Modern-Surface Mining When coal seams are near the surface‚ it may be economical to extract the coal using open cut (also referred to as open cast‚ open pit‚ or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods‚ as more of the coal seams in the strata may be exploited. Large Open Cast mines can cover an area of many square kilometers and use very large pieces of equipment. This equipment can include the following: Draglines which
