DM30: Rotary blasthole drill rig – Mid-range

Features & benefits

  • Rugged track drive and undercarriage
  • High ambient cooler and an adjustable hydraulic fan for longer component life and lower maintenance cost
  • Spacious, heated/air conditioned and pressurized cab

The DM30 is a crawler mounted, hydraulic tophead drive, multi-pass rotary drilling rig specifically designed for production blasthole drilling to depths of 90 ft (27.4 m) with a 30 ft (9.1 m) drill pipe change. An optional 4-rod carousel supports drilling to depths of 150 ft (45.7 m). Nominal diameter is 5 in to 6¾ in (127 to 171 mm). The DM30 generates a bit load force of up to 30,000 lbf (133 kN). An angle-drilling option is also available. Utilizing a diesel engine to drive the air compressor and hydraulic system, the DM30 can be configured for low pressure rotary or high pressure DTH drilling.

DM25-SP: Rotary blasthole drill rig – Mid-range

Features & benefits

  • Can drill up to 50 ft (15.2 m) in a single pass, which saves drilling time on every hole
  • Raising or lowering the tower can be accomplished in less than one minute
  • Tower pinning is performed remotely from within the operator’s cab
  • The optional angle drilling package allows the tower to be positioned up to 15 degrees from the vertical position
  • The DM25-SP can be configured for low pressure rotary or high pressure DTH drilling.

The Atlas Copco DM25-SP is a crawler mounted, hydraulic table drive, rotary drilling rig specifically designed for production blasthole drilling to depths up to 50 ft (15.2 m) in a single pass without a pipe change. Tower options are available for both a 40 ft and a 50 ft clean hole tower. The DM25-SP is ideal in soft, non-abrasive applications suitable for kelly bar drilling and angle drilling is an option.
