The invention discloses a deep-sea poly-metallic nodule near-bottom dragging mining system and method. The deep-sea poly-metallic nodule near-bottom dragging mining system includes a surface support ship, an underwater near-bottom mining platform, and a seabed collection system; a tower crane on the surface support ship is equipped with a main ore lifting pipeline; the lower end of the main ore lifting pipeline is connected to the underwater near-bottom mining platform; the underwater near-bottom mining platform is connected to the seabed collection system through a dragging pipeline; the seabed collection system includes multiple sets of articulated hydraulic collection units; and the multiple sets of hydraulic collection units form a wide collection head. The deep-sea poly-metallic nodule near-bottom dragging mining method is as follows: the underwater near-bottom mining platform sends high-pressure water to the seabed collection system for high-pressure water jet collection of ore;and the underwater near-bottom mining platform sucks the ore back, and then sends the ore to the main ore lifting pipeline, so that the ore is lifted to the surface support ship on the surface of thesea. On the basis of solving the problem of insufficient power of the collection system and the adaptability of micro-terrain, the invention can greatly increase the width of the collection head and improve the mining efficiency.

    本发明公开了一种深海多金属结核近底拖曳采矿系统及方法,本系统包括水面支持船舶、水下近底采矿平台、海底采集系统;水面支持船舶上的塔吊吊装有主扬矿管道,主扬矿管道的下端与水下近底采矿平台相接,水下近底采矿平台通过拖拽管道与海底采集系统相连接,海底采集系统包括多组相互铰接的水力式采集单元,多组水力式采集单元组成宽幅采集头;本方法为:由水下近底采矿平台将高压水送到海底采集系统内,进行高压水射流式采集矿石,并由水下近底采矿平台将矿石抽吸回,再将矿石送到主扬矿管道内,使矿石被提升至海面的水面支持船舶上。本发明解决采集系统动力不足问题和微地形适应能力基础上,可以大幅提升采集头的宽度,提高采矿效率。
