Description

Technical Field

[0001] The invention relates to the technical field of mine production, in particular to a mine water geological parameter monitor. Background Art

[0002] Mine water treatment has always been a key technology to ensure safe production and environmental protection in mines. Due to the complex geological dynamics of mine water and the large potential for accidents, traditional on-site monitoring and fixed-point sampling methods are difficult to meet the needs of real-time and accurate monitoring.

[0003] The existing related technologies mainly have the following problems: 1. Lack of comprehensiveness of monitoring data: Most mine water quality monitoring only focuses on some water quality indicators, such as measuring water temperature, pH, conductivity, etc., and ignores the influence of important parameters such as gas and hydraulics. For example, changes in the concentration of gases such as methane and carbon dioxide may cause mines to be prone to explosions or poisoning accidents, while changes in hydraulic parameters such as water inflow and water level may lead to safety risks such as mine rock collapse or flood disasters. 2. Lag in monitoring data analysis: Traditional monitoring methods generally rely on manual collection, measurement and analysis of data, and the analysis results often lag, making it impossible to detect potential mine water geological problems in a timely manner. 3. Lack of early warning mechanism: The existing mine water geological monitoring system lacks a complete early warning mechanism, making it difficult to remind relevant personnel to take measures in a timely manner, resulting in difficulty in timely rescue after an accident occurs.

[0004] With the rapid development of Internet of Things technology, sensor technology and artificial intelligence, new ideas have been provided to solve the above problems of mine water geological monitoring. Existing relevant technical development directions: Remote monitoring based on the Internet of Things: Use sensor networks, Internet of Things platforms and cloud computing technologies to realize remote real-time monitoring and data transmission of mine water geological parameters, and improve the accuracy and real-time nature of monitoring data. Intelligent data analysis: Use artificial intelligence technologies such as machine learning and data mining to intelligently analyze monitoring data, extract hidden laws, predict future water geological trends, and issue early warning signals. Intelligent platform integration: Establish an integrated platform that integrates multiple factors such as water quality, gas parameters, hydraulic parameters, etc., to realize the construction of an integrated platform for mine water geological monitoring, analysis, early warning and decision-making. However, there are still many shortcomings in the existing technology, such as the lack of comprehensive analysis of multiple parameters and imperfect early warning mechanisms, which require further research and improvement.

[0005] Therefore, the present invention aims to solve the deficiencies in the prior art by comprehensively analyzing the water quality, gas, and hydraulic parameters in each monitoring period at each monitoring point corresponding to mine water geology, effectively evaluating the mine water quality status, mine safety, and water hazard risks, and generating early warning signals in real time, thereby providing a scientific basis for mine water resources management and ensuring safe mine production. Summary of the invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a mine water geological parameter monitor to solve the above-mentioned technical defects.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: a mine water geological parameter monitor, including a mine water geological parameter module, a water quality status analysis module, a mine safety analysis module, a water hazard risk assessment module, a monitoring and early warning terminal, and a database.

[0008] The mine water geological parameter module is used to monitor and obtain the water geological parameters of each monitoring point in each monitoring period of the mine water geology in real time, and obtain the water geological parameters of each monitoring point in each monitoring period of the mine water geology;

[0009] The water quality status analysis module is used to comprehensively analyze the water quality parameters of each monitoring point in each monitoring period corresponding to the mine water geology, and obtain the water quality status influence coefficient of each monitoring point in each monitoring period corresponding to the mine water geology;

[0010] The mine safety analysis module is used to calculate and analyze the gas parameters of each monitoring point in each monitoring period corresponding to the mine water geology, and obtain the mine safety assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology;

[0011] The water hazard risk assessment module is used to comprehensively analyze the hydraulic parameters of each monitoring point in each monitoring period corresponding to the mine water geology, and obtain the water hazard risk assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology;

[0012] The monitoring and early warning terminal is used to compare and analyze the water quality status influence coefficient, mine safety assessment coefficient and water hazard risk assessment coefficient in each monitoring period at each monitoring point corresponding to the mine water geology, and obtain the early warning signal in each monitoring period at each monitoring point corresponding to the mine water geology.

[0013] Furthermore, the water geological parameters corresponding to each monitoring point in each monitoring period of the mine water geology include water quality parameters, gas parameters and hydraulic parameters;

[0014] The water quality parameters of each monitoring point in each monitoring period corresponding to the mine water geology include the water temperature, pH value, conductivity, dissolved oxygen content, suspended matter content and water turbidity value of the mine water;

[0015] The gas parameters of each monitoring point in each monitoring period corresponding to the mine water geology include methane concentration, carbon dioxide concentration, oxygen concentration and gas release rate;

[0016] The hydraulic parameters of mine water geology corresponding to each monitoring point in each monitoring period include water inflow, water level, water storage volume and drainage flow.

