Figures 1 to 3 As shown, the new green mining system for deep-sea sulfide resources includes: a sea surface support subsystem 10, a pipeline transportation subsystem 20, an integrated maintenance and environment perception subsystem 30 and a seabed mining subsystem 40.

[0021] The sea surface support subsystem 10 is used to be set on the sea surface, the seabed mining subsystem 40 is used to be set on the seabed, and closed mining is carried out on the seabed. The pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40, and the pipeline transportation subsystem 20 is used to transport the minerals mined by the seabed mining subsystem 40 to the sea surface support subsystem 10. The comprehensive maintenance and environmental perception subsystem 30 is set near the pipeline transportation subsystem 20, the seabed mining subsystem 40 and the sponge support subsystem to monitor various data during the mining process; wherein, the sea surface support subsystem 10 is a semi-submersible platform.

[0022] The sea surface support subsystem 10 is arranged on the sea surface, the seabed mining subsystem 40 is arranged on the seabed, and vertical closed green mining is carried out on the seabed. The pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40, and the pipeline transportation subsystem 20 is used to transmit the minerals mined by the seabed mining subsystem 40 to the sea surface support subsystem 10. The comprehensive maintenance and environmental perception subsystem 30 is respectively arranged on the sea surface support platform 11 and in the seawater, and the comprehensive maintenance and environmental perception subsystem is used to perform hardware maintenance, environmental monitoring, integrated control, etc. on the mining system; wherein, the sea surface support platform 11 is a semi-submersible platform.

[0023] It should be noted that the sea surface support subsystem 10 includes a sea surface support platform 11 .

[0024] In the embodiment of the present application, since the pipeline transportation subsystem 20 is connected to the seabed mining subsystem 40 and the sea surface support subsystem 10 is arranged on the sea surface, when it is necessary to mine the seabed, the seabed mining subsystem 40 is deployed on the seabed, and the seabed mining subsystem 40 performs vertical closed mining. The minerals mined by the seabed mining subsystem 40 can be transmitted to the sea surface support subsystem 10 through the pipeline transportation subsystem 20, and the sea surface support platform 11 is a semi-submersible platform, which can avoid the pipeline transportation subsystem 20 from transmitting the minerals mined by the seabed mining subsystem 40 to the ship, resulting in limited continuity and stability of the mining system. That is, in the embodiment of the present application, by setting the sea surface support platform 11 as a semi-submersible platform, and the seabed mining subsystem 40 performs vertical closed mining on the seabed, the seabed mining subsystem 40 can cause less pollution to the seabed environment during the process of mining minerals, and after the minerals mined by the seabed mining subsystem are transmitted to the sea surface support subsystem 10 via the pipeline transportation subsystem 20, the minerals are stored on the sea surface support platform 11, which can effectively avoid the problem of small amount of mineral storage on the ship and limited continuity of mining operations. That is, in the embodiment of the present application, when mining on the seabed, not only is the pollution to the seabed environment less, but the continuity and stability of seabed mining can also be achieved.

[0025] In the related art, when mining the seabed, the ship is usually floated on the sea surface, and the mining machine is placed on the seabed. The mining machine mines on the seabed, and the mining machine is connected to the pipeline transportation subsystem 20, and the pipeline transportation subsystem 20 transmits the minerals mined by the mining machine to the ship. In this way, the mining machine will generate a lot of dust on the bottom of the seabed during the process of mining minerals, causing serious turbidity of the seawater on the seabed, affecting the environment of the seabed. The ship is occupied by the mined minerals, resulting in the ship being able to dock only at the corresponding sea surface, and the ship cannot perform other tasks, resulting in a significant reduction in the utilization rate of the ship, and the ship is greatly affected by the weather at sea, which makes it extremely difficult to achieve stability and continuity of seabed mining. In the embodiment of the present application, the sea surface support platform 11 is set as a semi-submersible platform, and the pipeline transportation subsystem 20 transmits the mined minerals to the semi-submersible platform, thereby freeing the ship so that the ship can move freely and perform other tasks, thereby improving the utilization rate of the ship. In addition, the semi-submersible platform is relatively stable and not easily affected by waves or sea breezes, so that the minerals placed on the semi-submersible platform are relatively stable. In addition, the seabed mining subsystem 40 performs closed mining, so that when the seabed mining subsystem 40 mines minerals on the seabed, the dust generated during the mining process is less transmitted to the seabed, and is only in the mine pit 001 mined by the seabed mining subsystem 40, thereby avoiding pollution of the seabed environment and effectively protecting the seabed environment.

