Three-dimensional geological modeling can visually display and express complex geological bodies, which is conducive to showing the internal morphological characteristics of geological bodies and facilitating mine management and geological research. Taking an iron deposit as the research object, the relevant geological data in the region are collated and collected, and the data of the geological exploration line and drilling data of the production exploration line are processed by information technology. Based on the three-dimensional mining modeling software Surpac, the geological database, geological entity model and roadway model of the mining area are established. At the same time, the orebody model is established to provide the basis for delineating the effective mining boundary, and the local orebody model is established according to the model and the production exploration line data to compare and update the model. The establishment of the overall geological model provides technical support for the production and exploration process and provides guidance for the mining plan of the mine. [ABSTRACT FROM AUTHOR]

Using BIM for route selection design of urban rail transit based on GIS information is the inevitable product in the development of intelligent transportation. In order to realize route forward design based on BIM+GIS, this paper analyzes the forward design's characteristics of urban rail transit. Firstly, a structured data standard of three-dimensional environment model is proposed and the structure tree is formed. Based on the Openrail, a BIM route selection design platform compatible with multi-source data is developed to generate a standardized and structured three-dimensional environment entity model. Combined with geographic information model, route design tools are developed. Finally, the scheme's conceptual models are quickly generated based on route design results, and structured data are used to assist scheme decision. The research results show that the BIM route selection design platform can be compatible with a variety of data formats in BIM and GIS models, which meet the requirements of forward design of route selection. Standardized data can realize data sharing and improve the value of model data. BIM forward design can greatly improve the design efficiency and quality. [ABSTRACT FROM AUTHOR]
