Webinar: Achieving Greater Data Collection Levels, Faster, for Longhole Stoping

Mine Survey Plus was engaged to assist at the longhole stoping operations of a narrow vein, open stope gold mine located in the Kalgoorlie region of the Western Australian Goldfields. Underground stope scanning is used to ascertain the volume of rock blasted and removed for broken stocks, haulage tonnes, overbreak and underbreak, dilution, and other reconciliation calculations. However, the current collection method, CMS scanning, can require multiple setups and frequently produces shadowing.

Watch this recording to hear from Carl Johnson, Project Surveyor at Mine Survey Plus, how they:
  • Have sped up underground data collection by eliminating multiple total station coordination
  • Are capturing a complete, shadowless dataset from the stope
  • Are producing greater reconciliation accuracies
  • Have better mine emergency plans thanks to better void shapes
  • Are helping to improve efficiency by collecting entire stope data in one survey
