岩体可崩性分级研究及综合评判

Study on the Classification of Rock Mass Cavability and Its Comprehensive Evaluation

针对云南锡业股份有限公司西凹生产区,通过岩石力学试验得到研究对象的力学参数,结合工程地质调查,根据RMR系统岩体质量评价方法,得到西凹生产区不同岩体的岩体质量评价评分,在此基础上,进一步分别运用RQD值评价法、RMR值评价法对研究范围内的矿岩体的可崩性分别进行评价,对于得到的三种评价结果,利用层次分析法AHP和模糊综合评判Fuzzy理论对几种方法的分级结果进行了量化处理和权重分析,综合分析得出了合理可靠的可崩性评价结果。

For the obtained by rock evaluation method Xiho production area of Yunnan Tin Co., Ltd, the mechanical tests. Combined with the engineering mechanical parameters of the study object are geological investigation, using the RQD value and RMR evaluation method to study the ore rock mass cavability within the scope is evaluated On this basis, the comprehensively, an use of weighted average comprehensive evaluation model of AHP-Fuzzy theory is analyzed d the results show that the total cavability of rock mass belongs to grade Ⅲ medium collapse to Ⅳ easy to collapse.
