Description

Technical Field

[0001] The present application relates to the technical field of coal mine ventilator monitoring, and specifically relates to an online monitoring method, device, equipment and storage medium for a coal mine ventilator. Background Art

[0002] With the processes of industrialization and urbanization, the demand for mineral resources is continuously increasing. To meet this demand, people actively search for new mineral sources. After finding a new mineral source, in order to ensure safe and efficient mining, it is necessary to carefully construct a mine according to the actual location of the mineral source. After the mine is built, it is also necessary to flexibly adjust the mining strategy according to the changes in the mineral source to achieve the maximum utilization of resources.

[0003] During the operation of a mine, operations such as coal mining and transportation will generate a large amount of harmful gases and dust, such as gas, carbon monoxide and coal dust. These harmful gases and dust will not only harm the respiratory systems of miners, but also trigger serious accidents such as explosions. To effectively address this problem, coal mine ventilators are usually installed in mines. By continuously inhaling fresh air and discharging harmful gases and dust, coal mine ventilators can effectively reduce the concentration of harmful gases and the content of dust in the mine, thereby ensuring the physical health and life safety of miners. Based on the main role of coal mine ventilators in the safe production of mines, it is crucial to monitor their working status in real time. At present, the inspection of coal mine ventilators mainly relies on manual operation, which is inefficient and difficult to obtain the working status information of coal mine ventilators in a timely manner.

[0004] Therefore, there is an urgent need for an online monitoring method, device, equipment and storage medium for a coal mine ventilator that can solve the above technical problems. Summary of the Invention

[0005] The present application provides an online monitoring method, device, equipment and storage medium for a coal mine ventilator. The method automatically obtains the monitoring parameters of a target ventilator, determines the working status of the ventilator by establishing a ventilator performance function and inputting the monitoring parameters and the first gas concentration value into the ventilator performance function, which can improve the monitoring efficiency of the working status information of the coal mine ventilator and reduce the misjudgment of manual detection.

[0006] In the first aspect, the present application provides an online monitoring method for a coal mine ventilator, which is applied to a coal mine ventilator monitoring platform, and the method includes: obtaining monitoring parameters corresponding to the ventilation system in a target mine, the monitoring parameters being parameters for monitoring a target ventilator in the ventilation system; calculating a ventilation resistance coefficient based on the monitoring parameters and the target values ​​of the target mine; obtaining a first gas concentration value corresponding to the target mine; determining a performance function corresponding to the target ventilator based on the target mine; inputting the ventilation resistance coefficient and the first gas concentration value into the performance function to obtain the current working state of the target ventilator, the working state including a normal state and an abnormal state.

[0007] By adopting the above technical solution, the monitoring parameters of the ventilation system in the target mine are obtained, and the automatic monitoring of the ventilation system is realized, which avoids the efficiency of monitoring data acquisition during manual inspection. The monitoring data is then processed at a faster speed than manual processing. The ventilation resistance coefficient and the first gas concentration value are input into the performance function to quickly determine the working status of the target ventilator. This judgment method is more accurate and efficient, and can promptly detect abnormal conditions of the target ventilator. The automatic monitoring system can continuously monitor the target ventilator to reduce interference and errors caused by human factors.

[0008] Optionally, the ventilation resistance coefficient is calculated based on the monitoring parameters and the target values ​​of the target mine, specifically including: obtaining the monitoring parameters, the monitoring parameters include pipeline length parameters, pipeline diameter parameters, pipeline bending parameters and pipeline blockage parameters; obtaining the target values, the target values ​​include mine length values ​​and wind speed values; performing wind resistance calculation on the monitoring parameters and the target values ​​to obtain the ventilation resistance coefficient.

[0009] By adopting the above technical solution and conducting a comprehensive analysis of the monitoring data and target values, the ventilation resistance coefficient can be accurately calculated. Based on the calculated ventilation resistance coefficient, the pipe length, diameter, curvature and blockage parameters of the ventilation system can be optimized and adjusted, which helps to reduce ventilation resistance and improve ventilation efficiency, thereby ensuring air circulation and safety in the target mine.

