STOPE MAPPING

WITH HOVERMAP™

Map stopes in minutes. Capture high-resolution point cloud data with no shadowing, without going near a bund or drawpoint.

Hovermap delivers a safe, fast, and easy alternative to CMS for stope mapping with its ability to fly beyond-line-of-sight in harsh, GPS-denied environments.

Geology, engineering and geotechnical teams can use the rich point cloud data from Hovermap scans to perform structural analysis, monitor drawpoints and brows, as well as calculate stope volumes and dimensions, over- and under-break.

LEARN HOW BHP ARE USING HOVERMAP™ TO MAP STOPES

BHP have been deploying Hovermap since 2017 to map their stopes at their Olympic Dam site. After implementing this technology the site has been able to inspect stopes from a safe distance whilst uncovering never seen before details including areas previously hidden by shadows.

WHY CHOOSE HOVERMAP™

FOR STOPE MAPPING
emesent-mining-safety-hovermap_icon
MAP HAZARDOUS AREAS SAFELY & QUICKLY

Substituting traditional survey methods with a drone-mounted Hovermap LiDAR scanner eliminates the requirement for surveyors to work near the stope edge, and improves data quality and coverage.

ENHANCED STOPE ANALYTICS

Hovermap can fly a mission and within minutes capture high resolution LiDAR point clouds and imagery. Analytics conducted on a rich point cloud data gives engineers greater confidence in the final stope volume for reconciliation of production tonnes or for backfill.

SAFER HANG-UP INSPECTIONS

Stope hang-ups cause unplanned delays to production and create a serious safety hazard. Attached to a tele-remote loader or a drone, Hovermap captures a clear view of the blockage and informs a targeted management approach.

ACCURATE BACKFILL MONITORING

With Hovermap’s rapid acquisition of data,engineers have access to accurate information on backfill placement, heights and remaining stope volumes.

CASE STUDY SNAPSHOT

RAPID CAPTURE UNDERGROUND

In an African underground long-hole stoping gold mine, Hovermap flew two six-minute, beyond-line-of-sight, flights to fully map an enormous (150 x 40 x 20 m) stope. Previously, this had been mapped with a CMS, from three entrances and the bottom drawpoint.

While personnel remained a safe distance from bund edge, Hovermap captured  high resolution, accurate point clouds.

CMS HOVERMAP
  • Boom-mounted CMS, three scans (top, middle, bottom)
  • Total time: 3+ hours including post processing and coordinate registration
  • Incomplete, low density point cloud
  • Stope mapped from top and middle entrances
  • Total time: 30 mins including post-processing and coordinate registration
  • High resolution point cloud

It took us only 2 x 6 minutes to cover the entire stope with over 96% coverage. It would take them over 3 hours to survey this exact same stope using traditional survey methods.Matt McKinnon,Operations Manager Unmanned Aerial Services Inc

WHAT OUR CUSTOMERS

ARE SAYING
We’ve done side-by-side comparisons between Hovermap and a boom-mounted CMS in terms of setup and scan time as well as the data quality. Hovermap was a clear winner, with the scanning flight completed before the CMS boom was even set up, and the data was far superior in terms of coverage, point density and point density uniformity. We’ve mapped stopes in 5 minutes that had previously taken hours with a CMS, requiring scans from multiple entry points.Matt MckinnonFounder and CEO Unmanned Aerial Services Inc.
Quality data has always been integral to safety and productivity in the underground mining sector. Hovermap provides an unparalleled platform to deliver this.Ashley Tibbles, Mine SurveyorRound Oak Minerals
The ease of use and operation means a wide variety of people can utilise the system. From a basic operator needing to look at a new decline face that has recently been shot, to a new stope. It's really going to help get that improved information to make better decisions quicker.Andrew RouseCEO of Digital Terrain
