Abstract

Resoblok software is a powerful computing tool which allows simulation of fracturing in rock formations from actual or statistically defined data. Combined with a method of analysis of the stability of isolated blocks, it becomes a means of predicting risks of instability and enables the calculation of a suitable bolt-propping system to remedy the problem.

In general, the choice of a bolt-propping plan is made by analysing various possible alternatives. The criterion used is the minimisation of the number and size of unstable blocks, but economic considerations and complementary technical solutions (grillage and concreting) are also taken into account. The relatively simple calculation method used speeds up the analysis of stability, and permits the study of various method of bolting for various types of fracturing geometries. Application to actual situations should be carried out progressively, comparing the model results with observations and measurements in situ, as well as continuously improving knowledge of the fracturing, the mechanical characteristics, and the hypotheses of the calculation. .
