[0002] With the increase in the depth of coal mining and the difficulty of tunnel excavation, traditional support technology is gradually unable to meet actual needs, especially in environments with complex geological conditions and unstable coal and rock masses. As a new type of support material, spraying materials have gradually replaced traditional support methods such as anchor support and shotcrete because of their advantages such as good adhesion, tensile resistance, crack resistance and high construction efficiency. They are used in coal mine tunnel support, especially for coal and rock masses with high cracks and irregular shapes. Although traditional metal mesh support and shotcrete have strong rigidity and bearing capacity, they have poor adhesion and difficulty in construction when dealing with irregular coal and rock surfaces. In contrast, spraying materials can quickly solidify and form a strong bond with the surface of coal and rock masses to form a stable composite support structure, which enhances the overall stability of the tunnel.

[0021] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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.

[0022] Combine the following Figure 1-Figure 2 The invention describes a method, system and electronic equipment for evaluating the comprehensive performance of tunnel spraying materials.

[0023] like Figure 1 As shown, an embodiment of the present invention provides a method for evaluating the comprehensive performance of tunnel spraying materials, which is applied to underground coal mine tunnels and includes the following steps: Step 1: Determine the type of spray material.

[0024] Step 2: Establish a comprehensive performance evaluation model for the spraying material.

[0025] Step 3: Conducting various performance tests on the spraying material to obtain actual performance data of various performances.

[0026] Step 4: According to the comprehensive performance evaluation model, the actual performance data of each performance is processed and analyzed to identify the bottleneck of material performance.

[0027] Step 5: Optimize the formulation and construction process of spraying materials.

[0028] Through the above scheme, it can be known that the comprehensive performance evaluation method of tunnel spraying materials provided by the present invention can comprehensively examine the various characteristics of spraying materials in the complex environment of coal mines by establishing a comprehensive performance evaluation model, ensure that the evaluation results are more comprehensive and accurate, and set reasonable evaluation standards according to the specific working environment, so as to better reflect the performance of materials in practical applications; through a comprehensive performance evaluation of spraying materials, potential risk points can be identified in advance to avoid problems such as material failure in actual construction. At the same time, the optimized materials can reduce the construction difficulty and maintenance costs and improve economic benefits while ensuring the support effect.

[0029] It can ensure that the spraying material has good adhesion, uniformity and stability in the underground environment of coal mines, thereby enhancing the overall stability of the tunnel and improving the safety and efficiency of coal mining. In addition, the optimized spraying material can also shorten the construction period and reduce the labor intensity of workers.

[0030] In this embodiment, step 2 specifically includes the following steps: Step 21: Determine the evaluation indicators. The evaluation indicators covered by the comprehensive performance evaluation model include: mechanical properties, fire resistance, wear resistance, impact resistance, penetration resistance and freeze-thaw resistance. Among them, mechanical properties such as tensile strength, compressive strength, shear strength, etc. are important parameters for evaluating the structural stability and bearing capacity of spray materials. Fire resistance is used to test the stability of spray materials in high temperature environments to ensure that they can provide necessary protection when a fire occurs. Wear resistance is used to evaluate the material's ability to resist wear, which is crucial for spray materials that are in friction and impact environments for a long time. Impact resistance is used to measure the material's ability to withstand sudden forces such as falling rocks or tool collisions. Penetration resistance prevents moisture, gas or other harmful substances from penetrating the material to protect the internal structure from erosion. Freeze-thaw resistance ensures that the material can maintain its physical and chemical properties after repeated freezing and thawing cycles.

[0031] Step 22: Set specific evaluation criteria or thresholds for each performance indicator based on the different working environments of coal mine tunnels. It is understandable that different coal mine tunnels have unique geological conditions and working environments, so the evaluation criteria for spray materials need to be set according to specific environmental characteristics. For example, in high humidity areas, permeability resistance and corrosion resistance may be the most important considerations; while in areas prone to fire, more attention is paid to fire resistance. The setting of evaluation criteria should be based on a detailed investigation and analysis of the on-site environment, and refer to relevant industry specifications and standards.

