为解决三维地质模型不确定性问题突出、精度难以评价的难题,分析了三维建模过程中误差来源,提出采用C-F方法对三维地质模型各阶段不确定性进行统一度量,以实现三维地质模型精度有效评价。以扎哈淖尔露天矿为工程实例,构建了扎哈淖尔露天矿三维地质模型精度评价体系,以解析法和模糊评价法确定了各证据的可信度,以简单有效的AHP方法确定了各证据权重,经证据的合成与传递,有效地实现三维地质模型精度定量化评价,最终确定了扎哈淖尔露天矿三维地质模型的可信度为0.783。经实际采动量核算,验证了该方法的可行性,提高了模型实际应用价值。

Abstract: In order to solve an uncertainty problem of 3 D geological model and hard evaluation of accuracy, the paper had an analysis on error sources during 3 D modeling process and provided the C-F Method applied to a unified measurement conducted on each stage uncertainty of 3 D geological model in order to realize an eff ective accuracy evaluation on 3 D geological model. Based on Zhahanaoer Open Pit Mine as an engineering case, an accuracy evaluation system of 3 D geological mo del for Zhahanaoer Open Pit Mine was established. An analytic method and fuzzy evaluation method were applied to define the each evidence credibility and the simple and effective AHP Method was applied to define the each evidence weight. The integration and transmission of evidences could effectively realize the accuracy quantita tive evaluation of 3 D geological model. Finally, the credibility of 3 D geological model for Zhahanaoer Open Pit Mine was 0.783 as determined. With the accounting of a ctual mining momentum value, the feasibility of the method was verified and the actual application value of the model was improved.
