Fragmentation Assessment Studies for Mining
New possibilities to quantitatively compare fragmentation in blasting and caving. Listen to Principal Scientist Matthew Thurley present fragmentation measurement for an underground drawpoint and an open-pit muckpile in this short YouTube presentation.
We provide a service based on fully automated particle identification and sizing from 3D image data of your fragmented rock. We work with leading blasting researchers and coordinate with your blast design team, surveying team or third party laser scanning service providers.
Fragmentation measurement by IMV's Principal Scientist Matthew Thurley provides;
- Confidence that the fragmentation analysis is a reliable and realistic representation of the material that was visible on the muckpile at the time of measurement
- Accurate measurement of size based on 3D imaging (no scaling and perspective distortion errors)
- Reliable fragmentation analysis as key opposing errors from overlapped particles and areas-of-fines are mitigated
- Fragmentation analysis based on a solid foundation of 20 years of evidence-based research, peer-reviewed publications, products and industry prototypes
Fragmentation results of a study of six blasts in an open-pit operation have been published in the peer-reviewed IMMM Mining Technology journal, Onederra, I, Thurley, M & Catalan, A 2015, 'Measuring blast fragmentation at Esperanza mine using high resolution 3D laser scanning' IMMM Transactions. Section A: Mining Technology, vol 124, no. 1, pp. 34-46.

"Fragmentation and particle size distribution is important at our underground mine. We are particularly interested in understanding the impact of blast fragmentation in a mine-to-mill sense and LHD productivity. The automated and accurate analysis of laser scanned muckpiles has provided additional data for our material handling system and enabled us to assess blast design performance. I highly recommend IMV for assisting with any fragmentation assessment projects."
