Abstract
Description
Technical Field
[0001] This application relates to the technical field of coal dust control methods, and more specifically, to a coal dust control method, a coal dust control device, a computer-readable storage medium, and an electronic device. Background Technology
[0002] The development of the coal industry is crucial to my country's basic energy security and the sustainable development of thermal power, iron and steel metallurgy, and chemical industries. Its pivotal role in the rapid development of the national economy and its status as my country's basic and primary energy source are unlikely to change in the short term. Over the past decade, with the increasing intelligence, mechanization, and automation of mines, the potential for disasters such as gas, coal dust, and fires has increased. Coal dust, in particular, generated during coal mining and processing, not only poses a significant threat to safe production and occupational health of workers in mining areas but also pollutes the environment and damages the ecosystem. Research on dust removal mechanisms and related technologies remains a key challenge and focus for the scientific and effective control of coal dust in the coal mining and processing industry.
[0003] Currently, the most commonly used methods for coal dust control include closed-loop dust control, curtain dust isolation, spray dust suppression, dust collector dust collection, and inhibitor dust suppression. Many of these coal dust control technologies utilize physical methods, resulting in relatively low removal rates for respirable coal dust. Since the 1960s, chemical dust suppression technology has developed rapidly, becoming a new direction in coal dust control. However, its long-term application in coal mines has been limited. The main reason is that, given the unclear mechanism of action of dust suppressants, the focus on developing dust suppressants through experimental methods and experience has led to poor adaptability and specificity of the agents. This has significantly hindered the development, application, and promotion of coal dust control technology in the coal industry. Summary of the Invention

This includes using one of the following methods: data analysis, statistical methods, machine learning, and artificial intelligence, to determine the relationship between the wetting angle and the sample parameters based on the sample parameters and the corresponding wetting angle to obtain the target relationship.

[0035] This embodiment provides a method for preventing coal dust that runs on a mobile terminal, computer terminal, or similar computing device. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Also, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.
[0036] Figure 2 This is a flowchart of a coal dust control method according to an embodiment of this application. Figure 2 As shown, the method includes the following steps:
[0037] Step S201: Obtain sample parameters corresponding to multiple coal dust samples. The sample parameters include physical parameters and chemical parameters. The physical parameters are used to characterize the physical properties of the coal dust samples, and the chemical parameters are used to characterize the parameters of the wetting agent and / or surfactant used in the wetting test of the coal dust samples.
[0038] Specifically, the above wetting test can be performed using experimental equipment such as a contact angle meter.
[0039] Data on the effect of surfactants on the wettability of coal dust can be collected by using different types and concentrations of surfactants to study the wettability of different coal dust samples. In one alternative approach, the surfactants include at least one of Tween20 and Triton X-100.
[0040] In one specific embodiment, the wetting angles of four samples under surfactants such as Tween 20 and Triton X-100 were measured, and the data obtained are shown in Table 1:
[0041] Table 1
[0042] Coal dust sample number Tweening angle (°) Triton X-100 wetting angle (°) Sample 1 70 80 Sample 2 60 70 Sample 3 50 60 Sample 4 40 50
[0043] In step S201, sample parameters of multiple coal dust samples are obtained, including: obtaining at least one of the following for each coal dust sample: composition, surface functional groups, particle size distribution range, specific surface area, and porosity, to obtain the corresponding physical parameters; obtaining at least one of the following: type of wetting agent, type of surfactant, and concentration of surfactant, to obtain the aforementioned chemical parameters; and arbitrarily combining the aforementioned physical and chemical parameters to obtain multiple sample parameters. The composition, surface functional groups, particle size distribution range, specific surface area, and porosity of coal dust samples are all properties of coal dust. The physical and chemical properties of different coal dust samples, as well as parameters such as the concentration and type of different wetting agents, can be measured to study their influence on wettability.
[0044] Step S202: Determine the wetting angle of the coal dust sample corresponding to the above sample parameters in the above wetting test;
[0045] Specifically, the wetting performance of coal dust is determined based on the size of the wetting angle.
[0046] In one specific embodiment, three different types of coal (coal A, coal B, and coal C) were selected, and their particle size distribution, specific surface area, and porosity were measured. Correlation analysis was then performed between these properties and the wetting angle, and relevant data were collected. The data are shown in Table 2.
[0047] Table 2

