The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.
The coal sector has faced many obstacles through the years and today it's no different. The sector continues to endure low prices and tough market conditions forcing many companies to cut back on operations and their workforce. The need for coal, however, is still prevalent. According to the National Mining Association (NMA), the average American uses roughly 3.4 tons of coal each year.

Coal is a rock formed from the decomposition of plant life. It is primarily composed of carbon, with many other trace elements. Coal's high energy density and extensive reserves found in nature make it useful as a fuel for electricity generation in coal-fired power plants, and in some places, heating.
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.
Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties of coal arise because of differences in the kinds of plant material (coal type), degree of coalification (coal rank), and range of impurities (coal grade).

The largest and most long term effect of coal use is the release of carbon dioxide, a greenhouse gas that causes climate change and global warming. Coal-fired power plants were the single largest contributor to the growth in global CO 2 emissions in 2018, 40% of the total fossil fuel emissions. Coal mining can emit methane, another greenhouse gas.
When contour mining becomes too expensive, additional coal can often be produced from the mine's highwall by the use of augers or highwall miners. Open pit mining is usually found where coal seams are thick and can reach depths of hundreds of feet.
The choice of cooling system used in a coal plant affects not only its water requirements but also the efficiency of the power plant as a whole. According to estimates by the US Environmental Protection Agency (EPA), coal plants that use dry cooling produce about seven percent less power than those that use wet-recirculating systems.
