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.
