层次分析法在矿床大比例尺定位预测中的应用——以铜陵凤凰山铜矿为例

APPLICATION OF AHP IN PREDICTION OF HIDDEN ORE DEPOSITS IN LARGE-SCALE LOCATION──AN EXAMPLE AT THE FENGHUANGSHAN COPPER DEPOSIT, TONGLING DISTRICT, CHINA

通过铜陵凤凰山铜矿成矿规律研究,利用找矿分析成果和多元找矿信息,运用层次分析法,开展隐伏矿床大比例尺定位预测研究,建立了矿床定位预测模型,并对预测单元进行了成矿有利度计算和评价。已知矿体和工程验证结果表明,该方法可较好地用于大比例尺定位预测分析和成矿预测单元的分级评价。

By applying the AHP(analytic hierarchy process) to prediction of hidden ore deposits in large-scale location based on the results of metallogenetic analysis and mine realization information, a digital model for location prediction of ore deposits was established and the mineralization favorable degrees were computed, in addition to the fact that 8 prospecting prediction cells were evaluated in this paper. The known ore bodies and engineering testing and verification results indicate that the AHP can be well applied to grading and evaluating metallogenetic prediction cells in location prediction of hidden ore deposits.
