针对传统岩体质量评价方法的局限性与不足,以模糊数学为理论基础,结合层次分析法,建立了深部岩体质量的二级模糊综合评价模型。在全面分析岩体质量的影响因素后,综合选取了14个评价指标,并按照指标的层次性进行划分,同时选用正态型函数作为隶属函数,运用二级评判的方法确定评价指标的权重,对深部岩体进行评价。从而克服传统评价方法的缺陷,使结果更加合理。最后,以三山岛金矿为例,运用该模型对-555m水平的岩体进行评价分析,得出岩体质量为Ⅲ类岩体的结论,与矿山实际情况相符,验证了该方法的正确性与合理性。
Aiming at the limitations and deficiencies of the traditional rock quality assessment methods, the fuzzy mathematics is taken as the theoretical basis and the AHP method is used to establish the secondary fuzzy comprehensive evaluation model of deep rock mass quality. After comprehensively analyzing the influencing factors of rock mass quality, 14 evaluation indexes are comprehensively selected and classified according to the level of the indexes. At the same time, the normal function is selected as the membership function and the weight of the evaluation indexes is determined by the second- Evaluation of deep rock mass. Thus overcoming the defects of traditional evaluation methods and making the result more reasonable. Finally, taking the Sanshandao Gold Mine as an example, this model is used to evaluate and evaluate the rockmass of -555m level, and the conclusion that the rock mass is of type III is obtained. The result is in good agreement with the actual situation of the mine, which verifies the correctness of the method And rationality.
