Description

Technical Field

[0001] This invention relates to the field of mine production technology, specifically to a mine water geological parameter monitor. Background Technology

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

[0003] Existing technologies suffer from the following main problems: 1. Lack of comprehensive monitoring data: Most mine water quality monitoring focuses only on certain water quality indicators, such as water temperature, pH, and conductivity, neglecting the impact of important parameters such as gases and hydraulics. For example, changes in the concentration of gases such as methane and carbon dioxide may lead to mine 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 flooding. 2. Delayed data analysis: Traditional monitoring methods generally rely on manual collection, measurement, and analysis of data, and the analysis results are often delayed, failing to detect potential mine water geological problems in a timely manner. 3. Lack of early warning mechanisms: Existing mine water geological monitoring systems lack a comprehensive early warning mechanism, making it difficult to promptly alert relevant personnel to take measures, resulting in difficulties in timely rescue and relief efforts after an accident.

[0004] With the rapid development of IoT, sensor technology, and artificial intelligence, new approaches have been provided to address the aforementioned problems in mine water geological monitoring. Existing related technological development directions include: IoT-based remote monitoring: utilizing sensor networks, IoT platforms, and cloud computing to achieve remote real-time monitoring and data transmission of mine water geological parameters, improving the accuracy and real-time nature of monitoring data. Intelligent data analysis: using machine learning, data mining, and other artificial intelligence technologies to intelligently analyze monitoring data, extract hidden patterns, predict future water geological trends, and issue early warning signals. Intelligent platform integration: establishing an integrated platform that combines multiple elements such as water quality, gas parameters, and hydraulic parameters to achieve an integrated platform for mine water geological monitoring, analysis, early warning, and decision-making. However, existing technologies still have many shortcomings, such as a lack of comprehensive analysis of multiple parameters and an imperfect early warning mechanism, which require further research and improvement.

[0005] Therefore, this invention aims to address the shortcomings of existing technologies by comprehensively analyzing the water quality, gas, and hydraulic parameters of each monitoring point at each monitoring period corresponding to mine water geology. This effectively assesses the mine water quality status, mine safety, and water hazard risks, and generates early warning signals in real time, providing a scientific basis for mine water resource management and ensuring safe mine production. Summary of the Invention

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

[0007] To achieve the above objectives, the present invention provides the following technical solution: a mine water geological parameter monitor, comprising 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 acquire the water geological parameters of each monitoring point in the mine water geological field during each monitoring period in real time, and obtain the water geological parameters of each monitoring point in the mine water geological field during each monitoring period.

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

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

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

[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 of each monitoring point corresponding to mine water geology during each monitoring period, and to obtain the early warning signal of each monitoring point corresponding to mine water geology during each monitoring period.

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

[0014] The water quality parameters for each monitoring point and monitoring period corresponding to the geological conditions of mine water include the water temperature, pH value, conductivity, dissolved oxygen content, suspended solids content, and turbidity value of the mine water.

[0015] The gas parameters for each monitoring point and 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 each monitoring point at each monitoring period in the mine water geology include water inflow, water level, water storage volume, and drainage flow.

[0017] Furthermore, the method for comprehensively analyzing the water quality parameters of each monitoring point at each monitoring period 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 difference between the water temperature values ​​at monitoring time points t1 and t2 is calculated and then divided by the difference between t1 and t2 to obtain the water temperature change rate of each monitoring point in each monitoring period.

[0019] The normal water temperature range [Tmin, Tmax] of each monitoring point in the mine water geology is obtained from the database. The difference between the water temperature value of each monitoring point in the mine water geology and the minimum value of the normal water temperature range is calculated and then divided by the difference between the maximum and minimum values ​​in the normal water temperature range to obtain the standardized water temperature value of each monitoring point in 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 and each monitoring period were calculated for the mine water geology.

[0021] The comprehensive water quality index for each monitoring point and monitoring period corresponding to the above parameters was calculated. Water temperature influence index at each monitoring point and during each monitoring period corresponding to mine water geology

[0022] According to the formula The influence coefficient η of water quality status at each monitoring point and during each monitoring period was calculated for mine water geology. b1 and b2 represent the weighting 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 at each monitoring point and during each monitoring period corresponding to the mine water geology is as follows:

[0024] Similarly, using the standardized calculation method for water temperature, 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 the mine water geology are calculated for each monitoring period. Based on the above parameters, the mine safety assessment coefficient μ of each monitoring point in the mine water geology is calculated for each monitoring period.

