摘要
本文提出金属矿产详查决策数学模型。该模型包括确定矿体品位区间的对数正态模型和确定最低工业品位的数学模型。提出了采用不同边界品位值,多方案圈定矿体;根据其期望总利润值确定最优方案的原则。并以个旧和银岩两个锡矿区的矿床为例,具体说明了该模型的应用。最后给出该模型计算机程序框图。
This paper suggests the mathematical model of prospecting decision for metal-lic ore deposits. The authors use the different cut-off grade values and several plans for the delineation of ore body, and suggest the principles for determination of the optimal plan according to the expectation value of total profit of each plan. Taking the two tin deposits-Gejiu and Yinyan as an example, the application of this model has been concretely illustrated. Finally the computer functional-block diagram is given.
