摘要

摘要: 传统的矿体建模是基于结构条件驱动的，在边界属性变化时，所建立的模型难以随之动态变化，为解决这一问题，针对矿体的动态特点，提出了基于属性驱动的矿体动态建模方法。首先利用三维块体属性模型，按任意给定的边界属性条件，在块体模型中对所需单元块体进行动态提取，然后基于特征面求取和曲面光滑算法将矿体属性模型转换成几何结构模型，最后建立给定工业指标条件下的矿体三维几何模型。应用实例表明，该方法实现了在不同边界属性条件下动态提取、生成矿体的属性结构和几何结构，可精确构建光滑矿体模型，提高了矿体动态建模效率。

Abstract: Traditional orebody modeling was driven by structure conditions. When boundary properties change, the established model was difficult to change dynamically. In order to solve the problem, a dynamic modeling method of orebody based on property-driven was presented. Firstly, 3D block property model was used to extract the required elements in the block model according to any given boundary property conditions. Then, orebody property model was transformed into geometric structure model based on the characteristic face calculation and surface smoothing algorithm. Finally, 3D geometric model of the orebody was established under the given industrial index conditions. The application example shows that the method can extract and generate property structure and geometry structure of orebody dynamically under different boundary conditions, can accurately construct a smooth orebody model and improve the efficiency of dynamic modeling of orebody.
