Description

Technical Field

[0001] The invention relates to the field of sea sand weight estimation, and in particular to a method, device, medium and product for estimating the weight of sea sand after mining. Background Art

[0002] Sea sand is a valuable marine resource and the second largest marine mineral resource after oil and natural gas, with abundant reserves in the nearshore and continental shelf areas. With the shortage of terrestrial sand resources, stricter regulatory policies and increased attention to marine environmental protection, sea sand mining has gradually become legalized and normalized.

[0003] At present, before the auction of sea sand resources, it is necessary to explore the scale of sea sand resource reserves, determine the resource range and elevation, that is, the recoverable resource reserves (measured in volume). When auctioning sea sand, blocks are usually designated and volume reserves are determined. How to control the amount of mining has become a key issue. Excessive exploitation of sea sand will not only cause the loss of mineral resources, but also change the natural conditions of the seabed, causing imbalance and damage to the ecological environment.

[0004] The actual weight of sea sand varies with storage conditions and various unforeseen factors. After the auction is completed, the transfer and settlement weight of the sea sand will be based on the actual measured weight without considering factors such as moisture, and the buyer must unconditionally agree to the measured quantity. The reserves of sea sand auctioned are usually calculated based on the seabed ore, which contains mud and moisture. The sea sand mined ashore is washed and becomes ore dressing, and its water content is also different from the original state on the seabed. How to convert the volume of seabed ore into ore dressing weight (actual weight of mined sea sand) for the purpose of supervising the amount of sea sand mined is a technical problem that needs to be solved urgently. Summary of the invention

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide a method, device, medium and product for estimating the weight of sea sand after mining, aiming to control the mining volume according to the actual weight of the mined sea sand.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1 As shown, the method for estimating the weight of sea sand after mining in this embodiment includes:

[0038] Step S1: Obtain the volume, natural density, water content and mud content of seabed sand mines in multiple geological blocks; wherein the multiple geological blocks are obtained by dividing the target blocks according to preset rules.

[0039] As a specific implementation method, the volume of the seabed sand mine in each geological block is obtained according to the area and elevation of the seabed sand mine in each geological block. The natural density and water content of the seabed sand mine in each geological block are tested by the geological block method. The mud content of the seabed sand mine in each geological block is obtained by testing the mud content of the dried sea sand sample of the seabed sand mine in each geological block.

[0040] In practical applications, during the resource exploration stage, the natural density of seabed sand ore (kg / m 3) and water content C wi (%).

[0041] Specifically, the method for determining the natural density is as follows:

[0042] (1) Cut the original sample with a thickness greater than the height of the ring knife by 0.3 cm to 0.5 cm. Apply a thin layer of vaseline to the ring knife and place it on the soil sample, with the center of the circle aligned with the center of the soil sample;

[0043] (2) Press the knife ring vertically downward, and use a wire saw to cut off the outer sample until the sample sticks out of the knife ring. Cut off the remaining sample at both ends of the knife ring, wipe the outer wall of the knife ring clean, and weigh it with a balance with a sensitivity of 0.01g;

[0044] The formula for calculating the natural density of sediment is: Where ρ is the original sample density, in g / cm 3 , m w is the weight of the wet sample, in g; V is the volume of the cutter ring, in cm 3 .

[0045] Specifically, the method for determining the water content includes:

[0046] (1) Take 15 to 30 g of a representative sample and place it in a weighing box. Close the box lid and weigh the box plus the moistened soil to an accuracy of 0.01 g.

[0047] (2) Open the box cover, place the sample in the box into the oven, and dry it at a temperature of 100-105°C until it reaches a constant weight. The drying time for clay and silt shall not be less than 8 hours, and for sandy soil shall not be less than 6 hours. For soil containing organic matter exceeding 5% of the dry soil weight, the temperature should be controlled at 65-70°C and dried until it reaches a constant weight.

[0048] (3) Take the dried sample out of the oven, cover the box, place it in a drying container and cool it to room temperature. Weigh the box plus dry soil to an accuracy of 0.01 g.

[0049] The formula for calculating the water content of sediment is: Among them, C w is the water content, in %; m w is the weight of the wet (original) sample, in g; m d is the dry sample weight in g.

[0050] Take samples from various geological blocks and test the mud content C of dry samples (dried sea sand samples) m (%) specifically include:

[0051] (1) Sampling: When sampling on the sea sand pile, the sampling locations should be evenly distributed. The minimum sampling quantity is 4.4 kg.

[0052] (2) Sample processing: Place the sample on a flat plate, mix it evenly while it is wet, and pile it into a round cake with a thickness of about 20 mm. Then divide the round cake into four approximately equal parts along two mutually perpendicular diameters, take two of the diagonal parts, mix them again, and pile them into round cakes again.

[0053] (3) Drying: Reduce the sample to about 1100 g, place it in a drying oven at (105±5) to a constant weight, and after cooling to room temperature, divide it into two approximately equal portions for later use.

