[0048] [Rule 26 Correction 19.12.2025] Currently, the indicators used for water source discrimination are mainly inorganic indicators such as major anions and cations in water and total dissolved solids (TDS). However, in practice, total organic carbon (TOC), ultraviolet absorbance (UV 254) and Dissolved Organic Matter (DOM) also exist great differences. At present, the methods of using hydrochemistry to distinguish water sources mainly focus on three categories: multivariate statistical method, nonlinear analysis method and machine learning. Compared with traditional methods, machine learning algorithms have more advantages in processing nonlinear and high-dimensional data, and have strong adaptability. Among commonly used machine algorithms, Support Vector Machine (SVM), Extreme Learning Machine (ELM), Random Forest (RF) and Back Propagation Neural Network (BP neural network) have been applied in mine water source discrimination; for water sources with similar composition, it is difficult to make accurate judgment only by inorganic water chemical indicators.
[0049] [According to Rule 26, correct 19.12.2025] The present application provides a kind of mine gushing water source intelligent discrimination method, device, equipment and storage medium, the method comprises: obtaining the water chemical index of sample to be discriminated water source;Wherein, water chemical index includes multiple inorganic indicators and multiple organic indicators;Water chemical index is input into preset water source discrimination model, obtains the water source type of sample to be discriminated water source.Such, on the basis of inorganic index discrimination, join organic index, solve the problem that inorganic water chemical index is difficult to accurately discriminate similar water sample, improve the accuracy of water source category judgment.
[0050] [According to Rule 26, correct 19.12.2025] The specific embodiments of the present application are given below, it should be noted that the present application is not limited to the following specific embodiments, any equivalent transformation made on the basis of the technical scheme of the present application falls within the protection scope of the present application.
[0051] [According to Rule 26, correct 19.12.2025] Embodiment:
[0052] [According to Rule 26, correct 19.12.2025] The present embodiment provides a kind of mine gushing water source intelligent discrimination method, Fig. 1 is the flowchart of mine gushing water source intelligent discrimination method of the present application, see Fig. 1, the method comprises the following steps:
[0053] [According to Rule 26, correct 19.12.2025] S1, obtaining the water chemical index of sample to be discriminated water source;Wherein, water chemical index includes multiple inorganic indicators and organic indicators;
[0054] [According to Rule 26, correct 19.12.2025] Inorganic indicators include main anion and cation in water and TDS value etc.Main ions in water include K + , Na+ Ca 2+ Mg 2+ Cl - SO4 2- HCO3 - and so on. GB / T 14848—2017 Groundwater Quality Standard can be referred to for testing the inorganic ions and TDS in the water sample. K + Na + are all common inorganic ions in water, but the content of K + is usually low. Therefore, K + Na + can be considered as a whole, represented in the form of K + + Na + .
[0055] [Corrected according to Rule 26 19.12.2025] Organic indicators include total organic carbon, ultraviolet absorbance, and dissolved organic matter in the water layer. The differences between different organic components in dissolved organic matter can be intuitively reflected by fluorescence spectrum. The multi N / C 2100 expert total organic carbon / total nitrogen analyzer can be used to detect TOC; the Evolution 60 ultraviolet-visible spectrophotometer can be used to detect UV 254 ; and the fluorescence spectrophotometer (HITACHI F-7000) can be used to extract DOM fluorescence data. In order to quantitatively analyze the differences of DOM in different water samples, the DOM fluorescence data of each water source sample is quantified by mathematical method. Specifically, the main components of fluorescence spectrum can be extracted and quantified by parallel factor method (Parallel Factors Analysis, PARAFAC). Specifically, first, arrange the three-dimensional fluorescence data of all water samples DOM, then use the fluorescence microscopy digital object identifier (Digital Object Identifier for Fluorescence Microscopy, DOMFluor) toolbox provided by matrix laboratory (Matrix Laboratory, MATLAB) to analyze and process the three-dimensional fluorescence data. The specific processing steps include:
[0056] [Corrected according to Rule 26 19.12.2025] (a1) Load data and draw excitation-emission matrix (Excitation-Emission Matrixs, EEMs);
[0057] [Corrected according to Rule 26 19.12.2025] (a2) Cut the spectral region affected by scattering peak;

[0059] [Rule 26 correction 19.12.2025] (a4) Split-half test on the selected component number model;
[0060] [Rule 26 correction 19.12.2025] (a5) Derive experimental data, including: the fluorescence spectrum of each component, the fluorescence intensity of each component in each sample and its corresponding emission load and excitation load.