[0026] It should be noted that in the embodiment of the present application, once the pipeline transportation subsystem 20 transfers the mined minerals to the sea surface support platform 11, when the minerals need to be transported, the minerals on the sea surface support platform 11 can be transported by the sea surface transfer ship 16, that is, the sea surface transfer ship 16 is moved around the sea surface support platform 11, and the minerals on the sea surface support platform 11 are transported to the sea surface transfer ship 16, and the sea surface transfer ship 16 transports the minerals to the destination.

[0027] In addition, in some embodiments, the seabed mining subsystem 40 includes a support module 41, an isolation cover 42, a mining module 43 and a temporary silo 44, the isolation cover 42 is connected to the support module 41, and the temporary silo 44 is connected to the pipeline transportation subsystem 20; the mining module 43 is used to excavate a mine 001 on the seabed and mine ore in the mine 001, the isolation cover 42 is used to seal the overflow of turbid water generated during the mining process, so that the seabed mining subsystem 40 can perform vertical closed green mining, and the temporary silo 44 is used to temporarily store the ore mined by the mining module 43 and perform preliminary filtration, and then transport it to the sea surface support subsystem through the pipeline transportation subsystem 20.

[0028] Due to the isolation cover 42 and the mining module 43, when the mining module 43 excavates the mine 001 on the seabed, the isolation cover 42 can cover the mine 001, so that the dust generated by the mining module 43 during the excavation process is blocked by the isolation cover 42, so that more suspended matter is concentrated in the mine 001, less suspended matter leaks to the seabed, and even all suspended matter is concentrated in the mine 001, thereby realizing closed mining. That is, by setting the isolation cover 42 and the mining module 43, the seabed environment can be effectively protected during the mining process on the seabed.

[0029] It should be noted that in the embodiment of the present application, the mining module 43 can excavate the mine 001 in a direction perpendicular to the seabed, which is equivalent to the extension direction of the excavated mine 001 being perpendicular to the seabed, that is, the extension direction of the mine 001 is vertical, and the mining module 43 can be extended and retracted in the horizontal direction to expand the size of the mine 001. During the excavation of the mine 001, the isolation cover 42 will cover the opening of the mine 001, so that the dust generated by the mining module 43 during the mining process is only concentrated in the mine 001, thereby preventing dust from leaking to the seabed.

[0030] In addition, in the embodiment of the present application, an opening can be set on the isolation cover 42, and the mining module 43 passes through the opening, and the mining module 43 can move relative to the isolation cover 42, so that in the process of mining minerals by the mining module 43, the mining module 43 moves relative to the isolation cover 42, and the isolation cover 42 always covers the opening of the mine 001 excavated by the mining module 43 to prevent dust from leaking to the seabed.

[0031] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources for mineral mining may also include an energy supply module 12, which is arranged on the sea surface support platform 11, or the energy supply module is arranged on the sea surface around the sea surface support subsystem 10; wherein the energy supply module 12 is electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, respectively, for providing electrical energy to the seabed mining subsystem 40 and the pipeline transportation subsystem 20.

