Epiroc introduced the DM30 II SP (single pass), which the company described as a rotary blasthole drill for small mining operations. The crawler-mounted, hydraulic top head-drive rig offers faster hole- to- hole drilling and a lower cost per ton through single-pass capability, the company reported.
The rig uses the same platform as the DM45 and DML blasthole drill rigs. It can achieve a clean hole depth of 11 m for single-pass applications, the company reported. It is easy to maneuver on tight benches and simple to transport in the pit and over the road.
The DM30 II SP is designed to handle 4- to 6.5-in. drill pipe and offers a pulldown of up to 30,000 lbf-ft and a hole diameter of almost 7.875 in., the company reported. A 36-ft single-pass tower option increases productivity for 29- to 36-ft drilling conditions by eliminating the need to add a second drill steel. Customers can choose a low- or high-pressure compressor, depending on their needs.
