Surface mining activity includes the extraction of coal directly from the ground or from waste or stock piles, pits or banks. A permit is required to conduct surface mining activities. Permit area includes mining and support areas, facilities and roads. Permits are also required for exploration activities and processing plants.
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 is called a 'pit ...
Jun 22, 2018 · The mining process can be broken down into two egories: Surface Mining. Workers begin by striping the overburden, which is rock, soil, and ecosystem that lies above the surface. Underground mining. The digging of tunnels and sink shafts when the ore—or mineral deposit—is below the surface. Hand tools such as chisels, hammers, and wedges ...

Jan 01, 2016 · 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.
Μining waste, processing byproducts and mine water discharges pose a serious threat to the environment as in many cases they contain high concentrations of toxic substances. However, they may also be valuable resources. The main target of the current review is the comparative study of the occurrence of rare earth elements (REE) in mining waste and mine water discharges produced from .
