摘    要：工程岩体分级是进行矿山建设和矿山井巷围岩变形控制的基本参考依据。一般情况下通过实验取得的指标为单因素指标,按单指标对岩体进行分类只是利用了岩体的部分特征,无法全面地对一种岩体的质量进行综合评价。根据灰色关联理论,矿山岩体系统可看成是部分信息已知、部分信息未知的灰色系统;根据目前矿山岩体质量评价的基本方法,对已经取得普氏系数法、岩心质量指标法以及龟裂系数法等指标的岩体应用灰色关联理论建立了综合评价模型,并以青海某矿顶、底板岩层的实测评价指标的数据,对本文建立的模型进行了应用。值得研讨。

Abstract: Classification of engineering rock mass is the basic reference for the mine construction and engineering rock mass deformation control. Usually,the classification is based on single factor index,which is obtained by tests. But the method can only represent a part of the rock mass characteristics and can not evaluate the quality comprehensively. With gray correlation theory,the mining rock mass system can be treated as a gray system,part of whose information is known and part is unknown. Applying the gray correlation theory,a comprehensive assessment model is established for the rock mass,whose assessment indices have been achieved by Protodyakonov number method,rock core quality index method and crazing coefficient method. The new model is applied in the assessment of roof and floor rock mass in a certain mine of Qinghai province.