[0032] Since the energy supply module 12 is electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, respectively, the electric energy generated by the energy supply module 12 can be transmitted to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, so that the seabed mining subsystem 40 and the pipeline transportation subsystem 20 can operate normally. In addition, the energy supply module 12 can be arranged on the sea surface support platform 11 or the sea surface around the sea surface support subsystem 10, so that the distance between the energy supply module 12 and the pipeline transportation subsystem 20 and the distance between the seabed mining subsystem 40 can be relatively close, which can save the length of the cable that needs to electrically connect the energy supply module 12 and the pipeline transportation subsystem 20, and can also save the length of the cable that needs to electrically connect the energy supply module 12 and the seabed mining subsystem 40.

[0033] In addition, in some embodiments, the energy supply module 12 may include a plurality of photovoltaic components and a bracket, the bracket is arranged on the sea surface support platform 11, and a plurality of photovoltaic components are arranged on the bracket, and the photovoltaic components are respectively electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, so as to provide electric energy for the seabed mining subsystem 40 and the pipeline transportation subsystem 20; or, the energy supply module 12 includes a wind power generation device and a power generation support frame, the power generation support frame is arranged on the sea surface support platform 11, and the wind power generation device is arranged on the power generation support frame, and the wind power generation device is respectively electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, so as to provide electric energy for the seabed mining subsystem 40 and the pipeline transportation subsystem 20. The subsystem 20 provides electrical energy; or, the energy supply module 12 includes a plurality of wave energy power generation components, which are arranged on the sea surface around the sea surface support subsystem 10, and the wave energy power generation components are electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, respectively, to provide electrical energy for the seabed mining subsystem 40 and the pipeline transportation subsystem 20; or, the energy supply module 12 includes a plurality of tidal energy power generation components, which are arranged on the sea surface around the sea surface support subsystem 10, and the tidal energy power generation components are electrically connected to the seabed mining subsystem 40 and the pipeline transportation subsystem 20, respectively, to provide electrical energy for the seabed mining subsystem 40 and the pipeline transportation subsystem 20.

[0034] When the energy supply module 12 includes a plurality of photovoltaic modules and brackets, the brackets can be set on the sea surface support platform 11, and the plurality of photovoltaic modules can be set on the brackets, so that the photovoltaic modules can convert the sunlight irradiated on the sea surface, that is, convert solar energy into electrical energy, and then transmit the electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, so that the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can operate normally. That is, by setting up a plurality of photovoltaic modules, solar energy can be effectively utilized, so that clean energy can be maximized, and the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can be ensured, avoiding the use of thermal power generation in the related technology to power the pipeline transportation subsystem 20 and the seabed mining subsystem 40, thereby improving the protection of the environment. Among them, the bracket can also be set on the sea surface around the sea surface support subsystem 10.

[0035] When the energy supply module 12 includes a wind power generation device and a power generation support frame, the power generation support frame can be set on the sea surface support platform 11, and the wind power generation device can be set on the power generation support frame, so that the wind power generation device can convert the wind energy on the sea surface into electrical energy, and then transmit the electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, so that the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can operate normally. That is, by setting up the wind power generation device, the wind energy on the sea surface can be effectively utilized, so that the clean energy can be maximized, the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can be ensured, and the use of thermal power generation in the relevant technology to power the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can be avoided, thereby improving the protection of the environment. Among them, the power generation support frame can also be set on the sea surface around the sea surface support subsystem 10.

[0036] When the energy supply module 12 includes multiple groups of wave energy power generation components, the multiple groups of wave energy power generation components can be set on the sea surface around the sea surface support subsystem 10, so that the wave energy power generation components can convert the wave energy irradiated on the sea surface, that is, convert the wave energy into electrical energy, and then transmit the electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, so that the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can operate normally. That is, by setting up multiple groups of wave energy power generation components, wave energy can be effectively utilized, so that clean energy can be maximized, and the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can be ensured, and the use of thermal power generation to power the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in the related technology can be avoided, thereby improving the protection of the environment.

