Analyses of pit slides in some incompetent rocks / D.F. Coates, K.L. McRorie and J.B. Stubbins, Fuels and Mining Practice Division.: M38-8/19E-PDF
"Twenty-two pit slides that occurred in two Canadian open pit mining properties are analyzed. Information on the results of laboratory tests of the rocks and a brief description of the geological environment are also presented. One deduction from the study is that slides seem to be predictable by using established theory. This corroboration indicates that, contrary to normal mining practice, the appropriate slope angle should vary with the height of the wall. In addition, if the general ground water level around an open pit can be reduced, the appropriate slope angles of the walls could then be increased by a determinable amount. The ultimate objective of these investigations is to determine the relationship between the percentage probability of failure of any slope designed with specific strength parameters. With this relationship it would then be possible to determine optimum slope angles"--p. 94.
