A new approach to underground excavation design at INCO's Manitoba Division was undertaken by incorporating ground and support monitoring, and numerical modelling into an empirical framework. / In the first phase of the study, a field measurement geomechanics guideline was developed for the Manitoba Division. Work in instrumentation led to the development of a new cable bolt monitoring device by INCO Ltd. and McGill University. This device has the ability to measure cable bolt performance reliably and at a low cost. As a result, a cost efficient and effective program is being implemented to monitor cable bolt layouts representatively. / The second phase of the project utilizes the computational power of numerical modelling to aid mine design of stope backs. Results from numerical modelling, presented in the form of stress signatures, suggest that there might be a correlation between back surface stability and calculated values of major and minor principal stresses. / By adding the tools of numerical modelling and instrumentation to traditional rock characterization data, a new data base for empirical modelling is established. The continual expansion of this database will lead to a more comprehensive approach to stope back design in the future.
