矿山地质灾害危险性评价

摘要

矿山地质灾害危险性评价的影响因素较多，又多具不确定性和模糊性。目前对矿山地质灾害危险性评价主要采用定性的专家打分法，具有一定的主观性。基于以上考虑，在分析矿山地质灾害形成影响因素的基础上，应用模糊层次分析法(FAHP)量化了各评价因素的权重，并将该权重引入模糊综合评价，建立了基于FAHP的模糊综合评价的矿山地质灾害危险性评价数学模型。并应用此方法对陕北某矿区的地质灾害危险性进行了评价，评价结果与实际调查结果比较吻合。%In mine geological hazard risk assessment has many contributing factors, mostly with uncertainty and fuzziness. At present, the assessment mainly adopts qualitative expert marking method with a certain degree of subjectivity. In this connection, on the basis of mine geological hazard contributing factor analysis, using fuzzy analytical hierarchy process (FAHP) quantized weight of each factor and introduces the weight into fuzzy comprehensive evaluation, finally established mine geological hazard assessment mathematical model based on FAHP fuzzy comprehensive evaluation. Using the method assessed geological hazard risk for a northern Shaanxi mine area;the result is tally with empirical investigation.