[0010] Optionally, obtaining a first gas concentration value corresponding to the target mine specifically includes: obtaining multiple test positions of the target mine, the multiple test positions include working face positions, tunnel positions and ventilation opening positions; installing a target measurement device at the target position, the target position is any one of the multiple test positions, the target measurement device includes a gas concentration sensor, a gas detector, a mining lamp gas monitor and an optical methane detector; using the target measurement device to monitor the target position to obtain a first gas concentration value.

[0011] By adopting the above technical solution, multiple positions to be measured in the target mine are obtained, and target measuring devices are installed at the multiple positions to be measured. The target measuring devices are mainly used to monitor the gas concentration in the target mine and obtain the gas concentration in the target mine in real time. By selecting multiple positions to be measured, comprehensive monitoring of the gas concentration in the target mine can be realized, ensuring that there is no monitoring blind area. The first gas concentration value can timely reflect the safety status in the target mine and can effectively prevent the occurrence of safety accidents such as gas explosions.

[0012] Optionally, the ventilation resistance coefficient and the first gas concentration value are input into the performance function to obtain the current working state of the target ventilator, which specifically includes: inputting the ventilation resistance coefficient and the first gas concentration value into the performance function to obtain the first static pressure value; judging whether the first static pressure value is less than or equal to the second static pressure value, where the second static pressure value is the static pressure value actually provided by the target ventilator; when the first static pressure value is less than or equal to the second static pressure value, it is confirmed that the ventilation resistance of the target ventilator is in a normal state.

[0013] By adopting the above technical solution, the ventilation resistance coefficient and the first gas concentration value are input into the performance function to obtain the first static pressure value. By comparing the first static pressure value with the second static pressure value, it can be accurately judged whether the ventilation resistance of the target ventilator is in a normal state, which helps to calculate and discover abnormal ventilation resistance situations, timely monitor and evaluate the ventilation resistance state of the target ventilator, ensure good air circulation in the target mine, effectively reduce the risk of the first gas concentration accumulating in the target mine, and improve the safety level of the target mine.

[0014] Optionally, before judging whether the first static pressure value is less than or equal to the second static pressure value, the method further includes: obtaining the first air volume value, where the first air volume value is the air volume value required for the first gas concentration value; obtaining the second air volume value corresponding to the target ventilator; judging whether the first air volume value is less than or equal to the second air volume value; if the first air volume value is less than or equal to the second air volume value, it is confirmed to obtain the first static pressure value.

[0015] By adopting the above technical solution, the control of the first gas concentration value is not only related to the ventilation resistance but also closely related to the first air volume value. By comparing the first air volume value and the second air volume value, it can be ensured that the air volume provided by the target ventilator can meet the requirement of reducing the first gas concentration value. When the first air volume value is less than or equal to the second air volume value, it means that the actual air volume provided by the target ventilator can meet the air volume required to reduce the current first gas concentration value, and it is also necessary to obtain the first static pressure value, so as to ensure that while the target ventilator meets the air volume, its ventilation resistance is also in a normal state.

[0016] Optionally, after determining whether the first static pressure value is less than or equal to the second static pressure value, the method further includes: when the first static pressure value is greater than the second static pressure value, obtaining the first gas concentration value; determining whether the first gas concentration value is greater than the second gas concentration threshold, where the second gas concentration threshold is a pre-set safe gas concentration value; if the first gas concentration value is greater than the second gas concentration threshold, confirming that the target ventilator is in an abnormal state.

[0017] By adopting the above technical solution, when the first static pressure value is greater than the second static pressure value, that is, the static pressure output of the target ventilator is insufficient to overcome the ventilation resistance, the gas concentration in the target mine may rise. By comparing the first gas concentration value with the second gas concentration threshold, the abnormal situation of the ventilation system can be detected in time to prevent gas accumulation. The performance of the target ventilator and the gas concentration are two key factors for the safe production of the target mine. Combining the two can comprehensively evaluate the state of the target ventilator. When the target ventilator is in an abnormal state, corresponding safety measures need to be taken.

