New and existing mining projects are benefiting from innovative approaches and algorithms to analyse and interpret geophysical borehole logging and measurement-while-drilling data to produce reliable geological and geotechnical models, improving certainty and safety and reducing financial risks.
The core problem
Reliable geological and geotechnical models are vital for safe, sustainable and productive mining operations.
Rock core data used to build these models is essential yet drill holes are expensive investments for the mining industry.
Geological and geotechnical surprises can result in significant loss of production, making it even more important to get right.
While drill cores and chips from boreholes are analysed to produce the required data, coring is expensive and often the core cannot be fully recovered.
Expert measurements while drilling
Efficient and accurate analysis and interpretation of borehole measurements during drilling operations improves geological and geotechnical certainty and, in turn, mine productivity and safety.
Borehole measurements such as geophysical logging and measurements-while-drilling (MWD) are an alternative way to extract the necessary information from boreholes, even when the core has not been recovered, maximising the benefits of drilling.
We have capabilities and unique software specifically to enhance measurement from bore-holes.
Our capabilities include:
- Borehole radar-imaging analysis
- Tomographic imaging
- Measurements-While-Drilling (MWD)
- Automated logging data analysis
- Evaluation of geological conditions, including geotechnical, ore boundaries, grade, geological hazards
The ability to convert raw borehole measurements into valuable information for fast and objective decision-making is critical for effective mine planning.
Working with our collaborators, we are improving the tools to visualise, interpret and integrate geophysical data into mine systems, maximising the benefits from borehole logging measurements.
