Buffer system for mining deep seafloor mineral resource

A buffer system for mining a deep seafloor mineral resource, the buffer system comprising:

• a hopper part that introduces and stores a crushed mineral resource to discharge the crushed mineral resource upward;
• a first pipe that communicates with an upper portion of the hopper part to introduce the mineral resource;
• a feeder part provided under the hopper part to discharge the mineral resources upward;
• a second pipe that communicates with the feeder part and lifts the mineral resource;
• a hydraulic part provided under the hopper part to convert power received from a surface boat into hydraulic power to operate at least one actuator and a driving motor to introduce the mineral resource into the first pipe;
• a structure frame coupled to a lifting pipe to transmit an external load applied to the buffer system, and constituting an external frame of the buffer system to protect internal units;
• and
• a measurement control unit to remotely control the feeder part and the hydraulic part,
• wherein the measurement control unit is provided in at least one pressure-resistant container to endure pressure under deep sea.
