Coal waste

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 .Dust Suppression Planning When a coal mine is in the process of implementing a dust suppression plan, cost ai plays a large role in product selection When looking at a product, an overall cost an should be taken into account According to Bolander and Yamada () in a report.
