Sandvik introduces Sandvik DL422i top hammer longhole drill rig

Sandvik Mining and Rock Solutions has introduced its newest i-series top hammer longhole drill rig, the .

Following the launch of the Sandvik DL422iE battery-electric drill in 2021, Sandvik has now introduced its diesel counterpart, designed for underground mass mining in 4 x 4 m or larger production drifts.

The Sandvik DL422i offers the same productivity, reliability and high utilisation of its battery-electric counterpart for operations with challenging site conditions that are not optimised for a battery-electric fleet, the company explained.

“The new DL422i expands our i-series longhole production drill offering with traditional diesel engine layout, and starts to take over the work load of its famous predecessor, Sandvik DL421,” Sami Anttila, Product Line Manager, Longhole Production Drilling, said.

The Sandvik DL422i prioritises automated operations, fleet connectivity, availability of data and improved hole accuracy, supported by Sandvik’s technical support and operator training for an improved user experience, the OEM says. Automated operations over shift changes allows up to 20% increased productivity and up to 10% more drilled meters in a shift.

The longhole production drill is a highly intelligent and automated drill in Sandvik’s i-series underground drilling offering, with options for both automation and tele-remote operation.

It is compatible with Sandvik’s Platinum level automation package, which includes one-hole and fan automation, automatic boom repositioning to the next hole, automatic stinger control, drill plan and as-drilled data management (WLAN), plus connectivity to My Sandvik remote monitoring and Sandvik DrillConnect mobile application. Later in 2022, the Sandvik DL422i will also be compatible with Sandvik’s tele-remote drilling and tramming offering, expanding remote control from single to multiple units from a single console.

In operations with low, or no, mine network connectivity, the Sandvik DrillConnect mobile application can be used for easy and smooth drill plan transfer, comprehensive data collection, and intelligent troubleshooting, according to the company.

The Sandvik DL422i is billed as providing maximum productivity and safety, having been developed with the future of mining in mind. The control system platform allows for new technology implementation during the product lifetime, while tele-remote and automated drilling allows for unmanned operation through shift changes and breaks, increasing fleet use.

The powerful HF1560ST rock drill offers improved energy transfer and stability with high penetration rates and drilling capacity, Sandvik added.

Sandvik’s new i-class cabin provides the safest and most comfortable working environment with improved visibility in operation, reduced sound pressure level during drilling, adjustable drilling control panel, and multi-purpose seat with back and head support, Sandvik says. Swing out frames, meanwhile, provide easy, safe and fast access to the main components from the ground level.
