Description

Technical Field

[0001] The invention relates to the technical field of grouting treatment of mine water hazard, and in particular to a method and system for evaluating the effect of grouting treatment of mine water hazard. Background Art

[0002] As one of the main energy sources in my country, coal occupies a pivotal position in the national economy. However, in the process of coal mining, mine water hazards have always been a major hidden danger threatening the safe production of coal mines. With the continuous development of coal resources, the mining depth and difficulty have gradually increased, and the problem of mine water hazards has become increasingly complex and severe. The occurrence of mine water hazards will not only affect the normal production of coal, but may also cause serious casualties and property losses. In order to effectively prevent and control mine water hazards, grouting technology is widely used in mine water hazard management. Grouting technology injects slurry into the aquifer or water channel to change the physical and mechanical properties of the formation, so as to achieve the purpose of blocking the water source and strengthening the formation. However, the effect of grouting management is directly related to the safe production of the mine. Therefore, how to scientifically and accurately evaluate the effect of grouting management of mine water hazards has become an urgent problem to be solved.

[0003] A single evaluation method has certain limitations. For example, the analytic hierarchy process is highly subjective, the grey correlation analysis method has high requirements for data, and the fuzzy comprehensive evaluation method has a relatively complex calculation process. These limitations make it difficult for a single evaluation method to accurately and comprehensively evaluate the effect of grouting treatment of mine water hazards in practical applications. In the evaluation index system, the determination of index weights is a key issue. At present, the commonly used methods for determining index weights are subjective weighting method and objective weighting method. The subjective weighting method mainly relies on the experience and judgment of experts to determine the index weights, which is highly subjective and easily affected by the subjective factors of experts; the objective weighting method mainly determines the index weights based on the statistical characteristics of the data, which is highly objective, but may ignore the actual importance of the index.

[0004] Therefore, it is necessary to propose a new comprehensive evaluation method for the grouting treatment effect of mine water hazards to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a method and system for scientifically and accurately evaluating the effect of grouting treatment of mine water hazards, so as to solve the problems of the singleness of indicator weighting, the one-sidedness of single indicator evaluation and weak universality in the prior art, provide theoretical guidance for enhancing the stability of coal rock mass and reducing coal losses, and provide reliable technical support for the safe and efficient production of coal mines.

[0043] 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.

[0044] The purpose of the present invention is to provide a method and system for evaluating the effect of grouting treatment of mine water hazards, so as to solve the problems of the singleness of indicator weighting, the one-sidedness of single indicator evaluation and weak universality in the prior art, provide theoretical guidance for enhancing the stability of coal rock mass and reducing coal losses, and provide reliable technical support for the safe and efficient production of coal mines.

[0045] 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.

[0046] Figure 1 The flowchart of the mine water grouting treatment effect evaluation method provided by the present invention is as follows: Figure 2 The corresponding method framework diagram is shown in FIG.

[0047] The method for evaluating the effect of grouting treatment of mine water hazard provided by the present invention comprises:

[0048] S101: Obtain indicators for evaluating the effectiveness of grouting treatment of mine water hazards.

[0049] S102: Use the priority diagram-CRITIC combined weighting method to determine the weight values ​​of indicators for evaluating the effect of grouting treatment of mine water hazards.

[0050] S103: Based on the indicators and weight values ​​of the mine water grouting treatment effect evaluation, the grouting effect evaluation model is used to obtain the results of the mine water grouting treatment effect evaluation; wherein the grouting effect evaluation model is a model constructed by combining the double base point method and the rank sum ratio method.

[0051] For evaluation indicators, key parameters that can reflect the entire grouting process should be selected.

[0052] During the grouting process, the final grouting pressure is an important indicator for judging whether the grouting section has reached the grouting end standard, and it can determine the filling rate and quality of the grouting. In the grouting project, the slurry fills and squeezes the cracks under the action of the grouting pressure, and the final grouting pressure is the key parameter for the compaction effect, which has a controlling effect on the stability and stability duration of the rock mass after grouting transformation. Therefore, a reasonable final grouting pressure can ensure high-quality grouting effects and reduce the amount of grouting. Excessive grouting pressure may further open, expand, and penetrate the internal cracks of the rock mass, causing instability and damage to the rock mass.

[0053] Practice has shown that in grouting renovation projects, the amount of grouting has a certain indicative effect on the grouting effect, but the relationship between the grouting amount and the grouting effect is still unclear. The grouting amount is largely affected by the geological structure of the grouting location. Therefore, it is difficult to quantitatively evaluate the grouting effect by the amount of grouting. Combined with the experience of coal mine water prevention and control, the amount of dry material per unit length is used as an important evaluation indicator. Generally speaking, when the water inflow is the same, the larger the amount of dry material per unit length, the better the expected water blocking effect.

