Project 12.2 – Land Rehabilitation Guideline for Surface Coal Mines

Four part reference covering planning, in-field implementation, monitoring and post-closure land management, written for mine planners, rehabilitation practitioners and regulators rather than as a site specification.

What this report found

Sets out good practice for planning, implementing, monitoring and adaptively managing land rehabilitation at surface coal mines, with generic rehabilitation objectives, implementation actions and suggested relinquishment criteria for each component. It updates guidance first issued in 1981 and revised in 2007, reflecting later changes to South African rehabilitation legislation.

What this report found

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.

What this report found

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.

Coal Washability Using Coal Petrography

2019

Summary of postgraduate work validating washability prediction for southern African coals by image analysis and tomography, written for geologists, metallurgists and mining engineers valuing a deposit.

What this report foundA single float sink test destroys the sample and gives one deterministic answer, so it cannot show how washability changes with particle size distribution.

What this report found

A single float sink test destroys the sample and gives one deterministic answer, so it cannot show how washability changes with particle size distribution. Simulating washability from petrographic images and tomography allows many size distributions to be tested statistically from one sample. Running simulation alongside float sink work during exploration lets the prediction error of each be compared.
