Openpit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Openpit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels.
Open pit mining or strip mining is an extraction process for ore or fossil fuels that takes place at the surface of a mining site. Worldwide, 40 percent of mining occurs at the surface, according to Greenpeace International. Compared with underground mining, surface mining is much more efficient.

The coal sector has faced many obstacles through the years and today it''s no different. The sector continues to endure low prices and tough market conditions forcing many companies to cut back on operations and their workforce. The need for coal, however, is still prevalent.
