25–27 September 2013
Sofitel Brisbane Central Hotel, Queensland
Slope Stability 2013 will provide a forum for open pit mining and civil engineering practitioners, consultants, researchers and suppliers worldwide to exchange views on best practice and state-of-the-art slope technologies. Best practice with respect to pit slope investigations, design, implementation and performance monitoring will be discussed during the symposium.
Harry was appointed Chief Executive Energy in September 2012. Prior to this, he was Symposium’s Opening Speaker Chief Executive Diamonds and Minerals from October 2009, Managing Director of Harry Kenyon-Slaney, Rio Tinto Iron and Titanium from 2007, and Chief Executive of Energy Resources of Chief Executive Energy, Rio Tinto Australia from 2004. Harry is a geologist who joined the group from Anglo American Corporation of South Africa in 1990.

ACG Event Proceedings and Training Products The trend of open pit operations mining to deeper levels has seen an increased stress environment and a greater uncertainty about the mechanical behaviour of slopes, elevating mine worker safety and productivity risks. The ACG, through its open pit geomechanics research projects, courses and training products, seeks to equip industry with advanced design and monitoring tools and state-of-the-art knowledge. 1 Slope Stability 2007 International Symposium on Rock Slope Stability in Open Pit Mining and Civil Engineering | 12–14 Sep 2007 | Perth, Australia

Winthrop Professor Phil Dight Australian Centre for Geomechancis, Western Australia
Phil has been involved with the development and design of ground support for mining applications since 1975. He was a partner in BFP Consultants until BFP was acquired by Coffey Mining. Phil has extensive consulting experience in the geotechnical aspects of the mining industry, and has worked on open pit and underground metalliferous mining problems. In 1985 he was awarded the Manuel Rocha Medal by the International Society of Rock Mechanics for his work in open pit mining and use of ground support to improve pit stability. His ground support algorithm has been adopted by Rocscience in its evaluation of ground support in phases. With Peter Fuller he undertook research into ground support in a number of AMIRA sponsored projects. Much of that early research work has now been formalised in the literature by others. Phil joined the ACG in 2008 and has since been working on stress memory effects in rocks, influence of deformation anisotropy on stability of underground openings, ground support applications and slope stability problems.
