Introduction of Probabilistic Risk Assessment Approach to Analyze the Safety of MVS

AbstractBased on the definition of safety assessment, the safety assessment of mine ventilation system index system is established in this article, and to assess the safety of MVS with the introduction of probabilistic risk assessment (PRA) method. There are some problems such as index of performance difficult to quantify and weights are not easy to given always exist in the safety assessment of MVS, so the paper application of triangle fuzzy with hierarchy analysis theory, which solve the fuzzy for experts to evaluate hierarchy indexes, and makes the evaluation for the safety of MVS fit facts more, at last, the paper explains the method and steps
