Site Visit – Underground Tour of Creighton Mine’s Deep Operations

21 October 2019 | Creighton Mine, Vale Canada Ltd., Canada

Creighton Mine is located 20 km west of Sudbury, and is one of the six underground mines being currently operated by Vale. The mine has been in production since 1901, and its present extraction rate is approaching 2,200 tonnes per day. As is expected from a mine in production for more than 100 years, several mining methods were used at Creighton. In the upper area, blastholes, cut-and-fill, and vertical retreat mining have been used. Today’s most economically important area of the mine is located between 7,400 ft (2,255 m) and 8,200 ft (2,500 m) and is known as Creighton Deep, where high magnitude seismic events have occurred due to the mining depth and the presence of major seismically-active structures. In order to reduce the seismic risk to As Low As Reasonably Achievable (ALARA), the mine is actively using various control measures, including a unique mining method of a pillarless slot-and-slash and a top-down centre-out sequence, an identification of high seismic risk areas by using Hazard Mapping Techniques and the use of various dynamic ground support systems.
