EMESENT HOVERMAP LiDAR SCANNING: Engineering Design Optimisation

Client quote: “This saved us millions of Rands: not having to slipe after we had erected 90% of the steel.”

Challenges:

Siyanda Bakgatla Platinum Mine (SBPM) requested a solution to quickly optimise their 3D design models for planned engineering construction work. 3D information is used to determine areas that require sliping (i.e. removal of in-situ rock from the sidewall, hanging wall or footwall) along old material declines at three operational shafts before emplacement of the conveyor belts’ steel structure.

A solution was critical as sliping after emplacement could damage the steel structure, is time-consuming and would carry additional costs for SBPM. 

Solutions:

Hovermap walking scans

Dwyka Mining Services (DMS) used our Hovermap LiDAR solution to conduct a series of walking scans on-site with the versatile Hovermap unit mounted on a backpack (see Figure 1). The total distance of scan work done was over six kilometres.

Results:

The 3D data from the Hovermap scanner assisted SBPM to promptly and accurately optimise their original 3D engineering design models, and avoid the risk of having to slipe after the emplacement of the steel infrastructure. This data enabled planning around the duration of sliping and for making the necessary adjustments to project schedules and the estimation of sliping costs.
