Research On 3D Geological Modeling Of Combination Multiple Sources Data And Reserve Calculation With Bauxite Deposits As An Example

3D geological modeling paid more attentions to the earth science experts and scholars at the beginning of the end of the twentieth century,and gradually become a research hotspot in the field of mine geology,oil and gas exploration,etc.The detailed description of the 3D geological model is the prerequisite and guarantee of the related metallogenic prediction and reserve estimation,which is more conducive to play an important role in 3D visualization technology and geostatistics.A bauxite deposit is an example in Henan Province,it solves a series of difficult problems in the 3D geological modeling.Based on the traditional modeling method,A 3D geological modeling method based on the combination of geological data from multiple sources can be improved,which can be modeled by any Exploration Project Location.Field exploration engineering network degree can accurately determine the ore body under the condition of rather smaller forms.Ore body modeling and reserves estimates in the region verify the effectiveness of the proposed method,it has certain reference significance for the same type of ore deposits.Paper based on the characteristics of the structure characteristics of the ore bodies and engineering data,the modeling process is expounded.Based on the basis of geological exploration data in the process of modeling,build the terrain surface model,the 3D orebody model,3D stratum model and 3D structure model.To reduce the geological workers have certain subjectivity in modeling process,First of all,we use multiple vertical profile to build of ore body contour line.Then 3D modeling in combination with multi-source data integration analysis,such as drilling,trenching,profile,geophysical exploration.Finally,we try to space modeling of complex orebody characteristics,such as fault,fold,termination,etc.The orebody properties model to deal with sample data,And show the internal grade distribution of ore bodies.The geological block method and geostatistics method were adopted to estimate reserves,and the different resource categories were divided into the block model.It will acheve the goals of the reserves category,reserve grade interval and reserve estimation dynamic visualization.In the last three different verification methods are used to verify the accuracy.The errors are within the controllable range.
