Open-pit mining is a surface mining technique that involves extracting minerals close to the surface from vertical pits. It''s the most common mining method in the world. Materials extracted from open-pit mines include clay, coal, and copper. Open-pit mines that produce building materials and dimension stone, like limestone, granite, and ...

 · Mining activities started in the early 1990s and by the end of 2007 there were already 66 domestic mining operations registered in the region (). These mining activities have led to the severe degradation of the fragile local environment on the Plateau due to the lack of adequate management and planning, as well as poor operating experience and waste management ( Lin et al., 2007 ).

Coal mining takes place either underground or through surface/ opencast operations. The method used depends on the geology of the coal deposit. When is this used? 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 ...

Surface mining and deep underground mining are the two basic methods of mining. The choice of mining method depends primarily on depth, density, overburden, and thickness of the coal seam; seams relatively close to the surface, at depths less than approximately 55 m (180 ft), are usually surface mined.

In general, open pit mining is used where the deposits are close to the earth surface, whereas the underground mining is used for deep deposits on average greater than 100 meters deep. Open-pit mining requires the removal of soil and waste rock on top of the ore to expose the hard rock.
