Deeper open pits
Monday, December 07, 2009
Surface mines are always seeking to extract more from their existing ore bodies by going deeper, or steeper, or both. Doug Minchin, Director, Rock Australia notes that as well as open pit mines getting larger and deeper, slope design is becoming more aggressive with concomitant high risk in size of failures and consequences. "Slope Failure, even a small rock fall threatens the safety of personnel, plant and equipment, productivity and potentially overall mine viability." read more »
