Open Pit Mining Pros Cons | Sciencing
Openpit mining is much safer than shaft mining. In underground mining, the threat of a cavein or release of toxic gas is a constant concern. When shaft mining was the most common method of ore extraction, thousands died in caveins, gas events and accidents involving equipment. In 1907 alone, more than 3,200 deaths related to mining occurred.