[0049] Three different types of surfactants (surfactant A, surfactant B, and surfactant C) were selected to test the wetting properties of coal dust samples. The test data were statistically analyzed, and relevant information was collected. Different types of surfactants have different effects on the wetting properties of coal dust; therefore, it is necessary to select an appropriate surfactant based on specific circumstances. The data are shown in Table 3.

[0052] The wetting angles of different coal dust samples under different wetting agents were measured. For example, the wetting angles of four samples were measured, and the data are shown in Table 4.
[0053] Table 4
[0054] Coal dust sample number Wetting angle (°) Sample 1 90 Sample 2 80 Sample 3 75 Sample 4 70
[0055] To determine the relationship between the wettability of coal dust and time, one option involves determining the wetting angle of the coal dust samples corresponding to multiple sample parameters in the aforementioned wetting test. This includes performing the aforementioned wetting test on the coal dust samples corresponding to each of the aforementioned physical parameters under the conditions of the corresponding chemical parameters, and obtaining the corresponding wetting angle. In practical applications, the wettability of coal dust decreases with increasing time; therefore, it is necessary to select appropriate prevention and control methods for prompt treatment. The wettability of coal dust has a relatively small correlation with ash content, moisture content, and volatile matter content; therefore, different prevention and control measures can be adopted for different coal types.
[0056] In another specific embodiment, three coal dust samples with different particle sizes (coal dust A, coal dust B, and coal dust C) were selected and placed in a laboratory with a humidity of 70%. Hourly changes in humidity, temperature, and coal dust mass were recorded, and relevant data were collected. The data are shown in Table 5.
[0057] Table 5
[0058] sample Time (h) humidity(%) Temperature (°C) Coal dust mass (g) Coal dust A 1 70.2 25.1 50 2 70.5 25.2 50.5 3 70.8 25.3 51 Coal dust B 1 70.3 25 49.8 2 70.6 25.1 50.2 3 70.9 25.2 50.5 Coal dust C 1 70.5 24.9 49.5 2 70.7 25 49.9 3 71 25.1 50.3
[0059] After determining the wetting angle of the coal dust sample corresponding to the plurality of sample parameters in the wetting test in step S202, the method further includes: determining the wetting angle of the coal dust sample corresponding to the plurality of sample parameters at different test times.
[0060] Step S203: Based on the above sample parameters and the corresponding wetting angle, determine the relationship between the wetting angle and the sample parameters to obtain the target relationship;
[0061] Specifically, the target relationship is obtained based on the sample parameters and the corresponding wetting angle. The target relationship can be a model.
[0062] To facilitate obtaining the target relationship, in one optional approach, the relationship between the wetting angle and the sample parameters is determined based on the sample parameters and the corresponding wetting angle, thereby obtaining the target relationship. This includes using one of the following methods: data analysis, statistical methods, machine learning, and artificial intelligence, to determine the relationship between the wetting angle and the sample parameters based on the sample parameters and the corresponding wetting angle, thereby obtaining the target relationship.
[0063] In one alternative approach, determining the relationship between the wetting angle and the sample parameters based on the aforementioned sample parameters and the corresponding wetting angle to obtain the target relationship includes: determining the target relationship as y = β0 + β1x1 + β2x2 + ... + β n x n Where y represents the aforementioned wetting angle, and x1, x2, ..., x... n These represent different data characteristics in the above sample parameters, β0, β1, β2, ..., β n Let β = (XTX)⁻¹XTY represent the coefficients of the linear regression model, where β represents the coefficient vector, X represents the matrix of the aforementioned data features, Y is the vector of the aforementioned wetting angles, T represents the transpose of the aforementioned matrix, and -1 represents the inverse of the aforementioned matrix. The target relationship obtained through the above model is more accurate.
[0064] In practical applications, Python modules can also be built for analysis and calculation. Specifically, first, the data is read; then, data preprocessing is performed; then, the wetting degree of coal dust is calculated; then, the wetting angle of each coal dust sample is obtained by calculating the difference between the initial and final contact angles; then, the average wetting degree of coal dust is calculated; then, the correlation between coal dust properties and wetting performance is calculated; finally, visualization analysis is performed, such as... Figure 3As shown, a correlation diagram of coal dust properties and wetting angle is presented, plotting the curve of coal dust wetting angle changing over time. Figures 4 to 6 As shown, a correlation diagram between coal dust properties and wetting angle is plotted, as follows. Figure 7 and Figure 8 As shown, a diagram illustrating the effect of surfactants on the wettability of coal dust is presented.
[0065] Step S204: Obtain the target physical parameters, and determine the target chemical parameters of the target coal dust sample based on the target physical parameters and the target relationship, so that the staff can process the target coal dust sample according to the target chemical parameters. The target physical parameters are the physical parameters of the target coal dust sample.
[0066] Specifically, based on the above-mentioned target relationships, the direction and methods for coal dust prevention and control can be determined, providing strong support for safe coal mine production.
[0067] The above embodiments obtain sample parameters from multiple coal dust samples, including physical and chemical parameters. Based on the sample parameters and their corresponding wetting angles, a target relationship is obtained. Thus, the target chemical parameters can be determined based on the target physical parameters and the target relationship. This allows for the rapid acquisition of target chemical parameters with a high degree of matching with the target coal dust, thereby improving the efficiency and effectiveness of coal dust control and solving the problem of low efficiency and poor effectiveness of coal dust prevention in the prior art.
[0068] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
[0069] This application also provides a coal dust control device.

