| 摘 要： | 根据丰山铜矿北缘采区的矿体赋存条件及开采特点，综合国内外矿岩稳定性分类的方法，提出了以岩体质量指标、单轴抗压强度、岩体完整性系数、节理间距和节理状态等5项指标评定该采区矿岩稳定性的指标体系，并应用灰色定权聚类法对矿岩的稳定性进行了综合分级，分级的结果符合工程实际。

| Abstract: | In light of the existing conditions of the orebody and the characteristics of the mining technology in the north rim mining area of Fenshen Copper Mine and by synthesizing the domestic and foreign stability classification system of ore/rock mass, this paper puts forward a parameter system including such 5 parameters as rock quality designation (RQD), uniaxial compressive strength, perfection coefficient of rock mass, joint spacing and joint behavior for assessing the stability of the ore/rock mass in the mining area, and carries out the synthetic stability classification of the ore/rock by grey fixed weight cluster analysis. The classification results are suitable for the practical engineering. |
