Guidelines for evaluating water in pit slope stability

Guidelines for evaluating water in pit slope stability / edited by John Read and Geoff Beale.

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 tra...
