摘　　要：以国外某铜钴矿床为例,应用动态搜索估值方法对其褶皱发育的矿体进行估值,并与定向估值法进行比较。结果显示固定搜索椭球体产状唯一,仅适用于产状单一稳定的矿体估值;对于产状复杂,尤其是褶皱发育及受地层控制的矿体,采用动态搜索估值法得到的品位分布及矿体形态更加符合地质规律。通过预先建立复杂矿体的近似产状面,利用产状面的每个三角面产状属性对椭球体搜索方向进行动态控制,动态搜索估值可达到模拟复杂矿体形态的目的。Taking a foreign copper-cobalt deposit as an example,the dynamic search valuation method is applied to value its fold-developed ore body,and compared with the targeted valuation method.The results show that the fixed searching for ellipsoids has a unique occurrence and is only applicable to the valuation of ore bodies with a single and stable occurrence.For ore bodies with complex occurrence,especially those developed by folds and controlled by strata,the grade distribution and ore body morphology obtained by the dynamic search valuation method are more in line with geological rules,By establishing an approximate occurrence surface of complex ore bodies in advance,and utilizing the occurrence attributes of each triangular plane of the occurrence surface to dynamically control the search direction of ellipsoids,dynamic search valuation can achieve the purpose of simulating the morphology of complex ore bodies.
