The mining waste burden and management problems are particularly important due to the high volume of material disposed. According to the Central Statistical Office (2002), the total amount of mining waste (including tailings from preparation plants) generated in 2000 in Poland was as high as 73.6 million tons (Mt), i.e. 59.5% of the total waste
Fine coal waste from the preparation plant can be reduced or eliminated during both the mining and the preparation phases. For example, selective mining reduces the amount of noncombustible material. However, many of the coal seams currently mined are of sufficiently low quality that they would not be mined if this were required.
These are based on visits to both underground and surface coal mining facilities to survey the coal waste management practices as well as based on a review of their mine permits. These visits were made to observe mining, processing, and coarse/fine coal processing coal waste disposal operations and water management at the sites.
History. Mining waste is one type of special waste When EPA proposed regulations for managing hazardous waste under Subtitle C of Resource Conservation and Recovery Act (RCRA) on December 18, 1978 (43 FR 58946), the agency deferred hazardous waste requirements for six categories of waste—which EPA termed “special wastes”—until further study and assessment could be completed
Coal mining and coal combustion in power plants produce several types of wastes: The mining process itself produces waste coal or solid mining refuse, which is a mixture of coal and rock.; The mining process also produces liquid coal waste, which is then stored in impoundments.; Pollution control equipment used for coal combustion produces coal ash or fly ash, as well as flue-gas
Although electric utility companies produce ash at their coal-fired power plants, most utilities do not handle, dispose of, or sell the ash that they produce. For the most part, management of bottom ash or boiler slag is contracted out to ash marketing firms or to local hauling contractors.
A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.
A spoil tip (also called a boney pile, gob pile or culm bank) is a pile built of accumulated spoil waste material removed during mining. These waste materials are typically composed of shale, as well as smaller quantities of carboniferous sandstone and various other residues. Spoil tips are not formed of slag, but in some areas they are referred to as slag heaps.

Fly-ash and coal gangue are the two main industrial solid waste in China. The chemical compositions (shown in Table 1) were SiO 2, Al 2 O 3, Fe 2 O 3 and some impurities. As the coal gangue is main solid waste for coal mining, one of the most common approaches to waste rock is to stack construction that encapsulate the most pyrite rich rocks in the core of a waste rock stack (Lottermoser, 2003

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine a pit, and the

It can be categorized as carbon steel slag and stainless steel slag according to the type of steel, and as pretreatment slag, Linz-Donawitz (LD) converter slag, electrical arc furnace slag (EAFS), ladle refining slag and casting residue according to the steelmaking process (Meng and Liu, 2000).

It will also extend the productive life of the mining complex, featuring an open cut thermal coal mine, coal handling and preparation plant, as well as associated infrastructure, to 75 years from 45. Lynham referred to the extension as a vote of confidence in the state’s resources by Yancoal.
The coal slurry, a waste byproduct from coal mining, overflowed from an abandoned area of an underground coal mine in southern Fayette County where Jim Walter Resources was legally pumping the watery sediment. Pumping equipment malfunctioned, causing the slurry to spill into an unnamed creek and eventually Freeman Creek, a tributary of North River.
The environmental impact of the coal industry includes issues such as land use, waste management, water and air pollution, caused by the coal mining, processing and the use of its products. In addition to atmospheric pollution, coal burning produces hundreds of millions of tons of solid waste
