| RM 1.7K | 11.7 m | 2.4 m | 1.7 m | 21 T | 4 | 4,5 | Rotary with dust collection | "Man-in position" | Diesel/Electric | Hard rock/Non-flameproof |
Dry drilling is performed by the rotary method which has the added advantage of very efficient dust collection system. The operating controls are located next to the drilling unit, enabling accurate bolt installation - both mechanical or resin types. The operator stand is found directly by the roof bolting turret and it is protected by an adjustable, hydraulically operated, high-strength canopy.
The tooling system enables drilling of holes at 25 - 38 mm DIA. Depending on the compressive strength of the rocks, effective time of bolt installation is between 2,5 to 3min per bolt (including hole drilling time). At KGHM Polish Copper Industry, 90% of bolting process is carried out by means of Mine Master bolting rigs.