[0018] Optionally, after confirming that the target ventilator is in an abnormal state if the first gas concentration value is greater than the second gas concentration threshold, the method further includes: calculating the difference between the first gas concentration value and the second gas concentration threshold; determining the treatment measures according to the difference, where the treatment measures include the first treatment measure and the second treatment measure; when the difference is less than or equal to the preset value, confirming that the first treatment measure is taken for the target ventilator, and the first treatment measure includes stopping work; when the difference is greater than the preset value, confirming that the second treatment measure is taken for the target ventilator, and the second treatment measure includes evacuating the construction personnel and starting the emergency ventilation system.

[0019] By adopting the above technical solution, obtaining the difference between the first gas concentration value and the second gas concentration threshold and comparing the difference with the preset value can distinguish different levels of safety risks. When the difference is less than or equal to the preset value, the first treatment measure needs to be taken for the target ventilator. When the difference is greater than the preset value, the second treatment measure needs to be taken for the target ventilator. By taking the first treatment measure and the second treatment measure in time, the abnormal state of the target ventilator can be quickly responded to, preventing the gas concentration from continuing to rise and accumulate, and helping to reduce the risk of safety accidents such as gas explosion.

[0038] With the continuous advancement of industrialization and urbanization, the demand for mineral resources continues to climb. To meet this demand, people need to actively search for new mineral sources. After discovering a new mineral source, in order to ensure safe and efficient mining, we need to carefully construct a mine according to the actual location of the mineral source. After the mine is built, it is also necessary to flexibly adjust the mining strategy according to the changes in the mineral source to achieve the maximum utilization of resources.

[0039] During the mine operation process, a large amount of harmful gases and dust will be generated in the operation links such as coal mining and transportation, such as gas, carbon monoxide and coal dust. These harmful substances not only seriously threaten the respiratory health of miners, but may also cause serious safety accidents such as explosions. To effectively address this problem, we usually install coal mine ventilators in the mine. The ventilator continuously inhales fresh air and discharges harmful gases and dust, significantly reducing the concentration of harmful gases and the content of dust in the mine, thus ensuring the physical health and life safety of miners. Given the important role of coal mine ventilators in mine safety production, it is crucial to monitor their working status in real time. However, at present, the inspection of coal mine ventilators mainly relies on manual operation, which is inefficient and difficult to obtain the working status information of the ventilator in a timely manner.

[0040] Therefore, how to change the problem of the low efficiency of the existing manual inspection of coal mine ventilators. An online monitoring method for coal mine ventilators provided by the embodiments of the present application is applied to a coal mine ventilator monitoring platform. The coal mine ventilator monitoring platform of the present application can be a platform that provides ventilator monitoring services for coal mining enterprises. Figure 1 It is a schematic flow diagram of an online monitoring method for coal mine ventilators provided by the embodiments of the present application. Refer to Figure 1 , this method includes the following steps S101 - step S105.

[0041] S101: Obtain the monitoring parameters corresponding to the ventilation system in the target mine, and the monitoring parameters are the parameters for monitoring the target ventilator in the ventilation system.

[0042] In the above S101, the coal mine ventilator monitoring platform needs to monitor the ventilation system in the target mine according to the monitoring request sent by the user equipment. When monitoring the working state of the ventilator in the mine, it is necessary to clarify which ventilator in the ventilation system needs to be monitored and evaluated. Different ventilators are usually responsible for the key ventilation areas in the target mine. The ventilation system is responsible for all the ventilator systems in the target mine. The target mine is the mine for which ventilation monitoring is carried out this time, and the target ventilator is any ventilator in the ventilation system. Before obtaining the monitoring parameters of the target ventilator, it is necessary to install monitoring equipment on the target ventilator. The monitoring equipment is used to obtain the parameters of the target ventilator, and the monitoring equipment can monitor the operating state of the ventilator and the surrounding environment parameters in real time. The appropriate monitoring equipment can be selected according to the type, location, power of the target ventilator and the layout of the ventilation network. After installing the monitoring equipment at the corresponding position of the target ventilator and the monitoring equipment starts to work, the operating data of the target ventilator can be collected. The operating data includes the pipe length, diameter, bending degree and blockage condition. These data constitute the monitoring parameters of the ventilation system.

