Mineral exploration support

Aerial surveys support mineral exploration project phases. Aerial surveys can efficiently cover large and remote areas to assess regional geomorphology to support mineral exploration projects. LiDAR can effectively penetrate vegetation to generate bare earth models to aid in mineral exploration projects. This provides the means to identify surficial expressions of geological zones that are not visible in traditional photography. Detailed topographic data obtained by LiDAR surveys can help guide ground-based exploration projects making them more efficient and lowering environmental impact risks.

Mine planning

LiDAR combined with orthophotography is an efficient tool to aid mine planning. New mines, or expansion projects, need detailed and timely topographical information to accurately cost and plan the engineering and construction phase of the mine. Terra’s LiDAR can yield relative accuracies on the order of 10cm, which is highly valuable in a mine planning project. Terra provides LiDAR data in formats directly compatible with software applications used for detailed mine planning projects.

Topographic slope models support mineral exploration as they provide a detailed tool that helps identify rock formations conducive to specific minerals.
Highly accurate topographical information allows mine planning to be carried out accurately and efficiently from the desktop. Iterations of planning can be virtually implemented in a real-world data environment.
Multiple transmission line circuits, whether high voltage or distribution lines, can be mapped and evaluated using airborne LiDAR.
Digital mapping allows mine operators to rapidly collect data and assess the existing conditions in the mine.
In order for mine reclamation to be successful, progress has to be carefully monitored. Data from mine reclamation monitoring can be fed back into the management cycle to ensure the best decisions are being made.

Transmission line

New mining operations need infrastructure. Terra’s LiDAR is relied on to generate PLS-CADD models to design or upgrade the transmission line that will provide electricity to mining operations. Terra provides data specifically formatted for PLS-CADD software used for transmission line modeling. In addition to PLS-CADD transmission line mapping, transportation routes and pipelines can also be designed or improved using LiDAR and GIS data collected from Terra’s integrated sensor array. Roadways and pipelines can also be more efficiently designed using LiDAR data.

Digital mapping

Active mine operations rely on airborne digital mapping data to effectively monitor active mining operations. Haul roads, tailings piles, benches and pit walls can be assessed for potential geohazards using digital mapping products generated from LiDAR data. Digital mapping data can be used with ArcGIS, Isatis and Vulcan software to take the guesswork out of slope stability and geohazard studies.

Mine reclamation

Mine reclamation is an important phase of a mining operation. Mine owners and engineering firms need good data to effectively decommission and remediate a mine site. Terra can provide LiDAR, hyperspectral, and digital orthophotos to support mine reclamation project phases. Following mine closure, detailed vegetation mapping can be carried out with a combination of LiDAR and hyperspectral data, which yield detailed physical and chemical characteristics of vegetation allowing for accurate monitoring of mine reclamation programs.
