摘要
以近年来我国煤矿事故数据为基础,采用层次聚类分析的方法,对不同省(市、区)的煤矿事故类型之间的相似性进行了讨论。结果表明,用层次聚类分析的离差平方和法比较适用于事故特征的分析。本方法对我国煤矿灾害区划有一定的指导意义,为煤矿安全战略区划提供有用信息。
Based on the coalmine accident data,using the method of hierarchical cluster analysis,the similarity of coalmine accident type between different provinces( city or distinct) was discussed. The result shows that the Ward method of hierarchical cluster analysis is fit for the analysis of accident characteristics and has some guiding significance to coalmine disaster region division.
