通过对塔里木盆地北缘铀矿成矿规律的研究,利用找矿分析成果和多元找矿信息,运用层次分析法对研究目标相关地学因素的隶属关系进行了划分,并综合专家的意见,对地学模型进行了层次分析,综合分析的步骤包括:确定研究对象及目标,确定分析所需要的数据;对数据进行分析整理,建立地学数据库;总结研究对象构成目标的相关特征,建立层次指标模型,并运用空间分析提取分析因子;由专家对因子进行综合评分,再运用GIS技术和数学方法进行综合分析,确定模型参数,建立矿床定位预测模型,并对预测单元进行成矿有利度的计算和评价。已知矿体和工程验证结果表明,该方法可较好地用于预测分析和成矿预测单元的分级评价。
Based on the research on the metallogenic regularity of uranium deposits in the northern margin of Tarim Basin, using the results of prospecting and multi-ore prospecting, the subordination relations of geo-related factors of research objectives are analyzed by using the analytic hierarchy process. According to the opinions of experts, The model includes the following steps: determining the research object and target, determining the data needed for the analysis; analyzing and arranging the data to establish the geo-database; summarizing the relevant characteristics of the research object to form the target and establishing the hierarchical index model; The factors are extracted by spatial analysis. The experts score the factors synthetically, and then use GIS technology and mathematical methods to make a comprehensive analysis, determine the model parameters, establish the prediction model of deposit location, and calculate and evaluate the benefit degree of the prediction unit. Known ore bodies and engineering verification results show that this method can be used well in predictive analysis and grading evaluation of ore-forming prediction units.
