GroundProbe launches the GML-Underground

GroundProbe has launched the Geotech Monitoring LiDAR (GML-Underground), an underground geotechnical monitoring system.

The GML is a high resolution underground convergence monitoring system that detects rock and ground support movement with sub-millimetre accuracy, combining the strengths of radar and laser.

It has been designed to be lightweight and portable, with full dome scan coverage.

“We have taken the best of radar – namely its precision – and added it to the benefits of laser,” said GroundProbe Vice President of Marketing and Technology Lachlan Campbell.

“The results speak for themselves. GML-Underground is a high resolution, sub-millimetre, full coverage system that is plug-and-play with SSR-Viewer.

“We figured out early on that radar is not the right technology for underground monitoring.

“It is bulky; it is affected by metal and mesh; and it can be subject to ‘multipath’ – a process whereby radar beams ricochet around the underground tunnel before being measured causing inaccuracies in the data.”

GroundProbe has developed existing technologies, applying its technological knowledge to increase the GML’s accuracy, speed and resolution.

It says that the GML, which utilises patented processing techniques and software, is 170 times more accurate than existing solutions.

GroundProbe Managing Director and Chief Executive Officer John Beevers said he was proud to be able to release a solution that meets customer demands.

“Since long before I joined GroundProbe, our customers have been asking us if we have a solution for convergence monitoring in underground mines,” said Mr Beevers.

“After many years of research and development, I’m proud to announce that we do.”
