"The object of the slope-stability studies at Knob Lake has been to obtain measurements in the open pits which, together with the results of laboratory tests, would permit the prediction of instability in the incompetent wall rocks. Some work is also being done in the brittle, hard wall rocks; however, only data concerning the incompetent rocks are presented here. An initial study of the slides that had occurred in the past indicated that it might be possible to determine the strength of wall rocks at any particular section by obtaining core samples that could be tested in the laboratory. Then based on the strength obtained from the laboratory tests together with some knowledge of the structural geology and using the appropriate theory, it was hoped that ultimate pit slopes that would become unstable could be identified before the slopes were created"--Abstract, p. 35. gccst Mining industry gccst Rocks gccst Soil gccst Physics Gyenge, M.
