municipal solid waste disposal; outcomes from his research have been<br />
incorporated in changes to environmental legislation in South Africa, and<br />
he has recently contributed to a new series of guidelines for managing<br />

Acid Mine Drainage<br />
Short Course<br />
Day 1 | 8 December 2015<br />
summary and objectives<br />
The one-day short course is aimed at mining personnel and<br />
regulators who are involved in all aspects of acid mine drainage<br />
(AMD) management. It aims to provide knowledge of the<br />
character and formation of AMD required to evaluate the<br />
potential environmental risk of AMD posed by mining, mine<br />
waste storage and eventual mine closure. While involving some<br />
relatively complex geochemical concepts, the course is presented<br />
in a manner that is fully comprehensible to non-geochemists.<br />
The characterisation of rock waste and the many factors that<br />
constrain the extent and precise composition of the drainage are<br />
discussed. The basic principles employed to prevent, recognise,<br />
and remediate AMD will be presented by means of theory and<br />
individual case studies. A series of presentations in the morning<br />
cover the nature, formation and environmental impacts of AMD.<br />
The afternoon covers the management of the AMD threat by<br />
means of prediction of the AMD potential, prevention and<br />
management of existing AMD.<br />

in Mining Short Course<br />
Day 2 | 9 December 2015<br />
objective<br />
This course is designed to develop competencies for mine<br />
geologists and engineers in the soil mechanics aspects of<br />
tailings and mine waste behaviour so that storage facilities are<br />
operated in a safe and environmentally sound way. Soil mechanics<br />
considerations relevant to underground backfilling operations will<br />
also be covered.<br />
