Abstract:

Displacement discontinuity methods for stress analysis, pioneered by Starfield and Crouch (see, for example, Starfield and Crouch, 1972; Crouch, 1976; and Crouch and Starfield, 1983), have found wide acceptance in the application of stability assessment and design in underground mining. The presentation describes case examples where both two- and three-dimensional displacement discontinuity analysis has been used in conjunction with observations in the mines to form engineering judgements on safe layouts and recommended dimensions.
