RUC Mining is regarded as the industry leader in this specialised area, having extensive experience across the widest range of conditions.
With a large fleet of raise boring equipment suitable for every situation, RUC is in a unique position to deliver the most effective solutions, whether raise drilling of vertical shafts, or vertical and inclined drilling of boxholes.
Applications include - pilot hole reaming for shaft sinking, escape rises, ore passes, ventilation shafts and borehole hoisting.
There are few innovations that have given miners as many benefits as modern raise drilling. By reaming rather than blasting, smooth-walled bores are created that may need little or no ground support. Diameters can range from 0.66m to over six meters, with pinpoint accuracy delivered up to 1,000m in depth.
The implications for safety and manning levels are just as impressive. By using non-entry methods, no personnel enter the hole during boring, no blasting takes place and there is limited exposure to falling rocks or harmful exhaust fumes. With only two operators generally required per shift, cost benefits are obvious - raise drilling is by far the safest and most cost-effective approach to creating vertical and sub-vertical openings in mines and construction projects.
