Description

Technical Field

[0001] The present invention relates to the technical field of mining systems, and in particular to a working method of a mining system. Background Art

[0002] With economic development, human demand for mineral resources is growing. In order to solve the problem of insufficient supply of mineral resources on land, humans began to explore the ocean for various mineral resources. The international seabed area is the common property of mankind. It contains extremely rich mineral resources, such as polymetallic nodules, cobalt-rich crusts, polymetallic sulfides and other mineral resources. It is the most important successor resource for mankind in the future.

[0003] Polymetallic nodules are mostly distributed on the deep seabed at 4000m-6000m. Therefore, during the operation of the mining system, the mining vehicle collects the polymetallic nodules from the seabed, transports the minerals to the ore storage box through a conveying hose, and then the ore storage box transports the minerals to the mining ship through the ore lifting riser.

[0004] In this mining system, the length of the ore-raising riser will reach several thousand meters. Since it is difficult to accurately predict the weather in deep sea areas, it is inevitable to encounter emergencies such as bad weather during the mining process, which makes it impossible to carry out mining continuously. The ore-raising riser needs to be recovered to avoid bad weather. Since it takes a long time to recover all the ore-raising risers to the mining ship, they are likely to be damaged due to untimely recovery, affecting the use of the mining system.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0053] Embodiment 1

[0054] This embodiment provides a working method of a mining system, which is used to achieve the purpose of quickly processing the ore-raising pipeline and improving the safety of the ore-raising pipeline.

[0055] like Figure 1 As shown, the mining system includes a mining ship 1, a mineral lifting device, an ore lifting pipeline 3 and an ore storage box 4. The mineral lifting device is installed on the mining ship 1, one end of the ore lifting pipeline 3 is connected to the mineral lifting device, and the other end is connected to the ore storage box 4.

[0056] It should be noted that, in the present embodiment, the mining system is used to mine mineral resources on the seabed. Of course, in other embodiments, the mining system can also be used to mine mineral resources in water bodies such as rivers and lakes, which is not limited here.

[0057] Specifically, the mining vessel 1 is provided with a tower platform 11, and a moon pool 12 is provided at the lower part of the mining vessel 1. The moon pool 12 is located directly below the tower platform 11, and provides a channel for lowering and recovering structures such as the ore raising pipeline 3 and the ore storage box 4.

[0058] Furthermore, the mineral lifting device includes a mineral lifting main machine and a telescopic pipe 21, the mineral lifting main machine is fixedly mounted on the tower platform 11, and the ore-raising pipe 3 is connected to the mineral lifting main machine through the telescopic pipe 21; illustratively, the ore-raising pipe 3 is connected to the telescopic pipe 21 through a flange. When the mining system is in the working position, one end of the ore-raising pipe 3 connected to the telescopic pipe 21 is located underwater. The ore-raising pipe 3 is connected to the mineral lifting main machine through the telescopic pipe 21, and the ore-raising pipe 3 is transported and stored; at the same time, the telescopic pipe 21 can also compensate for the position change of the mining ship 1 and the ore-raising pipe 3 caused by water fluctuations such as waves, so as to ensure that the ore-raising pipe 3 and the ore storage box 4 will not be affected by water fluctuations such as waves.

[0059] Furthermore, the mineral lifting main machine includes a diverter 22 to divert the slurry through the diverter 22. The end of the telescopic pipe 21 away from the ore-lifting pipe 3 is connected to the diverter 22 through a first flexible joint 23, thereby facilitating compensation for position changes of the mining ship 1 and the ore-lifting pipe 3 caused by water fluctuations such as waves.

[0060] Furthermore, the ore-raising pipe 3 is connected to the ore storage box 4 via the second flexible joint 31, thereby facilitating compensation for position changes of the mining vessel 1 and the ore-raising pipe 3 caused by water fluctuations such as sea waves.

[0061] Furthermore, the ore lifting pipeline 3 is provided with an injection valve 32 for emergency injection of seawater.

[0062] Furthermore, a suction pump and an ore silo are provided in the ore storage box 4 for conveying the nodules collected by the mining vehicle and temporarily storing them.

[0063] Furthermore, a foot 41 is provided at the bottom of the ore storage box 4. When the ore lifting pipe 3 is separated from the mining ship 1, the ore storage box 4 is landed on the seabed by lowering the ore lifting pipe 3. The foot 41 can be inserted into the seabed (including seabed sediments) on the seabed to fix the ore storage box 4 and the ore lifting pipe 3 to avoid being affected by wind and waves. Exemplarily, there are four foots 41, and the four foots 41 are respectively arranged around the ore storage box 4 to ensure that the ore storage box 4 is firmly fixed. Of course, the number of foots 41 can also be set to other values, and this embodiment does not limit the number and distribution of foots 41. Of course, the foot 41 can also be replaced by a suction anchor or a positioning pile controlled by a hydraulic cylinder, which can also achieve the purpose of fixing the ore storage box 4 and the ore lifting pipe 3.