[0061] [Rule 26 correction 19.12.2025] FIGS. 2-4 are schematic diagrams of the fluorescence spectrum and load of the organic components in the embodiment, wherein FIGS. 2-4 are the fluorescence spectrum and load of three organic components, respectively. Referring to FIG. 2, Component 1 has two excitation peaks (250 nm / 330 nm) and one emission peak (405 nm), which indicates that Component 1 contains hydrophobic organic acid and humic acid-like and the latter is more. Referring to FIG. 3, Component 2 has three excitation peaks (230 nm / 250 nm / 280 nm) and one emission peak (308 nm), which indicates that Component 2 contains tryptophan-like and tryptophan-containing protein-like. Referring to FIG. 4, Component 3 has two excitation peaks (225 nm / 280 nm / 305 nm) and one emission peak (340 nm), which indicates that Component 3 contains tyrosine and tryptophan-containing protein-like and the former is more.
[0062] [Rule 26 correction 19.12.2025] S2, input the water chemical index into the preset water source discrimination model to obtain the water source type of the water source sample to be discriminated.
[0063] [Rule 26 correction 19.12.2025] The water source type includes Quaternary water, Cretaceous water, Zhuluo Formation water or Yan'an Formation water and the like aquifer water sample.
[0064] [Rule 26 correction 19.12.2025] The water source type of the water source is discriminated to realize the prevention of mine water disaster, therefore, in the embodiment, before the water source type is discriminated, the geological and hydrogeological conditions of the area to be studied can be studied to determine the target aquifer to be studied. That is, the water chemical index of the water source sample to be discriminated can be obtained from the target aquifer.
[0065] [According to the rules 26 correction 19.12.2025] Figure 5 is a flowchart of obtaining a water source discrimination model in an embodiment of the present application, referring to Figure 5, the process of obtaining a water source discrimination model includes the following steps:
[0066] [According to the rules 26 correction 19.12.2025] S21, according to the water chemical indicators of a plurality of water source samples, a data set of water chemical indicators of a plurality of water source samples is constructed;
[0067] [According to the rules 26 correction 19.12.2025] The water chemical indicators include a plurality of inorganic indicators and organic indicators as described above, so that for each sample water source, a set of data containing inorganic indicators and organic indicators as described above can be obtained. By obtaining the water chemical indicators of a plurality of sample water sources, a data set of water chemical indicators of a plurality of sample water sources can be constructed. For example, the inorganic indicators include K + +Na + , Ca 2+ , Mg 2+ , Cl - , SO4 2- , HCO3 - and TDS. The organic indicators include total organic carbon, ultraviolet absorbance and dissolved organic matter, and the dissolved organic matter can obtain specific organic components and contents by analyzing the fluorescence spectrum, for example, the organic components in the embodiment include three components as shown in Figures 2 to 4. Thus, the data set of water chemical indicators of each sample water source can be obtained, and a data set of water chemical indicators of a plurality of sample water sources can be constructed.
[0068] [According to the rules 26 correction 19.12.2025] The number of water source samples is n, and each water source sample includes p water chemical indicators, which are represented by x1, x2, …, x p ; the data set of n water source samples is represented by the following formula (1):
[0069] [According to the rules 26 correction 19.12.2025] Wherein X is the data set, x is one of the water chemical indicators, n is the number of water source samples, and p is the number of water chemical indicators.
[0070] [According to the rules 26 correction 19.12.2025] S22, the data set is reduced by a predetermined data method, and a reduced data set is obtained;
[0071] [Corrected according to Rule 26 19.12.2025] The discrimination of mine water sources is affected by the correlation between various water chemical indicators, such as the above-mentioned inorganic ions and organic ions, and there is a certain correlation between the water chemical indicators, which greatly increases the complexity of the analysis, so it is necessary to reduce the dimensionality of the original data set and process the high-dimensional, correlated variables into new synthetic variables that are low-dimensional, mutually independent, and can represent most of the information of the original variables. The correlation between each water chemical indicator is determined to reduce unnecessary calculations. The correlation between each water chemical indicator is determined by the Pearson correlation coefficient (Pearson), which is represented by formula (2):
[0072] [Corrected according to Rule 26 19.12.2025] Wherein, r xy is the Pearson correlation coefficient of index x and index y, n is the number of samples, x i is the i-th actual value of index x, y i is the i-th actual value of index y.
