Some of the biggest diamond mining operations in the world – De Beers and Alrosa, to name two – use open-pit mines. There is a certain financial practicality that comes with the open-mine operation; when there is a big hole in the ground, accessing the layers of rock hidden beneath is no mystery. Large amount of rock can be dredged up quickly and relatively safer for workers, and both of those things
