Mining of a diamond-bearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ‘‘open-pit’’ or ‘‘open-cast’’ mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks. Hard rock is drilled and blasted with explosives so the broken material can be removed.
