Abstract: In view of the existing three-dimensional mining software functions, Combined with the characteristics of underground coal mining, proposed the Underground Mine Three-dimensional Information Modeling System, Constructing "BIM" which suitables for underground mines. The system finally and comprehensively achieve the visualization, digital and intelligent work from whole strata geological modeling, underground mining system design, construction management, production management and other, to promote the three-dimensional informatization construction process of underground mine.