[0032] Furthermore, step 2 also includes: Step 23: Use the analytic hierarchy process and fuzzy comprehensive evaluation method to determine the importance weight of each performance index; construct a weighted comprehensive scoring model, weight each performance index according to its importance, and calculate the comprehensive performance score of the spraying material. Among them, the analytic hierarchy process is a multi-criteria decision-making method for determining the relative importance of each performance index. By constructing a judgment matrix, the importance of different performance indicators is compared two by two, and appropriate calculation methods such as row element product and square root method are used to calculate the weight of each index. This method not only considers quantitative data, but also incorporates qualitative judgment, making the evaluation results closer to the actual situation; for performance indicators that are difficult to measure with precise numerical values, such as fire resistance and anti-permeability, the model adopts the fuzzy comprehensive evaluation method. By defining the membership function, the test results are converted into fuzzy numbers, and the weights determined by the analytic hierarchy process (AHP) are combined to calculate the comprehensive performance score. This method not only considers quantitative data, but also incorporates qualitative judgment, making the evaluation results more scientific and reasonable.

[0033] With this setting, by constructing a weighted comprehensive scoring model, each performance indicator can be weighted and scored according to its importance, and finally a comprehensive performance score can be obtained. This not only helps to compare the advantages and disadvantages of different spraying materials, but also provides a scientific basis for material optimization and selection. For example, the chemical composition of the material can be adjusted or the spraying process can be improved according to the evaluation results to improve its specific performance.

[0034] In some embodiments, when evaluating a new type of spray material, the following performance indicators and their weights are determined through a comprehensive performance evaluation model: tensile strength: weight 0.2; compressive strength: weight 0.2; Fire resistance: weight 0.15; wear resistance: weight 0.15; anti-penetration: weight 0.15; freeze-thaw resistance: weight 0.1. Construction performance: weight 0.05.

[0035] Afterwards, through standardized laboratory tests, the following performance data were obtained: tensile strength: 30 MPa; compressive strength: 50 MPa; fire resistance: stable at 800°C for 2 hours; Wear resistance: wear volume is 0.5 mm³ / 1000 revolutions; water permeability resistance: water permeability coefficient is cm / s; Freeze-thaw resistance: no obvious damage after 100 freeze-thaw cycles; Construction performance: good adhesion and good uniformity.

[0036] Through the fuzzy comprehensive evaluation method, we convert these performance data into membership values, multiply them by the corresponding weights, and finally calculate the comprehensive performance score; assuming the calculation results are as follows: tensile strength: membership 0.8, weighted score 0.16; compressive strength: membership 0.9, weighted score 0.18; fire resistance: membership 0.7, weighted score 0.105; wear resistance: membership 0.6, weighted score 0.09; anti-permeability: membership 0.7, weighted score 0.105; freeze-thaw resistance: membership 0.8, weighted score 0.08; construction performance: membership 0.9, weighted score 0.045; then the comprehensive performance score = 0.16 + 0.18 + 0.105 + 0.09 + 0.105 + 0.08 + 0.045 = 0.765; Through this process, it can be concluded that the comprehensive performance score of the spray material is 0.765 (full score 1.0), indicating that its overall performance is relatively excellent. However, the test results also show some potential room for improvement, such as the fire resistance and anti-permeability are slightly insufficient, and these properties can be further optimized by adjusting the material formula or adding functional additives.

[0037] In this embodiment, the test data in step 3 are obtained through a series of scientific experiments and test methods, which include but are not limited to adhesion test, corrosion resistance test, wear resistance test, temperature resistance test, etc. In addition, it also includes environmental adaptability test, and accelerated aging test is carried out in simulated underground high temperature, high humidity, dust and other environments to evaluate the stability of the spraying material in extreme environments.

[0038] In this embodiment, step 4 includes: according to the weighted comprehensive scoring model, converting the actual performance data of each indicator into a score, and performing weighted summation to obtain a comprehensive performance score of the spraying material; Based on the comprehensive performance score and the scores of each indicator, the bottlenecks and weak links of the spray material performance are identified. With this setting, by processing and statistically analyzing the test data, it is possible to identify which performance indicators are the key factors affecting the overall performance. For example, if a material exhibits poor fire resistance in a high temperature environment, or is prone to corrosion in high humidity conditions, these may be performance bottlenecks.