[0064] Specifically, the telescopic pipe 21 is provided with a tension ring 211 , and the tension ring 211 is connected to a pulley of a tensioning device installed on the tower platform 11 through a pull rope, thereby achieving tensioning and stabilizing operation of the ore lifting pipe 3 .

[0065] Furthermore, a release device 212 is provided between the ore raising pipe 3 and the mineral lifting device, and the release device 212 is used to lock or unlock the ore raising pipe 3 and the mineral lifting device. The ore raising pipe 3 and the mineral lifting device are locked or unlocked by the release device 212, which improves the convenience of connecting or separating the ore raising pipe 3 and the mineral lifting device. Specifically, the release device 212 is provided between the telescopic pipe 21 and the ore raising pipe 3.

[0066] It should be noted that the structure and working principle of the release device 212 are all prior art, which will not be described in detail here. Furthermore, the structure and working principle of the mining system are all prior art, which will not be described in detail here.

[0067] like Figure 2 As shown, the mining system working method includes the following steps:

[0068] S1. When the mining system is in the working position, the floating member 5 is installed on the ore lifting pipeline 3; when the mining system is in the working position, the mining vessel 1 is located on the water, and the ore storage box 4 is located on the bottom of the water;

[0069] It can be understood that the mining system is considered to be in a working position when the mining vessel 1 is driven to a designated sea area, and then the ore lifting pipe 3 and the ore storage box 4 are lowered so that the ore storage box 4 is located on the underwater ground, and when all parts of the mining system are in a state of being able to work normally.

[0070] S2, separating the ore lifting pipeline 3 from the mineral lifting device, so that the ore lifting pipeline 3 is suspended in the water under the buoyancy of the floating member 5.

[0071] The working method of the mining system of this embodiment is that when the mining system is in the working position, the floating member 5 can be installed on the ore-raising pipe 3, and then the ore-raising pipe 3 can be separated from the mineral lifting device, so that the ore-raising pipe 3 is suspended in the water under the buoyancy of the floating member 5, thereby realizing rapid processing of the ore-raising pipe 3. Compared with the prior art, when encountering emergencies such as bad weather, it can achieve rapid response and improve the safety of the ore-raising pipe 3.

[0072] Exemplarily, the floating member 5 is a floating ball, the center of which is provided with a mounting hole, one end of the ore-raising pipe 3 is inserted into the mounting hole, and is fixedly connected to the ore-raising pipe 3 by a locking member such as a locking pin, so as to limit the movement of the floating member 5 relative to the ore-raising pipe 3. Of course, the floating member 5 can also be set to other shapes or structures, and the floating member 5 can also be installed on the ore-raising pipe 3 by other installation methods in the prior art, which are not limited here.

[0073] Optionally, when the floating member 5 is installed on the ore-raising pipe 3, the axis of the ore-raising pipe 3 is made to coincide with the vertical center line of the floating member 5. Such an arrangement is conducive to balancing the force on the ore-raising pipe 3 and protecting the ore-raising pipe 3.

[0074] Furthermore, the floating member 5 is installed on the ore lifting pipeline 3, including the following steps:

[0075] The floating member 5 is installed at a preset position of the ore-raising pipe 3, and the part of the ore-raising pipe 3 above the floating member 5 is removed, so that when the ore storage box 4 falls on the bottom of the water, the distance between the floating member 5 and the horizontal plane (including the sea level 100) is the preset distance.

[0076] It should be noted that the value of the preset spacing can be set through experiments or the experience of those skilled in the art. In other words, the preset spacing is a known value and is not limited here. It can be understood that when the spacing between the floating member 5 and the horizontal plane is the preset spacing, the safety of the ore-raising pipeline 3 is higher. For example, the preset spacing is approximately one wavelength, so that the ore-raising pipeline 3 maintains a certain tension and remains in a vertical state, which better protects the ore-raising pipeline 3.

[0077] The structure of the ore-raising pipeline 3 and the method of dismantling part of the ore-raising pipeline 3 to shorten the length of the ore-raising pipeline 3 are both existing technologies in the art and will not be described in detail here.

[0078] Furthermore, after the ore-raising pipe 3 is separated from the mineral lifting device, the ore-raising pipe 3 is straightened by the floating member 5 and the ore-accumulating box 4. Specifically, by controlling the buoyancy of the floating member 5, the ore-raising pipe 3 is straightened by the floating member 5 and the ore-accumulating box 4 on the basis that the ore-accumulating box 4 can fall on the bottom of the water, so that the ore-raising pipe 3 is better protected.

