Assessment of the European bucket-wheel excavator technology Mine Visits-May 15 to May 31, 1982

"The rising demand for Canadian coal and depletion of shallow deposits, most suitable for surface mining, result in rapidly increasing volume of waste materials which have to be moved by the coal mining industry. While at present this challenge is being successfully met using conventional mining methods, in the future, innovative methods must be considered if Canadian coal is to remain competitive.The need for more efficient mining methods is also faced by the oil sands industry to assure competitiveness of the synthetic oil price.A look at the world mining practice indicates that large volumes of material can be economically mined and moved by the continuous mining systems comprising bucket-wheel excavators, belt conveyors and stackers. To assess the state of art and applicability of this mining method to Canadian conditions, the field trip was organized by the Department of Mining Engineering o f the University of Alberta, to several typical mining operations in Europe. It is in Europe where the continuous mining methods were developed and are almost exclusively used in large-scale surface mining."
