Spaceborne Mine Waste Mineralogy Monitoring in South Africa, Applications for Modern Push-Broom Missions: Hyperion/OLI and EnMAP/Sentinel-2

Remote sensing analysis is a crucial tool for monitoring the extent of mine waste surfaces and their mineralogy in countries with a long mining history, such as South Africa, where gold and platinum have been produced for over 90 years. These mine waste sites have the potential to contain problematic trace element species (e.g., U, Pb, Cr). In our research, we aim to combine the mapping and mon...

Spaceborne Radar Interferometry for Mine Subsidence Monitoring in Australia

Land surface deformation can be caused by underground mining activities. The maximum subsidence normally occurs directly above the location of the excavation of the coal seam. In the case where the longwall mining technique is applied, the magnitude and shape of the subsidence bowl are constrained by the longwall structure (pillar). This paper describes the use of satellite radar interferometry...

Virtual reality for mine safety training in South Africa

The need for improved worker safety training programmes, as a means to reduce accidents in South African mines, is being emphasized by all industry stakeholders and driven by legislation1. Accident statistics (cf. Table I) highlight the need to address falls of ground as the primary safety hazard in underground (gold) mining operations2. The high incidence of accidents and fatalities in the Sou...

Method for quantifying image quality in push-broom hyperspectral cameras

We propose a method for measuring and quantifying image quality in push-broom hyperspectral cameras in terms of spatial misregistration caused by keystone and variations in the point spread function (PSF) across spectral channels, and image sharpness. The method is suitable for both traditional push-broom hyperspectral cameras where keystone is corrected in hardware and cameras where keystone i...
