Mine tailings surveying accuracy with a drone survey comparison

We found that vertical offset errors of a few tens of centimeters in mine site drone surveys appear to be quite common.

To measure tailings beach lift thicknesses and slopes, and the freeboard on the tailings dikes and dam walls, the survey accuracy must be better than 15cm.

  • Are your current surveys accurate? How can you be sure? 
  • Are your current surveys consistent and repeatable or do you get different results from each new survey? 
  • Do consulting engineering companies recognize the accuracy and reliability of your tailings survey data? 
  • Does your TSF survey data pass the independent safety audits?