[0017] Furthermore, the method of comprehensively analyzing the water quality parameters of each monitoring period at each monitoring point corresponding to the mine water geology is as follows:

[0018] The water temperature values ​​at time points t1 and t2 in the monitoring period [t1, t2] of each monitoring point corresponding to the mine water geology are obtained respectively, the water temperature values ​​at the monitoring time points t1 and t2 are calculated by the difference between t1 and t2, and the water temperature change rate in each monitoring period of each monitoring point corresponding to the mine water geology is obtained;

[0019] The preset normal water temperature value range of each monitoring point in each monitoring period corresponding to the mine water geology is obtained from the database as [Tmin, Tmax], and the water temperature value in each monitoring period at each monitoring point corresponding to the mine water geology is calculated with the minimum value of the normal water temperature range, and then divided by the difference between the maximum value and the minimum value in the normal water temperature range to obtain the standardized water temperature value in each monitoring period at each monitoring point corresponding to the mine water geology;

[0020] Similarly, the standardized pH value, standardized conductivity, standardized dissolved oxygen content and standardized suspended solids content of each monitoring point in each monitoring period of the mine water geology are calculated;

[0021] The above parameters are used to calculate the comprehensive water quality index of each monitoring point in each monitoring period in the mine water geology. The water temperature impact index of each monitoring point and each monitoring period corresponding to the mine water geology

[0022] According to the formula The water quality status influence coefficient η of each monitoring point in each monitoring period corresponding to the mine water geology is calculated, and b1 and b2 represent the weight factors corresponding to the comprehensive water quality index and the water temperature influence index respectively.

[0023] Furthermore, the method for calculating and analyzing the gas parameters in each monitoring period at each monitoring point corresponding to the mine water geology is as follows:

[0024] Similarly, the standardized calculation method of water temperature value is used to calculate the standardized methane concentration, standardized carbon dioxide concentration, standardized oxygen concentration, standardized gas release rate and standardized water turbidity value of each monitoring point in each monitoring period corresponding to the mine water geology. The mine safety assessment coefficient μ of each monitoring point in each monitoring period corresponding to the mine water geology is calculated through the above parameters.

[0025] Furthermore, the method for comprehensively analyzing the hydraulic parameters of each monitoring point in each monitoring period corresponding to the mine water geology is as follows:

[0026] The standard deviation of the water inflow in each monitoring period at each monitoring point corresponding to the mine water geology is calculated by the standard deviation calculation formula, and the standard deviation of the water inflow in each monitoring period at each monitoring point corresponding to the mine water geology is obtained, which is recorded as

[0027] Respectively obtain the water level values ​​at time points t3 and t4 in the monitoring period [t3, t4] of each monitoring point corresponding to the mine water geology, calculate the difference between the water level values ​​at the monitoring time points t3 and t4, and divide by the difference between t3 and t4 to obtain the water level change rate in each monitoring period of each monitoring point corresponding to the mine water geology, then obtain the sum of the water level change rates at each monitoring time point in the monitoring period [t5, t6], compare the sum of the water level change rates with the total number of each monitoring time point, and obtain the average value of the water level change rate in each monitoring period of each monitoring point corresponding to the mine water geology;

[0028] The water storage volume of each monitoring point in each monitoring period corresponding to the mine water geology is calculated, and the surface area of ​​the water storage space of each monitoring point in each monitoring period corresponding to the mine water geology is calculated by the water storage volume of each monitoring point in each monitoring period corresponding to the mine water geology;

[0029] The water inflow intensity index γ of each monitoring point in each monitoring period corresponding to the mine water geology is calculated through the above parameters;

[0030] The drainage flow rate of each monitoring period in each monitoring point corresponding to the mine water geology is obtained by summing up the drainage flow rate of each monitoring period in each monitoring point corresponding to the mine water geology and dividing it by the total number of each monitoring period to obtain the average drainage flow rate of each monitoring period in each monitoring point corresponding to the mine water geology;

[0031] The initial drainage capacity of the drainage equipment corresponding to the mine water geology is obtained from the database, and the actual drainage capacity of the drainage equipment corresponding to each monitoring period is obtained by multiplying the initial drainage capacity of the drainage equipment by the performance attenuation coefficient α, which is recorded as Pa;

[0032] Obtain the preset drainage equipment failure rate from the database, denoted as β, where 0≤β≤1;

[0033] The drainage efficiency coefficient λ of each monitoring period in each monitoring point corresponding to the mine water geology is calculated through the above parameters;

[0034] According to the formula Calculate the water hazard risk assessment coefficient for each monitoring point in each monitoring period corresponding to the mine water geology

[0035] Furthermore, the comparative analysis of the water quality status influence coefficient, mine safety assessment coefficient and water hazard risk assessment coefficient in each monitoring period at each monitoring point corresponding to the mine water geology is as follows:

[0036] The water quality state influence coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is compared with the preset water quality state influence coefficient threshold value. If the water quality state influence coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is greater than the preset water quality state influence coefficient threshold value, a mine water abnormal signal is generated;

[0037] The mine safety assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is compared with the preset mine safety assessment coefficient threshold. If the mine safety assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is greater than the preset mine safety assessment coefficient threshold, an abnormal production signal is generated;

[0038] The water hazard risk assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is plotted into a scatter plot, and a straight line is drawn on (0,1) of the scatter plot, and the straight line is recorded as the risk assessment line. If the discrete distance of the water hazard risk assessment coefficient scatter points in each monitoring point in each monitoring period corresponding to the mine water geology deviates from the risk assessment line by more than 2, it means that the drainage system of the mine is inefficient and there is a water hazard risk, and a water hazard warning signal is generated; at the same time, for the monitoring period in which the water hazard risk assessment coefficient scatter points in five consecutive monitoring periods show a progressive increase, a drainage abnormality signal is generated.

