Sandvik Launches DU412i with V-30 for Slot Raising Applications

Sandvik Launches DU412i with V-30 for Slot Raising Applications

Sandvik Mining and Rock Technology has launched its first automation-ready, underground ITH longhole drill for production drilling, service support and mechanised slot raising. The DU412i is a truly versatile, automated longhole drill rig for a wide range of ITH applications.

Versatility and High Drilling Capacity in Underground ITH Drilling

For the first time in the global market, the DU412i introduces mechanised pipe handling in V–30 slot raising applications. The DU412i is Sandvik’s first fully automated ITH longhole drill. It is highly versatile, fitted with an onboard booster and a drilling module for fan or parallel 90-216mm diameter longhole drilling, using 3” to 8” ITH hammers. Equipped with the V-30 head, the drill provides mechanised reaming of 30” diameter slot raises.

The DU412i is available with high capacity onboard boosters and hammer pressure up to 28 bar. This ensures higher penetration rates, drilling capacity and supports hammers up to 8” at 24 bar pressure. The increased boom offset of parallel holes to 3000mm allows more holes to be drilled each set-up.


Productivity Increase with Automation and Teleremote Operation

The DU412i has automation packages for repeating drilling cycles with speed and precision. Unmanned drilling through breaks and shift changes increases fleet utilisation; one operator can supervise multiple units, improving product safety and productivity. The drill is equipped with a new, improved user interface on the drill or in the remote-control location. The standard Silver drilling package features single-hole automation (including uncoupling of pipes), while the optional Platinum delivers fan automation, drill plan management and as-drilled data download.

Teleremote drilling operation on the DU412i improves productivity and product safety. Radio-remote tramming gives the operator excellent visibility of the work area to safely tram the unit between fans and set it up very precisely without being in the operation area. The tramming is possible on either diesel power or using the electric power pack.


Improved Safety with Mechanisation in Slot Raising

The FOPS/ROPS cabin on the DU412i is the safest and the most comfortable working environment in underground drilling. It offers more open and spacious environment for the operator with increased visibility and low sound pressure level during drilling <75 dBA. The adjustable drilling control panel and seat improve comfort during operation, while tramming teleremote cameras are available.

In the V-30 slot raising configuration, the unit is delivered with blind bore feed and split centraliser, spaced out RH6250 rotation head and PC225 carousel. The storing capacity of the carousel allows up to 40m of continuous drilling and slot raising. The unit is fitted with KSU34 onboard booster (34 m³/min @ 28 bar) and single-hole automation for 6½” diameter pilot hole drilling and for reaming the pilot to 10” diameter can be utilised. Pipe handling during reaming the raise to 30” diameter with the V–30 head is mechanised.

The layout of the carrier allows ground access to all service points, while swing-out frames offer ease of access to other components and safety in service.