[0043] S102: Calculate the ventilation resistance coefficient according to the monitoring parameters and the target value of the target mine.

[0044] In the above S102, after the coal mine ventilator monitoring platform obtains the monitoring parameters of the target ventilator, it is also necessary to obtain the basic data of the target mine, that is, the target value. When calculating the wind resistance coefficient according to the monitoring parameters and the target value of the target mine, it specifically includes: obtaining the monitoring parameters, which include the pipe length parameter, pipe diameter parameter, pipe bending parameter and pipe blockage parameter; obtaining the target value, which includes the mine length value and the air flow velocity value; performing wind resistance calculation on the monitoring parameters and the target value to obtain the ventilation resistance coefficient.

[0045] Specifically, to obtain the pipeline length parameter, a measuring tool can be used to measure the total length of the ventilation pipeline on-site. The measuring tool includes a rangefinder or a tape measure, and then the pipeline length parameter is recorded. If there are multiple pipelines in the ventilation pipeline, the length of each section needs to be measured separately, and their connection methods need to be considered. The connection methods include series or parallel. To obtain the pipeline diameter parameter, the diameter of the pipeline is measured at multiple positions using a caliper or a measuring tool. If the pipeline diameter varies at different positions, the diameter value at each position needs to be recorded, and the impact on its ventilation resistance needs to be considered. To obtain the pipeline bending parameter, observe and record the number of bends and the bending angles in the ventilation pipeline. The bending parameter will affect the direction and speed of the air flow, and thus affect the ventilation resistance. To obtain the pipeline blockage parameter, visually inspect or use a special detection tool to detect whether there are obstacles, dust, or other substances that may cause blockage on the inner wall of the pipeline. Record the position, size, and quantity of the obstacles, which will all affect the smoothness and ventilation resistance of the ventilation pipeline. Based on the above parameters, data related to the pipeline and air flow characteristics in the target ventilator can be determined. Then obtain the basic parameters of the target mine, which can be used to calculate the ventilation resistance coefficient. Obtain the mine length value, which can be obtained from the mine design drawings or on-site measurement of the total length of the mine or the length of key areas. This value reflects the scale and ventilation requirements of the mine. Obtain the air flow velocity value. According to the safety production standards and ventilation design requirements of the mine, determine the required air flow velocity. This value is usually determined based on conditions such as the gas concentration, temperature, and humidity in the mine. Then use the monitoring parameters and target values to calculate the air resistance. The air resistance calculation formula is ; In the above formula, Q represents the air volume, that is, the air flow rate passing through a certain cross-section per unit time, R represents the air resistance value, and H represents the ventilation resistance. The air resistance value R is a comprehensive parameter that reflects the influence of various characteristics of the ventilation pipeline on the air resistance. The air resistance value can be calculated using the monitoring parameters and the target length value. The calculation of the ventilation resistance coefficient does not always use the above formula. The Darcy-Weisbach formula The Darcy-Weisbach formula is usually used to calculate the frictional resistance loss of fluid flowing in a pipeline. Therefore, the principle of the Darcy-Weisbach formula can be applied to the mine ventilation system and used to deduce the ventilation resistance coefficient. First, the general form of the Darcy-Weisbach formula is described as follows: ; In the above formula, H fIt represents the frictional resistance loss or pressure loss (unit: mH₂O or Pascal). f represents the friction coefficient, which is related to the pipe material and roughness. L represents the pipe length (unit: m), D represents the pipe diameter (unit: m), v represents the air flow velocity (unit: m / s), and g represents the acceleration due to gravity (unit: m / s²). In the mine ventilation system, the air flow in the roadway is similar to the fluid flow in the pipe. Therefore, the general form of the Darcy - Weisbach formula can be used as a reference to derive the ventilation resistance coefficient. The ventilation resistance coefficient is usually related to factors such as the geometric shape, roughness of the roadway, and the velocity of the air flow. To relate the Darcy - Weisbach formula to the ventilation resistance coefficient, the ventilation resistance coefficient can be defined as a quantity related to the friction factor. In mine ventilation, the ventilation resistance coefficient can be derived through a form similar to the Darcy - Weisbach formula: ; In the above formula, h represents the ventilation resistance (unit: Pascal), k represents the ventilation resistance coefficient, L represents the roadway length (unit: m), A represents the cross - sectional area of the roadway (unit: m²), Q is the air volume (unit: m³ / s), and A is the cross - sectional area of the roadway, not the pipe diameter. This is because mine roadways are usually rectangular or approximately rectangular in shape, rather than circular pipes. In the ventilation coefficient, the ventilation resistance coefficient is usually related to factors such as the shape, material, roughness of the pipe, and the velocity and density of the air flow. In this application, the longer the length of the target mine, the greater the ventilation resistance, and the ventilation resistance coefficient reflects the efficiency of the ventilation system in overcoming resistance.

