Abstract: 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.