[0079] Optionally, before step S1, the mining system working method further includes the following steps:

[0080] The ore lifting pipe 3 is lifted so that the end of the ore lifting pipe 3 connected to the telescopic pipe 21 is raised to the main deck of the mining ship 1 (such as Figure 3 shown).

[0081] Such an arrangement makes it easier for workers to complete the installation of the floating member 5 on the mining vessel 1, saving time and effort and providing higher safety.

[0082] It should be noted that the devices and methods for lifting and lowering the ore raising pipeline 3 are prior arts in the art and will not be described in detail here.

[0083] Furthermore, when the end of the ore-raising pipe 3 connected to the telescopic pipe 21 is raised to the main deck of the mining ship 1 , the ore-raising pipe 3 is fixed, which can improve the convenience of installing the floating member 5 .

[0084] Furthermore, when one end of the ore lifting pipe 3 connected to the telescopic pipe 21 is raised to the main deck of the mining ship 1 , the tension ring 211 is first removed to facilitate the installation of the floating member 5 .

[0085] Furthermore, after the ore-raising pipe 3 is lifted and the floating member 5 is installed on the ore-raising pipe 3, the mining system working method further includes the following steps:

[0086] After the ore-raising pipeline 3 is lowered by a preset distance, the ore-raising pipeline 3 is separated from the mineral lifting device (such as Figure 4 shown).

[0087] So set up, such as Figure 5 As shown, on the one hand, the ore storage box 4 can be dropped to the bottom of the water at a safe speed to ensure the safety of the ore storage box 4, and on the other hand, it is easy to control the position of the ore storage box 4 when it falls on the bottom of the water, so that the ore lifting pipeline 3 can be docked with the mineral lifting device again.

[0088] It should be noted that the value of the preset distance can be set through experiments or the experience of those skilled in the art. In other words, the preset distance is a known value and is not limited here.

[0089] When lowering the ore-raising pipeline 3 , the ore-raising pipeline 3 is slowly lowered, which is beneficial to evenly stress the ore-raising pipeline 3 and protects the ore-raising pipeline 3 .

[0090] Optionally, the ore lifting pipeline 3 is separated from the mineral lifting device, comprising the following steps:

[0091] The release device 212 is controlled to be unlocked so that the ore raising pipe 3 is separated from the mineral lifting device. The release device 212 is used to lock or unlock the ore raising pipe 3 and the mineral lifting device, thereby improving the convenience of separating the ore raising pipe 3 from the mineral lifting device.

[0092] Further, in step S2, after the ore lifting pipeline 3 is separated from the ore lifting device, Figure 6 As shown, the ore storage box 4 falls on the underwater ground (such as the seabed mud line 200). Specifically, the buoyancy of the floating member 5 can be controlled so that after the ore pipe 3 is separated from the mineral lifting device, the ore storage box 4 falls on the underwater ground under the combined action of gravity and the buoyancy of the floating member 5, and then the ore pipe 3 is fixed by the ore storage box 4 to prevent the ore pipe 3 from shifting under the action of the ocean current, so that the ore pipe 3 can be docked with the mineral lifting device again.

[0093] Furthermore, when the ore box 4 falls on the underwater ground, the foot 41 is inserted into the underwater ground. Specifically, the buoyancy of the floating member 5 can be controlled so that the ore pipe 3 and the ore box 4 can be slowly lowered under the combined action of gravity and the buoyancy of the floating member 5, so that the ore box 4 contacts the seabed at a slow speed, and the foot 41 is inserted into the underwater ground to prevent the ore box 4 from slipping or overturning, and to ensure that the ore box 4 is firmly fixed, so that the ore box 4 and the ore pipe 3 can be stationed on the seabed, which can not only prevent the ore box 4, the ore pipe 3 and the filling valve 32 from being lost under the action of the ocean current, causing economic losses, but also ensure that the position of the ore pipe 3 will not change too much, so that the ore pipe 3 can be easily docked with the mineral lifting device again.

[0094] Figure 7 This is a detailed flow chart of the working method of the mining system provided in this embodiment. Figure 7 The working method of the above mining system is introduced in detail.

[0095] The mining system working method includes the following steps:

[0096] S10, when the mining system is in the working position, the ore raising pipe 3 is lifted so that the end of the ore raising pipe 3 connected to the telescopic pipe 21 is raised to the main deck of the mining ship 1. When the mining system is in the working position, the mining ship 1 is located on the water, and the ore storage box 4 is located on the bottom of the water.

[0097] S20, installing the floating member 5 on the ore-raising pipeline 3, and making the axis of the ore-raising pipeline 3 coincide with the vertical center line of the floating member 5.

