Coal mining - Coal preparation: As explained above, during the formation of coal and subsequent geologic activities, a coal seam may acquire mineral matter, veins of clay, bands of rock, and igneous intrusions. In addition, during the process of mining, a portion of the roof and floor material may be taken along with the coal seam in order to ...

Uses. Coal is used for electricity generation, the manufacturing of steel and cement, and various industrial and residential applications. Canada produced 61 Mt of coal in 2017, of which 56% is metallurgical coal used for steel manufacturing and 44% thermal coal used for electricity.
Coal mining has been performed since the arrival of the Industrial Revolution in the mid-18th century. Coal is used as a fuel primarily for steam-generated electrical power plants, as well as being a component of certain industrial applications, such as steel manufacturing.
Surface mining is only economic when the coal seam is near the surface. This method recovers a higher proportion of the coal deposit than underground mining as all coal seams are exploited - 90% or more of the coal can be recovered.
