摘要： Described is a deep-sea mining vehicle for taking up mineral deposits from a seabed at great depth, and optionally transporting said deposits to a floating device. The vehicle includes a support frame provided with means for moving the vehicle forward on the seabed, with at least one suction head with an open suction side which is directed toward the seabed and along which the mineral deposits and surrounding water are taken up, and with a temporary storage, connected via a suction conduit to the at least one suction head, for the mineral deposits taken up. The temporary storage includes a container with a front wall, a rear wall, side walls, an upper wall, and a bottom. The temporary storage further includes at the position of the upper wall and connecting to the front wall a first connecting part for the suction conduit, and at substantially the same height and connecting to the rear wall a second connecting part for a discharge conduit for discharge of substantially the sucked-up water. The temporary storage further includes at the position of the bottom and connecting to the interior of the container a third connecting part for a discharge conduit for discharge of substantially the mineral deposits.

摘要： Described is a deep-sea mining vehicle for taking up mineral deposits from a seabed at great depth, and optionally transporting said deposits to a floating device. The vehicle includes a support frame provided with means for moving the vehicle forward on the seabed, a storage for the mineral deposits taken up, and further a suction head with an open suction side which is directed toward the seabed and along which the mineral deposits are taken up. The deep-sea mining vehicle is further provided with a control device for keeping the height of the suction plane within predetermined limits relative to the seabed. The control device makes use of measuring means for obtaining seabed heights at positions which precede the open suction side relative to the direction of movement and which extend over a width of the deep-sea mining vehicle. An actuator which is incorporated in a control circuit adjusts the height of the suction head on the basis of the seabed heights measured at the positions.
