摘　　要：为有效解决露天煤矿三维地质模型精度评价中各项评价指标赋值主观性强、计算精度差的问题,在综合分析影响三维地质模型精度的主客观因素基础上,采用基于变权系数的模糊综合评价方法,对伊敏露天煤矿三维地质模型精度进行了评价。结果表明:评价等级为“较高”,三维地质模型计算结果与实际采出量校核相对误差在4%以内;此方法能够准确地评价三维地质模型精度。In order to effectively solve the problem of strong subjectivity and poor calculation accuracy of various evaluation indicators in the accuracyevaluation of 3D geological model in open-pit coal mine,on the basis of comprehensively analyzing the subjective and objective factors that affect the accuracy of 3D geological model,a fuzzy comprehensive evaluation method with variable weight coefficients is proposed to evaluate the accuracy of 3D geological model of Yimin Open-pit Coal Mine.The results show that the accuracy evaluation level of the 3D geological model is determined to be"higher";the calculation results of the 3D geological model with the actual recovery the relative error results are within 4%.The results indicate that this method can accurately evaluate the accuracy of 3D geological model.