[0039] Beneficial effects of the present invention:

In the present invention, by installing appropriate sensors at each monitoring point corresponding to the mine water geology and communicating with the mine water geological parameter monitor, it is possible to achieve real-time monitoring and acquisition of water quality, gas, and hydraulic parameters in each monitoring period at each monitoring point of the mine water geology. The mine water geological parameter monitor can monitor the temperature, pH value, conductivity, dissolved oxygen content, and suspended matter content of the mine water in real time, as well as the methane concentration, carbon dioxide concentration, oxygen concentration, and gas release rate. In addition, it can also monitor the water inflow, water level, water storage volume, and drainage flow, providing accurate and reliable data support for mine water management.

[0041] 2. In the present invention, by comprehensively analyzing the water quality parameters of each monitoring period in each monitoring point corresponding to the mine water geology, the water quality status of each monitoring period in each monitoring point corresponding to the mine water geology can be accurately evaluated. According to the calculated water temperature change rate and each parameter value after standardization in each monitoring period, and then according to the preset weight factor and dynamic adjustment parameter, the water quality comprehensive index and water temperature influence index of each monitoring period in each monitoring point corresponding to the mine water geology are calculated. Finally, according to the calculated comprehensive information, the comprehensive evaluation coefficient of the mine water quality status is obtained, so as to fully grasp the mine water quality change status and provide scientific and accurate data support for the impact analysis of mine water geological changes.

[0042] 3. In the present invention, by calculating and analyzing the gas and water quality parameters of each monitoring point in each monitoring period corresponding to the mine water geology, the safety of the mine can be effectively evaluated. By obtaining parameters such as methane concentration, carbon dioxide concentration, oxygen concentration, gas release rate, water turbidity, water temperature, etc., and standardizing these parameters, standardized methane concentration, standardized carbon dioxide concentration, standardized oxygen concentration, standardized gas release rate and standardized water turbidity values ​​are obtained. Then, according to a specific weight factor, these standardized values ​​are weighted and calculated to finally obtain a mine safety assessment coefficient. The changes in the mine water geological environment can be timely grasped, and the safety level of the mine can be judged according to the numerical value of the assessment coefficient, so as to take necessary safety measures to ensure safe production in the mine.

[0043] 4. In the present invention, by comprehensively analyzing the hydraulic parameters of each monitoring point corresponding to the mine water geology in each monitoring period, the water hazard risk assessment coefficient of each monitoring point corresponding to the mine water geology in each monitoring period can be obtained, thereby providing a scientific basis for mine safety prevention and control.

[0098] The monitoring and early warning terminal is used to compare and analyze the water quality status influence coefficient, mine safety assessment coefficient and water hazard risk assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology, and obtain the early warning signal of each monitoring point in each monitoring period corresponding to the mine water geology. The specific comparative analysis method is as follows:

[0099] The water quality state influence coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is compared with the preset water quality state influence coefficient threshold value. If the water quality state influence coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is greater than the preset water quality state influence coefficient threshold value, a mine water abnormal signal is generated;

[0100] The mine safety assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is compared with the preset mine safety assessment coefficient threshold. If the mine safety assessment coefficient of each monitoring point in each monitoring period corresponding to the mine water geology is greater than the preset mine safety assessment coefficient threshold, an abnormal production signal is generated;

[0101] The water hazard risk assessment coefficients of each monitoring period at each monitoring point corresponding to the mine water geology are plotted into a scatter plot, and a straight line is drawn on (0,1) of the scatter plot, and the straight line is recorded as the risk assessment line. If the discrete distance of the water hazard risk assessment coefficients of each monitoring period at each monitoring point corresponding to the mine water geology deviates from the risk assessment line by more than 2, it means that the drainage system of the mine is inefficient and there is a water hazard risk, and a water hazard warning signal is generated; at the same time, for the monitoring period in which the water hazard risk assessment coefficients of the scatter points in five consecutive monitoring periods show a progressive increase, a drainage abnormality signal is generated;

[0102] The mine water geological parameter monitor takes corresponding inspection measures according to the type of early warning signal received, thereby ensuring the safe production of the mine.

[0103] The database is used to store the water geological parameters of each monitoring point in each monitoring period corresponding to the mine water geology.

[0104] The above formulas are all dimensionless and numerical calculations. The formula is a formula that is obtained by collecting a large amount of data and performing software simulation to obtain the most recent real situation. The size of the coefficient is to quantify each parameter to obtain a specific value. Regarding the size of the coefficient, it is acceptable as long as it does not affect the proportional relationship between the parameter and the quantified value.
