A method for predicting deep resources in altered zone of ore deposit based on 3D geological modeling
With the increasing demand for mineral resources and the gradual shortage of shallow mineral resources,how to effectively develop deep mineral resources has become one of the national key research topics.In the past,two-dimensional deposit information could not determine the precise reserves of deep resources,which hindered the development progress of mineral resources.Therefore,a study on the prediction method of deep resources in the altered zone of deposit based on three-dimensional geological modeling was proposed.The geologi-cal 3D modeling software(GOCAD)and computer technology are applied to build the deep geological 3D model of the altered zone of the deposit.On this basis,the optimal unit scale is determined,the deep geological statistical unit of the altered zone of the deposit is divided,the deep geological variable of the altered zone of the deposit is extracted,the weight value of the geological variable is calculated,the relationship between the deep geological statistical units is explored,and the deep resources of the altered zone of the deposit are predicted based on the 3D evidence weight method.The experimental data shows that the minimum value of the prediction error of the deep resources in the altered zone of the deposit obtained by the proposed method is 1.01%,which fully confirms that the proposed method has a higher prediction accuracy of the deep resources.
