Abstract
A boundary element technique has been developed for solving three-dimensional elastodynamic problems in rock mechanics, such as joint slip and the sudden advance of excavations. Both implicit and explicit versions of the technique have been implemented. Comparisons of accuracy and computational efficiency are made for a simple verification problem. Examples in which the technique has been used to investigate the dynamic response of supported and unsupported excavations in tabular orebodies are presented.