[0046] For example, obtain the monitoring parameters of the target ventilator. Among the monitoring parameters, the total length of the ventilation pipe is 1000 m, the pipe diameter is 1 m, there are two 90 - degree bends in the pipe bending parameter, and the inner surface of the pipe is smooth. Then, based on the target value of the target mine and the parameters of the ventilation pipe, the Darcy - Weisbach formula or other applicable formulas can be used to calculate the ventilation resistance coefficient.

[0047] S103: Obtain the first gas concentration value corresponding to the target mine.

[0048] In the above S103, before the coal mine ventilation machine monitoring platform obtains the first gas concentration value of the target mine, it is necessary to set gas concentration monitoring points at key positions in the target mine, install gas concentration sensors or other special gas monitoring equipment at these monitoring points, and then read and record the gas concentration value in real - time according to the gas monitoring equipment, that is, the first gas concentration value. The first gas concentration value reflects the gas distribution in the target mine.

[0049] In addition, obtaining the first gas concentration value corresponding to the target mine specifically includes: obtaining multiple measurement positions of the target mine, where the multiple measurement positions include the working face position, the roadway position, and the ventilation opening position; installing the target measurement device at the target position, where the target position is any one of the multiple measurement positions, and the target measurement device includes a gas concentration sensor, a gas detector, a mine lamp gas monitor, and an optical methane detector; using the target measurement device to monitor the target position to obtain the first gas concentration value. Specifically, it is necessary to analyze the overall structure and layout of the target mine to understand the main areas and functions within the target mine, and then based on the structure and functions of the target mine, determine multiple measurement positions where the gas concentration needs to be monitored. The multiple measurement positions include the working face position, where the working face position refers to the coal mining face or the tunneling face, the roadway position refers to the main roadway or the branch roadway, and the ventilation opening position refers to the air inlet and the air outlet. After determining the multiple measurement positions, mark the measurement positions on the target mine map or on-site to ensure the accuracy and convenience of subsequent measurement work. Then select one of the multiple measurement positions as the current target position, and based on the actual situation of the position, select a suitable gas concentration measurement device, such as a gas concentration sensor, a gas detector, a mine lamp gas monitor, and an optical methane detector. Gas concentration sensors are one of the most commonly used devices, and they can monitor the change of gas concentration in real time and continuously. Gas concentration sensors usually work based on different principles, such as the catalytic combustion principle, the infrared absorption principle, or the electrochemical principle, and have the characteristics of high sensitivity, high stability, and fast response. The sensors can be installed at different positions in the mine and transmit data to the monitoring center through wired or wireless means. Gas detector: Portable gas detectors are usually carried by miners to detect the gas concentration at any time during the operation. These devices usually have an intuitive and easy-to-read display screen and an alarm function. When the gas concentration exceeds the safety threshold, they will emit an audible and visual alarm to remind the miners to take safety measures in a timely manner. The mine lamp gas monitor is a gas monitoring device integrated in the mine lamp. When the gas concentration in the surrounding environment of the mine lamp exceeds the warning line, the mine lamp will emit an alarm signal to remind the operators to take safety measures in a timely manner. The optical methane detector uses the optical principle to detect the methane concentration and has high precision and reliability. They are usually used for accurate measurement and calibration of the gas concentration. Ensure that the target measurement device is in good condition, accurate, and complies with relevant safety standards. Then install the selected target measurement device at the target position, and the installation process should ensure that the device is stable and reliable, and avoid being interfered by other factors.Then, in accordance with the operation instructions of the target measuring device, start the target measuring device to ensure that it is in a normal working state. According to the actual situation of the mine and the monitoring requirements, set the detection parameters of the target measuring device, and then start the monitoring function of the device to begin real-time monitoring of the gas concentration at the target location. During the monitoring process, the device will automatically record the values of the gas concentration. Analyze the data recorded by the target monitoring device to extract the first gas concentration value at the target location, and the first gas concentration value represents the gas concentration situation at the target location during the monitoring period.

