How is coal mined and extracted? Planète Énergies
At each level where coal is present, the shafts connect to a grid of huge galleries (10- to 20-square-meter sections) that can extend over dozens of kilometers. The longwall method involves using a machine called a shearer Mechanical cutting machine used to extract coal in underground mines. that looks like a huge plow. The shearer slowly

Coal Mining and Processing Energy Trends Insider
Processing the Coal. After coal comes out of the ground, it typically goes on a conveyor belt to a preparation plant that is located at the mining site. The plant cleans and processes coal to remove dirt, rock, ash, sulfur, and other unwanted materials, increasing the heating value of the coal. Source: Energy Information Administration

4 Coal Mining and Processing Coal: Research and
The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2

Coal National Geographic Society
Dec 22, 2012· Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.

Machines Used in Coal Mining Career Trend
The panel being worked on may be up to 800 feet in width and 7,000 feet in length. Mined coal is deposited onto a conveyor that moves the coal to a collection area. Hydraulically powered shields over the machine provide ceiling support. Longwall mining is more efficient than room and pillar mining, but the equipment is more expensive.

Coal found in sedimentary rock, is crushed into the appropriate size and used as fuel for electricity generation or the iron-making process. Lumps of coal can be used directly as a fuel. However some coal is first washed to make it into 'high grade coal'. It can also be sorted into various sizes, depending on what the fuel is required for.