[0039] For example, when evaluating a new spray material, experimental testing revealed: Mechanical properties: tensile strength is 30 MPa, compressive strength is 50 MPa, shear strength is 20 MPa; Fire resistance: stable at 800°C for 2 hours; Anti-permeability: Water permeability coefficient is cm / s; Freeze-thaw resistance: There is no obvious damage after 100 freeze-thaw cycles. Through the analysis of laboratory performance test data, the fire resistance bottleneck was found. In high temperature environments above 900°C, the fire resistance of the material decreased significantly, manifested as surface cracking and peeling, so more fire-resistant additives need to be added to improve the stability of the material under extreme high temperature conditions. Although the material has good permeability resistance, slight moisture penetration may still occur after long-term use in high humidity environments. For this reason, a waterproof coating can be introduced or a hydrophobic additive can be added to further improve the permeability resistance. These optimization schemes are incorporated into the comprehensive performance evaluation model, the weighted scores of each performance indicator are recalculated, and a new round of test verification is carried out. Through this feedback mechanism, a virtuous interactive cycle is formed between the model and the test data, which jointly promotes the continuous advancement of spray material technology.

[0040] Furthermore, step 4 also includes: using finite element analysis method to model and simulate the stress conditions and deformation performance of the spray material in the actual working environment; analyzing the impact of different environmental factors on the performance of the spray material, and predicting the performance change trend in long-term use.

[0041] With this setup, a continuous improvement feedback loop is formed between the comprehensive performance evaluation model and the data obtained from the test. On the one hand, the model provides guidance for the test design; on the other hand, the test results in turn verify and optimize the model. The results of the data analysis and optimization steps can be directly fed back to the comprehensive performance evaluation model to update and optimize the model parameters. For example, if the test data shows that the importance of a certain performance indicator is higher than expected, the weight of the indicator can be appropriately increased in the model; if new performance bottlenecks are found, new evaluation criteria can be introduced or existing criteria can be adjusted; Through data analysis and optimization, the accuracy and applicability of the comprehensive performance evaluation model can be verified. If there is a large deviation between the test results and the model prediction values, the model parameters can be adjusted in time to improve its accuracy. In addition, new test data can also be used to further improve the membership function and fuzzy comprehensive evaluation method to make the model closer to the actual situation. Through continuous iteration and improvement, the accuracy and applicability of the evaluation system can be gradually improved.

[0042] For example, in the process of evaluating a new type of spray material, first, based on the comprehensive performance evaluation model, determine the performance indicators that need to be tested, including tensile strength, fire resistance, etc.; then, set evaluation standards, such as the tensile strength should reach xMPa, and the fire resistance should remain stable at high temperature for at least y hours; after that, conduct standardized laboratory tests to obtain the specific values ​​of each performance indicator, and by comparing the test results with the model prediction values, if it is found that the actual performance of the fire resistance indicator is lower than expected, it is necessary to adjust the proportion of refractory additives, so as to optimize the model according to the test data to make it more in line with the actual situation, and through statistical analysis, re-evaluate the importance weight of each performance indicator, and appropriately increase the weight of the fire resistance indicator.

[0043] The fuzzy comprehensive evaluation method is used to convert the test results into fuzzy numbers, and the comprehensive performance score is calculated by combining the weights determined by the hierarchical analysis method. The stress and deformation performance of the material under actual use conditions are simulated through finite element analysis to predict its long-term stability. According to the test results and model analysis, optimization plans are proposed, such as adjusting the material composition, improving the spraying process, etc. The optimized materials are applied in the field pilot, and feedback information from actual use is collected to further improve the model and optimization plan. Through the above process, a benign interactive relationship is formed between the comprehensive performance evaluation model and the various performance data obtained from the test, which jointly promotes the continuous improvement and development of the spray material evaluation system.

[0044] Step 5 includes: adjusting the chemical composition of the spray material, adding additives and improving spray process parameters, wherein the process parameters include spray thickness and spray pressure. The additives may be antifreeze and anti-aging additives to improve the durability and adaptability of the spray material.

[0045] The embodiment of the present invention also provides a comprehensive performance evaluation system for tunnel spraying materials, including: A target setting module to determine the type of spray material; Establishing a module for establishing a comprehensive performance evaluation model of the spraying material; A testing module, used to test various properties of the spraying material and obtain actual performance data of various properties; A data processing module, for processing and analyzing the actual performance data of various performances according to the comprehensive performance evaluation model, and identifying the bottleneck of material performance; Process optimization module, used to optimize the formulation and construction process of spraying materials.
