【摘要】 本文以河南南泥湖-三道庄地区钼矿为例,借助国际主流矿业软件Micromine,应用钻孔数据库,建立该地区钼矿的三维可视化矿体模型,充分反映了钼矿的实际形态。本文分别采用普通克里格法,指示克里格法对己建立的钼矿品位模型进行估值,并用距离反比加权法进行结果验证,结果表明预测储量在误差允许的范围内,预测结果较为理想。更多还原

【Abstract】 This paper takes Nannihu-Sandaozhuang molybdenum in Henan as an example,with the help of the mainstream international mining software Micromine,application of borehole database,visualization of3 D orebody model established in the area of molybdenum ore,fully reflect the actual form of molybdenum.Ordinary kriging and indicator kriging valuated for molybdenum ore grade established models,the result of inverse distance weighting method to verify shows that the prediction error of reserves within the allowable range,forecast result is sucessful.更多还原
