摘　　要：大洋富钴结壳是国际海底极为重要的矿产资源，它广泛地分布于水深５００～３０００ｍ的海底山坡上，覆盖率可达７０％～１００％，丰度达３０～７０ｋｇ／ｍ２，富含钴、镍、铜、铂、金、锰等多金属元素。从８０年代起，许多发达国家就开展了广泛的研究。本文从采矿工程角度对我国中太平洋富钴结壳初期调查所取得的资料进行分析研究，这对我国大洋富钴结壳的开发利用有着重要的实用价值和指导意义。Oceanic Coblat enriching crust is greatly important mineral resource on the international sea bottom, which widely distributes over seamount slopes in the water depth of 500～3000m, with cover degree up to 70%～100% and abundance up to 30～70kg/m 2. The crust is rich in many metal elements including coblat, nickel, copper, platinum, gold and manganese. Ever since the 1980′s, Some developed countries have been conducting wide investigation on the crust. From the viewpoint of mining engineering, this paper discusses the information and data obtained by Chinese experts during the preliminary investigation on the coblat enriching crust in the Central Pacific Ocean. The materials and results of their analytical investigation will have a important practial value and directive significance for the exploitation of the Oceanic cobalt enriching crust in China.
