Create Sedimentological and Structural Models to Assist in Identifying Geological Features That Impact on Mining
Regional geology mapped in three dimensions from borehole data supplied by three mining groups, built for mine geologists and planners assessing seam disruption before layout design.
by Mark Grodner | December 2001
A three dimensional model of the northern Witbank and Highveld coalfield was built from more than 1100 borehole logs, with strata sorted into 13 major groupings and surface topography taken from satellite elevation data. It runs on open source visualisation software rather than a commercial package. Delays limited coverage to about a quarter of the coalfield.

Underground Trials of Seismic-counter and Goafing Characteristics in Pillar Extraction
2003
Underground trials at South African collieries of a seismic early warning instrument first developed for an Australian longwall, with analysis of how roof layers fail during pillar extraction.
What this report foundA stand-alone device was built that detects micro-seismicity within 100 m of the roof and raises an alarm when preset thresholds are exceeded, giving early...
Soil Rehabilitation: Can Dung Beetles Improve Post-mining Land-use Options?
2018
Final report of a three year study on rehabilitated South African coal mine soils, testing an invertebrate based addition to conventional rehabilitation, for environmental managers and land use planners.
What this report foundAnts, termites, dung beetles and earthworms are known to improve soil health, but none had been deliberately applied as part of a mine reclamation strategy.
