传统的海底采矿系统使用重型海底履带，其具有大钻头并且水平地刮擦矿物存款，并且具有海底倾斜度、粗糙度和柔软度的限制。这些传统的系统也存在操作和经济方面的问题。此外，传统的船载钻机和海底钻机用于钻探取样，以分析海底矿床的矿物含量在矿产资源评估阶段的生产之前，但操作和经济效率的要求，以及这些传统的系统，本研究的目的是开发一种创新的自行走垂直采矿系统（SW-VMS），克服这些问题。该系统是一个完全浸没的八腿自升式平台，能够在粗糙，柔软和倾斜的海底自主行走。SW-VMS既可作为海底采矿系统，又可在潜孔钻机采矿前作为取样钻探系统，有效地进行现场和陆上矿物含量分析。本文首先介绍了SW-VMS作为采矿系统的详细情况，然后介绍了SW-VMS作为取样钻探系统的概念，最后介绍了SW-VMS的缩尺模型试验结果。VMS陆地显示。进行了缩尺模型试验，从结构和自主控制的角度确认了SW-VMS的行走能力。试验模型的规模约为已经完成的SW-VMS初步设计的1/40。该测试包括在平坦基础上行走的测试用例，包括部分软基础的平坦基础和高达45度的倾斜基础。
Traditional subsea mining systems use a heavy subsea crawler, which has a big drill and scrapes the mineral deposit horizontally and have limitations of seafloor inclination, roughness and softness. Those traditional systems also have issues from operational and economical points of view. Furthermore, traditional on-board drilling machines and seabed drilling machines are used for core sampling by drilling to analyze mineral contents of seafloor deposits at the stage of mineral resource estimation before the production but operational and economical efficiencies are required to those traditional systems as well.The objective of this research is to develop an innovative Self-Walking Vertical Mining System (SW-VMS) that overcomes these issues. The system is a fully submerged eight-legged jack up platform and is able to walk autonomously on a rough, soft and inclined seafloor. The SW-VMS can be used both as the mining system to mine seafloor deposits and as the sample drilling system to analyze mineral contents in-situ and on-land efficiently before the mining with a DTH drilling unit.This paper introduces the detail of the SW-VMS as the mining system at first and then introduces the concept of the SW-VMS as the sample drilling system and finally the results of the scale model test of the SW-VMS on-land are shown. The scale model test has been carried out to confirm the walking ability of the SW-VMS from the structural and autonomous control points of view. The scale of the test model is approximately 1/40 of the preliminary design of the SW-VMS which has been already completed. The test consists of test cases of walking on a flat foundation, on a flat foundation including partially soft foundations and on inclined foundations of up to 45 degrees.
