Abstract: The 3D modeling method has been applied in the field of field design, and its application in the coal industry is still in the exploration Thisstage. This paper takes the coal industry site design as the research object. In Throughprinciple, through the description of the application and related functional development of the GEOPAK Site ，and combined the three-dimensional site design with GEOPAK Site software applications. Then discussed the applicability and advantages of GEOPAK Site software in the coal industry；In practice, this paper takes Wang Zhuang coal mine as the research object, discussed the application of 3D modeling method in the design case of Wang Zhuang coal mine.（The Wang Zhuang coal mine as the example in this paper） and a wider range of site design work, iIn order to provide reference and help to the design of the field in the perspective of three-dimensional design. And introduce the ideas and methods of the three dimensional space design, then enrich and carry out the more widely use of this method.
