Surface mining is used when the coal seam is near the surface. It 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. How does it work The overburden of soil and rock is first broken up by explosives it is then removed by draglines or by shovel ...
