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.

Oct 01, 2020 Their use increased particularly in energy supply and production of electricity and heat, replacing hard coal. The consumption of natural gas went up by 11 per cent and that of peat by 15 per cent from the previous year. Respectively, the use of hard coal in energy supply decreased by five per cent from last year.
The paper explores the industrial tourism development potential of a former mining area in Petrila, Jiu Valley, Romania, drastically affected by deindustrialization, in order to build a theme park in the old mine site. The research context is determined by the current economic and social state of the area, and also by the potential of the identified industrial heritage elements.
