Intra-seam Sedimentological Controls on Coal Quality: 2 Seam, Witbank Coalfield
Sub-seam mapping at an opencast colliery in the Witbank area, setting out a method geologists and resource estimators can apply to other seams.
by Mark Grodner | March 2003
Sub-seams within the No 2 Seam were characterised at a single test site using lithology, seam thickness, proximate analysis, petrography and geophysical logs, and a paleoenvironmental model was built from them. Wireline logs separated coal from interburden but could not resolve the individual zones, because the physical differences are too subtle. Better sedimentological models gave better reserve and resource estimates.

Wetland rehabilitation with Dongalock shutters
2021
Two field trials, one on a mine affected wetland and one on an undisturbed site, both built by community members, plus a desktop comparison against engineering and cost criteria.
What this report foundCompared against concrete and gabions on cost, construction time, footprint, durability and safety, the Dongalock product proved cheaper and quicker to install...

Compared against concrete and gabions on cost, construction time, footprint, durability and safety, the Dongalock product proved cheaper and quicker to install in small and medium incised valley bottom wetlands, and needs no heavy plant, so local enterprises can build it. Concrete still suits large wetlands carrying high water velocities.
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.
The Relationship Between Geological Structures and Dolerite Intrusions in the Witbank Highveld Coalfield, South Africa
2008
Structural study of dolerite dykes and sills at four collieries south of the Ogies Dyke, linking intrusion geometry to mining conditions and coal quality. For mine geologists.
What this report foundDolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield.

Dolerite intrusion mechanisms and their metamorphic effect on coal were examined across four collieries in the south eastern Witbank Coalfield. In decreasing order of importance, intrusions cut safety by raising the risk of roof, pillar and floor failure, raise mining costs, reduce saleable tonnage, and increase waste generation and environmental risk.
