South African Rock Engineering Symposium

SARES 2014
"Creating value through innovative rock engineering "

12-14 May 2014 |Misty Hills, Muldersdrift

Recent events in the South African mining industry have led to the conclusion that it is time for significant change. Mining needs to become safer and more efficient while addressing the challenges of labour costs, marginal ore, complex geology and greater
mining depth. Innovative rock engineering design is therefore essential for the future of
the mining industry
