Maptek launches new underground mine scanners

Maptek has released new laser scanners for underground mines.

The updated I-Site 8200 laser scanners feature new tools and compatibility with Maptek Sentry surface tracking and Drive continuous survey systems.

The I-Site 8200SR has been developed for cavity surveys.

It features a carbon fibre boom that extends up to ten metres into a tunnel or over a void, while the 500-metre range scanner can also be used for surface applications such as stockpiles, shed and silo scanning.

The I-Site 8200ER has a longer range at 750 metres and provides the best outcomes for mapping underground drives and tunnels as well as surface stockpiles.

A new backsight workflow allows survey resection by triangulating three coordinated targets to find the current real world position of the scanner.

Maptek chief executive of global operations Peter Johnson stated that  Sentry is compatible with the latest I-Site laser scanners.

“Sentry combines laser scan data with sophisticated software to track and analyse surface movement over time. Any movement can potentially lead to failures, so early warning is vital,” he said.

He went on to state a major focus in the development of the system was “researching ways that Sentry could function in low light, which led to development of an intensity-based grayscale image”.

“This benefits our underground customers as well as improving visibility for open pit applications at night,” Johnson said.

“Another great feature of Sentry is it provides absolute tracking. You can take the scanner away to perform another task and return it to the Sentry setup without having to start measuring from scratch,” he said.

The Sentry update includes a rollback feature for easier data analysis.

The I-Site 8200 series laser scanners are also compatible with I-Site Drive for continuously surveying from a moving vehicle.

Johnson said I-Site scanners helped with site safety through Sentry as well as providing conformance reporting using I-Site Studio, Drive and PerfectDig. L

aser scanning provides a flexible solution for general survey and volumetric tasks, and the point cloud data can be used in geological face mapping and geotechnical analysis.
