日本工业技术院从1981年开始,制定了开采4000～6000米深海底锰结核的大型科研计划。采矿系统中的集矿系统的研究是最复杂的,因为研制集矿机械,必须试验集矿机对深海底堆积层的力学作用,只有了解了堆积层的承载力、沉降特性、集矿机行走时受堆积层粘着阻力的影响等问题,才能研制出 Nippon Institute of Technology began in 1981, developed a large-scale research program mining 4000 ~ 6000 m deep sea manganese nodules. The study of the ore-collecting system in the mining system is the most complicated. Because the development of the ore-collecting machinery, the mechanical action of the ore-concentrator on the deep-sea floor must be tested. Only by knowing the bearing capacity and settlement characteristics of the accumulating layer, By the accumulation of layer adhesion resistance and other issues, in order to develop
