Abstract

This second part of the research on geomechanics and drivage support in complex geological formations was performed at the Germunde Mine and includes complementary aspects of those considered in the first part. The report includes chapters on the convergence of mining cavities, the formulation of a criterion for support design and geomechanics instrumentation. The design support criterion was established on the basis of a multiple linear correlation between convergence, geomechanical classes of the rock mass and the densities of support to be installed, and provides a useful design tool. As far as instrumentation is concerned, it was implemented to increase the geomechanical knowledge on rock mass behaviour, as well as to prove the design criterion.
