The Large Open Pit (LOP) project is an international research and technology transfer project focused on the stability of large open pit mines. It is an industry sponsored and funded program that was initiated in 2005. The sponsors comprise a diverse group of multinational mining companies, joint venture partners and individual mines. Amongst the initiatives undertaken by the LOP is the development of a series of reference books on various aspects related to the design and stability of open pit mines. The final book in the LOP series, which is scheduled to published by CSIRO in 2016, focuses on the investigation, design, operation and monitoring of waste rock dumps, dragline spoils and stockpiles. These “Guidelines for Waste Dump and Stockpile Design” are being developed by a consortium of geotechnical consultants and individuals including Piteau Associates Engineering Ltd., Golder Associates Ltd., Schlumberger Water Services, Sherwood Geotechnical and Research Services Inc., Dr. Oldrich Hungr of the University of British Columbia, and Dr. Ward Wilson of the University of Alberta.
The Guidelines are intended to help both geotechnical practitioners and non-specialists improve their understanding of the myriad of factors that can influence the stability of waste dumps, stockpiles and dragline spoils. They are intended to provide practical guidance for both designers and operators. Another objective is to define the current state of practice and establish benchmarks or standards of practice that the mining industry can use to help defend and judge the suitability or acceptability of a given investigation, design or implementation approach.
This presentation will introduce the Guidelines and briefly outline the contents of the various chapters. Highlights will include an introduction to a new waste dump stability rating and hazard classification system, and a discussion on the evolution of stability acceptance criteria.
