Hydraulic Transport and Storage of Extractive Waste

Mike Cambridge graduated with an honours degree in civil engineering from the University of Surrey in 1970 and has been engaged in the planning, design, construction, monitoring and closure stages of extractive waste facilities throughout the world for more than forty-five years.  In 2002 he founded Cantab Consulting Ltd, an independent mining and environmental consultancy established to provide specialist services to the minerals and water industries internationally.  He is a Fellow of the Institution of Civil Engineers, of the Geological Society and of the Institute of Quarrying and holds current appointments as an All Reservoir Panel Engineer under the UK Reservoirs Act and as Competent Person under the Mines and Quarries (Tips) Act 1969.  He has been actively engaged in Europe in the development of the Extractive Waste Directive and subsequent guidance documents, and is the Convener of the CENTC396 “Earthworks” working group currently preparing the European Standard on hydraulic fill.  In addition, he has authored numerous papers on technical and environmental aspects of mining, quarrying, dam engineering and waste disposal.  He is currently retained as the independent inspecting engineer for both statutory and compliance purposes for the inspection, auditing and reporting on mining projects and tailings management facilities in particular, with respect to safety, stability and environmental compliance.
