  • OSMRE AR Impoundments - Office of Surface Mining

    Coal waste is produced during the cleaning of coal for market, and usually occurs at coal preparation plants. The coal cleaning process produces coarse (usually 6-inch or smaller material) and fine coal waste (silt/sand-size particles, usually in a slurry with water) as the impurities are segregated from the clean coal.


    Coal is mined by two main methods: underground mining and surface mining. The choice of method is determined by a number of factors such as geological characteristics, the quality of the coal, and the cost to extract the coal. In general, deeper lying coals will be mined using an underground process.
