- Acid mine drainage detection in receiving water bodies — Multispectral indices sensitive to iron-hydroxide precipitation, turbidity and pH-correlated colour shifts can flag acid mine drainage in rivers and lakes at 10–30 m resolution. Detection is indirect: satellites see optical proxies, not pH meters.
- Conflict-minerals supply chain monitoring via site activity tracking — Satellite SAR and optical imagery can track pit expansion, track formation and equipment presence at artisanal 3TG mining sites, giving compliance teams verifiable, dated evidence to meet EU and US due-diligence obligations.
- Dust plume and particulate emission tracking from mine operations — Satellite sensors detect fugitive dust from haul roads, blasting events and tailings surfaces using aerosol optical depth retrievals and visible plume mapping. Daily synoptic coverage from MODIS and VIIRS tracks regional transport; Sentinel-2 and Planet resolve individual source areas.
- Hyperspectral mineral mapping for exploration targeting — Spaceborne hyperspectral sensors resolve mineral absorption features invisible to broadband cameras, mapping alteration halos that guide drill-targeting for porphyry copper and epithermal gold systems.
- Illegal and artisanal small-scale mining detection — Freshly disturbed laterite and turbid river plumes leave unmistakable spectral fingerprints in open satellite archives. Sentinel-2, Landsat and Planet imagery, read together, can date the onset of illegal ASM activity and track its spread week by week.
- Mine production activity inference from truck and equipment counts — High-revisit optical and SAR imagery lets analysts count haul trucks and excavators to estimate ore throughput before any disclosure. Production slowdowns, surges and idle periods become visible days or weeks ahead of official reporting.
- Mine rehabilitation and vegetation recovery verification — Progressive mine rehabilitation is a legal obligation, but ground inspection is slow and intermittent. Multi-sensor time series from Sentinel-2, Landsat and GEDI lidar can verify genuine vegetation recovery against approved plans, season by season.
- Night-light intensity monitoring of remote mining camp activity — VIIRS and commercial low-light sensors detect radiance from remote mining camps nightly, giving operational-status signals where cloud and access deny conventional observation. Radiance is a proxy, not a headcount, and flare contamination is a real problem.
- Open-pit mine expansion monitoring — Multi-temporal very-high-resolution imagery reveals whether an open-pit mine is growing within its permitted boundary, by tracking bench cuts, haul-road extensions and waste-dump spread across successive satellite passes.
- Quarry volumetric change detection using stereo and SAR DEM differencing — DEM differencing from stereo optical and SAR acquisitions converts elevation change into cubic-metre volume estimates per reporting period, giving quarry operators, regulators and royalty auditors an independent production record.
- Structural geology and lineament mapping for mineral exploration — Satellite SAR, optical and elevation data expose fault traces, dyke swarms and lithological contacts across terrain that would take field crews years to walk. The method builds structural frameworks that sharpen drill-target selection, with honest limits on depth projection.
- Ground subsidence mapping over underground mines — InSAR time-series analysis turns Sentinel-1 and ALOS-2 radar archives into precise maps of surface subsidence above longwall, block-cave and room-and-pillar workings, detecting displacement rates and spatial extents that ground-based survey networks routinely miss.
- Tailings dam surface deformation monitoring with InSAR — Interferometric SAR detects millimetre-scale surface displacement on tailings storage facility embankments, providing early warning of precursor deformation weeks or months before visible distress. Sentinel-1 supplies the long archive; ICEYE and Capella add resolution and revisit where it matters most.
- Thermal anomaly detection for spontaneous combustion in coal stockpiles and waste dumps — Spontaneous combustion in coal stockpiles and waste dumps is a safety, financial and air-quality hazard that conventional inspection misses. Thermal infrared satellites detect the surface expression of subsurface heating before visible smoke appears.
