Abstract： [Purposes]3D geological modeling technology can accurately characterize the spatial distribution characteristics of underground mineral resources by integrating multi-source geological data. However，there is currently limited research on model reliability verification when conducting 3D modeling of mines. This research systematically reviews the research progress of 3D geological modeling technology， and takes a detailed survey project of a certain mine as the research object.By integrating multi-source data，a refined 3D ore body model is constructed and validated，aiming to improve model accuracy and provide data support for later mining operations.[Methods] The main research methods employed are： ① （204 Establishing a standardized geological database based on the domestic 3DMine software platform and constructing the orebody solid model through topological connection of adjacent exploration profiles; ② Conducting cross-validation of the model using the traditional block method to assess the reliability of its reserve calculation; ③ Coupling a parametric slope bench design module to generate a dynamic evaluation model for recoverable resources.[Findings] The results show that the resource reserve estimated by the orebody model constructed with 3DMine softwareis 9.1373 million m3 ，which deviates from the result calculated by the traditional block method by 97，100m3 ，representing a relative error of 1.1% . This eror falls within the permissble range specified in the "Code for Estimation of Solid Mineral Resources/ Reserves". After optimization considering mining slope constraints， the recoverable mineral resource amount reaches 4.815 5 million m3 ，effectively enhancing the evaluation accuracy of the orebody's economic recoverability.[Conclusions] This study validates the applicability of domestic 3D mining software in complex orebody modeling and provides a technical reference for digital mine construction.
