基于地质体产状特征及建模数据特点的三维地质建模方法探讨——以安徽月山矿田为例
3D geological modeling based on the occurrence of geological bodies and data characteristics: a case study from Yueshan ore field, Anhui
摘要
Abstract
Based on the GoCAD software,this paper studies the 3D modeling methods for geological bodies with different occurrences and data sources from Yueshan ore field. Ore bodies with steady occurrence are modeled based on the profile data by Section-TIN method Besides,the ore bodies simulation is based on cross-section data by the method of Splitting Surface and Optimization under multi-source data constraint. Based on multi-source terrain data,for the topography modeling with stable normal direction,the TIN subdivision on point set under boundary constraints is used. For the normal stable strata and faults,based on the profile data,the models, constructed by Section-TIN method,are merged and optimized under the topography constraint. For the intrusion with branches,based on the cross-section data,the initial surface is established by Section-TIN method and Parallel Sets of Curves method,and the model is optimized under the local constraint of multi-source data. The models can highly match the original data,as they are smooth and realistic. The methods developed provide reference for the geological body modeling with diversified distribution characteristics and multi-source data.关键词
