In 2009, Kentucky had the highest prevalence of cigarette smoking in the United States, at about 25.6% of the adult population. 1 Age-adjusted rates of lung cancer incidence and mortality in Kentucky are also among the highest in the nation, at 97.7 and 74.6 per 100,000 residents, respectively, in 2007. 2 These figures vary widely across the 120 counties in Kentucky; however, counties in the ...
Coal is mined by both surface or 'opencut' (or opencast) and underground or 'deep' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia's coal is produced from opencut mines.
Coal, now substantially depleted, is abundant in several areas of Great Britain, including some offshore areas, as well as in the industrial centers of Germany and in Ukraine. Other coals deposits are found in Belgium, France, Spain, the Czech Republic, Poland, Slovakia, and Russia. The burning of coal has produced high levels of air pollution.

The first major producer of this type was the Carlin deposit, which was discovered in 1962 and started production in 1965. Since then many more deposits have been discovered in the vicinity of Carlin, and the Carlin area now comprises a major mining district with seven operating open pits producing more than 1,500,000 troy ounces of gold per year.
Oil shale is a rock that contains significant amounts of organic material in the form of kerogen. Up to 1/3 of the rock can be solid organic material. Liquid and gaseous hydrocarbons can be extracted from the oil shale, but the rock must be heated and/or treated with solvents.

Coal mining - Coal mining - Coal deposits: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.
