Cleaning Near Moving Conveyors

J Maaren

2011

First phase of a two part investigation into conveyor cleaning practice at South African coal mines, covering the legal position, current mine practice and available machinery.

What this report foundConveyance legislation promulgated in 2008 and enforced soon after left the coal industry without a lawful way to clean near and under running conveyors.

What this report found

Conveyance legislation promulgated in 2008 and enforced soon after left the coal industry without a lawful way to clean near and under running conveyors. The first phase defined the problem, recorded the cleaning practices mines already use successfully, and built a structured database of mechanised platform options worth pursuing. High risk areas remain drives, take ups, snub and tail pulleys and transfer points.

BCI Chemical Research & Analysis – Calcium & Magnesium

Jacques Magliolo

2012

Desk research on two mine water by products, closing out the economic analysis behind proposed brine treatment plants, for readers judging whether recovered salts can be sold.

What this report found

Prices for calcium and magnesium sulphate are recorded for South Africa and for world markets as at mid 2012, together with price trends and the groundwater chemistry that governs which salts a mine water stream will yield. The figures were assembled to support feasibility studies on a eutectic freeze crystallisation plant and an ion exchange plant.

Petrochemical Characterization of Dolerites and Their Influence on Coal in the Witbank Highveld Coalfield, South Arica

Johannes Jochemus du Plessis

2008

Masters study of dyke and sill intrusions at collieries in the Witbank and Highveld coalfields, using thin section petrography and X-ray fluorescence, for exploration geologists.

What this report foundDolerites in the study area differ in mineral content, geometry, thickness, grain size and degree of alteration.

What this report found

Dolerites in the study area differ in mineral content, geometry, thickness, grain size and degree of alteration. Plagioclase textures indicate fractionation at different depths in the crust for the Witbank and Sasolburg intrusions, and the olivine content points to separate magma sources for two of the sills. Fine crystalline dolerite, including chilled margins and bifurcations, alters most readily.

Multi-client Aeromagnetic Data Merge & Interpretation – Witbank Coalfield

S.J. du Plessis

2005

Merged magnetic coverage and dyke interpretation across most Witbank mining and exploration ground, delivered as maps and GIS files for geologists planning around intrusions.

What this report foundGovernment and industry aeromagnetic data over the Witbank Coalfield were merged into one set of maps and GIS compatible files, and roughly 1200 dyke traces...

What this report found

Government and industry aeromagnetic data over the Witbank Coalfield were merged into one set of maps and GIS compatible files, and roughly 1200 dyke traces were interpreted from them. Purchase of a 200 m line spacing government survey removed the need for infill flying. One participating company valued advance knowledge of a single underground dyke at about R15 million.
