coal from surface mining data

Coal mining World Coal Association

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 Large opencast mines can cover an area of many square kilometres and use very large pieces of equipment such as...