[0073] [Corrected according to Rule 26 19.12.2025] Table 1 is a correlation coefficient matrix composed of the correlation coefficients between each water chemical indicator in the actual measured sample water source.
[0074] [Corrected according to Rule 26 19.12.2025] Table 1 is a correlation coefficient matrix composed of the correlation coefficients between each water chemical indicator in the actual measured sample water source
[0075] [Corrected according to Rule 26 19.12.2025] Wherein, the water chemical indicators include inorganic indicators K + +Na + , Ca 2+ , Cl - , SO4 2- and other inorganic ions, and TDS, and organic indicators include UV 254 , TOC and component 2 as shown in Figure 2.
[0076] [Corrected according to Rule 26 19.12.2025] As can be seen from Table 1, there is a clear correlation between each indicator, among which the correlation of SO4 2- with K + +Na + , Ca 2+ , TDS reaches 0.916, 0.949 and 0.982 respectively; the correlation coefficients of K + +Na + with Ca 2+ , TDS reach 0.825 and 0.969 respectively; the correlation coefficient of Ca 2+The correlation coefficients with TDS reached 0.908 respectively. C2 showed a significant negative correlation with K + +Na + , Ca 2+ , SO4 2- and TDS, which indicated that there was information redundancy in the data set. If the eight indicators were directly used to identify the water source type, the complexity and calculation amount of the model would be increased, which would affect the discrimination efficiency and accuracy. Therefore, the data set needs to be reduced.
[0077] [According to Rule 26 Correction 19.12.2025]In the embodiments of the present application, the dimensionality reduction of the data set of the water chemical indicators of the above-mentioned multiple sample water sources is realized by principal component analysis (PCA).
[0078] [According to Rule 26 Correction 19.12.2025]The PCA is a classical statistical method, which extracts new variables reflecting the nature of things by linear transformation of the attribute characteristics of the original variables, removes redundancy and reduces noise, and achieves the purpose of dimensionality reduction.
[0079] [According to Rule 26 Correction 19.12.2025]The above step S22 includes the following steps:
[0080] [According to Rule 26 Correction 19.12.2025]S221, the data set is processed by zero-mean normalization to obtain a standardized data matrix;
[0081] [According to Rule 26 Correction 19.12.2025]S222, the principal component extraction is performed on the standardized data matrix to obtain a principal component score matrix;
[0082] [According to Rule 26 Correction 19.12.2025]S223, the dimensionality reduction of the standardized data matrix is performed by the principal component score matrix to obtain a reduced data set.
[0083] [According to Rule 26 Correction 19.12.2025]The zero-mean normalization processing of the data set can make the mean value of the transformed attribute of each data in the data set zero. It can be obtained by subtracting the mean value of each attribute in the data set from the value of the attribute.
[0084] [According to Rule 26 Correction 19.12.2025]The zero-mean normalization processing of the data set can be realized by the following formula (3):
[0085] [According to Rule 26 Correction 19.12.2025]Wherein, μ A is the mean value of a water chemical indicator A, and σA is a standard deviation of a water chemistry index A, and v is a normalized value of a certain value x of a water chemistry index A.
[0086] [Corrected according to Rule 26 19.12.2025] After the data set is zero-mean normalized by the above formula (3), a standardized data matrix can be obtained, and then a principal component score matrix is obtained by performing principal component extraction on the standardized data matrix.
[0087] [Corrected according to Rule 26 19.12.2025] Specifically, the above step S222 includes the following steps:
[0088] [Corrected according to Rule 26 19.12.2025] Step b1, determining the covariance matrix of the standardized data matrix;
[0089] [Corrected according to Rule 26 19.12.2025] Step b2, determining the eigenvalues of the covariance matrix and the eigenvectors corresponding to the eigenvalues;
[0090] [Corrected according to Rule 26 19.12.2025] Step b3, selecting N eigenvalues that meet the preset condition according to the size of the eigenvalues, to obtain an eigenvalue set;
[0091] [Corrected according to Rule 26 19.12.2025] Step b4, constructing a principal component score matrix according to the eigenvectors corresponding to each eigenvalue in the eigenvalue set.