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

[0026] The standard deviation of the water inflow at each monitoring point for each monitoring period was calculated using the standard deviation calculation formula. The resulting standard deviation of the water inflow at each monitoring point for each monitoring period is denoted as:

[0027] 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 were obtained. The difference between the water level values ​​at monitoring time points t3 and t4 was calculated and divided by the difference between t3 and t4 to obtain the water level change rate of each monitoring period in each monitoring point corresponding to the mine water geology. Then, the sum of the water level change rates of each monitoring time point in the monitoring period [t5, t6] was obtained. The sum of the water level change rates was compared with the total number of each monitoring time point to obtain the average water level change rate of each monitoring period in each monitoring point corresponding to the mine water geology.

[0028] The water storage volume of each monitoring point in the mine water geology is calculated for each monitoring period, and the surface area of ​​the water storage space in each monitoring point in the mine water geology is calculated for each monitoring period based on the water storage volume of each monitoring point in the mine water geology.

[0029] The water inrush intensity index γ of each monitoring point during each monitoring period was calculated based on the above parameters.

[0030] The average drainage flow rate of each monitoring point for each monitoring period in the mine water geology is obtained by summing the drainage flow rates of each monitoring point for each monitoring period and dividing the sum by the total number of each monitoring period.

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

[0032] Retrieve 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 point in the mine water geology was calculated based on the above parameters for each monitoring period.

[0034] According to the formula Calculate the water hazard risk assessment coefficient for each monitoring point and 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 at each monitoring point and during each monitoring period for mine water geology is conducted as follows:

[0036] The influence coefficient of water quality status at each monitoring point in the mine water geology is compared with the preset threshold of water quality status influence coefficient. If the influence coefficient of water quality status at each monitoring point in the mine water geology is greater than the preset threshold of water quality status influence coefficient, an abnormal mine water signal is generated.

[0037] The mine safety assessment coefficients for each monitoring point in the mine water geology are compared with the preset mine safety assessment coefficient thresholds for each monitoring period. If the mine safety assessment coefficients for each monitoring point in the mine water geology are greater than the preset mine safety assessment coefficient thresholds for each monitoring period, an abnormal production signal is generated.

[0038] The water hazard risk assessment coefficients for each monitoring point and each monitoring period corresponding to the mine water geology are plotted as a scatter plot. A straight line is drawn on (0,1) of the scatter plot and recorded as the risk assessment line. If the dispersion distance of the water hazard risk assessment coefficient scatter points for each monitoring point and each monitoring period corresponding to the mine water geology deviates from the risk assessment line by more than 2, it indicates that the drainage system of the mine is inefficient and there is a risk of water hazard, and a water hazard early warning signal is generated. At the same time, for monitoring periods in which the dispersion points of the water hazard risk assessment coefficients show a progressive increase for 5 consecutive monitoring periods, a drainage anomaly signal is generated.

[0039] The beneficial effects of this invention are:

[0040] 1. In this invention, by installing suitable sensors at various monitoring points corresponding to mine water geology and connecting them to a mine water geology parameter monitor, real-time monitoring and acquisition of water quality, gas, and hydraulic parameters at each monitoring point during each monitoring period can be achieved. The mine water geology parameter monitor can monitor the temperature, pH value, conductivity, dissolved oxygen content, and suspended solids content of mine water in real time, as well as methane concentration, carbon dioxide concentration, oxygen concentration, and gas release rate. In addition, it can also monitor water inflow, water level, water storage volume, and drainage flow, providing accurate and reliable data support for mine water management.

[0041] 2. This invention comprehensively analyzes the water quality parameters at each monitoring point and during each monitoring period corresponding to the geological conditions of mine water. This allows for an accurate assessment of the water quality status at each monitoring point and during each monitoring period. Based on the calculated water temperature change rate and standardized parameter values ​​for each monitoring period, and using preset weighting factors and dynamic adjustment parameters, the comprehensive water quality index and water temperature influence index at each monitoring point and during each monitoring period are calculated. Finally, based on the calculated comprehensive information, a comprehensive evaluation coefficient for the impact of mine water quality status is derived. This provides a comprehensive understanding of the changes in mine water quality and offers scientific and accurate data support for the analysis of the impact of geological changes in mine water.

[0042] 3. In this invention, by calculating and analyzing the gas and water quality parameters at each monitoring point during each monitoring period corresponding to the mine water geology, the safety of the mine can be effectively assessed. By obtaining parameters such as methane concentration, carbon dioxide concentration, oxygen concentration, gas release rate, water turbidity, and water temperature, and standardizing these parameters to obtain standardized methane concentration, standardized carbon dioxide concentration, standardized oxygen concentration, standardized gas release rate, and standardized water turbidity values, and then, according to specific weighting factors, these standardized values ​​are weighted and calculated to finally obtain the mine safety assessment coefficient. This allows for timely monitoring of changes in the mine water geological environment, and the safety level of the mine can be determined based on the assessment coefficient value, thereby enabling the implementation of necessary safety measures to ensure safe production in the mine.

