A regional monitoring programme was found to be viable and is proposed as a public private partnership covering air emissions, air quality and energy efficiency on the Mpumalanga Highveld. The assessment concluded that the worst health impacts fall on residential areas, driven by inefficient coal burning for heating and by housing sited close to large industry.
Cleaning Near Moving Conveyors
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.
R1500,00
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.
Can old bord-and-pillar workings be mapped from surface?
2016
Desktop review updating two earlier assessments, weighing borehole scanning, robots and unmanned aerial platforms as routes to locating old workings ahead of opencast drilling and blasting.
What this report foundNo surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics...

No surface geophysical method can map individual bords and pillars at the depths typical of the Witbank coalfield, a limit the review attributed to physics rather than to technology, since the targets are small relative to their depth and conductive layers often lie above the seam. Borehole laser scanning remains the workable option, with sonar suited to flooded workings.
