摘　　要：文章阐述了NSR的基本概念,并通过在加拿大BC省J多金属矿床中的应用实例,介绍了NSR的计算过程,及其在确定多金属矿石边界、不同见矿工程对比、圈定有望勘查靶区中的运用。同时介绍了NSR在经济评价及矿权转让中的作用。The conception of NSR was introduced with using the J polymetallic deposit of BC province as an example. In this paper, authors described the NSR calculation procedure, the application of NSR in selecting cut - off for ore, comparing between different intercepts, defining the potential exploration targets etc. and the NSR application in economic evaluation and in mineral property dealing.
