DRAGLINE-BENCH INSTABILITY RISK MANAGEMENT

An application of risk assessment and management in geotechnical engin eering associated with overburden excavation in surface strip coal min es is presented. A risk-assessment technique is proposed for analysis of the causative components of events that lead to destabilization of the dragline. These hazard events are introduced and, through an analy sis of a combined risk profile comprising such events, a technique is then proposed whereby an expert system is used with mine block data to manage and predict the risk of dragline-bench instability for specifi c mining locations.
