基于EVS的耦合地形–优化钻孔数据的建模方法

EVS-Based Modeling Method for Coupled Terrain-Optimized Borehole Data

摘要: 为了解决地质建模软件Earth Volumetric Studio (EVS)建立的地质模型与实际地形地貌、地层倾向不符的问题，以贵州金象煤矿为研究对象，提出一种能真实反映地形地貌与地层倾向的建模方法(EVS耦合地形–优化钻孔数据的建模法)。通过工程实例将该方法与地层建模进行对比分析，结果表明采用耦合地形–优化钻孔数据的建模方法建立的模型比地层建模方法建立的模型更能反映实际的地质情况，与勘探方法探测的地质情况也更相近，且模型误差更小。

Abstract: In order to solve the problem that the geological model established by the geological modeling software Earth Volumetric Studio (EVS) is not consistent with the actual topography and stratigraphic tendency, a modeling method that can truly reflect the topography and stratigraphic tendency (EVS coupled topography-optimized drilling data modeling method) was put forward with the Jinxiang Mine of Guizhou Province as the object of study. Comparison and analysis of this method with stratigraphic modeling and coupled terrain modeling method are carried out through engineering examples, and the results show that the model established by coupled terrain-optimized drilling data modeling method can better reflect the actual geological conditions than the models established by the above two methods, and the geological conditions detected by the exploration methods are also more similar, and the model error is smaller.
