摘要：边界品位是估计矿产资源量和储量的关键参数，用于区分矿石和岩石。一个符合矿床开发技术经济特征的边界品位，将为采矿项目带来应有的利润。常用的边界品位确定方法有盈亏平衡点法、演进法和蓝氏法。盈亏平衡点法简单易行，体现了成本-价格-利润之间的基本规律，在矿产勘查、矿山项目可行性研究和矿山生产阶段均可使用。演进法和蓝氏法细化了经济技术因素，适合在可行性研究与矿山生产阶段使用。本文在一般介绍各种边界品位估计方法的基础上，重点阐述盈亏平衡点法在矿产勘查中的应用。

Abstract: Cut off grade is a key parameter for estimating mineral resources and reserves, which is used to distinguish ore from rock. A cut off grade in line with the technical and economic characteristics of the deposit will bring due profits to the mining project. At present, the commonly used cut-off grade determination methods include break-even method, heuristic method and Lane’s method. The break-even method is simple and feasible without losing the cost-price-profit law. It can be applied in mineral exploration, mine project feasibility study and mine production. The heuristic method and Lan’s method refine the economic and technical factors, which are suitable for application in the stage of feasibility study and mine production. After the general introduction of various cut-off grade determination methods, this paper focuses on the applications of break-even method in mineral exploration.
