Although open pit mining (link to mining solution page) contributes about 85% of all mineral mining, it is one of the most environmentally taxing. About 73% of extracted rock goes to waste. Meanwhile, underground mining wastes only 7% of the extracted rock but is more expensive (Hartmann and Mutmansky, 2002).Mogalakwena Platinum Mine, Limpopo Province, South .Open-pit mining using truck and shovel operation is implemented at the Mogalakwena mine.

The Mining Life: Open Pit vs. Underground - MICROMINE

Open pit mines don't have to safeguard against loss of air and cave-ins, but they do have their own set of strict safety guidelines that save lives. While there isn't as much of a danger of cave-ins, rock slides and other hazards due to the structural integrity of the material the miners work in are still present.1 Alternatives 6.0 Alternatives 6.1 Introduction 6.2 Mining MethodOpen pit mining involves excavating overlying waste earth in horizontal benches to expose the target ore, which can then be removed for processing.
