将地面岩土工程的工程地质稳定性分区概念引入矿山地下工程围岩的稳定性分类。在分析影响围岩稳定性条件的基础上，根据梅山铁矿的实际情况，确定了本文分区所考虑的各种因素并进行了定量化处理；简述了模糊聚类动态分级方法。在统计梅山铁矿１３７０个样本的基础上，利用模糊聚类分类法对该矿围岩进行了工程地质稳定性分区，并将分区级别与常用的ＲＭＲ围岩稳定性分类级别进行了比较，给出了其深部围岩稳定性分区结果。
The introduction of the concept of engineering geology stability zoning of ground geotechnical engineering into the stability classification of surrounding rock of underground mine project. Based on the analysis of the conditions affecting the stability of surrounding rock, according to the actual situation of the Meishan Iron Mine, the various factors considered in this paper are determined and quantified. The dynamic classification of fuzzy clustering is also briefly described. Based on the statistics of 1370 samples of Meishan Iron Mine, the fuzzy clustering classification method is used to carry out the engineering geologic stability division of the surrounding rock of this mine, and the classification level is compared with the commonly used stability classification level of RMR surrounding rock. Out of its deep surrounding rock stability zoning results.
