Three-dimensional Modeling Analysis Of Mine In Qinling Mountain Midland

This thesis Based on the geographical information system, Global Position System and satellite remote sensing system to analysis the Mineral exploration area, then Use the 3D geological modeling technology, complete the underground 3D geologic modeling, to achieve the rational mining of mineral resources.The "3S" refers to the information technology of Remote Sensing, Global Positioning System, and Geographical information System, Combined with the research theory of geology, to analysis the mineralized alteration of the mineral development working place, and delineating the major research boundary, guide ore prospecting, in order to give the provides of mineral resources exploitation.This thesis mainly use the satellite remote sensing ETM image, with the ERDAS software, to analysis and processing the data, to extract the mineralized alteration information, and compared with the geochemical data, to delineating the major research boundary.In this research, it completed the ETM images prophase pretreatment work first, combined with the region geological characteristics, confirmed the ETM images synthesis scheme, and using the principal component analysis, ratio method etc, to extracting mineralized alteration information, then, through the synthesis of remote sensing image, analyses the information of strata, rock and tectonic, finally, compared with geochemical data, delineating the major research boundary of working place to give the provides of the mineral resources exploitation.
