SWEDEN – Epiroc, a productivity partner for the mining industry, has introduced the DM30 II Single Pass (SP) rotary blasthole drill for quarries and small open-pit mines. The crawler-mounted, hydraulic tophead-drive rig offers faster hole-to-hole drilling and lower unit costs through single-pass capability.

Built off the same reliable platform as the Epiroc DM45 and DML blasthole drill rigs, the DM30 II SP is suitable for a variety of single-pass rotary and down-the-hole (DTH) applications. It can achieve a clean hole depth of 11 meters in single-pass applications. The small footprint of the DM30 II makes it easy to maneuver on tight benches and simple to transport within the pit and over the road between pits.

The DM30 II SP offers a low total cost of ownership, with a design life of over 45,000 hours. The single-pass capability allows for faster hole-to-hole drilling and decreases the unit costs. Its design and layout allows for quick and easy access to all major service points.

The DM30 II SP is designed to handle 4-inch to 6½-inch drill pipe and a hole diameter of 140 mm to 200 mm. A 36-foot single-pass tower option increases productivity for 29 foot to 36 foot drilling conditions by eliminating the need to add a second drill steel.

Customers can choose a low- or high-pressure compressor for their drilling operation.

“Built off a proven platform and with the new single-pass capability, the DM30 II SP reduces the overall cost of production per tonne and improves transportability,” Heino Hamman, product line manager, blasthole at Epiroc Drilling Solutions, said in a release. “It offers high quality at an excellent value — and flexibility for the future.”

The DM30 II SP features a falling object protective structure cab, ground-level isolation and an airend safety shutdown system for high-temperature situations. The rig is able to continuously operate for more than 14 hours before refuelling.

The DM 30 II SP is scalable to automated features. The DM-series drill rig can be equipped with on-board technology with the optional Epiroc Rig Control System (RCS) Lite for added safety and productivity.

RCS Lite offers a number of safety and interlock features. It also provides a convenient foundation to add more functionality and technology options in the future without a major rebuild of the machine. RCS Lite allows all Epiroc rotary drills to have the same onboard display and system for consistent operator training and service.

The new drill rig is on display at this year’s ConExpo in Las Vegas.
