摘要
三维矿床地质模型的不确定性对矿山生产决策有着重要影响,正确地对矿床地质模型进行不确定性分析可以对其本身和在其基础上所做的决策作出科学评价。矿床地质模型的不确定性主要来自于建模数据和插值方法的不确定性。通过对建模数据的产生、处理过程的分析,利用处理不确定性问题的理论和方法建立建模数据的不确定性模型。通过对建模方法产生的理论误差和实测误差进行量化,实现对建模方法不确定性的定量描述。将建模数据的不确定性和建模方法的不确定性进行叠置分析,建立矿床模型的不确定性模型。以内蒙古自治区某煤矿的地质资料为例,通过不确定性分析,建立了该矿的不确定性三维矿床地质模型。
The uncertainty of 3D geological model has an important impact on the correctness of the decision-making of mine production.Correctly analyzing the uncertainty of the geological model of a deposit can make a scientific assessment of itself and the decisions made on the basis of it.The uncertainty of the geological model mainly comes from the uncertainty of the modeling data and the modeling methods.Through the analysis of the generation and processing of modeling data,the uncertainty model was established by using the theory and method of uncertainty.By quantifying the theoretical error and the measured error generated by the interpolation method,the quantitative description of the uncertainty of the modeling method was realized.The uncertainty of the modeling data and the uncertainty of the modeling method were summed up to establish the uncertainty model of the deposit model.Taking the geological data of a coal mine in Inner Mongolia Autonomous Region as a sample,a three-dimensional geological model of uncertainty deposit was established.
