How Dwyka Mining Services is using Hovermap to scan and manage open cast voids

In November 2020, Emesent partner Dwyka Mining Services was contracted to assess the geometry and volume of a cavity that was exposed in a client’s open pit, following surface blasting. The void posed a significant safety risk to personnel working in the area, and to equipment.

An attempt to survey the cavity using a conventional drone-mounted LiDAR was unsuccessful because it lost GPS access.

Dwyka Mining Services scanned the void in a single 5-minute Hovermap flight and delivered high resolution data and dimensions of the void to the client, within two hours of arriving on site.