[0092] [Corrected according to Rule 26 19.12.2025] When the water chemistry index of each sample water source contains p indexes, the covariance matrix can be solved to obtain p eigenvalues. The corresponding feature information contained in the data is gradually decreasing, that is, the contribution rate of each eigenvalue is gradually decreasing. Therefore, in the calculation process, in order to reduce redundant calculation, only the eigenvectors corresponding to part of the eigenvalues can be used as the composition of the principal components, so as to construct the principal component score matrix.
[0093] [Corrected according to Rule 26 19.12.2025] Wherein, the contribution rate of the eigenvalue is the proportion of the eigenvalue in all eigenvalues of the covariance matrix, that is, the proportion of the variance corresponding to the eigenvalue in the sum of all variances in the principal component. The greater the contribution rate of the eigenvalue, the more information the original water chemistry index contains in the corresponding principal component, and therefore the value of N can be determined by the contribution rate of the eigenvalue corresponding to the covariance matrix.
[0094] [According to Rule 26, the correction is made on 19.12.2025] The preset condition can be that the feature value is greater than a first preset threshold. Wherein, the value of the first preset threshold can be a pre-set fixed threshold, or can also be specifically determined based on the application demand in the actual calculation process.
[0095] [According to Rule 26, the correction is made on 19.12.2025] When the feature value is less than a certain threshold, the proportion of its corresponding contribution rate is small, that is, it contains less information. Therefore, this part of the feature value can not be considered. By selecting the feature value greater than the first preset threshold to exclude the part of the feature value containing less information, a large amount of redundant calculation can be reduced, and the calculation efficiency can be improved.
[0096] [According to Rule 26, the correction is made on 19.12.2025] According to the size of the feature value, N feature values satisfying the preset condition are selected to obtain the feature value set, which can be respectively compared each feature value with the first preset threshold, and the feature value greater than the first preset threshold is selected to construct the feature value set.
[0097] [According to Rule 26, the correction is made on 19.12.2025] In other embodiments, the preset condition can be that the cumulative contribution rate of each feature value is greater than a second preset threshold.
[0098] [According to Rule 26, the correction is made on 19.12.2025] Similarly, the value of the second preset threshold can also be a pre-set fixed threshold, or can also be specifically determined based on the application demand in the actual calculation process.
[0099] [According to Rule 26, the correction is made on 19.12.2025] In some embodiments, taking 85% as an example of the second threshold, according to the size of the feature value, the feature values are sorted from large to small, and the feature values whose cumulative contribution rate exceeds 85% can actually represent most of the information. Therefore, the value of N can be the first N feature values whose contribution rate exceeds 85%. The specific contribution rate can also be selected based on the demand in the actual application process, and the embodiments of the application do not make specific limitations.
[0100] [According to Rule 26, the correction is made on 19.12.2025] After the above steps b1 to b4, the principal component score matrix can be obtained, and the dimensionality reduction of the standardized data matrix is realized through the principal component score matrix, so as to obtain the reduced data set.
[0101] [According to Rule 26, the correction is made on 19.12.2025] The reduced data set is represented by formula (4): Y=XP (4)
[0102] [According to Rule 26, corrected on 19.12.2025] Wherein Y is the reduced dimension data set, X is the data set obtained by standardizing the water chemical indicators of the plurality of water samples, and P is the principal component score matrix.
[0103] [According to Rule 26, corrected on 19.12.2025] Wherein each principal component in the principal component score matrix is represented by formula (5): F m = p m1 X1+p m2 X2+…+p mp X p (5)
[0104] [According to Rule 26, corrected on 19.12.2025] Wherein F m is the mth principal component, p m1 to p mp is the principal component score corresponding to each indicator of the mth principal component (i.e. the mth row of the principal component matrix), X1 to X p is the standardized value of the 1st to pth indicators of the n samples, i.e. the 1st to pth columns of the matrix X.
[0105] [According to Rule 26, corrected on 19.12.2025] S23, training the preset model according to the reduced dimension data set to obtain a water source discrimination model.
