ROCKRay provided an underground mine in South Australia with mechanical rock property data to build high granularity block models.
In 2019, an underground project study team in South Australia was looking for new ways to improve rock strength estimates because standard lithological domaining techniques produced typically high standard deviations of 20-50%.
As per standard industry practice, rock testing costs limited the granularity and variability captured in the block model to the scale of 16 lithological domains.
Mining and geotechnical engineers involved in the study required reliable estimates of rock properties for mine design, ground support design, numerical modelling and fragmentation modelling.
Each of these studies required reliable estimates of the mechanical rock properties including:
ROCKRay by PETRA Data Science was the chosen solution as it was capable of filling in laboratory rock testing results along untested lengths of core and enabled the team to estimate rock testing results at the block model scale. Using optimised data fusion and machine learning it promised to:
The ROCKRay implementation project was complete within six weeks and enabled the project study team to build high granularity 3D block models by providing them with a 190 fold increase in the amount of core length with rock strength estimates available for engineering design and 3D orebody modelling.
Before implementing the machine learning software, the site had approximately 30 metres of rock sample laboratory test results for 16 lithological domains from 28 holes.
After using ROCKRay the team had access to 5690 metres available for 3D block modelling.
This meant the study team had block model scale estimates of rock strength that were significantly more accurate than the lithological mean, as seen in the error comparison chart below.
