摘要
针对尾矿库溃坝风险评价在环境影响评价工作、实际管理工作中的重要性,应用投影寻踪动态聚类模型与尾矿库风险评价标准,并结合实例,进行定量分析。依照投影特征值进行等级判定,根据最佳投影方向确定不同指标因子对尾矿库溃坝风险的影响程度。研究结果表明,该方法不仅能给出尾矿库运行期的风险评价等级,而且对于尾矿库的普查管理能提供便捷方式,为尾矿库溃坝风险评价提供了一种新方法。
In view of the importance of tailings dam risk assessment in the needs of environmental impact assessment and practical management, the projection pursuit dynamic cluster model and the tailings risk evaluation standard were combined to conduct the quantitative analysis according to the projection characteristic value of the degrees and the optimal projection direction to determine the influence of different indicators of risk factors on the railings dam in real examples. Research results showed that the method could not only give the risk evaluation in the operation time period, but also provide a convenient way of general survey and management for tailings, which could be a new method to evaluate the dam risk as well.
