Manufacturer and service provider Epiroc introduced the DM30 II SP (Single Pass) rotary blasthole drill for quarrying and small mining operations.
“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,” says Heino Hamman, product line manager, blasthole, at Epiroc Drilling Solutions. “It offers high quality at an excellent value — and flexibility for the future.”
In a release, the company says the crawler-mounted, hydraulic tophead-drive rig offers faster hole-to-hole drilling and a lower cost per ton due to its single-pass capability. Epiroc showcased the drill rig at Conexpo/Con-Agg 2020 in Las Vegas.
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. Epiroc says it can achieve a clean hole depth of 36 feet (11 meters) for 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, Epiroc says, 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- to 6½-inch drill pipe with a hydraulic pulldown of up to 30,000 pound-feet (133.4 kN) and a hole diameter of 5½ to 7⅞ inches (140-200 millimeters). A 36-foot single-pass tower option increases productivity for 29- to-36-foot 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.
Safety features include an FOPS (Falling Object Protective Structure) cab, ground-level isolation and an airend safety shutdown system for high-temperature situations. A 300-gallon fuel tank allows the rig to operate continuously for more than 14 hours before refill.
For increased operator comfort, the DM30 II SP features an insulated, pressurized, 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.
Epiroc says the DM Series drill rig can be equipped with on-board technology capabilities, for added safety and productivity, with the optional Rig Control System (RCS) Lite. Built on the RCS 5 platform that comes standard on the Pit Viper series, RCS Lite offers a number of safety and interlock features. The company says 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.
