Oct 31, 2019· Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.
Coal mining Coal mining Coal transportation: There are several methods for moving prepared coal from the mine to the markets. The cost of transport can be substantial and can account for a large fraction of the total cost to the consumer. Rail transportation is by far the most common mode of hauling coal over long distances.
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
Coal mining Coal mining Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to create adequate working height for
There are localized transport systems at the mining face areas to carry the coal from the cutting machines to the main transport systems. These localized transport systems (shuttle cars, AFC's, BSL's, etc) are dealt with in following sections relative to the different types of mining. This section refers to the main transport systems out of the

There are several methods for moving prepared coal from the mine to the markets. The cost of transport can be substantial and can account for a large fraction of the total cost to the consumer.
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.
However, once transport improved during the industrial revolution, coal could reach greater markets and expand, and this came first in the form of canals, which could be purpose-built and move large quantities of heavy material. Canals halved the transport costs of coal compared to the packhorse.
Coal is considered as the most polluting source of energy, which creates environmental problems at various stages of its procurement from mining, transportation, stock piling, coal preparation, and utilization (Pandey et al., 2014a).
Cleaned coal reduces transportation costs as well as reduced quantities of combustion ash requiring disposal. Coal preparation can also make marginal coal supplies suitable for sale. Conventional coal preparation involves cleaning and separation of coal-rich from mineral-matter-rich particles by size.
Trains / Rail Cars Fact: In the U.S. for 2005 Coal was the top commodity shipped over rail (40.7%). Kentucky has over 2,640 miles of railroad lines. Over 69 million tons of Kentucky coal were transported over these lines in 2005.

U.S. coal mining productivity, as measured by average production per employee hour, decreased 4.8% from the 2017 level to 6.23 short tons per employee hour. U.S. coal consumption decreased 4.0% from the 2017 level to 688.1 MMst. The electric power sector accounted for about 92.6% of the total U.S. coal consumed in 2018.
Unfortunately, in our reductionist age, too often people looking at the coal problem don’t consider the whole problem. Only by contemplating the entire life cycle of fossil energy—coal extraction, preparation, transportation, combustion, and waste disposal of by-products—can one fully understand the enormity of coal’s toxic legacy.
