  • Patent number: 11150059
    Abstract: A deep-sea mining device is sunk to a seabed mining area. A window of an exploding wire unit of a pulse exploding wire group is aligned to an exploding area. A strong pulse current is applied to an exploding wire of the exploding wire unit by an intense pulse power supply, and the exploding wire of the exploding wire unit and seawater in an exploding wires area are vaporized to generate shock waves, thereby breaking rocks through the impact of the seawater. The instantaneous high pressure causes the shock waves to crush the ore bed, and the pressure of the shock waves generated by the explosion of the exploding wire can be controlled by controlling the pulse voltage and current, so as to control the crushing head to crush rocks with different thicknesses.
