An underground mining contractor has been fined $540,000 after a rock fall at the Hamlet Underground Gold Mine near Kambalda killed a driller and injured a probationary offsider.
At the 2025 AusIMM Underground Operators Conference in Adelaide, Dyno Nobel Senior Technical Consultant Ed Wargem delivered a message that cut through the noise of technical jargon and digital disruption: sometimes, the biggest improvements in underground development blasting come not from cutting-edge technology, but from going back to basics.
In a decisive move that rewrote its approach to underground ground support, Tomingley Gold Operations has phased out twin-strand cable bolts in favour of Falcon Bolts—an innovative self-drilling, mechanically anchored system developed by Jennmar Australia.
