30 seconds of information – Reconciliation – stockpile volumes


30 Seconds of Info from Optiro

Everyone needs information – but as we all have precious little time to read long articles, each week we will post “30 seconds worth of useful information” on both our website and on LinkedIn for you. Please let us know if you find this as useful as we hope you will!


Stockpile volumes:  Remember that if you have a large stockpile, and particularly one which has a second layer on it, that you will need to increase the loose rock bulk density as compression will have occurred from trucks driving up on the broken rock.  You may need to increase the loose rock bulk density by as much as 30%.  It may pay to do a volume survey of a discrete area and compare this with the accurate tonnage removal (as measured off the primary crusher weightometer) to calibrate the bulk density.
