3D Geological Modeling And Quantitative Prediction Of Zou-Jiashan Exploration Area In Xiangshan Uranium Ore-field

Xiangshan basin is an important uranium metallogenic Basin that the volcano rock type of domestic,provides abundant uranium resources for the country,ZouJiashan exploration area is the largest reserves of uranium deposits in Xiangshan basin,since 60 s,have a lot of geological studies about Zou-Jiashan uranium resources area,but based on two-dimensional geological survey.In recent years,the shallow ore bodies in the study area have been exploited and utilized,and the prospecting technology is deficient in the deep,the increasingly serious mine crisis.The author will prediction the resources of the deep and periphery by through the 3S technology,and based on the platform of SKUA,relying on mineral exploration theory,metallogenic theory and mineral prediction theory,combined with the geotectonic background and metallogenic geological conditions of the exploration area,using geo-statistical analysis.In the process of studied,the collection of the known data in exploration area,included exploration line profile,drilling data,middle mining engineering plan and integrate geological map,electrical prospecting section,alteration information,UAV aerial remote sensing data,differential treatment according to different raw data.To establish the uranium geological information database,the use of digital tools(MapGIS and CAD)were the vector.The process using profile frame modeling,modeling in SKUA software platform,combined the occurrence and shape of the distribution of information,with the existing the strata,rock fracture data establish the three-dimensional model of the exploration area.In the process of modeling with the study of the regional geological background,metallogenic regularity and geophysical and geochemical prospecting information,construct the digital model of prospecting area,further use of "cube model" theory method were quantitative statistical analysis what mineralization favorable factors of exploration area,and then established the prediction model of 3D.On the basis of the exploration area,the favorable target area are delneated in the exploration area,the mineral resources in the exploration area were initially determined and the probability evaluation of forecasting work.Through the establishment three-dimensional geological model and drilling engineering model and ore-body model of Zou-Jiashan uranium exploration area,provide accurate and comprehensive 3D data for later geological work,provides 3D visualization data for mine development and production;at the same time this study realized location,quantity and fixed probability the 3D metallogenic prediction in exploration area,further to the study area of deep mineralization zones were analyzed,for the later further exploration area of deep and periphery prospecting exploration to provide advice.
