The method comprises the following specific steps:
initial state: after the mother ship on the water surface 1 reaches an operation point of an offshore mining area, the mother ship is approximately stopped on the water surface through anchoring and dynamic positioning, a mooring rope 2 with proper length is selected, two ends of the mooring rope 2 are respectively hung with a transfer box, the two transfer boxes are put into the water, and the mooring rope 2 is hung on two guide pulleys 8 arranged at the bow and the stern.
Sinking for the first time: the inner tank 5 in the cabin is lifted out by the boom 7 and loaded into the outer tank 9 in the transfer tank 31 on the bow side of the surface mother ship 1, and the transfer tank 31 is freely sunk with the inner tank 5 therein.
Seabed replacement: when the transfer box 31 on the bow side of the surface mother ship 1 is lowered to the seabed, minerals are loaded into the inner box 5 in the transfer box 31 after the operations of a mining vehicle and a dump truck located on the seabed are completed.

In the sinking process of the operation box 32 at the stern side, the position and orientation information of the outer box body 9 is automatically acquired by the position and orientation sensor 11 arranged on the outer box body 9 of the operation box 32 and transmitted to the information processor 10, and after calculation, the information processor 10 transmits an instruction to the stable-posture propeller to control the driving force and the rotating speed of the four underwater propellers 12, so that the sinking stability of the operation box 32 is ensured.
Seabed replacement: since the length of the wire rope 2 is constant, the operation box 31 on the bow side of the inner box 5 containing the minerals is raised, and the transfer box 31 on the bow side is floated up to the vicinity of the water surface, that is, when the transfer box 32 on the stern side is lowered to the seabed at the same time, the displaced matter 4 in the transfer box 32 is taken out after the completion of the operation of the mining vehicle and the mining vehicle located on the seabed, and the minerals are loaded into the inner box 5 of the transfer box 32.
Water surface replacement: after the completion of the seabed replacement, the inner tank 5 of the bow-side transport tank 31 containing minerals is lifted out by the boom 7 near the bow of the surface mother ship 1 and lifted into the cabin of the surface mother ship 1, and then the replacement 4 is lifted out again from the cabin and placed in the bow-side transfer tank 31 to be allowed to freely sink.
And repeating the steps of seabed replacement and water surface replacement to form a closed loop for mineral lifting, and recovering the operation box to the water surface mother ship 1 after the mineral lifting is finished.
The process of operation case recovery is: assuming that the final state is that the operation box 31 on the bow side of the surface mother ship 1 is near the water surface and the operation box 32 on the stern side is on the sea bottom, the inner box 5 containing minerals in the operation box 31 near the water surface is hoisted to the cabin near the bow of the surface mother ship 1 by the heavy boom 7, the outer box 9 of the operation box 31 is hoisted to the surface mother ship 1, the displacement 4 in the running box 32 at the stern of the mother ship 1 is taken out by the underwater mining machine and the mining machine, and the displacement 4 is hoisted out from the cabin at the bow of the mother ship 1 and connected to the cable 2 to freely sink, the operation box 32 at the stern side of the surface mother ship 1 can be lifted to the vicinity of the water surface, the outer box body 9 in the operation box is lifted to the stern of the surface mother ship 1, and (3) removing the restraint of the displacement 4 and the cable 2 at the bow side of the mother ship 1 on the water surface through an underwater mining machine and a concentrating machine, and finally withdrawing the cable 2.