[0037] When the energy supply system 40 includes multiple sets of tidal power generation components, the multiple sets of tidal power generation components can be set on the sea surface around the sea surface support subsystem 10, so that the tidal power generation components can convert the tidal energy irradiated on the sea surface, that is, convert the tidal energy into electrical energy, and then transmit the electrical energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, so that the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can operate normally. That is, by setting up multiple sets of tidal power generation components, tidal energy can be effectively utilized, so that clean energy can be maximized, and the normal operation of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can be ensured, and the use of thermal power generation to power the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in the related technology can be avoided, thereby improving the protection of the environment.

[0038] In addition, in the embodiment of the present application, the new green mining system for deep-sea sulfide resources may further include an energy storage module, which is arranged in the sea surface support subsystem 10, and the energy storage module is electrically connected to the energy supply module 12, and the energy storage module is used to store the electric energy generated by the energy supply module 12. Among them, by setting the energy storage module, the energy storage module can store the excess electric energy generated by the energy supply module 12, and the energy storage module can be electrically connected to the pipeline transportation subsystem 20 and the seabed mining subsystem 40 through the switch assembly, so that when the energy supply module 12 fails, the switch assembly can be in a closed state, and the energy storage module can transfer the stored electric energy to the pipeline transportation subsystem 20 and the seabed mining subsystem 40, so that the pipeline transportation subsystem 20 and the seabed mining subsystem 40 can operate normally. After the energy supply module 12 is repaired, the switch assembly is in an open state, so that the energy supply module 12 provides electric energy for the pipeline transportation subsystem 20 and the seabed mining subsystem 40.

[0039] It should be noted that the energy storage module may be an energy storage battery pack.

[0040] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources may also include an ore silo 14, which is arranged on the sea surface support platform 11, and the ore silo 14 is connected to the ore primary selection module 13, and the pipeline transportation subsystem 20 is used to transport the minerals mined by the seabed mining subsystem 40 to the ore silo 14.

[0041] Since the ore silo 14 is connected to the pipeline transportation subsystem 20, once the seabed mining subsystem 40 mines the minerals and the minerals are moved to the pipeline transportation subsystem 20, the pipeline transportation subsystem 20 can transfer the minerals to the ore primary selection module 13. The ore primary selection module 13 performs primary selection of the ore and then transports the ore to the ore silo 14, so that the ore silo 14 can store the minerals, which is convenient for the subsequent transfer of the minerals by ship, and avoids the problem of the minerals being scattered on the sea surface support platform 11 and difficult to transfer.

[0042] It should be noted that, in the embodiment of the present application, the pipeline transportation subsystem 20 may include a lifting pump 21, a relay station 22, a rigid pipe 23 and a flexible pipe 24. The lifting pump 21 is connected to the riser 23, the relay station 22 is connected to the lifting pump 21 through the riser 23, and the flexible pipe 24 is connected to the relay station 22. In practical applications, the flexible pipe 24 can be connected to the seabed mining subsystem 40, and the other end can be connected to the relay station 22, and a multi-stage lifting pump 21 is set. After the lifting of the multi-stage lifting pump 21, the minerals mined by the seabed mining subsystem 40 are transferred to the flexible pipe, and then transferred and stored through the relay station 22. Once the minerals enter the rigid pipe 23, the rigid pipe 23 can lift the minerals to the sea surface support platform 11. Among them, the number of rigid pipes 23 can be multiple, and multiple rigid pipes 23 are connected. The energy supply system 40 is electrically connected to the lifting pump 21 to provide electrical energy to the lifting pump 21.

[0043] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources may further include an ore preliminary selection module 13, which is arranged in the sea surface support subsystem 10, and is connected to the ore silo 14, and is used to perform preliminary selection and transport the sulfide ore transported by the pipeline transportation subsystem 20 to the ore silo 14. By setting the ore preliminary selection module 13, the pipeline transportation subsystem 20 transmits the minerals mined by the seabed mining subsystem 40 to the ore preliminary selection module 13, and the ore preliminary selection module 13 can perform preliminary screening on the ore, remove impurities in the ore, and make the ore impurities stored in the subsequent ore silo 14 less.

