摘要(Abstract)：

选取普氏坚固性系数、波阻抗、炸药单耗和裂隙平均间距4个指标对岩体可爆性进行分级,采用层次分析法和变异系数法对4个指标进行综合赋权,避免了主观赋权与客观赋权方法在权重系数确定问题上的不足,同时建立了基于加权聚类分析的岩体可爆性分级,生产实践表明综合赋权聚类分析方法适用于实际情况。
Based on the engineering practice and the results of previous researches,four indexes inchuding the platts firmness coefficient,wave impedance,explosive consumption and average fracture spacing were selected to judge the blasting classification of rock mass.The comprehensive weight method of analytic hierarchy process and the variation coefficient method were adopted to avoid the flaws that subjective and objective weight methods used in the determination of weight coefficient.The blasting classification of rock mass was established based on weighted clustering analysis.The production practice showed that the method of clustering analysis of comprehensin weight was suitable for the actual situation.
