British Sub - Committee on Tailings Dams, 2001, 145 pages.
The aim of this Bulletin (121) is to highlight and lea from some of the difficulties commonly encountered to help owners, managers, contractors and other personnel responsible for the day to day construction of tailings dams, to avoid similar difficulties. It is intended to be of help to all those connected in any way with tailings dams and waste lagoons: goverment officials conceed with regulations, planning offcials conceed about the requirements needed for planning permission, and those conceed about the continuing stability of existing tailings dams.
Examples are given of accidents and failures, together with some examples of effective remedial measures.
