Discussion on fine 3D modeling method of complex vein-type ore body
摘要
Abstract
[Objective]The simulation of three-dimensional morphology of geological bodies through 3D modeling technology can effectively reveal the spatial distribution characteristics of geological bodies.Compared with implicit modeling methods,explicit modeling methods can depict the small-scale geological structure features more accurately.However,for the large-scale and fine 3D modeling of complex geological bodies such as vein-type ore bodies with complex shapes,there are still problems such as slow modeling speed,high difficulty,and low accuracy that need to be solved.[Methods]This study,focusing on some complex vein-type ore bodies,comprehensively applied techniques such as densified constraint points,construction of ore body splitting lines,segmented modeling,and ore body stitching,to systematically conduct research on the explicit 3D modeling methods of four types of vein-type ore bodies:branched and bifurcated composite ore bodies,ore bodies with barren windows,ore bodies with intercalated rocks,and ore bodies cut by faults.[Results and Conclusion]It achieved high-precision and rapid 3D modeling of complex vein-type ore bodies,which is of great significance for the fine 3D modeling of rare and precious metal vein-type ore bodies,estimation of mineral resources,and formulation of mineral resource development and utilization plans.关键词
