摘要论述岩体可爆性分级与岩石爆破性分区的区别与联系，根据矿山爆破生产需要系统分析影响岩石爆破效果的因素，对15种矿岩物理力学特性参数、节理几何参数测试与计算的结果进行线性相关性分析。分析结果表明，可以采用抗拉强度、抗压强度、密度及平均节理间距4个指标对岩石爆破性分区进行评价，建立基于加权聚类分析方法的岩石爆破性分区评价体系，同时采用综合赋权方法解决了客观赋权与主观赋权方法在权重确定问题上的缺陷。该爆破性分区已在包钢白云鄂博西矿应用，生产实践表明，分区方法科学、合理、实用。

Abstract：The difference and connection between blastability classification and zoning of the blasting compliance are discussed. According to the need of blasting operation in production，the factors affecting the result of blasting operation were analyzed；liner correlation was made on the data obtained from tests of physico-mechanical properties and joint geometric parameters of 15 types of rocks. The study results show that tensile strength，compression strength，density and average distance of joint could be used to appraise zoning of the blasting compliance of rocks. An appraisement system for zoning of blasting compliance of rocks based on weighted clustering analysis was established. At the same time，the method of decide weight comprehensively is adopted to solve the flaws in determining the weights of decide weight objectivity and subjectivity. This application of zoning of the blasting compliance of rocks to Baiyunebo west iron mine shows that this method is scientific，reasonable and practical.

Key words： rock mechanics blastability classification zoning of blasting compliance weighted clustering analysis weight decide weight comprehensively