[0050] S104: Determine the performance function corresponding to the target ventilator based on the target mine.

[0051] In the above S104, based on the target mine, determine the performance function corresponding to the target ventilator. Analyze the type, specifications, and previous operation data of the target ventilator to understand its performance under different conditions. Then, based on the above analysis, establish a function that can reflect the relationship between the performance of the target ventilator and parameters such as the ventilation resistance coefficient and gas concentration. This function can be obtained through experimental data or empirical formulas.

[0052] In addition, the calculation formula of the performance function may vary depending on the specific type and design of the ventilator, but it can usually be determined through experimental tests and data analysis. Generally speaking, the performance function describes the static pressure that the ventilator can provide at different air volumes. Therefore, the calculation formula needs to reflect the relationship between the air volume and the static pressure. A common method is to use polynomial regression or curve fitting to establish the performance function. Based on the data points obtained from experimental tests (i.e., the static pressure values at different air volumes), a function model can be fitted using mathematical tools or software. This function model is usually a polynomial or curve equation that can predict the corresponding static pressure value based on the input air volume value. The specific calculation formula may be as follows: ; where f() represents a functional relationship and can be expressed in polynomial or other mathematical forms. For example, ; where A, B, and C are the coefficients obtained during the fitting process, and they represent the shape and characteristics of the ventilator performance curve. By adjusting the values of these coefficients, the function model can better fit the experimental data. After obtaining the performance function, by inputting different air volume values, the static pressure value that the target ventilator can provide can be quickly obtained, thereby evaluating the performance of the ventilation system under different conditions.

[0053] S105: Input the ventilation resistance coefficient and the first gas concentration value into the performance function to obtain the current working state of the target ventilator, and the working state includes the normal state and the abnormal state.

[0054] In the above S105, after determining the performance function according to the target mine, the performance function is usually a mathematical model derived based on the design parameters, experimental data, and actual operation experience of the target ventilator. The construction process of the performance function: Since the performance function is used to predict the static pressure value, ventilation resistance coefficient, gas concentration, and other relevant parameters of the target ventilator under given conditions, such as type, specification, and rotational speed, these may be used as constants during the model construction process. Extract the static pressure value of the target ventilator and its corresponding ventilation resistance coefficient, gas concentration, etc. from the historical operation data. Then preprocess the historical operation data, clean the data, remove outliers, and standardize or normalize the parameters. Based on fluid mechanics and the principle of the ventilator, analyze the influence of the ventilation resistance coefficient and gas concentration on the static pressure of the ventilator. For example, there is a certain functional relationship between the static pressure value (P) of the target ventilator, the ventilation resistance coefficient (R), and the gas concentration (C), such as a polynomial relationship, exponential relationship, or logarithmic relationship. Then, according to the data characteristics, select an appropriate mathematical model. Use the collected data to fit the model and determine each parameter of the model. Each parameter refers to the quantification of the influence of the ventilation resistance coefficient and gas concentration on the static pressure value. Use an independent dataset to verify the accuracy of the model. Calculate the difference between the predicted value and the actual value and evaluate the performance of the model. If the model performance is not good, adjust the model structure or collect more data to improve the model. Then apply the model to new data to predict the static pressure value of the ventilator. Analyze the model output and explain the influence of the ventilation resistance coefficient and gas concentration on the static pressure value. Because the performance function can reflect the performance of the target ventilator under different conditions, including the influence of parameters such as the ventilation resistance coefficient and the first gas concentration value on the static pressure output of the target ventilator. Input the ventilation resistance coefficient and the first gas concentration value into the performance function to obtain the current working state of the target ventilator, specifically including: input the ventilation resistance coefficient and the first gas concentration value into the performance function to obtain the first static pressure value; determine whether the first static pressure value is less than or equal to the second static pressure value, and the second static pressure value is the static pressure actually provided by the target ventilator; when the first static pressure value is less than or equal to the second static pressure value, it is confirmed that the ventilation resistance of the target ventilator is in a normal state.

