Zaalklapspruit Wetland Before and After Rehabilitation

Field assessment of a wetland in the Mpumalanga coalfields, drawing on water chemistry and biological indicators, aimed at mining companies and licensing authorities.

by CSIR Natural Resources and the Environment | February 2015

What this report found

Ecological integrity of a Mpumalanga wetland affected by coal mining was assessed before and after rehabilitation, using water quality, bacterial consortium, freshwater algae and vegetation indicators. The work sits within a wider programme to give the coal sector and regulators practical ways of limiting and mitigating mining impacts on wetlands.

What this report found

Fine coal was screened at small apertures while surface moisture stayed below about 5 per cent. Above that, fines adhered to the coarser particles and screening became very difficult. The dual vibrating polyurethane mats stopped blinding and clogging, so screening area stayed available, but the screen action still could not dislodge fines from very damp coal.

What this report found

Compares labour intensive mechanised drill and blast underground mining with capital intensive bord and pillar using continuous miners, and adds the option of substituting locally made goods for imported supplies. Input data came from two mines running both types of section under comparable geological conditions, covering worker numbers, skill profiles, cost structures and import dependence, then calibrated to industry totals to drive a socio-economic model.

An Environmental Management Accounting Model for the South African Mining Industry

2008

Doctoral work comparing environmental cost practice at four South African mines and building a model from it, for environmental managers and finance staff in mining companies.

What this report foundConventional cost accounting at the mines studied could not report on physical structure or materials flow, so environmental costs such as water, energy and...

What this report found

Conventional cost accounting at the mines studied could not report on physical structure or materials flow, so environmental costs such as water, energy and consumables stayed hidden and chances to cut them were lost. Four case studies across different commodities and mining methods showed the same limitations. An environmental management accounting model is proposed to identify and allocate those costs.
