In order to solve the problem of low reliability of research results caused by the lack of
simulated materials for seafloor massive sulfide (SMS) in laboratory breaking research, this …

The research of seafloor massive sulfide cutting characteristics is in the initial stage, and
experimental methods are rarely used to conduct research. In addition, the mechanism of …

Drilling into deep formation characterized by high formation and hydrostatic pressures often
brings great challenges to oil and gas industry and the phenomena, such as bit slip, balling …

The design and selection of tools for mechanized excavations is a crucial topic in the field of
tunneling. Chisel bits are commonly used tools for soft ground, with the required cutting force …

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 …

Research on cutting seafloor massive sulfide is in its initial stages; however, the breaking
characteristics are unclear. In addition, the influence of water was not considered in the …

The existing experimental and numerical simulations on the rock-cutting by PDC cutter have
focused primarily on dry rocks (DR), with limited research on the cutting of saturated rocks …

Recognising the advantages of the cavitation jet, we propose the utilisation of a rotating self-
propelled cavitation jet for tube cleaning. In this study, we conducted a performance …