[0055] Specifically, the previously calculated ventilation resistance coefficient and the first gas concentration value are used as input parameters and input into the performance function. Then, according to the calculation rules of the performance function, the input parameters are calculated to obtain an output value, that is, the first static pressure value. The first static pressure value represents the static pressure value that the target ventilator should provide under the conditions of the current ventilation resistance coefficient and the first gas concentration value. Then, it is judged whether the first static pressure value is less than or equal to the second static pressure value. The second static pressure value is the actual static pressure value provided by the target ventilator, which can be directly read through the sensors or monitoring devices on the target ventilator and reflects the performance of the target ventilator during actual operation. When the first static pressure value is less than or equal to the second static pressure value, it indicates that under the conditions of the current ventilation resistance coefficient and the first gas concentration value, the actual static pressure output of the target ventilator can meet the requirements of the performance function, and the ventilation resistance is in a normal state.

[0056] Furthermore, when evaluating the working state of the target ventilator, not only the influence of the ventilation resistance coefficient and the first gas concentration value needs to be considered, but also whether the air volume meets the requirement of reducing the gas concentration needs to be considered. Before judging whether the first static pressure value is less than or equal to the second static pressure value, the method further includes: obtaining the first air volume value, which is the air volume value required for the first gas concentration value; obtaining the second air volume value corresponding to the target ventilator; judging whether the first air volume value is less than or equal to the second air volume value; if the first air volume value is less than or equal to the second air volume value, then confirm to obtain the first static pressure value. Specifically, according to the first gas concentration value and in combination with the relationship between the gas concentration and the air volume, the air volume value required at the first gas concentration value is calculated, that is, the first air volume value. The first air volume value represents the minimum air volume required to reduce the gas concentration to the safe range. To judge whether the first air volume value is less than or equal to the second air volume value, the technical document of the target ventilator can be consulted to obtain the air volume output capacity of the target ventilator under different working conditions, and then according to the current operating state and performance parameters of the target ventilator, the operating state of the target ventilator includes the rotational speed and blade angle, etc., to determine the air volume value that can be provided currently, that is, the second air volume value. The second air volume value reflects the actual ventilation capacity of the target ventilator under the current conditions. When the first air volume value is less than or equal to the second air volume value, it indicates that the target ventilator can provide enough air volume to reduce the gas concentration to the safe range under the current state. When it is confirmed that the first air volume value is less than or equal to the second air volume value, the first static pressure value can be further obtained. When the first static pressure value is less than or equal to the second static pressure value, it is confirmed that the target ventilator is currently in a normal state.

[0057] In addition, if the first air volume value is greater than the second air volume value, it indicates that the target ventilator cannot provide enough air volume to reduce the gas concentration to the safe range under the current state, that is, the target ventilator is in an abnormal state at this time.

