Epiroc has introduced the DM30 II SP (single pass) rotary blasthole drill for quarrying and small mining operations. The crawler-mounted, hydraulic tophead-drive rig offers faster hole-to-hole drilling and a lower cost per ton 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) drilling applications. It can achieve a clean hole depth of 11 m (36 ft) 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 mines.
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 faster hole-to-hole drilling and decreases the cost per ton. 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 - 6.5 in. drill pipe with a hydraulic pulldown of up to 30 000 lbf (133.4 kN) and a hole dia. of 5.5 to 7.875 in. (140 - 200 mm). A 36 ft single-pass tower option increases productivity for 29 – 36 ft drilling conditions by eliminating the need to add a second drill steel.
“Built off a proven platform and with the new single-pass capability, the DM30 II SP reduces the overall cost of production per ton and improves transportability,” said Heino Hamman, Product Line Manager, Blasthole at Epiroc Drilling Solutions.
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 gal. 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, 80 dBA 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 scalable to automated features. The DM Series drill rig can be equipped with onboard technology capabilities with the optional Epiroc Rig Control System (RCS) Lite for added safety and productivity.
