Abstract

The paper quantitatively compares predicted and encountered shear zone size and location and rock type for tunnels in the Colorado Mineral Belt. The Colorado Mineral belt is composed of igneous formations with associated metamorphic rocks and faulting. As such, it represents the most complex of provinces for at-grade predictions. Shear zone and rock type data are assumed to be statistically homogeneous because of the common geology of the seven tunnels. The conclusions indicate, among other things, that with no information about the connectivity of cross-section features between the surface and tunnel grade, correlation of predicted and encountered faults can only be statistical.
