APPROACHES TO IMPROVE SAFETY AND RECOVER LOST PRODUCTIVITIES IN VERTICAL SHAFT SINKING BY MAKING USE OF INDUSTRIAL ENGINEERING AND RISK DRIVEN 3-D MODELLING TECHNIQUES (2009)
Over several decades in Southern Africa the advance rates when sinking vertical shafts have declined significantly. The upside has been a substantial improvement in shaft bottom conditions and a commensurately improved safety performance, with an increasing number of shafts being sunk without fatalities and disabling injuries. This paper briefly reviews historical sinking rates and matches changed sinking productivity to the introduction of new sinking methods that have been adopted to eliminate/mitigate safety risks.
