“…In 2013 and 2015, the Korea Advanced Institute of Ocean Science and Technology conducted sea trials for deep-sea mining vehicles and hydraulic lifting systems, respectively. CSU and Cebynetic developed second-generation DSMV [10]. However, no mature development pattern of marine mineral wealth exists globally, nor has commercial exploitation been realized in developed countries.…”

“…The outlet angle of the impeller blade has a great influence on the performance of the pump, and it is advantageous to have a higher impeller outlet angle as it helps minimize both friction loss within the impeller and the overall radial size. The Korea Institute of Geological Marine Resources (KIGAM) established an experimental system to study lifting pumps [10]. In view of the lateral thrust suffered by the lifting pump, although researchers have proposed a large number of theoretical formulas to evaluate the axial thrust of the pump, there is still a discrepancy observed between the computed outcomes and the recorded axial force during practical operational testing [97].…”

“…However, the operating environment inside the deep-sea is extremely harsh and complex, and still, only a few commercial organizations and countries are able to make use of deep-sea minerals. There are many operational problems in the deep-sea environment, such as the interaction of various mining devices [9], soft deep-sea geological environment, low temperature, and high pressure [10].…”

In response to the anticipated scarcity of terrestrial land resources in the coming years, the acquisition of marine mineral resources is imperative. This paper mainly summarizes the development of underwater collection and transportation equipment of polymetallic nodules in deep-sea mining. Firstly, the collection equipment is reviewed. The deep-sea mining vehicle (DSMV), as the key equipment of the collection equipment, mainly includes the collecting device and the walking device. The micro and macro properties of sediments have a great influence on the collection efficiency of mining vehicles. For the collecting device, the optimization of the jet head structure and the solid–liquid two-phase flow transport of the hose are discussed. The structure of the walking device restricts mining efficiency. The optimization of the geometric structure is studied, and the geometric passability and lightweight design of the walking device are discussed. Secondly, the core of transportation equipment is the lifting device composed of a riser and lifting pump. In order to explore the key factors affecting mineral transport, the lifting device is summarized, and the design optimization of the lifting pump and the factors affecting the stability of the riser are discussed. Then, the relationship between each device is discussed, and the overall coupling of the device is summarized. Finally, the existing problems and future research focus are summarized.

“…The deep-sea, typically situated 200 meters below sea level, represents one of the largest and most challenging-to-access biological habitats on Earth. Nonetheless, deep-sea mining has attracted global attention, prompting national mining companies and scientific research institutes to pursue reasoned approaches to deep-sea mining 2,3 . Currently, the predominant mining method for rock-based polymetallic sulfides (PMS) is the Pipe-Lift Mining System, which involves mining vehicle, pipe, and sea support vessel 4 .…”

Chip is a visual representation of rock breaking by cutter, and their related parameters are crucial for revealing the rock breaking mechanism in deep-sea mining. Based on sieving and three-dimensional size measurement methods widely used in mining engineering, this paper reports a dataset of chip parameters for rock breaking by chisel pick under deep-sea hydrostatic pressure. Specifically, we first designed an experimental setup that can accurately simulate deep-sea hydrostatic pressure, conducted rock breaking experiments and carefully collected chips. Subsequently, those chips were sieved, high-resolution images were collected, and the coarseness index (CI), chip size uniformity (n), absolute chip size (de), and fractal dimension (D) were measured. Finally, three-dimensional size (long, intermediate and short) was measured for 3064 chips with particle sizes greater than 4.75 mm. This dataset will be used by researchers to validate numerical simulations or optimize equipment structures related to deep-sea mining, including deep-sea rock mechanics, mining cutter and conveyor pipes.

The aim of this paper is to propose a novel method for identifying the hydrodynamic parameters of a deep‐sea mining vehicle during deployment and retrieval. The proposed approach combines numerical simulation with a nonlinear filter. Initially, a dedicated hydrodynamic model for the deployment and retrieval of the mining vehicle is constructed. The identification process commences with simulations based on computational fluid dynamics (CFD). This approach utilizes CFD to simulate the motion of the deep‐sea mining vehicle during deployment and retrieval, employing an implicit solution approach to analyze its motion in Heave and Yaw degrees of freedom under periodic external forces. Consequently, this provides hydrodynamic performance data. Subsequently, the unscented Kalman filter (UKF) estimator is applied to optimally solve an augmented matrix that incorporates both motion data and hydrodynamic parameters, yielding numerical values for the hydrodynamic parameters. Simulation results demonstrate that, in comparison to motion performance obtained by the CFD method, the hydrodynamic model derived from UKF enables an effective prediction of the motion of the deep‐sea mining vehicle, with prediction errors consistently below 6%.
