3D Geological Model is the key and focus to learning

geological engineering

early warning and prevention of geological disasters

mine management

and other aspects that have been widely applied. 3D Geological Model involves modeling methods

data model

data structure and other aspects. Based on the comparative study on the research results of three-dimensional geological model in the domestic

it expounds the research progress in the three-dimensional model of geological field. The related modeling methods

data structure and practical application are comparative analyzed and classified

accovding to the three-dimensional geological model of the principles. The comprehensive analysis of threedimensional geological model progress is given in the article

and modeling methods

data structure

spatial analysis has done an in-depth analysis expounded. Based on a comprehensive study on the previous results

a multi-TIN and TEN mixed 3D geological model was proposed and an experiment was carried out to prove the availability of this method.
