The stability of slopes in open pits: M38-8/18E-PDF

"Many open pits in Canada are currently being planned with depths of the order of 1000 ft. The competition between safe slopes and maximum profits is thus providing greater incentives than before for improving the design of these types of mines. If it is accepted that the objective of any work in rock mechanics is to provide guidance for the judgment that must be exercised in making decisions on planning and operations, then it can be claimed that within reason studies on pit slopes stability are valuable. If, however, from rock mechanics investigations definitive slope angles are desired for each pit wall, then the warning must be given that not only can this not be done for hard rocks at the present time but that it will be a difficult goal to obtain within the foreseeable future"--Introd., p. 1.