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

[0073] The water temperature values ​​at time points t1 and t2 within the monitoring period [t1, t2] are obtained at each monitoring point corresponding to the mine water geology. The difference between the water temperature values ​​at monitoring time points t1 and t2 is calculated and divided by the difference between t1 and t2 to obtain the rate of change of water temperature for each monitoring period at each monitoring point corresponding to the mine water geology, denoted as DT. ij i represents the number of each monitoring point, i = 1, 2, ..., n, n represents the total number of monitoring point numbers, j represents the number of each monitoring period, j = 1, 2, ..., m, m represents the total number of monitoring period numbers;

[0075] Similarly, the standardized pH, standardized conductivity, standardized dissolved oxygen content, and standardized suspended solids content at each monitoring point and time period corresponding to the mine water geology were calculated and denoted as Ps. ij Cs ij 、Ds ij and Ss ij ;

[0076] According to the formula Calculate the comprehensive water quality index for each monitoring point and each monitoring period corresponding to the mine water geology. a1, a2, a3, and a4 represent the corresponding weighting factors, and a1 + a2 + a3 + a4 = 1, where e is a natural constant. Specifically, a1 = 0.25, a2 = 0.20, a3 = 0.35, and a4 = 0.20. The corresponding weighting factors are dynamically adjusted based on the evaluation emphasis of standardized pH, standardized conductivity, standardized dissolved oxygen content, and standardized suspended solids content at each monitoring point and monitoring period corresponding to the mine water geology.

[0077] According to the formula Calculate the water temperature influence index at each monitoring point for each monitoring period corresponding to the mine water geology. k represents an adjustment parameter; specifically, when the rate of change of water temperature is large, k will also increase accordingly.

[0078] According to the formula The influence coefficient η of water quality status at each monitoring point for each monitoring period was calculated. b1 and b2 represent the weighting factors corresponding to the comprehensive water quality index and the water temperature influence index, respectively. Specifically, b1 = 1.56 and b2 = 2.31.

[0079] In one specific embodiment, this invention comprehensively analyzes the water quality parameters of each monitoring point and each monitoring period corresponding to the mine water geology. This allows for an accurate assessment of the water quality status at each monitoring point and each monitoring period. Based on the calculated water temperature change rate and standardized parameter values ​​for each monitoring period, and then using preset weighting factors and dynamic adjustment parameters, the comprehensive water quality index and water temperature influence index for each monitoring point and each monitoring period are calculated. Finally, based on the calculated comprehensive information, a comprehensive evaluation coefficient for the mine water quality status is derived. This provides a comprehensive understanding of the mine water quality changes and offers scientific and accurate data support for the analysis of the impact of mine water geological changes.

[0080] The mine safety analysis module is used to calculate and analyze the gas parameters at each monitoring point for each monitoring period corresponding to the mine water geology, and to obtain the mine safety assessment coefficient for each monitoring point for each monitoring period. The specific calculation and analysis method is as follows:

[0081] The methane concentration, carbon dioxide concentration, oxygen concentration and gas release rate were obtained from the gas parameters of each monitoring point in the mine water geology at each monitoring period. At the same time, the turbidity value of the water body was obtained from the water quality parameters of each monitoring point in the mine water geology at each monitoring period.

This is achieved by acquiring parameters such as methane concentration, carbon dioxide concentration, oxygen concentration, gas release rate, water turbidity, and water temperature, and then standardizing these parameters to obtain standardized methane concentration, standardized carbon dioxide concentration, standardized oxygen concentration, standardized gas release rate, and standardized water turbidity values. These standardized values ​​are then weighted according to specific weighting factors to obtain a final mine safety assessment coefficient. This allows for timely monitoring of changes in the mine water geological environment and judgment of the mine's safety level based on the assessment coefficient, enabling the implementation of necessary safety measures to ensure safe mine production.

[0085] The water hazard risk assessment module is used to comprehensively analyze the hydraulic parameters of each monitoring point in the mine water geology for each monitoring period, and obtain the water hazard risk assessment coefficient for each monitoring point in the mine water geology for each monitoring period. The specific analysis method is as follows:

[0086] The water inflow, water level, water storage volume and drainage flow rate are obtained from the hydraulic parameters of each monitoring point and each monitoring period corresponding to the mine water geology.

