Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
coal mining humans suffer from coal mining inside underground workings but opencast mining creates much more air quality deterioration in respect of dust and gaseous pollutants in and around the mining complexes. Opencast mining dominates the coal producti on scenario in India due to the techno-economic factor, better safety, etc.
