矿块大小论证及估值参数优化研究
|
摘要
选择合适的矿块尺寸和估值参数对于准确的资源量估算和减少错误的矿岩分类(损失率和贫化率)非常重要。但是目前,国内对于该方面的研究内容相对较少,相关参数的选取也比较随意,直接影响了估值结果。本文通过定性评价和定量分析(KNA)方法,论述如何选择最优的资源模型矿块尺寸和估值参数,以期取得最优的估值结果。
Selecting the appropriate block size and resource estimation parameters are extremely important for achieving accurate estimation and minimizing misclassification(loss and dilution).However,at present,the research on this aspect is relatively few in China,and the selection of relevant parameters is relatively random,which directly affects the estimation results.Through qualitative evaluation and quantitative analysis(KNA),it discusses how to select the optimal block size and resource estimation parameters in order to get the optimal estimation results.