This device is used to implement the above embodiments and preferred embodiments; details already described will not be repeated. As used below, the term "module" can refer to a combination of software and / or hardware that performs a predetermined function. Although the device described in the following embodiments is preferably implemented in software, hardware implementation, or a combination of software and hardware, is also possible and contemplated.
[0070] The following describes the coal dust control device provided in the embodiments of this application.

The physical parameters are used to characterize the physical properties of the coal dust samples, and the chemical parameters are used to characterize the parameters of the wetting agent and / or surfactant used in the wetting test of the coal dust samples.
[0073] Specifically, the above wetting test can be performed using experimental equipment such as a contact angle meter.

[0075] In one specific embodiment, the wetting angles of four samples under surfactants such as Tween 20 and Triton X-100 were measured, and the data obtained are shown in Table 6:

[0077] Coal dust sample number Tweening angle (°) Triton X-100 wetting angle (°) Sample 1 70 80 Sample 2 60 70 Sample 3 50 60 Sample 4 40 50
[0078] The aforementioned acquisition unit includes a first acquisition module, a second acquisition module, and a combination module. The first acquisition module acquires at least one of the following parameters of each coal dust sample: composition, surface functional groups, particle size distribution range, specific surface area, and porosity, to obtain the corresponding physical parameters. The second acquisition module acquires at least one of the following parameters: type of wetting agent, type of surfactant, and concentration of surfactant, to obtain the aforementioned chemical parameters.

[0084] Three different types of surfactants (surfactant A, surfactant B, and surfactant C) were selected to test the wetting properties of coal dust samples. The test data were statistically analyzed, and relevant information was collected.

This first determining module is used to perform the aforementioned wetting test on the coal dust samples corresponding to each of the aforementioned physical parameters under the conditions of the corresponding chemical parameters, thereby obtaining the corresponding wetting angle. In practical applications, the wettability of coal dust decreases with increasing time; therefore, it is necessary to select appropriate prevention and control methods for prompt treatment. The wettability of coal dust has a relatively small correlation with ash content, moisture content, and volatile matter content; therefore, different prevention and control measures can be adopted for different coal types.
[0092] In another specific embodiment, three coal dust samples with different particle sizes (coal dust A, coal dust B, and coal dust C) were selected and placed in a laboratory with 70% humidity.
