At MINExpo INTERNATIONAL® 2016 Sandvik is launching the first in its next generation of in-the-hole (ITH) underground production drill rigs. The new Sandvik DU412i is automation-ready and is built on a modular standardized platform, delivering a truly flexible automated ITH longhole production and service hole drill.
Modularity and flexibility
Sandvik DU412i incorporates a completely new design, built on the proven Sandvik 400 range of center articulated, carrier-mounted ITH drill rigs. The Sandvik 400 range is ideal for highly accurate production drilling, as well as drilling service holes and slot raises. It drills with ITH hammers that are powered by on-board high-pressure screw boosters. These can be used to drill holes with a diameter of 89 to 216 millimeters (3 1/2 to 8 1/2 inches). The compressor control system controls the flow of air to remain constant, not just unloading when the pressure reaches maximum, which increases safety interlocks and full-time monitoring and data collection.
The updated drill module has fully modular feed, carousel and centralizers, facilitating maintenance and reducing service costs. At the same time it also has a rebuildable/reconfigurable system that allows for application changes at a later date and gives the customer the ability to change drill application by bolting on the new components that are needed.
Radio remote and automation for efficiency and safety
Radio remote tramming gives the operator the possibility to tram and set up the unit without being in the operator area, increasing safety and allowing extremely precise setup, with excellent visibility of the work area. The tramming can be done on either diesel power or using the electric power pack. The power pack is a multi-voltage compliant system that gives customers freedom to move the drill from one country to another. The drill operates easily in different networks ranging from 380V – 1000V and both 50 and 60Hz.
The onboard control system of Sandvik DU412i provides information on drilled holes such as angles, depth and penetration rate. Coupled with IREDES drill plan handling and drill diagnostics, consistent daily drill reports will improve and speed up the information that is available to engineering and operations departments. The radio remote functionalities also allow multiple units to be run from an operator command center, from which one operator is able to run several units at the same time. This makes Sandvik DU412i highly productive and cost efficient. The unit can also be integrated with Sandvik AutoMine.