[0058] Furthermore, when the first static pressure value is greater than the second static pressure value, the first gas concentration value is obtained; it is determined whether the first gas concentration value is greater than the second gas concentration threshold, and the second gas concentration threshold is a pre-set safe gas concentration value; if the first gas concentration value is greater than the second gas concentration threshold, it is confirmed that the target ventilator is in an abnormal state. Specifically, after obtaining the first static pressure value according to the performance function, when the first static pressure value is greater than the second static pressure value, this means that in the current working state of the ventilator, the static pressure it provides is not sufficient to overcome the ventilation resistance, that is, there may be problems with the performance of the target ventilator. Since the performance of the target ventilator may affect the gas concentration in the target mine, the first gas concentration value is obtained to confirm the current gas concentration situation. Then it is determined whether the first gas concentration value is greater than or equal to the second gas concentration threshold, and the second gas concentration threshold is a pre-set safe gas concentration value, which represents the safety upper limit of the gas concentration in the mine. The second gas concentration threshold is usually determined according to the actual situation of the target mine, gas control standards and safety regulations. When the first gas concentration value is greater than the second gas concentration threshold, it means that the gas concentration in the target mine has exceeded the safe range, and the ventilation system has not effectively controlled the gas concentration at a safe level. Based on the above judgment, it can be confirmed that the target ventilator is currently in an abnormal state. This may be due to a decrease in the performance of the ventilator, improper maintenance or other reasons. Once it is confirmed that the ventilator is in an abnormal state, corresponding measures should be taken immediately to ensure that the gas concentration in the mine can be quickly reduced to the safe range and ensure the safe production of the mine.

[0059] In a possible implementation, when the first gas concentration value is greater than the second gas concentration threshold and the target ventilator is in an abnormal state, corresponding treatment measures need to be formulated according to the severity of the gas concentration exceeding the standard to ensure the safe production of the target mine. Specifically, it includes: calculating the difference between the first gas concentration value and the second gas concentration threshold; determining the treatment measures according to the difference, and the treatment measures include the first treatment measure and the second treatment measure; when the difference is less than or equal to the preset value, it is confirmed that the first treatment measure is taken for the target ventilator, and the first treatment measure includes stopping work; when the difference is greater than the preset value, it is confirmed that the second treatment measure is taken for the target ventilator, and the second treatment measure includes evacuating the construction personnel and starting the emergency ventilation system. Specifically, obtain the first gas concentration value and the second gas concentration threshold, subtract the second gas concentration threshold from the first gas concentration value to obtain the difference between the two, and this difference represents the degree to which the current first gas concentration value exceeds the safety threshold. Then determine the treatment measures according to the difference. The treatment measures are usually formulated according to the severity of the gas concentration exceeding the standard and generally include different levels of emergency measures. In this application, two treatment measures are set, the first treatment measure and the second treatment measure. The calculated difference can be judged to determine whether the difference exceeds the preset value. The preset value is usually set according to the safety standards and historical experience of the target mine and is used to distinguish different degrees of gas concentration exceeding the standard. According to the comparison result of the difference and the preset value, determine the treatment measures to be taken. When the difference is less than or equal to the preset value, it means that although the first gas concentration value exceeds the standard, the degree of exceeding the standard is relatively light and still within the controllable range. In this case, it can be confirmed that the first treatment measure is taken for the target ventilator. The first treatment measure includes stopping work. At this time, stopping work means immediately stopping all construction operations in the area where the gas concentration exceeds the standard to ensure the safety of personnel and equipment and avoid further exacerbating the accumulation of gas concentration. At the same time, it may also be necessary to check and repair the ventilator to ensure its performance returns to normal. When the difference is greater than the preset value, it means that the current gas concentration exceeds the standard seriously, and emergency measures must be taken immediately to ensure the safety of the mine. In this case, it should be confirmed that the second treatment measure is taken for the target ventilator. The second treatment measure usually includes evacuating the construction personnel to ensure the safety of personnel; at the same time, starting the emergency ventilation system to quickly reduce the gas concentration in the mine. These measures are aimed at minimizing the safety risks brought by the gas concentration exceeding the standard. The above two treatment measures can ensure the safe production of the target mine.
