Guidelines for Evaluating Water in Pit Slope Stability is a comprehensive account of the hydrogeological procedures that should be followed when performing open pit slope stability design studies. Created as an outcome of the Large Open Pit (LOP) project, an international research and technology transfer project on the stability of rock slopes in open pit mines, this book expands on the hydrogeological model chapter in the LOP project’s previous book Guidelines for Open Pit Slope Design (Read & Stacey, 2009; CSIRO Publishing/CRC Press). The book comprises six sections which outline the latest technology and best practice procedures for hydrogeological investigations. The sections cover: the framework used to assess the effect of water in slope stability; how water pressures are measured and tested in the field; how a conceptual hydrogeological model is prepared; how water pressures are modelled numerically; how slope depressurisation systems are implemented; and how the performance of a slope depressurisation program is monitored and reconciled with the design. Guidelines for Evaluating Water in Pit Slope Stability offers slope design practitioners with a road map that that will help them decide how to investigate and treat water pressures in pit slopes. It provides guidance and essential information for mining and civil engineers, geotechnical engineers, engineering geologists and hydrogeologists involved in the investigation, design and construction of stable rock slopes.

Guidelines for Open Pit and Waste Dump Closure provides a benchmark reference for geotechnical and hydrogeological professionals, and other closure stakeholders, involved in assessing and implementing the closure of open pits and waste dumps. It defines a state-of-best-practice geotechnical and hydrological pathway that reflects current industry-wide experience; considers the perspectives of the operator, regulator and community; and encompasses closure planning, design, implementation and monitoring.Written by industry experts and practitioners, Guidelines for Open Pit and Waste Dump Closure is the sixth in a series of books developed by the Large Open Pit (LOP) Project. Focused on the technical challenges related to geology, geotechnical engineering, water and geochemistry, it covers the key aspects that relate to closure of open pits and waste dumps, including planning, long-term physical and chemical stability and post mining land use (PMLU). The book also includes workflows that provide clarity on geotechnical and hydrogeological assessments relating to closure planning; definition of pragmatic objectives and measures of success; implementation and monitoring for open pits and waste dumps for closure; and how these may interact with adjacent land uses.Drawing on global lessons learned on mine closure over a period of more than 30 years, this comprehensive guide uses industry experience to set out a road map to closure and potentially relinquishment of open pits and waste dumps. It will be invaluable for mine closure practitioners, corporate planners, mine management, mining engineers and technical staff, mine stakeholders and regulators.
