Abstract: As the advance of exploration techniques and mining informatization level, three-dimensional modeling and 3D management technology of mines become hot spots. The paper expound the coal geological 3D management system which is based on the GIS platform. Three-dimensional modeling of coal mines need at least four kinds of data, including topography and geological data, drilling data, roadway data, elevation and image data. The paper introduce the processing methods of these data, and then introduce the procedure of three-dimensional modeling for five models. The five models are coal stratum model, drilling model, roadway model, mined-out areas model and surface image model. Taking one coal mine in north Shanxi province for example, the paper also describe some problems with the 3D modeling and solution methods of them.