[0054] The purpose of grouting to transform aquifers is to prevent water inrush from mines. The permeability of rock and soil is an important reference for judging whether it can cause water inrush, and the main indicator reflecting the permeability of rock and soil is water permeability. Water permeability is a physical quantity that characterizes the degree of water permeability of an object under normal atmospheric pressure. The smaller the water permeability of the rock after grouting, the weaker its water permeability and the stronger its water-blocking ability.

[0055] During the grouting process, the consumption of drilling fluid can also quantitatively evaluate the effect of grouting to a certain extent. It can reveal the stratum structure of the coal seam floor within the influence range of the hole. The boreholes with high drilling fluid consumption have more complex geological structures and more developed faults or dense karst fissures; the boreholes with less consumption have simpler geological structures. The complexity of the stratum structure will affect the subsequent grouting project. The more complex the stratum, the higher the requirements for the grouting process and the greater the construction difficulty, which will have a certain impact on the grouting effect.

[0056] Therefore, the present invention selects four variables as indicators for evaluating the grouting effect, namely, drilling fluid consumption, grouting final pressure, water permeability, and dry material per unit length. Grouting final pressure and dry material per unit length can be directly obtained at the grouting station; drilling fluid consumption can be measured during drilling; water permeability can be obtained through on-site water pressure test. The four indicators are independent of each other and meet the principles of objectivity, comprehensiveness, and easy collection of indicator selection.

[0057] In view of the limitations of a single evaluation method, the present invention comprehensively considers subjective and objective factors, combines subjective weighting method with objective weighting method, and comprehensively considers expert experience and information of the data itself, so as to make the determination of weights more scientific and reasonable.

[0058] Specifically, the subjective weighting method uses the priority diagram method, and the objective weighting method uses the CRITIC method.

[0059] The present invention uses the priority diagram method and the CRITIC method to calculate the weights of the indicators for evaluating the effect of grouting treatment of mine water hazards, respectively, to obtain the subjective weight α and the objective weight β, and to obtain the weight values ​​of the indicators for evaluating the effect of grouting treatment of mine water hazards by combining the subjective weight and the objective weight. Since the weight allocation principles of the priority diagram method and the CRITIC method are different, and the data features used are also different, the former is based on data size information, and the latter is based on data volatility and the correlation between data, the corresponding indicator weight values ​​of the two methods are multiplied and then divided by the sum of the products of all indicator weights as the comprehensive weight:

[0060] Right now

[0061] The present invention combines the double base point method (TOPSIS) with the rank sum ratio method (RSR) to construct a grouting effect evaluation model.

[0062] The TOPSIS method seeks the best and worst solutions in each indicator, constructs a two-dimensional data space of the distance between the evaluation indicator and the best and worst solutions, and compares each evaluation indicator with the best and worst solutions on this basis. It has the advantages of small data loss in the calculation process and intuitive geometric meaning. The core of the TOPSIS method is to calculate the gap between each evaluation indicator and the best and worst vectors and the degree of proximity between the evaluation target and the optimal solution. The greater the degree of proximity Ci, the better the solution. The evaluation targets are sorted according to the relative proximity obtained by the TOPSIS method to obtain the rank. The rank sum ratio method is used to divide the n evaluation targets into m evaluation levels, construct an evaluation matrix, and calculate the RSR value; the weight value and rank sum ratio of the indicators for evaluating the effect of grouting treatment of mine water hazard are combined to obtain the comprehensive evaluation value WRSR and sort them accordingly, and the sorting result is used as the result of the evaluation of the effect of grouting treatment of mine water hazard.

[0063] Among them, R ij is the rank of the element in the i-th row and j-th column of the matrix.

[0064] The cumulative ranking frequency is converted into Probit and used as the independent variable, and WRSR as the dependent variable to obtain a regression equation, namely WRSR = a + b × Probit

[0065] According to the WRSR value calculated by the regression equation, the evaluation targets are sorted and classified, aiming to determine the fitting curve of the model and verify the rationality of the model. The evaluation targets are sorted and classified according to the WRSR obtained by the regression formula.

[0066] In a specific embodiment, the mine water hazard grouting treatment effect evaluation method of the present invention further includes: converting the evaluation result into a visual partition diagram, and comparing and verifying the water inflow result revealed by the underground water exploration and drainage drilling after grouting. The visual partition diagram uses the interpolation method to analyze the RSR classification results, and the water inflow data is taken from the actual data of the on-site water exploration and drainage drilling after the grouting is stabilized.