[0054] (4) Weigh the sample: Weigh 500g of the sample, accurate to 0.1g. Pour the sample into a washing container, add clean water, make the water level about 150mm higher than the sample surface, mix thoroughly, soak for 2h, and then wash the sample in water by hand to separate the sediment, silt and clay from the sand. Slowly pour the turbid water onto the 1.18mm and 75μm sieves (1.18mm sieve on top of the 75μm sieve) to filter out particles smaller than 75μm. Both sides of the sieve should be moistened with water before the test, and care should be taken to avoid the loss of sand during the entire process.

[0055] (5) Repeat the washing: Pour clean water into the water container and repeat the above steps until the water in the container is clear.

[0056] (6) Drying: Shake to fully wash away particles smaller than 75 μm. Then put the particles remaining on the two sieves and the cleaned sample in the container into an enamel tray and place it in a drying oven at (105±5)℃ to dry to constant weight. Take it out and cool it to room temperature before weighing the sample.

[0057] The formula for the mud content of sea sand is: C m =(G0-G1) / G0×100%; where C m is the mud content of sea sand; G0 is the drying weight of sand before the test (g); G1 is the drying weight of sand after the test (g).

[0058] The block method is to divide the ore body into different small blocks according to the geological characteristics and conditions of the ore deposit (such as ore grade, natural type, reserve category, technical conditions for ore mining and hydrogeological conditions, etc.) or exploration projects. For each block, the reserves can be estimated by the arithmetic average method.

[0059] Sea sand resources are generally estimated using the geological block method (original ore), usually in terms of volume V (m 3 ) indicates that its calculation formula is as follows:

[0060] V i =S i ×h i ;

[0061] V=∑V i ;

[0062] Where: V i ——Sea sand resources / reserves (original ore) in block i (m 3 );

[0063] S i ——The area of ​​the sea sand ore layer in the i-th block (m 2 );

[0064] h i ——Thickness of sea sand layer in block i (m);

[0065] V——Sea sand resources / reserves (original ore) (m 3 ).

[0066] Step S2: Calculate the weight of dry sea sand in the target area according to the volume, natural density, water content and mud content of the seabed sand in each geological block.

[0067] As a specific implementation method, the formula

[0068] Calculate the weight of dry sea sand ore of each geological block, that is, the weight of dry sea sand ore (m) after desludging in each geological block.

[0069] The weight of dry sea sand ore of the seabed sand ore in each geological block is added together to obtain the weight of dry sea sand ore in the target block.

[0070] Specifically, the formula for adding the weight of dry sea sand ore of each geological block is: m = ∑m i .

[0071] Where: m i ——Sea sand resources / reserves of block i (dry sea sand ore) (kg);

[0072] V i ——Sea sand resources / reserves (original ore) in block i (m 3 );

[0073] ρ i ——Density of sea sand layer in block i (kg / m 3 );

[0074] C wi ——Water content of sea sand ore layer in block i (%);

[0075] C mi ——Mud content of sea sand ore layer in the ith block (%).

[0076] Step S3: Obtain the average water content of the sea sand at the time of transfer and settlement of the seabed sand mine in the target block.

[0077] As a specific implementation method, the initial water content of the sea sand in each layer at the time of handover and settlement of the seabed sand mine in the target block is obtained; based on the initial water content of the sea sand in each layer, the average water content of the sea sand at the time of handover and settlement of the seabed sand mine in the target block is calculated.

[0078] Step S4: Calculate the actual mined sea sand weight of the seabed sand mine in the target block according to the average water content of the sea sand and the weight of the dry sea sand mine at the time of transfer and settlement of the seabed sand mine in the target block.

[0079] As a specific implementation method, the formula M=(1+C wm )×m is used to calculate the actual weight of the mined sea sand of the seabed sand mine in the target block; where M is the actual weight of the mined sea sand of the seabed sand mine in the target block; m is the weight of the dry sea sand ore of the seabed sand mine in the target block; C wm The average water content of sea sand at the time of transfer and settlement of the seabed sand mine in the target block.

[0080] In practical applications, when sea sand is transferred and settled, it is necessary to re-measure the water content because it has been placed for a period of time after being collected from the sea, resulting in water loss, and its average water content C is obtained. wm (%) (When the sea sand is transferred and settled, samples from different layers are taken to test the water content and the average value is taken). The weight of sea sand actually mined from a sea sand deposit with a volume reserve of V should be:

[0081]

[0082] According to the detection results of the volume, natural density, water content and mud content of the seabed sand ore, the present invention can obtain the actual mined sea sand weight of the seabed sand ore in the target block before the seabed sand ore in the target block is mined. During the mining process, when the weight of the mined sea sand reaches the actual mined sea sand weight, the mining of the seabed sand ore in the target block is stopped to avoid excessive mining of sea sand. Further, the protection of the natural conditions of the seabed of the target block is achieved.
