Miningselected waste (or simply mining waste) can be defined as a part of materials that result from the exploration, processes, the amounts and types of wastes as well as a short description of the national legislation of the various Member States. According to the returned questionnaires,
In recent years, kaolinitebased wastes are focusing the attention of researchers to obtain recycled metakaolinite, with consequent environmental and socioeconomic benefits. One of these lines of research is based on coal mining waste, which once activated thermally, it
Mining Waste. Mining wastes include hard rocks, gravels, clays, pebbles, sands, limestones, chalks, siftings of fine fractions, dump tailings of flotation concentration of ferrous and nonferrous metal ores, sulfur ores, apatitenepheline concentrates, coal wastes, halite flotation wastes, screenings of phosphorite, phosphoric ore fines, etc.

Management of coal combustion wastes 5 Burning coal in a coalfired power plant produces a variety of solid residues known as coal combustion products (CCPs), coal combustion residues (CCRs) or coal combustion wastes (CCWs). CCPs are now more commonly called coal combustion byproducts (CCBs) because of their increasing beneficial use.
#0183;#32;Introduction Annual volumes of the coalmining and processing wastes stored on the territory of Russia are approximately 15 million tonnes [1,2]. As a rule, during surface mining one ton of coal leaves 4 tons of overburden and its storage leads to a considerable environmental pollution.

Coal mining played a supportive role as provider of energy to the growing gold mining industry and indeed, many collieries were historically and are today owned by gold mining companies. To these coal mine owners it was more important to keep the costs of their own energy inputs low, than to profit from coal mining itself4. The coal

In the 21st century coal becomes the major and soon the main energy source. The largest coal regions of Ukraine include Donetsk, LvivVolyn
