Sustainability Beyond Mining: Transformations in Systems for Secondary Beneficiation
2012
Doctoral work on sustainability thinking in the mining sector, drawing on air quality and waste residue projects inside a multinational miner, for readers concerned with beneficiation of mine waste.

Sustainability in mining is still framed in neoclassical economic terms, measured by profit, shareholder value and growth, with social and environmental dimensions added in response to regulation. Six air quality and waste minimisation projects run over seven years were assessed against seven dimensions of the biosphere and fell well short. A collaborative model is proposed for a sector built on mining waste residues.
The Optimum Methodology for Conducting High Resolution, Shallow Reflection Seismic Surveys on South African Collieries
2001
Field procedure standards for high resolution seismic work over seams 30 to 100 m deep, trialled at two Mpumalanga collieries, with a cost comparison against exploration drilling.

Shallow reflection seismic surveys failed on South African collieries mainly because too little preliminary data, from vertical seismic profiles and noise spreads, was gathered before the surveys were designed. Following the field procedures set out here produces usable data for mine planning. For target depths under about 150 m, exploration drilling stays cheaper, because shot holes must be drilled below the weathered layer.
Rehabilitation of Mined Land – Soil Compaction Alleviation
2011
Final report on mined land rehabilitation trials comparing pasture species and organic amendments on compacted mine soil against normal agricultural soil, for rehabilitation and pasture planning.
What this report foundExperimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material.
R1500,00
Experimental studies tested ways to alleviate compaction on mine soils by combining mechanical treatment with organic material. Survival of 16 pasture species was recorded on mechanically ameliorated compacted soil, dry matter and leaf area were measured for tall fescue and cocksfoot at different levels of organic material, and soil fertility, bulk density and root biomass were tracked under irrigated and dryland grass.
