Section 2 reviews mechanical properties fracture mechanism seabed related continental rocks, which contributes to advancement relevant technologies theories. Deep-sea systems developed coastal countries are presented 3. Seabed mineral collection system critically assessed 4. Subsea vehicle is...
Abstract Chip is a visual representation of rock breaking by cutter, and their related parameters are crucial for revealing the mechanism in deep-sea mining. Based on sieving three-dimensional size measurement methods widely used mining engineering, this paper reports dataset chip chisel pick under hydrostatic pressure. Specifically, we first designed an experimental setup that can accurately simulate pressure, conducted experiments carefully collected chips. Subsequently, those chips were...
Double-row hydraulic collectors are extensively utilized for deep-sea polymetallic nodule harvesting. Understanding the movement behavior of particles within flow field is crucial evaluating efficiency collection system and guiding design collectors. This study first investigates settling characteristics in various environments to assess effects high-pressure low-temperature conditions on particle motion. Subsequently, motion force under different double-row jet parameters were measured...