[0106] [According to Rule 26, corrected on 19.12.2025] Wherein the preset model can be a random forest model;
[0107] [According to Rule 26, corrected on 19.12.2025] In some embodiments, the above step S23 can further include the following steps:
[0108] [According to Rule 26, corrected on 19.12.2025] S231, inputting the reduced dimension data set into the preset model for training;
[0109] [According to Rule 26, corrected on 19.12.2025] S232, optimizing the number and depth of the random forest model sub-tree through the intelligent swarm optimization algorithm to obtain the water source discrimination model.
[0110] [According to Rule 26, correct 19.12.2025] Specifically, after inputting the dimensionality-reduced dataset into the random forest model, K-fold cross-validation can be used to divide the dataset, with the Kth fold as the test set, where K can be any positive integer less than the number of data in the dataset. After taking the Kth fold as the test set, the remaining K-1 folds can be used as the training set, and this process is repeated K times. In the random forest model classifier, bootstrap sampling is performed on the training set, the Gini index is used to select the best split feature during feature selection, the Classification And Regression Tree (CART) algorithm is used to construct the decision tree, and the test set is predicted based on the voting results of the decision tree.
[0111] [According to Rule 26, correct 19.12.2025] At the same time, the number of random forest sub-trees n_estimators and depth can be optimized by intelligent swarm optimization algorithm, here the Artificial Fish Swarms Algorithm (AFSA) is used. In AFSA, the state (current position) of each artificial fish is X i = (n_estimators, depth), and the food concentration (fitness) of the current position of the artificial fish is the average accuracy of the RF classifier after K-fold cross-validation. First, the positions of all artificial fish in AFSA are initialized, and then the four behaviors of foraging, grouping, following and random are executed according to the current fitness, and the maximum iteration number is taken as the termination condition of the algorithm.
[0112] [According to Rule 26, correct 19.12.2025] Figure 4 is a schematic diagram of the performance comparison of the RF model actually measured under different index systems. The performance test is carried out under four different index datasets, including accuracy, precision, recall and f1 score. The performance of different models for water source type identification is compared based on the inorganic index discrimination provided in the embodiment of the application, and the performance of different models for water source type identification is compared based on the inorganic index discrimination provided in the embodiment of the application. Figure 6 is a schematic diagram of the performance of the traditional RF model under different index datasets. Figure 7 is a schematic diagram of the performance of the RF model improved based on AFSA in the embodiment of the application under different index datasets.
[0113] [According to Rule 26, correct 19.12.2025] As shown in Figure 4, the combination of inorganic indicators and organic indicators can significantly improve the accuracy of water source discrimination. At the same time, AFSA can further improve the accuracy of the RF model.
[0114] [According to Rule 26 Correction 19.12.2025] Figure 5 is a schematic diagram of the results of actual testing of different model discrimination of water source types in embodiments of the application. Among them, the sample water sources include 74, Figure 8 is a schematic diagram of the results of water source type identification by a traditional RF model, and Figure 9 is a schematic diagram of the results of water source type identification by an RF model improved based on AFSA in embodiments of the application.
[0115] [According to Rule 26 Correction 19.12.2025] As can be seen from Figures 8 to 9, the traditional RF model has 2 misjudgments in identifying the water source types of 74 samples. However, the RF model improved based on AFSA provided in embodiments of the application has only 1 misjudgment. This fully reflects the performance advantages of the RF model improved based on AFSA.
[0116] [According to Rule 26 Correction 19.12.2025] In embodiments of the application, the water source type of the water source sample to be discriminated is identified by the water source discrimination model according to the multiple inorganic indexes and multiple organic indexes contained in the water chemical indexes of the water source sample to be discriminated. In this way, on the basis of inorganic index discrimination, the addition of organic indexes solves the problem that inorganic water chemical indexes are difficult to accurately discriminate similar water samples, and improves the accuracy of water source category judgment. At the same time, the RF is optimized using AFSA, and the improved algorithm has good global search ability and convergence, improving the efficiency in the process of model parameter optimization.

Therefore, after obtaining the water source discrimination model, the performance of the water source discrimination model can be detected by the above method, and the accuracy of the water source discrimination result output by the water source discrimination model is used to detect the performance of the model. Only when the performance of the water source discrimination model meets the requirements, the model is output for actual use.
