FACT SHEET JULY 2018 SAFETY IN GOLD MINING

the gold mining environment are generally challenging. Mining is typically undertaken in narrow, often steeply dipping reef stopes and is still a largely labour-intensive process. Working places are increasingly distant from the shafts that serve them, involving longer underground travelling times at the start and end of each work shift. Virgin rock temperatures can reach up to 60ºC at the
