Progress on implementation of drill jigs at Impala Investor visit 28 October 2005 Factors impacting team productivity • Older shafts with high team efficiencies being replaced by new deep level shafts • Distance (horizontal) from barrel affecting face time and thus mining cycles (affects blast frequ
Slide 2: Technology intervention / Potential DDT benefits
Technology intervention • Drill-jigs (DDT) technology on the Merensky horizon • Including in-stope bolting as a support system 3 Potential DDT benefits • Primary benefits • Safety • Remove rockdrill operators from danger area • Permanent support close to face • Reduction in number of FOGs • Secondar

Slide 8: Factors affecting drill jig implementation / Risks
Factors affecting drill jig implementation • Slow uptake by above average performing teams. • Prioritisation of roofbolt roll-out • Training period takes longer than anticipated. • Teams require consistent monitoring and coaching after training. 15 Risk associated with DDT implementation • Lack of t
Slide 9: The way forward / Targets for FY2006
The way forward • Drive R&D into and trials on bolters of less than 1m for the UG2 (±85cm) • Drive R&D into and trials on development technology to ensure availability of developed reserves • Revisit efficiency improvements in FY2007 and beyond, however FY2006 required as a learning period. • Contin
