Maptek scanners, software boosts efficiency and safety at Kirkland Lake’s Fosterville mine

Maptek’s underground laser scanners and software have been helping geology and geotechnical engineering teams save time and monitor safety at Kirkland Lake Gold’s Fosterville mine in Victoria, Australia.

At the underground mine, the geology team use two SR3 laser scanners and the PointStudio software for structural mapping and identifying structures.

“They primarily focus on scanning the ore drive development headings and then analyse the data and do the mapping in PointStudio,” Fosterville Project Rock Mechanics Engineer, Corey McKenzie, says.

The Maptek SR3 is a dedicated underground laser scanner, with a scan window of 130° vertically and 360° horizontally for capturing roofs and walls in tunnels and underground drives.

With fast accurate sensing and tailored mount accessories, the SR3 can be operated remotely from any web-enabled device and combines well with modelling software PointStudio for improving overall productivity and safety underground, Maptek says.

“PointStudio has a lot of neat tools,” McKenzie says. “Smart Query is useful for extracting joint set data, and the Distance for Objects feature can be used for fibrecrete thickness analysis.”

The geotechnical team uses ZEB scanners for convergence checks and it is, Maptek says, excited about the potential of Maptek workflows to streamline and save time in convergence monitoring.

The Workflow Editor incorporates software menu items, command line executables and scripting capabilities with Maptek Workbench tools and custom components to automate processes.

McKenzie says cloud-to-cloud comparison using laser scan data in PointStudio is all about safety.

“We want to know if the walls or backs are moving,” McKenzie said. “If we notice a spot that is starting to deform, we scan it more regularly so we’ve got that constant update of data and can track how it’s moving and the rate of deformation. We can then make decisions about rehabilitation. And we also need to know when our ground support capacity is going to be consumed.”

When PointStudio was introduced at the site this year, McKenzie found it relatively easy to learn, appreciating the visual layout of the options along the top ribbon, Maptek said.

The Fosterville geotechnical team is looking to expand its usage of PointStudio and expects the new scanline mapping tool in the latest version to help rockmass classification, according to the company.

“We’re just starting to explore the geotech/rock mechanics aspects,” McKenzie said. “Maptek is always willing to answer questions.”

The site also recently completed a trial of Maptek monitoring solution, Sentry.

“Now that we’ve tested Sentry and know its capabilities, we’ll be confident down the track if there’s an area that we want to monitor more closely,” McKenzie concluded.
