The task faced by many large Mining Companies to quantify geographically large Tailings Storage Facilities surfaces and materials is an ever-evolving process. Quantifying material movement on facilities up to 5km x 3km with restricted access inside the walls, has it’s challenges.

​

Another obstacle involves scanning material that is <20% Reflective as such is the case where Iron Concentrate is near black.

DENADA Surveys was presented with the opportunity to improve the delivery of Lidar data over a number of clients Tailings Storage Facilities. Improving on the Aerial Lidar efficiencies that were in place at the time.

​

Items to be addressed:

• Accuracy of Deliverable

• Timing of Deliverable

• Quality of Deliverable

• And As always price efficiency

​

Health and Safety is always the largest factor to include in methodology planning and consideration of proposed solutions. Hazards always exist in the work environment. On the basis of capabilities of the 3D laser Scanner, some of these hazards can be engineered out.

​

Our Solution sat with the not new by any means, but the trusty workhorse - RIEGL's Z620.
