[Problem] deep rare resources corresponding to the spread of the mud, mining safety, can be mined in deep mud pumping mud rare resources. The lower case 10 made of steel container for release [solution] the mining chamber, suspended from a barge on the sea surface, the lower end of the ceiling portion can move in an axial direction from the mining chamber vessel 10 relative horizontal movement is restricted by a hollow cylindrical pumping and withdrawal pipe 3 is inserted, the tube 3 is pumped mud, the lower end opening of the water rising from the sea bottom and provided with means for increasing the flow, the mining chamber container 10, lifting the lower end of the mud pipe 3 which is connected to the non-slipping, pumping water from the bottom of the pipe 3 is delivered toward the bottom by the mud work barge is also such, pumping the slurry pipe 3, the mining chamber 10 at the lower end to the bottom surface of the container is inserted into the seabed become muddy ground.
