LiDAR offers a fast, effect and highly accurate solution and vital data layer serving many purposes over the life of a mine, including:
- Assessment of the resource’s extent and plan stripping operations to quantify development costs, using detailed digital surface models
- Planning of site infrastructure, such as access roads, plant sites and support buildings
- Supporting flood management through hydrological studies and optimising dam sites for the mine’s ongoing operations
- Supporting the design and maintenance of embankments using engineering studies derived from LiDAR data
- Building a baseline archive of the site before operations start, to record current landscape and features such as canopy definition, to support mine rehabilitation plans at the end of the mine site’s life.
LiDAR is a highly useful resource for stock-pile volume calculations. A LiDAR survey provides a more accurate volume calculation than what can be achieved by traditional surveying methods and significantly reduces the health and safety risks associated with having personnel on-site. Aerometrex can typically provide volume calculations within three days of an aerial survey.
For open cut mines, LiDAR can provide a comprehensive three dimensional model of the entire mine site. Engineers and project managers can utilise this model to monitor the site through time and show how the mine has expanded, providing an important historical perspective and prove to be an asset when it comes time for site restoration.
