Taking the capability for breaking oversize rocks in the ore production cycle one step further. Integrating the patented Ro-Bust™ hydro fracturing system and MacLean’s PLC-controlled operating system, the Ro-Bust™ Blockholer provides the tools to safely and effectively break rocks without high explosives.
The MacLean Advantage:
- Oversize is fragmented at source, without damage to draw point infrastructure
- Greatly reduces fly rock and virtually eliminates blast-induced dust and noxious gases
- Significantly increases productivity of a stoping area by reducing ore flow interruptions
- Particularly effective in reducing LHD maintenance costs by eliminating overloading when carrying large boulders
- Increases stope value in NPV terms by allowing faster extraction of developed resources (blasted or caved ore)
- More effective than mechanical/hydraulic rock breaking, particularly boulders larger 2m in volume
Features
- Fully self-contained drilling system; no air or water services necessary
- Radio and optional video system designed for underground environment
- Hydraulic rock drilling
- Patented Ro-Bust™ rock breaking technology
- Heavy duty frame construction
- High-powered, electronically controlled Caterpillar™ engine option
- Reliable, proven power train components
- Four wheel drive carrier
Applications
- Situations requiring fast, real-time reduction of boulders to maintain continuous ore production
- Block cave and sub-level cave operations where interruptions in ore flow directly affect behavior of the cave
- Any other bulk mining method desiring to eliminate delays waiting for boulder breakage and blocked draw point blasts
