摘　　要：针对地下采矿工程岩体质量评价问题,基于集对分析理论,建立了工程岩体质量评价的集对分析模型。将该模型应用于佛子矿104号矿体3个水平中段岩体,选取岩石单轴抗压强度Rc、RQD指标、岩体完整性指数KV、节理条件S和地下水状况W5项指标构建五元联系度集对分析模型,对其进行质量评价。研究表明:集对分析法评价结果与RMR分类结果具有较好的一致性,且能够直观地反映待评岩体与各等级标准的贴近程度,由此证明该方法用于地下采矿工程岩体质量评价是合理可行的。A model of undergr6und engineering rock mass quality evaluation is built by making a Set Pair of the evaluation indexes and standards based on Set Pair Analysis. The model is applied to three levels of 104th orebddy in Fozi Mine. Some factors such as rock uniaxial compressive strengthen, rock quality desig- nation, integrality coefficient of rock mass; 2ointing condition and groundwater condition are taken to constitute a SPA modei with five basic connection degrees. The research show2 that the l2esuit2 of SPA are in good agreement with RMR system, reflect the closeness between rock mass to be evaluated and gi-ade standards. So, it＇s reasonable and feasible to apply this method to evaluate quality of engineering rock mass in underground mining,
