摘　　要：针对传统的地质建模中数据源的复杂性及工程、地质现象差异等困难,该文提出多元、多方法集成和多层次干预的建模思路,采用三维激光扫描技术构建矿山整体三维模型。依托ArcGIS桌面系统、GoCAD、Flac3D等软件模拟滑坡动态、岩层分布等信息。通过空间分析和数值模拟揭示其潜在信息和规律,有效地实现了数据库、三维模型、数值模拟的一致性,为数字矿山开发、建设提供一条新思路。Aiming at the difficulties exsiting in traditional geological modeling such as complex data source and the difference between geological phenomena and engineering practice, this paper put forward an idea of using 3D laser scanning technology to construct 3D mine model by multi-methods and multi-level intervention. Relying on the integration of ArcGIS, GoCAD, Flac3D and other softwares, the distribution of rock strata was analyzed, and the development of landslides was also simulated. The consistency of the database, 3D model and numerical simulation was realized, which provided an improved method for the construction and development of digital mine.
