Plan geometry and other factors relating to natural rock slope stability applied to design of De Beers mine / by D.R. Piteau.: M34-20/190E-PDF

“As part of a major study relating to the stability of rock slopes of De Beers Mine, a detailed investigation was made of the natural slopes of De Beers Mine and four other mines in Kimberley. Attempt was made to determine the controlling factors which either lead to or detract from the stability of the slopes, the main objective being to assess whether the natural breakback of the slopes would jeopardize the main railway line located in close proximity to the pit. Current theories of slope stability all deal with a slope as a two-dimensional problem, i.e. a slice of unit length of an infinitely long slope is considered for a condition of plane strain. In this the tacit assumption is made that the plan radii of the crest and toe of the slope are infinite. This is not the condition encountered in practice, particularly in open pit mining where these radii of curvature have important effects on the safe slope angles. To determine these and other effects a study was made of the slope breakback and other related factors in the four big holes of the diamond mines in the Kimberley area"--Abstract, p. iii.
