The U.S. Bureau of Mines has, primarily through its contract program, used large-scale centrifuges to determine design criteria for tailings embankments. The centrifuge runs were made at two installations, the University of Cambridge, Cambridge, England, and Sandia National Laboratories, Albuquerque, New Mexico, The major problems considered were as follows: slope stability of embankments, modeling erosion and seepage, use of the phreatic surface level to ascertain the validity of centrifuge modeling, and the effects of compaction and weathering on a tailings embankment. This report summarizes the results of the four test series conducted at University of Cambridge and Sandia National Laboratories. A review of prior centrifuge applications to mining problems is included. Consideration is given to future centrifuge application to mining problems in both soil and rock mechanics.
