What this report found

No operating full scale frictional ignition test facility was found anywhere in the world, and building one was judged expensive, impractical and unlikely to justify its cost against laboratory scale testing. Effort should instead go to small scale laboratory equipment using South African rocks, and to expanding geological data such as silica distribution and petrographic analysis.

Models for Predicting Methane Gas Release from Coal Seams

2005

Emission factors and calculation models for national greenhouse gas reporting, built from mine seam gas measurements and ventilation sampling, for environmental staff and inventory compilers.

What this report found

Emission factors derived from measured South African seam gas data give simple models for methane released by underground mining, surface mining and coal after mining. Applied across the industry they put total methane emissions at 52 000 to 93 000 tons a year. The models follow the IPCC Tier 2 approach using country specific factors.

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.