[0067] The present invention also provides a system for running a method for evaluating the effect of grouting treatment of water hazards in mines, such as Figure 3 As shown, the system specifically includes: an indicator acquisition unit 201, a weight value determination unit 202 and an evaluation unit 203.

[0068] The index acquisition unit 201 is used to acquire the index for evaluating the effect of grouting treatment of mine water hazard. The index for evaluating the effect of grouting treatment of mine water hazard includes: drilling fluid consumption, grouting final pressure, water permeability and dry material per unit length.

[0069] The weight value determination unit 202 is used to determine the weight values ​​of the indicators for evaluating the effect of grouting treatment of mine water hazards by adopting the priority diagram-CRITIC combined weighting method.

[0070] The evaluation unit 203 is used to obtain the results of the mine water grouting treatment effect evaluation based on the indicators and weight values ​​of the mine water grouting treatment effect evaluation model; wherein the grouting effect evaluation model is a model constructed by combining the double base point method and the rank sum ratio method.

[0071] The weight value determination unit 202 specifically includes: a weight calculation module and a weight value determination module.

[0072] The weight calculation module is used to calculate the weights of indicators for evaluating the effect of grouting treatment of mine water hazards using the priority diagram method and the CRITIC method, respectively, to obtain subjective weights and objective weights.

[0073] The weight value determination module is used to determine the weight values ​​of indicators for evaluating the effect of grouting treatment of mine water hazards by comprehensively considering subjective weights and objective weights.

[0074] The evaluation unit 203 specifically includes: a sorting module, a rank sum ratio calculation module and an evaluation module.

[0075] The sorting module is used to sort the evaluation targets based on the indicators of the evaluation of the effect of grouting treatment of mine water hazards, and to obtain the rank by using the relative proximity obtained by the double base point method;

[0076] The rank sum ratio calculation module is used to divide the levels of the evaluation targets into levels based on the obtained ranks using the rank sum ratio method to construct an evaluation matrix and calculate the corresponding rank sum ratio;

[0077] The evaluation module is used to obtain a comprehensive evaluation value by combining the weight values ​​and rank sum ratios of indicators for evaluating the effect of grouting for comprehensive mine water hazard treatment and sorting them accordingly, and the sorting result is used as the result of the evaluation of the effect of grouting for mine water hazard treatment.

[0078] In a specific implementation, the present invention selects four indicators: drilling fluid consumption, grouting final pressure, dry material amount per unit length and permeability, with a total of 52 grouting holes. The boreholes are represented by main hole-branch hole-grouting section, such as D1-1-1. The sample quantity information descriptive statistics are shown in Table 1.

[0081]

[0082]

[0083]

[0084] According to the effect of the indicators on the evaluation results, the four evaluation indicators are divided into positive indicators and negative indicators. According to the weights of each indicator obtained in the table, the optimal and worst matrix vectors are found according to the TOPSIS method steps and the relative proximity C value of each borehole is calculated. See the attached Figure 4 .

[0085] According to the principle of rank sum ratio method, the value and ranking of weighted rank sum ratio are calculated, the distribution table is listed to get the probability unit, and the regression equation is calculated: WRSR = -0.104 + 0.122 × Probit

[0086] According to the fitting order of WRSR values ​​and the commonly used numerical classification method in the corresponding reasonable classification method, the Delphi method is used to divide the grouting effect into two levels, namely, relatively weak area, qualified area and excellent area, as shown in Table 2. The RSR method fitting curve is shown in the attached figure. Figure 5 As shown in the figure, the original data and model prediction values ​​of the model are displayed. From the analysis of the RSR evaluation results, the model's goodness of fit is 0.938, which performs relatively well. Considering that the differences in workers' construction standards, drilling and grouting technology, and geological conditions within the drilling range will affect the fitting standard deviation, the basic needs of model evaluation are met.

[0088] Grade Percentile critical value Probit critical value RSR critical value (fitted value) Relatively weak area-1 <15.866 <4 <0.382 Qualifying Zone-2 15.866～84.134 4～6 0.382～ Excellent Zone-3 ≥84.134 ≥6 0.625～

[0089] As attached Figure 6 and Figure 7The evaluation results were converted into a visual zoning map and compared with the water inflow results revealed by the underground water exploration and drainage drilling after grouting. The areas with large water inflow are concentrated in the middle and west of the 110504 working face, with the maximum water inflow of 70m 3 / h, which is a relatively weak area. The water gushing area revealed by the downhole drilling project is basically consistent with the evaluation model zoning, indicating that the proposed comprehensive evaluation system for grouting effect is used to evaluate the ground grouting renovation project, which is consistent with the actual verification effect of on-site downhole drilling. This proves that the method has certain rationality and scientificity, and can provide a reference for the evaluation of grouting effect in ground areas with similar conditions.
