Australia-based Resolute Mining has more than just autonomy on its mind at the in-development Syama Underground gold mine in Mali. The company is also weighing up full electrification of its mining and development fleet.
Resolute has partnered with Sandvik to deliver the automation solution at Syama, with the OEM also supplying the underground fleet, which includes automated Sandvik TH663 trucks and LH621, LH517 and LH514E LHDs
Sub-level caving is expected to commence at the planned 2.4 Mt/y operation in December 2018, Resolute Chief Operating Officer Peter Beilby told IM. “We will then ramp up to full automation and run-rate production by June 2019,” he added.
Resolute has previously said one of the reasons for its choice of equipment at Syama Underground was “anticipating the logical next step in the evolution of underground machinery to battery-powered operation”.
When IM asked Beilby about this, he responded: “We strongly believe that, as well as going automated, mining is going electric.”
While the initial fleet will have some diesel loaders for development headings and diesel-powered trucks, plus drilling equipment with small diesel motors, Resolute is already scheduled to have a tethered version of the Sandvik LH414E, and, Beilby revealed, a DD422iE, Sandvik’s battery-powered electric mining jumbo.
This battery-powered jumbo, designed to drive down production costs while reducing the environmental impacts of drilling and tunnelling, is also in use at Goldcorp’s Borden development project in Ontario, Canada.
And, it appears this is just the start of Resolute’s electrification plans at the project.
“We certainly want to pursue further electrification,” Beilby said, adding: “I have no doubt that in, say, five years’ time, we will be a lot further down the track with electric mining.”
IM was speaking to Peter Beilby as part of a longer interview for the Big Data and digitalisation feature to be published in the upcoming IM November issue.
