Virtual mine 3D roadway modeling and its application

Mass information, high dimensional expression ability of virtual mine technology in complex areas plays an important role in coal mine production. Mine 3D roadway modeling is the core to construct the virtual mine system. This paper first introduces the data source and the processing method of the roadway 3D modeling, roadway database and data structure, the design of three-dimensional modeling is proposed based on a network of roadways and cross section characteristic, researching the database of the roadway body, the gateway node, the roadway section. Then, roadway model database design and the 3D roadway modeling algorithms are proposed according to the roadway features. Finally, the 3D modeling process is given as a practical case in the end of this paper.
