Embodiment 1

[0042] see Figure 1 to Figure 4 , a deep-sea polymetallic nodule ore-collecting operation method according to an embodiment of the present invention, comprising the following steps:

[0043] Step S1: Divide the polymetallic nodule mining area 100 to be collected into several small blocks 101 according to the distribution of polymetallic nodules and / or seabed topography;

[0044] Step S2: Place the seabed ore collection hopper 1 in the middle of the above-mentioned divided small block 101, and connect the feed port 11 of the seabed ore collection hopper 1 with the transportation hose 2 of the seabed polymetallic nodule collection vehicle 3 through the transportation hose 2 The heads 32 are connected to each other, and polymetallic nodules are collected within the corresponding small block 101 through the seabed polymetallic nodule collecting vehicle 3, and the polymetallic nodules are transported to the seabed ore collection hopper 1 through the transport hose 2;

[0045] Step ...

Embodiment 2

[0056] see Figure 5 to Figure 8 , a deep-sea polymetallic nodule ore collection system adopted by the deep-sea polymetallic nodule collection operation method of the present invention, the deep-sea polymetallic nodule collection system mainly includes a mining ship 5, a seabed ore collection hopper 1 and a seabed polymetallic nodule collection car 3. Wherein, a feed port 11 and a discharge port 12 are arranged on the seabed ore collecting hopper 1, and the mining ship 5 is detachably connected with the discharge port 12 through a conveying pipeline 4; It is detachably connected to the feed opening 11 via a delivery hose 2 .

[0057] The above-mentioned deep-sea polymetallic nodule collecting system is detachably connected to the mining ship 5 and the outlet 12 of the seabed ore collecting hopper 1 through the conveying pipeline 4, and the seabed polymetallic nodule collecting vehicle 3 is connected to the seabed collecting hopper through the conveying hose 2. The feed port ...

Abstract

The invention discloses a deep sea polymetallic nodule ore collection operation method and an ore collection system. The ore collection operation method comprises the following steps that S1, a polymetallic nodule mining area to be collected is divided into a plurality of small blocks according to the polymetallic nodule distribution condition and / or the submarine topography; S2, seabed ore collection hoppers are placed in the middle portions of the small blocks, feeding ports of the seabed ore collection hoppers are connected with a seabed polymetallic nodule collection vehicle through conveying hoses, the seabed polymetallic nodule collection vehicle collects polymetallic nodules in the corresponding small block ranges, and meanwhile, the polymetallic nodules are conveyed to the seabed ore collection hoppers through the conveying hoses; and S3, after the collection of the polymetallic nodules in one small block is completed, the step S2 is repeated until the collection of the polymetallic nodules in all small blocks in the polymetallic nodule mining area is completed. According to the ore collection operation method, the relative movement range between the collection vehicle and the ore collection hoppers during collection can be reduced, and the stable ore conveying state can be kept.

Description

technical field [0001] The invention relates to the technical field of ore collection and collection of deep-sea polymetallic nodules, in particular to a deep-sea polymetallic nodule ore collection operation method and an ore collection system. Background technique [0002] In the current deep-sea mining system, the commonly used mining method is to connect a deep-sea mining vehicle with a conveying hose of several hundred meters, and the conveying hose is connected to a hard pipe several kilometers long by a relay station, and the hard pipe is connected to the ship. Usually hinged. [0003] Because the area of ​​the seabed polymetallic nodule mining area is generally very large, the existing mining methods usually require the seabed polymetallic nodule collecting vehicle to collect polymetallic nodules in a larger mining range. The moving distance between the ore hoppers is relatively long, resulting in an increase in the relative movement between the collecting vehicle an...
