Review of Final Void Water Quality in Australia - State of the Art and Development of a Generic Model

Review of the Management and Impact of Mining Voids
This project, which was sponsored by 11 companies and completed in 1995, reviewed current practice and completion options for final voids to identify key issues and research requirements, and to develop a classification of void types which would aid in planning and design of mine completion. The study, which was undertaken by a research team involving CSIRO, University of Queensland, University of Western Australia and consulting personnel, identified the management of void water, long-term integrity of void slopes, waste characterisation and containment and criteria for uses of final voids as the most significant issues faced by companies.

A major outcome of the investigation was the development of a logical analysis process for determining the final completion solution for mining voids in different climatic zones. The technical information required for this analysis was defined. Inadequacies in current technical knowledge also were documented, and this provided a basis for identification of future research needs.

Review of Final Void Water Quality in Australia - State of the Art and Development of a Generic Model
Prediction of final void (pit) water quality is an important issue for both industry and government. This 1998 report, prepared by CSIRO personnel, identified the gaps in knowledge to enable the water quality in mining voids to be predicted more accurately than currently is the case.
