Case Studies
Satellite technology has become increasingly important for the mining industry as it provides valuable data and insights for exploration, operation, and environmental monitoring. Here are four case studies showcasing the use of satellite technology in the mining industry:
Exploration and Discovery of New Mineral Deposits
In 2012, Anglo American, a global mining company, collaborated with the European Space Agency (ESA) to utilize satellite data for mineral exploration in Brazil. The project used advanced satellite radar technology to detect geological features that could indicate the presence of valuable mineral deposits, such as iron ore and nickel. By combining the satellite data with ground-based geological information, Anglo American was able to identify new target areas for exploration, ultimately leading to the discovery of new deposits.
Monitoring Mine Subsidence and Ground Deformation
In the Australian coal mining industry, satellite-based InSAR (Interferometric Synthetic Aperture Radar) technology has been used to monitor ground deformation and subsidence caused by longwall mining. For example, the New South Wales government implemented a satellite-based monitoring system for the state’s coal mining operations, allowing for continuous observation of land surface movements. This real-time information helps mining companies ensure the safety and stability of their operations, while also enabling them to mitigate potential environmental impacts.
Environmental Monitoring and Management
In 2016, the De Beers Group, a diamond mining company, began using satellite imagery to monitor the environmental impact of its operations in Botswana. The company utilized high-resolution optical imagery and multispectral data to assess the effectiveness of their land reclamation efforts and track changes in the ecosystems around the mining sites. This information allowed De Beers to make informed decisions on land rehabilitation and better manage the environmental impacts of their operations.
Infrastructure Planning and Optimization
In Canada, satellite technology has been used to optimize the transportation and logistics infrastructure for mining operations in remote areas. For example, satellite imagery and GIS (Geographic Information Systems) were employed to plan and construct a 150-km-long all-season road to connect the Gahcho Kué diamond mine with existing transportation infrastructure. By using satellite data, the project team was able to identify the most efficient and cost-effective route for the road, minimizing environmental impacts and reducing construction costs.
Sustainable Supply (Project Goldeneye)
European production and infrastructure depend on a supply of high-quality raw materials. Ensuring that the needed materials are produced responsibly in European mines guarantees sustainable supply and prevents European countries from becoming dependent upon imports from global markets. To support the development of the European mining industry through technological solutions, the Goldeneye platform integrates information from satellite produced Earth Observation Data (EOD), drone overflight sensors and on-site recorded data.
The use cases of the Goldeneye platform address the different phases of the mine’s life cycle from exploration to closure and post-closure. The applications developed in the project include mineral detection, safety monitoring, operational management, geo-hazard monitoring, and environmental monitoring. For example, in the safety monitoring application the aim is to improve the safety of the mines by monitoring the mining sites for sudden slope and ground changes as well as analysing the environment of the mines to detect any mining water leakages from their indirect influence to the surrounding nature.
The Goldeneye platform will be piloted on five mining sites across Europe.
