Opencast Coal Mining Cost

Comparison of social costs of underground and open-cast ...

The total cost of mining includes the direct mining cost and social cost. The social costs include the impacts to the environment and socio-economic systems. According to the estimates for the complete costs of coal, coal mining only accounts for 22% of total social (external or “hidden”) costs of coal (Epstein, Buonocore et al., 2011).

Coal mining - Wikipedia

Most coal seams are too deep underground for opencast mining and require underground mining, a method that currently accounts for about 60 percent of world coal production. In deep mining, the room and pillar or bord and pillar method progresses along the seam, while pillars and timber are left standing to support the mine roof. Once room and pillar mines have been developed to a stopping ...
