COAL MINING AND THE ENVIRONMENT

support methods, with the coal being extracted between the pillars, which then remain to support the roof. A small quantity of coal is mined by longwalling, when all the coal in the seam is extracted and the roof is permitted to collapse behind the mined-out area. Of all these methods, strip mining is probably the most environmentally friendly.