[0044] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources may also include an anti-oxidation module 15; the anti-oxidation module 15 is connected to the ore bin 14, and the anti-oxidation module 15 stores a protective gas. The anti-oxidation module 15 is used to inject the protective gas into the ore bin 14 so that the minerals in the ore bin 14 are in contact with the protective gas, and the protective gas is used to prevent the minerals from being oxidized.

[0045] Since the anti-oxidation module 15 is connected to the ore bin 14 and the anti-oxidation module 15 stores protective gas, the protective gas can be injected into the ore bin 14 through the anti-oxidation module 15, so that once the mineral is transferred to the ore bin 14 by the ore primary selection module 13, the mineral contacts the protective gas, thereby preventing the mineral from being oxidized by oxygen in the air in the ore bin 14, which affects the subsequent utilization of the mineral. That is, by setting the anti-oxidation module 15, the anti-oxidation module 15 can inject protective gas into the ore bin 14, so that the mineral in the ore bin 14 is less oxidized, avoiding the oxidation of the mineral and causing the subsequent utilization rate of the mineral to be reduced, which is equivalent to setting the anti-oxidation module 15, which can effectively improve the utilization rate of the mineral.

[0046] It should be noted that the protective gas may be nitrogen, and of course, the protective gas may also be other types of gases, for example, the protective gas is argon. The specific type of the protective gas is not limited in the embodiments of the present application.

[0047] In addition, in an embodiment of the present application, the anti-oxidation module 15 may include a transmission pipe and a gas storage component, the gas storage component is connected to the transmission pipe, and the transmission pipe is connected to the ore bin 14.

[0048] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources for mineral mining may also include an integrated maintenance and environmental sensing subsystem 30. The integrated maintenance and environmental sensing subsystem 30 is used to move on the seabed along the extension direction of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to perform hardware maintenance on the pipeline transportation subsystem 20 and the seabed mining subsystem 40 and monitor the hardware and environment during the mining process. Through such a setting, during the mining process of the seabed mining subsystem 40, the comprehensive maintenance and environmental perception subsystem 30 can monitor the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in real time, monitor whether the pipeline transportation subsystem 20 is leaking, leaking minerals into the sea, causing seawater pollution, and the comprehensive maintenance and environmental perception subsystem 30 can also monitor whether the pipeline transportation subsystem 20 is damaged, ensuring that the pipeline transportation subsystem 20 can transport minerals more safely, and the comprehensive maintenance and environmental perception subsystem 30 can monitor the impact of the seabed mining subsystem 40 on the surrounding environment during the mining process to avoid damage to the environment. At the same time, the comprehensive maintenance and environmental perception subsystem 30 can perform real-time maintenance on the hardware of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to ensure the continuity and stability of the mining process.

[0049] In addition, in some embodiments, the comprehensive maintenance and environmental perception subsystem 30 may include hardware maintenance equipment 31, hardware and environmental monitoring equipment 32, platform monitoring equipment 33 and monitoring sensors; the monitoring sensors are arranged on the hardware maintenance equipment 31 and the hardware and environmental monitoring equipment 32, the hardware maintenance equipment is movable along the extension direction of the pipeline transportation subsystem 20 and the seabed mining subsystem 40, and performs hardware maintenance on the pipeline transportation subsystem 20 and the seabed mining subsystem 40, the hardware and environmental detection equipment 32 is arranged on the pipeline transportation subsystem 20 and the seabed mining subsystem 40, and performs hardware-side detection and mining environment monitoring, the monitoring sensors are arranged on the pipeline transportation subsystem 20 and the seabed mining subsystem 40, and monitor the working status and parameters of various equipment in real time, and the platform monitoring equipment 33 is arranged on the sea surface support subsystem 10, and is used to perform comprehensive monitoring of the working conditions and environmental data of various equipment.

