Fundamental geotechnical considerations for design of deep-sea mining systems

Abstract

The importance of manganese nodules, seafloor massive sulfides, and cobalt-rich manganese crusts as future metal sources has been well recognized. However, less geotechnical information of the resources is available to aid the design of mining system. The results of fundamental studies for geotechnical characteristics of the resources and sediments associated with the resources are presented in this chapter. Effects of the characteristics on the design of mining system are examined. Some additional engineering and economic considerations for the design are also discussed.