[0098] S30, after the ore-raising pipe 3 is lowered by a preset distance, the release device 212 is controlled to unlock, so that the ore-raising pipe 3 is separated from the mineral lifting device.

[0099] S40, after the ore-lifting pipe 3 is separated from the mineral lifting device, the ore storage box 4 falls on the underwater ground; when the ore storage box 4 falls on the underwater ground, the foot 41 is inserted into the underwater ground, and the distance between the floating member 5 and the horizontal plane is a preset distance, and the ore-lifting pipe 3 is straightened by the floating member 5 and the ore storage box 4.

[0100] The working method of the mining system of this embodiment can realize the rapid release of the ore-raising pipe 3 and the ore-accumulating box 4 in the face of severe sea conditions, thereby reducing the time cost. By leaving the ore-raising pipe 3 and the ore-accumulating box on the seabed, the space on the mining ship is released, providing more storage space for other mining systems, and saving the construction cost of the mining ship to a certain extent.

[0101] Embodiment 2

[0102] The difference between this embodiment and the first embodiment is that:

[0103] The mining system also includes a ore-raising substitute pipeline and an ore-accumulating substitute box connected to the ore-raising substitute pipeline.

[0104] Furthermore, if Figure 8 As shown, the mining system working method includes the following steps:

[0105] S100, installing the floating substitute component at the end of the ore-lifting substitute pipeline away from the ore-accumulating substitute box.

[0106] S200, placing the ore-raising substitute pipeline and the ore-accumulating substitute box connected thereto underwater, so that the ore-raising substitute pipeline is suspended in the water under the buoyancy of the floating substitute component.

[0107] S300, when the mining system is in the working position, if the ore-raising pipe 3 connected to the mineral lifting device and / or the ore-accumulating box 4 connected to the ore-raising pipe 3 fails, the floating member 5 is installed on the ore-raising pipe 3; when the mining system is in the working position, the mining vessel 1 is located on the water, and the ore-accumulating box 4 is located on the bottom of the water.

[0108] S400 , separating the ore lifting pipeline 3 from the mineral lifting device, so that the ore lifting pipeline 3 is suspended in the water under the buoyancy of the floating member 5 .

[0109] S500, connect the mineral lifting device to the ore lifting substitute pipeline.

[0110] Through the above steps, the ore lifting substitute pipeline and ore storage substitute box are laid out in the mining area in advance, and then when the ore lifting pipeline 3 and / or the ore storage box 4 fails, the ore lifting pipeline 3 can be quickly disconnected and the ore lifting substitute pipeline can be connected to ensure the smooth progress of the mining operation. Due to the relatively stable environment of the deep sea, the ore lifting pipeline 3 and the ore storage box 4 can be deployed at multiple points, thereby improving the mining efficiency.

[0111] It should be noted that the structure of the ore raising pipeline 3 is the same as that of the ore raising substitute pipeline, and the structure of the ore accumulation box 4 is the same as that of the ore accumulation substitute box. In other words, the ore raising pipeline 3 and the ore raising substitute pipeline are redundant with each other, and the ore accumulation box 4 and the ore accumulation substitute box are redundant with each other. It can also be understood that the pipeline connected to the mineral lifting device is the ore raising pipeline 3, and the pipeline not connected to the mineral lifting device is the ore raising substitute pipeline.

[0112] Furthermore, a plurality of ore-raising substitute pipelines, ore-accumulating substitute boxes and floating substitute components are provided, and the ore-accumulating substitute boxes and floating substitute components are connected to the ore-raising substitute pipelines in a one-to-one correspondence.

[0113] Specifically, when the ore-raising substitute pipeline is connected to the mineral lifting device, if the ore-raising substitute pipeline and / or the ore-storage substitute box connected to the ore-raising substitute pipeline fails, the floating substitute component is installed on the ore-raising substitute pipeline, and then the ore-raising substitute pipeline is separated from the mineral lifting device, so that the ore-raising substitute pipeline is suspended in the water again under the buoyancy of the floating substitute component, and then the mineral lifting device is connected to other ore-raising substitute pipelines.

[0114] It should be noted that how to determine whether the ore-raising pipe 3 connected to the mineral lifting device and / or the ore storage box 4 connected to the ore-raising pipe 3 is faulty is a prior art in the art and will not be described in detail herein.

[0115] In other embodiments, the ore raising substitute pipeline, the ore accumulation substitute box and the floating substitute part can also be provided with one. Of course, the structure of the ore raising pipeline 3 and the ore raising substitute pipeline can also be different, and the structure of the ore accumulation box 4 and the ore accumulation substitute box can also be different.

[0116] Note that the above are only preferred embodiments of the present invention and the technical principles used. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