[0050] Since the monitoring sensors are arranged on the hardware maintenance equipment 31 and the hardware and environment monitoring equipment 32, the hardware maintenance equipment 31 and the hardware and environment monitoring equipment 32 can be placed in the sea, so that the hardware maintenance equipment 31 and the hardware and environment monitoring equipment 32 move in the water along the extension direction of the pipeline transportation subsystem 20, so that the monitoring sensors can detect the pipeline transportation subsystem 20 and the seabed mining subsystem 40, and in the process of equipment movement, the monitoring sensors monitor the pipeline transportation subsystem 20 and the seabed mining subsystem 40 in real time, and can comprehensively monitor the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to ensure the safety of the pipeline transportation subsystem 20 in transmitting minerals and the seabed mining subsystem 40 in mining minerals. At the same time, the hardware maintenance equipment 31 performs real-time maintenance on the hardware of the pipeline transportation subsystem 20 and the seabed mining subsystem 40 to ensure the continuity and stability of the mining process. In addition, the platform monitoring equipment 33 is arranged on the sea surface support subsystem 10, so that the platform monitoring equipment 33 can summarize the working conditions and environmental data of various equipment, conduct comprehensive monitoring, and ensure the safety and stability of the mining process.

[0051] It should be noted that the hardware maintenance device 31 and the hardware and environment monitoring device 32 may be cruise robots. In addition, the monitoring sensor may include but is not limited to an infrared sensor, a camera, a turbidity sensor, an environment detector, and the like.

[0052] In addition, in some embodiments, the new green mining system for deep-sea sulfide resources may also include a platform monitoring device 33, which is arranged on the sea surface support platform 11, and is connected to the hardware maintenance device 31 and the hardware and environment monitoring device 32. The platform monitoring device 33 is used to receive detection information sent by the hardware maintenance device 31 and the hardware and environment monitoring device 32, and to issue prompt information.

[0053] Since the platform monitoring device 33 is electrically connected to the hardware maintenance device 31 and the hardware and environment monitoring device 32, the hardware maintenance device 31 and the hardware and environment monitoring device 32 can send the detected detection information to the platform monitoring device 33 in real time. The platform monitoring device 33 can issue prompt information based on the detection information, thereby prompting the operator, so that the operator can know the status of the seabed environment and protect the seabed environment.

[0054] Among them, after receiving the detection information, the platform monitoring device 33 can judge the detection information. If the value representing the seabed environment in the detection information is greater than the preset threshold, the platform monitoring device 33 issues a prompt message. Specifically, the hardware maintenance device 31 and the hardware and environment monitoring device 32 can detect the detection value of the seabed environment and send the detection value to the platform monitoring device 33. When the platform monitoring device 33 determines that the detection value is greater than the preset threshold, it indicates that the seabed environment is polluted, and the platform monitoring device 33 issues a prompt message. It should be noted that the detection value includes but is not limited to turbidity value, sulfide value, etc.

[0055] In addition, the prompt information can be a prompt sound, in which case the platform monitoring device 33 includes a voice module; of course, the prompt information can also be an alarm light, in which case the platform monitoring device 33 includes an alarm light. Of course, the platform monitoring device 33 can include both a voice module and an alarm light, so that the platform monitoring device 33 can emit both a prompt sound and an alarm light.

That is, in the embodiment of the present application, by setting the sea surface support subsystem as a semi-submersible platform and the seabed mining subsystem performs closed mining on the seabed, the seabed mining subsystem can cause less pollution to the seabed environment during the process of mining minerals, and after the minerals mined by the mining module are transmitted to the sea surface support subsystem through the pipeline transportation subsystem, the minerals are stored on the semi-submersible platform, which can effectively avoid the problem of small amount of mineral storage in the ship and limited continuity of mining operations. At the same time, the integrated maintenance and environmental perception subsystem can be used to monitor the equipment and mining environment in real time during mining operations, and can perform real-time maintenance on the equipment. That is, in the embodiment of the present application, when mining on the seabed, not only is the pollution to the seabed environment less, but the continuity and stability of seabed mining can also be achieved.
