Evaluation of the potential for rock bursts in mines. Phase IV: Extension of the methodology to rock bursts involving geological discontinuities

Abstract

Rock bursts, sudden and violent ruptures of bedrock, are one of the principal hazards faced by mine workers. An a priori method has been developed that allows engineers to predict rock bursts and plan safer underground excavations, but it does not adequately predict bedrock instability near major geological discontinuities. This project will rectify this situation, by developing a simple and easy method of evaluating instability near such discontinuities. The new method will be validated in typical terrain conditions.
