Research On 3D Geological Visualization Modeling Of Metal Mines Based On Surpac

The expression of the three-dimensional spatial distribution of geological bodies and their details can play a guiding role in the production of mines and related engineering design.Three-dimensional geological modeling can intuitively display and express complex geological bodies,which is conducive to showing the internal morphological characteristics of geological bodies,and can express the relationship among various strata of geological bodies.Accurate description of the internal characteristics and spatial relationship of geological bodies is conducive to the design and mining of mines,and plays a certain reference role in the continuous revision of mining schemes.At present,in the process of mine design,when some mines express the three-dimensional model of geological body,there is a problem that only the ore body is expressed,but not the geological body of the whole underground environment is described,which makes the model lack integrity and comprehensiveness.Therefore,it is very important to establish the three-dimensional model of each part of the whole geological body and then completely describe the information of the geological body.Taking the geological body of a metal mining area as the research object,based on the collection and collation of a series of geological exploration line data,production exploration line data,borehole histogram and hydrogeological report data in the area,the geological database of the study area is constructed by using the three-dimensional modeling software Surpac.Then the three-dimensional visualization model of geological body is established,including surface model,stratigraphic model,ore body model,fault model and roadway model.Secondly,the coordinates of the stratigraphic pinch-out point on the fault are estimated by the completed model data.The virtual borehole is added at the pinch-out point,and the stratigraphic model and the orebody model are established again.The orebody model established successively is compared to verify the accuracy of the model.Finally,the block model of the whole geological body is established,and the block model of the ore body is assigned by the distance power inverse ratio method to construct the grade model of the ore body.The model can effectively show the various information of the geological body and show the geological morphological characteristics of the study area,especially the threedimensional model of each stratum,which can make the spatial structure of the geological body very clear.The introduction of virtual drilling improves the accuracy of the model,enriches the corresponding data,effectively controls the boundary of discontinuous layers of geological body with faults,and makes each stratum model of geological bodies closer to the real position.It also improves the accuracy and visualization of three-dimensional geological model expression,and can guide the relevant production and survey work of mines.The construction of block model and grade model provides reference data for the calculation of iron ore reserves in mines,安and expresses the internal characteristics and various attribute information of geological bodies.The establishment of block model makes the three-dimensional model of geological body complete.Figure 43;Table 6;Reference 54...
