Abstract
In this paper, to update the orebody model based on the given interpreted geological information, we present a local dynamic updating method of the orebody model that allows the interactive construction of the constraint deformation conditions and the dynamic updating of the mesh model. The rules for constructing deformation constraints based on the control polylines are discussed. Because only part of the model is updated, the updated mesh is effective and the overall quality is satisfactory. Our main contribution is that we propose a local dynamic updating method for the orebody model based on mesh reconstruction and mesh deformation. This method can automatically update a given 3D orebody model based on a set of unordered geological interpretation lines. Moreover, we implement a deformation neighborhood region search method based on the specified ring radius and a local constrained mesh deformation algorithm for the orebody model. Finally, we test the method and show the model update results with real geological datasets, which proves that this method is effective for the local updating of orebody models.

Summary
To enable the use of digital and intelligent mine processes, model data are used as a basis to construct 3D geological models. This plays an important role in the entire life cycle of mine development, such as mineral deposit exploration, feasibility analysis, mining design, mining planning, production process management, etc. Orebody modeling is a dynamic process that is gradually refined with the continuous enrichment of geological exploration data. It should be modified and updated gradually along with exploration and excavation. Local resource models become outdated rapidly as geological information is collected along veins. Short-term models need to be rebuilt regularly to improve the modeling quality and optimize the long-term planning
