Narrow Reef Stoping
The HV212 Hydrovessel drilling system is a complete instope drilling system, replacing conventional compressed air drilling systems, which allows for faster access to ore reserves.
The proven reliability and fast penetration rate of this system reduces face time required to obtain a full effective blast, reducing water usage and increase production.