[0087] The standard deviation of the water inflow at each monitoring point for each monitoring period was calculated using the standard deviation calculation formula. The resulting standard deviation of the water inflow at each monitoring point for each monitoring period is denoted as:

[0088] It should be noted that the water inflow at each monitoring point during each monitoring period corresponding to the mine water geology is denoted as Y. ij The average water inflow rate at each monitoring point during each monitoring period corresponding to the mine water geology is denoted as YP. ij The formula for calculating the standard deviation of water inflow at each monitoring point and during each monitoring period for mine water geology is as follows: g represents the total number of monitoring time points in each monitoring period.

[0089] The water level values ​​at time points t3 and t4 within the monitoring period [t3, t4] are obtained for each monitoring point corresponding to the mine water geology. The difference between the water level values ​​at time points t3 and t4 is calculated and divided by the difference to obtain the water level change rate for each monitoring period at each monitoring point. Then, the sum of the water level change rates at each monitoring time point within the monitoring period [t5, t6] is obtained. The sum of the water level change rates is compared with the total number of all monitoring time points to obtain the average water level change rate for each monitoring period at each monitoring point, denoted as WT. ij ;

[0090] The water storage volume at each monitoring point corresponding to the mine water geology during each monitoring period is denoted as V. ij Simultaneously, the surface area of ​​the water storage space at each monitoring point during each monitoring period was calculated based on the water storage volume at each monitoring period corresponding to the mine water geology, and denoted as S. ij ;

[0091] According to the formula The water inflow intensity index γ is calculated for each monitoring point and each monitoring period corresponding to the mine water geology. f represents an adjustment parameter; specifically, the specific value of f can be determined through experiments or experience based on the actual situation, and is used to balance the influence of the water storage space volume on the water inflow intensity.

[0092] The drainage flow rate at each monitoring point corresponding to the mine water geology during each monitoring period is denoted as P. ij The average drainage flow rate of each monitoring point in the mine water geology corresponding to each monitoring period is obtained by summing the drainage flow rate of each monitoring period and dividing it by the total number of each monitoring period. This average value is denoted as Pc.

[0093] The initial drainage capacity of the drainage equipment corresponding to the mine water geology is obtained from the database. The actual drainage capacity of the drainage equipment for each monitoring period is obtained by multiplying the initial drainage capacity of the drainage equipment by the performance attenuation coefficient α, which is denoted as Pa. The performance attenuation coefficient is 0≤α≤1.

[0094] Retrieve the preset drainage equipment failure rate from the database, denoted as β, where 0≤β≤1;

[0095] According to the formula The drainage efficiency coefficient λ of each monitoring point in the mine water geology was calculated for each monitoring period.

[0096] According to the formula Calculate the water hazard risk assessment coefficient for each monitoring point and each monitoring period corresponding to the mine water geology.

[0097] In one specific embodiment, the present invention comprehensively analyzes the hydraulic parameters of each monitoring point and each monitoring period corresponding to the mine water geology to obtain the water hazard risk assessment coefficient for each monitoring point and each monitoring period corresponding to the mine water geology, 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 at each monitoring point corresponding to mine water geology for each monitoring period, and to obtain the early warning signal for each monitoring point corresponding to mine water geology for each monitoring period. The specific comparative analysis method is as follows:

[0099] The influence coefficient of water quality status at each monitoring point in the mine water geology is compared with the preset threshold of water quality status influence coefficient. If the influence coefficient of water quality status at each monitoring point in the mine water geology is greater than the preset threshold of water quality status influence coefficient, an abnormal mine water signal is generated.

[0100] The mine safety assessment coefficients for each monitoring point in the mine water geology are compared with the preset mine safety assessment coefficient thresholds for each monitoring period. If the mine safety assessment coefficients for each monitoring point in the mine water geology are greater than the preset mine safety assessment coefficient thresholds for each monitoring period, an abnormal production signal is generated.

[0101] The water hazard risk assessment coefficients for each monitoring point and each monitoring period corresponding to the mine water geology are plotted as a scatter plot. At the same time, a straight line is drawn on (0,1) of the scatter plot and recorded as the risk assessment line. If the dispersion distance of the water hazard risk assessment coefficient scatter points for each monitoring point and each monitoring period corresponding to the mine water geology deviates from the risk assessment line by more than 2, it indicates that the drainage system of the mine is inefficient and there is a risk of water hazard, and a water hazard early warning signal is generated. At the same time, for monitoring periods in which the dispersion points of the water hazard risk assessment coefficients show a progressive increase for 5 consecutive monitoring periods, a drainage anomaly signal is generated.

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

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

[0104] The above formulas are all dimensionless calculations. The formulas are derived from software simulations based on a large amount of collected data to obtain the most recent real-world results.
