The crawler-mounted, hydraulic tophead-drive rig offers fast hole-to-hole drilling and a low cost per tonne through single-pass capability.

The drill rig is being showcased at CONEXPO-CON/AGG 2020, which is being held from March 10-14 in Las Vegas, Nevada, US.

Built off the same 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) drilling applications. It can achieve a clean hole depth of 11m for single-pass applications. The small footprint of the DM30 II makes it easy to manoeuvre 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 structure design life exceeding 45,000 hours. The single-pass capability allows for fast hole-to-hole drilling and low cost per tonne. Its design and layout grants quick and easy access to all major service points, simplifying maintenance.

The DM30 II SP is designed to handle 4-6.5in (102-165mm) drill pipe with a hydraulic pulldown of up to 133.4kN and a hole diameter of 140-200mm. A 36ft (10.1m) single-pass tower option increases productivity for 29-36ft (8.8-10.1m) drilling conditions by eliminating the need to add a second drill steel.

Customers can choose a low- or high-pressure compressor to create the right configuration for their drilling operation.

Heino Hamman, product line manager, blasthole at Epiroc Drilling Solutions, said: "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. It offers high quality at an excellent value - and flexibility for the future."

Outfitted with a number of enhancements to help keep operators safe on the job, the DM30 II SP features a falling object protective structure (FOPS) cab, ground-level isolation and an airend safety shutdown system for high-temperature situations. A 300-gallon (1,136L) fuel tank allows the rig to continuously operate for more than 14 hours before refill.

For increased operator comfort, the DM30 II SP features an insulated, pressurised, heated and cooled cab with tinted glass, a suspension seat, 80dBA noise level and excellent visibility. All operational functions are controlled from the driller's console, and the ergonomic layout allows operators to instantly switch from drilling to tramming for increased productivity. In addition, the electric-over-hydraulic controls are common across the DM series, making operation easy for drillers with DM series experience.

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

Built on the RCS 5 platform that comes standard on the Pit Viper series, RCS Lite offers several 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. Epiroc has sold over 100 RCS Lite systems in 17 different countries around the world.
