SURPAC has a complete set of three-dimensional modeling tools, and it could achieve complete imaging of mine exploration, three-dimensional geological modeling, the establishment of engineering database, open gallery and underground mine design, production and mining progress plans, tailing, and reclamation designs. Moreover, SURPAC could help metal mines to effectively achieve digitization and informatization of mine design, planning, and management.
A GOOD MESH CHARACTERISTICS IN FLAC3D SERIAL
The SURPAC serial software is a set of megadigitized mining engineering software with domestic leading level in minefields, and it is extensively applied to resource appraisal, geological measurement, mine design plan, production plan management, and reclamation design after pit closure. Development of the Model Transformation Procedure 2.1. Moreover, SURPAC could also expand its mechanical analytical ability based on its inherent functions such as data collection, storage, management, and inquiry to meet the requirements of an engineering model in prediction and decision support.
The current study takes the mine design software SURPAC with its powerful modeling function as the platform, builds complex three-dimensional models of mines, and automatically generates a FLAC3D model through data transformation to expand the application of FLAC3D into the numerical simulation of mine projects to solve the difficulties of FLAC3D modeling and to build accurate three-dimensional mining models that can improve the reliability of simulation results and give play to the computational power of FLAC3D. The numerical calculation of a large mining project often involves complicated three-dimensional geological models. Recently, only few studies have been conducted on this combination. Thus, combining the advantages of the mine design platform in modeling and that of FLAC3D in numerical calculation and analysis is necessary. But mine design is relatively independent of numerical calculation and analysis, and its function is generally limited to visualization and qualitative judgments. presented an integrated 3D geological modeling methodology for modeling and visualization of large 3D geoengineering applications.
suggested a 3D geological modeling technique (SGM) as a tool for constructing complex geological models in rock engineering, Wu and Xu used a simple plane to simulate the fault or multiple combined planes to approximate the fault, for modeling geological faults in 3D, and Zhong et al. A great progress has been made on simulation methods of complex geological interfaces and features, for instance, Xu et al. On the other hand, the geology or mine design platform demonstrates good three-dimensional modeling, and it could accurately express the spatial distribution of the stratum and the geological structure with different lithologies. But different lithologies have different mechanical features excessive simplification of the model would reduce the reliability of the numerical simulation results. Thus, engineers often use models by simplifications to approximately describe geotechnical models to solve this problem above.
However, FLAC3D is quite difficult to use for pretreatment modeling, particularly in the geological body of complicated multimedia and multiboundaries. FLAC3D could be used to examine the changing rules of the field effect of rock mass from the macrotrend and it is suitable for most engineering mechanics issues, particularly for analyzing material elastoplasticity, large deformation, rheology prediction, and for geotechnical numerical simulation of construction processes. FLAC3D (numerical calculation software) has been extensively recognized and applied for analyzing geotechnical issues. Along with the rapid development of computer technology in recent years, the numerical method along with artificial intelligence technique has become an important mean of analyzing and calculating modern engineering technologies and forecasting engineering stability and reliability.
