ABB reported it sold a big mine hoist systems package to Newmont’s Tanami gold mine in the Northern Territory, Australia. Valued at $17 million, the contract includes the design, supply, installation and long-term support for a double-drum personnel-riding hoist and a friction hoist for the production shaft at the mine.
It also covers digital applications for safety, a programmable logic controllers control system, remote operations capability solutions, a shaft communications system and drive systems technology.
The hoists will be delivered over the course of a 90-week period.
Currently, ore is trucked to the surface, a process that constrains the planned expansion of the mine, Newmont said.
“The Tanami expansion project includes construction of a 5.4-m shaft that can reach 1,460 m below surface depth to enable recovery of ore at a depth,” Newmont Regional Project Director Neil Steyn said. “ABB’s in-house mechanical hoist design capability will help deliver a tailor-made solution in a cost-effective way.”
The expansion project is expected to increase the annual capacity of the processing site from 2.6 million mt and extend the mine life beyond 2040.
Since 1986, the remote mine has produced more than 10 million oz of gold.
