A comprehensive 1 year study has been carried out to
evaluate and compare methods to predict the formation of acid
mine drainage (AMD) and to make recommendations on the methods
most suitable for laboratory and field use. This paper presents
the findings of this study and includes a brief description of
methods evaluated, a summary of the test results, and a
discussion on the ability of the methods to accurately predict
field behaviour. A principal conclusion made from the results of
the study is that accurate and confident prediction of AMD is not
likely to be achieved in a single test. Factors affecting the
choice of test procedures to be used for a given tailing or waste
rock are discussed on the basis of simplicity, time, equipment,
cost, ease of interpretation, and correlation with field data. In
addition, approaches to be used in the selection of AMD
prediction methods for site specific applications involving
either land-based or sub-aqueous waste deposition are outlined.Applied Science, Faculty ofNon UBCMining Engineering, Keevil Institute ofUnreviewedOthe
