Limestone is found near the surface (called a surficial deposit); hence, it is produced mainly from surface mines.By and large, limestone is mined by two methods: opencast stripping for hilly deposits and open-pit mining for plain deposits. To meet the industrial requirements of a large country like India, medium- and small-sized mines of …

The limestone averages 18.3 m (60 ft) in thickness, with mining planned in two lifts (i.e., initial development and benching). The height of the initial development was 7 m (23 ft). Secondary bench mining removed an additional 9.1 m (30 ft) from the floor, resulting in a total planned mining height of 16.2 m (53 ft).
