| 摘 要： | 将模糊灰元与矿岩稳定性评价相结合，从地下开采的角度选取能够反映矿岩稳定性的参数进行评价。在模糊物元理论、灰色系统理论和关联函数运算的基础上，建立了矿岩稳定性评价的模糊灰元模型，经关联变换及从优隶属度处理构造关联系数模糊灰元。采用求和归一法与熵值法相结合确定评价指标组合权重系数的方法，通过关联度计算和最大关联度原则，对开阳磷矿沙坝矿矿岩稳定性等级和优劣排序进行了模糊灰元评价，取得了令人满意的结果。

| Abstract: | In view of underground mining, an ore-rock stability evaluation was taken combining the fuzzy-grey-element, on the parameters that are capable to reflect ore-rock stability. Based on fuzzy-matter- element theory, grey system theory and correlation function calculation, a fuzzy-grey-element model is set up for evaluating ore-rock stability. And a fuzzy-grey-element of correlative coefficient is constructed by correlative transformation and processing the optimal subordinate degree. The combinational weight coefficient of evaluation index was decided by combining summation normalization method with entropy method. A fuzzy-grey-element evaluation was also taken on the grade of ore-rock stability and the sequence from good to bad at Shaba Fields of Kaiyang phosphorite Mine by calculating correlation and adopting maximum correlation theory. Results obtained are all satisfactory. |
