[Job Story] The Cat MD6420B Drill Breaks the Record in Australia

Australian Wolff Mining, part of National Group, are a key supplier of heavy earthmoving equipment to the mining sector.
A milestone of 43,794 drilled meters (dm) has been reached for the month of November at the BMA Saraji Coal Mine.

For the past 16 months, Wolff Mining has been assisting BHP Mitsubishi Alliance (BMA) Saraji in a sprint drilling capacity, providing drilling equipment and full contract mining services.

Wolff Mining currently supplies BMA Saraji with a Cat M6420B Drill with GPS and provides operational labour such as supervisors, drillers, and fitters.

The M6420B is one of Cat’s heavy-duty drills designed for open pit mining, delivering reliable performance and operational safety. It is one of the favoured models by drillers around the world and encompasses leading features from the ultra-class to the mid-size rotary drill line.

Some of the advanced features available include improved fuel efficiency, electro-hydraulic controls that provide increased operator safety and precision, computer-controlled drilling, enhanced diagnostics, and autonomous ready functions.

November drilling at BMA Saraji has been undertaken in 270mm holes ranging in depth from 30m to 65+m in tertiary material.

Wolff Mining recently achieved a milestone of 43,794 drilled meters (dm) for the month of November, beating the previous record of 41,500dm at BMA Saraji.

“The performance of our Cat M6420B Drill has been exceptional” notes Mark Ackroyd, National Group Managing Director.

“It is very rare that a drilling company exceeds 40,000dm a month, so breaking the site record of 41,500dm at BMA Saraji and setting a new record of 43,794dm for the month of November is a great achievement”.

“To achieve a milestone such as this takes a highly skilled and motivated team and a high-quality piece of mining machinery such as the Cat M6420B Drill. I would like to congratulate the team here at Wolff Mining for their outstanding efforts and praise the performance of the CAT Drill” says Ackroyd.

“Wolff Mining has continued to grow from strength to strength, with an expanding team and a growing fleet of mining equipment. 2020 has turned out to be an interesting year full of surprises, but it’s no surprise that we have continued to grow even during these challenging times”.
