Abstract: Having systematized correlative geological data and maps of Macheng mining area,we build the 3D geological model by means of 3Dmine software,which contains the drilling database,and the ore bodies,the surface and the structure of Macheng Mining.Combining with hydro geological data of Macheng mining area,the analysis analyzes the factors that impact on ore body and infrastructure projects,which include the structure of mining area,rock crushing zone and underground water,etc.The analysis provides reliable basis for the mining design units optimizing development system,and puts forward corresponding suggestions on possible problems in future mining process,such as to strengthen hydrological changes monitoring,to avoid or plug undrilled holes,and to strengthen the support of the sidewall of the main and auxiliary shaft,etc.
