mining is a prerequisite for much industrial production the products of mining are necessary heavy manual work will disappear and the risk of some types of accidents and occupational diseases will disappear or be reduced, but other types of accidents and diseases will occur or increase in risk, and employment will go down.,integration of ohs into risk management in an openpit,terbrugge et al. used a risk analysis approach designed with fault tree analysis (fta) to categorize the risks associated with design problems of slopes in open-pit mines. risk categories are identified according to their consequences for workers, equipment, production, economics, various industrial operations and public relations.

jul 25, 2018 in this study, we will use simulation analysis technique combined with other rm tools for analyzing and mitigating risks of an optimization project of an open mining. using simulation analysis for mining project risk management simulation is a process of designing a model of a real system and conducting experiments with this model for the,qualitative geotechnical hazard and risk assessment,a sidewall in an abandoned open pit, and in another it is a road-cutting above a highway. the socio-economic impact of the hazard in the road-cutting is much greater than the hazard in the abandoned pit, therefore, the associated risk is greater. this example also illustrates the concept of qualitative risk analysis vs quantitative analysis.

risk analysis is an important step in the design of rock slopes in open pit mining. risk is defined as the product of the probability of slope failure and the consequences of the failure, and is generally evaluated in terms of safety and economic risk. most of the risk analysis done at,risk management geomechanics application for open,for open pit slope design (guidelines (2)), risk is defined as the chance of something happening that will have an impact on objectives. risk is often defined quantitatively in industry practice as the probability of failure (pof) times the consequence of failure, or
