To face up to the challenge of more and more demanding working conditions in the underground mines of KGHM, Mine Master has started testing of its new Face Master 1.7L drilling rig. The company says that the rig is equipped with some unique solutions, which not only significantly improve the rig operator ergonomics and machine efficiency but also allow operators to maintain optimum performance despite changeable mine conditions.

The rig features a hydraulically operated, ergonomic, “capsule-type” operator’s cabin. This cabin system as well as the front frame is certified for transmission of loads at kinematics of 60 kJ. The front operator’s window also complies with P8B according to EN-356. The cabin is equipped with air conditioning, which works both during transportation and with mine’s power grid of 500 v and is also equipped with a particle filter. Additionally, a hydrogen sulphide filter has been installed in the cabin in order to protect the operator against gas leaks, which can occur in KGHM’s headings.

The test working unit was based on an already proven design of a B40D boom and Montabert HC109 drill, equipped with water swivel and higher resistance to aggressive flushing. In order to ensure excellent traction, the rig is also equipped with a main pivot with double rotation joint (vertical with horizontal oscillation).Thanks to this solution it is possible to obtain very good stability during manoeuvering as well as to use the rig in reduced width headings.
