Coal mining and logistics covers coal extraction from mines, coal preparation and transportation to the final users such as power plants or industrial plants. Coal Mining - There are two mining methods for coal extraction depending on the geology and economics of the deposit: underground mining (60% of world coal production) and surface mining ...
Longwall mining is one of the oldest methods of mining coal. Before the widespread use of conveyor belts, ponies would descend to the deep, narrow channels and haul the coal back to the surface. Today, almost a third of American coal mines use longwall mining. Outside the U.S., that number is even higher.
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.

Here is a picture of a coal miner from 1814, when the Industrial Revolution was gathering pace. In the background, there is a steam-powered locomotive, used to transport the coal in waggons along rails, and steam-powered mine machinery, designed to help the miners bring the coal to the surface and to pump out water from the mine.
Underground mining, sometimes called deep mining, is used when the coal is buried several hundred feet below the surface. Some underground mines are 1,000 feet deep. To remove coal in these underground mines, miners ride elevators down deep mine shafts where they run machines that dig out the coal. Read about a visit to a real underground coal ...
· After coal is mined, is it ready to be shipped. If the mine is close to a destination, trucks can carry the load. Using conveyors to move coal is another option for shorter distances. In 68 percent of cases, coal is transported by the railroad. This can be very expensive. Sometimes the cost of shipping coal by train is more than the mining costs.
Underground Coal Mining. Underground mining involves opening one or more portals or shafts into the earth that follow or intercept coal seams that are too deep for surface mining methods. Two main methods of underground mining are practiced in Pennsylvania: ... As the coal is removed and transported away via the conveyer, the roof supports are ...
Underground mining, sometimes called deep mining, is necessary when the coal is several hundred feet below the surface. Some underground mines are thousands of feet deep with tunnels that may extend out from the vertical mine shafts for miles. Miners ride elevators down deep mine shafts and travel on small trains in long tunnels to get to the coal.
Coal mining - Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many technological, economic, …
Where it can be used, it permits recovery of 90 percent or more of the coal to be mined. Underground mining is used to extract coal lying deep beneath the Earth's surface or in seams exposed on hillsides. The coal is reached by drilling two openings into the coal bed to transport workers and equipment and to send coal to the surface.
Types of coal mine. Shaft mine – Miners and equipment are transported down vertical shafts hundreds or thousands of metres deep to access fertile coal seams. Drift mine – The simplest method of underground mining, the coal seam is accessed by digging horizontally into the side of a hill.
Underground mining is when the coal is farther underground, making it too expensive to remove soil. 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. Coal mining has had many developments over the recent years, from the early days of men tunneling, digging ...
Underground (or deep) mining is used when the coal is buried deep within the Earth. Some underground mines are 1,000 feet deep! To remove coal from underground mines, miners are transported down mine shafts to run machines that dig out the coal. Processing and Transporting Coal After coal comes out of the ground, it goes to a preparation plant ...
This section refers to the main transport systems out of the mine. Before the development of suitable conveyor belts, coal was transported from the mine by rail transport systems, but today coal transport is almost invariably by conveyor belts. In a mine with drift or adit access, the conveyor transport can be all the way to surface but in a ...
deep coal mine is reverse transport - transport of materials and mine equipment to individual mine positions. Transport at deep coal mines has to ensure the perfect compliance among the all components of the haulage process. The increasing demands on underground transport lead often to

Fact sheet - Subsidence from longwall coal mining. ... The coal is collected on a conveyer and transported to the mine's processing facilities. Figure 1. View of coal shearer and hydraulic supports along a longwall face. ... The amount of subsidence above a deep longwall mine is typically 1 to 2 metres, but could be 2 to 3 metres for a thick ...
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation.

Conveyors or cars (railway wagons) transport the coal to vertical shafts for removal from the mine. After the coal is brought up to the surface by conveyors, it undergoes a process that removes sand and mud by immersing the coal in a solution of water and tiny magnetite particles. The …
"The last deep mine ponies came out of Ellington Colliery in 1994. Two of them, Carl and Sparky, came to us at the Museum to live out their retirement. In Wales, there were a number of privately owned drift mines that continued to use horses and ponies as this was a cheaper means of getting coal out compared with the cost of mechanized haulage.

The Powder River Basin is the largest coal mining region in the United States, but most of the coal is buried too deeply to be economically accessible. The Powder River Basin coal beds are shaped like elongated bowls and as mines expand from east to west in the Powder River Basin, they will be going "down the sides of the bowl".
CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act of 1976 charged OTA to assess the feasibility of the use of deep-mining technology on leased areas. With the passage of the Sur-face Mining Control and Reclamation Act of 1977 congressional interest in the study of deep underground mining technology shifted
But those depths are extreme; most top (or bottom) out at about 1,000 feet (300 meters) [sources: Times Wire, ARMZ, Illinois Coal Association]. Mining has changed a lot from the images we have of the 19th century when men with shovels toted canaries to make sure the air underground was not toxic.
