Mining equipment for rare earth resource mud in deep sea and same mining method

摘要

To extract rare earth resource mud in a deep sea capable of safely mining and landing by coping with spread of deep sea rare earth resources mud layer.SOLUTION: The container for a mining room made of a steel box whose lower side is released, the container 10 made of a steel box suspended from a work vessel on the sea surface, the lower end can move in the axial direction from the ceiling portion of the container for a mining chamber 10 in the horizontal direction A lifting flow generating means for raising the mud of the sea bed from the lower end opening together with water is provided in the landing sacrifice pipe 3 The container for excavation room 10 is connected to the lower end portion of the lid duct 3 so as not to drop off and the lift pipe 3 is withdrawn from the work ship toward the bottom of the water so that it is put on the bottom of the water In addition, the lower end of the mantle pipe 3 can be inserted into the muddy ground on the surface of the ocean floor in a state where the container 10 for a mining room is in a bottom.BACKGROUND OF THE INVENTION
