Three-dimensional Finite Element Modeling of a Cable-bolted Cut and Fill Stope.
Proc 2nd Canadian Conf on Computer Applications in the Miner Industry Cim 2:655-67
A mechanized cut-and-fill stope at the Homestake Mine in Lead, SD, was instrumented, modeled, and monitored over a 3-year period. Conventional and bird-cage cable bolts were installed in regularly spaced fans of seven to nine holes over two sections of the stope prior to mining. Visual observations suggested that the birdcage cable bolts provided more support than conventional bolts. Calibration of a finite element model with respect to rock mass elastic and strength properties required extensive computations. Implementation of a rational cable bolt model showed little difference in rock mass motion with cable bolt supports.
