Open-pit mining is much safer than shaft mining. In underground mining, the threat of a cave-in or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in cave-ins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.

Block caving is essentially the underground version of open-pit mining. Its the only underground mining method that can reach similar production rates to surface mining operations, up to over 100,000 tonnes per day. The method involves undermining an ore body, then allowing it to collapse under its own weight.
