is typically less than 200 feet below the surface. Giant machines are used to remove the top layers of soil and rock to expose the coal.
Oil is extracted from the ground using the three techniques of primary recovery, secondary recovery and enhanced recovery. These techniques are applied to oil extractions on land and at sea. The extraction process varies in duration but uses the same methods to remove oil from wells of all sizes.
There are two ways to remove coal from the ground: surface mining and underground mining. Surface mining is used when a coal seam is relatively close to the surface, usually within 200 feet. The first step in surface mining is to remove and store the soil and rock covering the coal (called the "overburden").
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. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity.

There are two main methods of underground mining: room-and-pillar and longwall mining. Room-and-pillar mining. In room-and-pillar mining, coal deposits are mined by cutting a network of 'rooms' into the coal seam and leaving behind 'pillars' of coal to support the roof of the mine.
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.
How is coal removed from the ground? - 3604021. Machines are used to remove coal from the ground, there are two ways, one of them implies surface mining, where they dig the dirt, then filter it to find coal, the second way implies underground mining, where workers go deep down, to find coal.
