Combined application of structural analysis, geostatistics and key- block theory in the study of problems of stability and reinforcement on mining works

Abstract : The study presented in this paper aims at the setting up of a methodology which allows the design of mining works, underground or otherwise, taking into account the geological structure of rock masses in which they are located. Three stages of this methodology are presented: the determination of statistical and geostatistical characteristics of the population of fractures; the generation of a field of fractures, with given statistical characteristics, by simulation; the study of the stability of isolated blocks defined by these fractures, by means of the key-block theory. Following the processing of this structural data, rules of action, concerning the conception and execution of the planned structure, will be drawn up.
