Purpose. For modeling and resource estimating of ore deposits, an important aspect is the stage-by-stage control of the quality of performed operations, as well as the correctness of the constructed model as a whole. The purpose of this article is to analyze the methods and techniques for validating the results of each stages of three-dimensional modeling and resource estimation of mineral deposits.
Design/methodology/approach. The possible consequences of the presence of critical errors, the application of incorrect methods at each stage of three-dimensional modeling and resource estimating are considered. Methods of their identification and elimination are analyzed. It is shown by the actual example of ore deposits.
Findings. Geological objects, in particular ore deposits, are highly complex, so a model created on the basis of a limited set of data cannot be true. It should reflect the individual properties, parameters, characteristics of the object with enough sufficient to solve actual practical problems. The number of verification procedures at various stages of modeling, as well as their selection for a given object, depends on the specific features of the deposit, the modeling methodology, etc.
Practical value/implications. Based on the obtained algorithm for stagy-by-stage verification of modeling and resource estimating results, you can create an optimal set of methods for a certain deposit and the tasks to be performed.
