For the evaluation of mineral development projects, it is imperative to consider the risks involved in mineral exploration and development and to bear in mind that an adjustment for these risks is a common practice which implies raising the minimum discount rate. A company may for instance use...

This thesis addresses the problem of designing roof support systems in coal mines. When designing the roof support, it is necessary to account for the uncertainties that are inherently exist within the rock mass and support elements. The performance of a support system is affected by these...

The study that is described in this thesis deals with stope support design from a rockmass stiffness approach. Three models were developed and combined into a single one in the third part of the study in an attempt to describe and quantify the stop support and rockmass interaction. The first...
