三维四面体网格模型在固体矿产储量估算中的研究与应用

矿体储量估算涉及到大量地质数据，传统的手工计算工作量大，计算繁琐。利用计算机以三维矿体模型为基础进行储量计算，可以有效提高矿产储量估算和管理的效率。在对当前几种常用三维矿体建模方法进行分析的基础上，选择四面体网格模型来进行矿体建模，并提出了一种基于约束的四面体网格的矿体储量计算方法。该方法的主要优点在于可以通过四面体网格模型，对矿体边界以及矿体内部品位分布等进行统一的管理，计算精度高。因此，该方法具有一定的理论研究意义和实际应用意义。

Research and Application of 3D Tetrahedral Network Model in Solid Mineral Reserve Estimation

Mineral reserve estimation of orebody involves a large amount of data, and the conventional manual computation can be a heavy and fussy work. Computing the reserve based on 3D orebody modeling can effectively improve the efficiency of mineral reserve estimation and management. Tetrahedral network model is chosen for orebody modeling after an analysis of currently commonly used 3D orebody modeling methods and an orebody reserve computing method based on a constrained tetrahedral network, proposed. The method has the main advantages of being capable of a unified management of the orebody boundary and the internal grade distribution through the tetrahedral network model and of high computing accuracy. Therefore, it is of certain significance to both theoretical research and practical application.
