Abstract
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.关键词
