[0028] The following describes in detail embodiments of the present disclosure, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0029] The acquisition, storage, use, and processing of data in the technical solution disclosed herein are in compliance with the relevant provisions of relevant laws and regulations.

[0030] It should be noted that in the embodiments of this application, certain software, components, models and other existing solutions in the industry may be mentioned. They should be considered as exemplary. Their purpose is only to illustrate the feasibility of implementing the technical solution of this application, but it does not mean that the applicant has or will necessarily use the solution.

[0031] Figure 1 This is a schematic diagram of a method for controlling a tunneling working face according to an embodiment of the present disclosure. Figure 1 As shown, the excavation working face control method includes the following steps:

[0032] S101, obtain wind speed alarm analysis data and wind speed warning analysis data of the target excavation working face, and obtain the dynamic required air volume interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face and the cross-sectional area of ​​the excavation tunnel.

[0033] The excavation working face control method of the embodiment of the present application can be applied to the scenario of underground airflow control. The executor of the excavation working face control of the embodiment of the present application can be the excavation working face control device of the embodiment of the present application, and the excavation working face control device can be set on an electronic device.

[0034] In the disclosed embodiment, there are many methods for obtaining the wind speed alarm analysis data and wind speed warning analysis data of the target excavation working face, and obtaining the dynamic required air volume interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face and the cross-sectional area of ​​the excavation tunnel of the target excavation working face, and no limitation is made here.

[0035] In one possible implementation, data can be acquired through a sensor network distributed at specific locations underground. This sensor network collects and detects real-time data from the underground mine. Based on this real-time data, it processes and generates wind speed alarm and warning analysis data, as well as dynamic required air volume intervals, real-time air volume at the tunneling face, real-time wind speed at the tunneling face, and the cross-sectional area of ​​the tunneling tunnel. The sensors can be of various types, without limitation. For example, they can include air volume sensors, wind speed sensors, and optical sensors.

[0036] In another possible implementation method, a dynamic model of the underground can be established. According to the specific conditions of the excavation working face (such as length, width, height), the type of operation and the amount of dust generated, a mathematical model can be established to estimate the wind speed alarm analysis data and the wind speed warning analysis data, as well as the dynamic air volume required interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face and the cross-sectional area of ​​the excavation tunnel.

[0037] In another possible implementation, a trained neural network model can be used to predict future data for the target tunneling face. This can generate wind speed alarm and warning analysis data, as well as estimate the dynamic required air volume range, real-time air volume, real-time wind speed, and cross-sectional area of ​​the tunneling face.

[0038] S102, based on the wind speed alarm analysis data and the wind speed warning analysis data, the local ventilation fan target control instructions, the wind window adjustment control instructions and the main ventilation fan control instructions are generated, and the air volume adjustment target value of the target excavation working face is calculated based on the dynamic air volume required interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face and the cross-sectional area of ​​the excavation tunnel.

[0039] It's important to note that target air volume at the tunneling face is a key parameter for ensuring a safe working environment, improving work efficiency, and protecting worker health. These target values ​​are typically determined based on a variety of factors, including but not limited to legal and regulatory requirements, mine ventilation design standards, actual working conditions, and safety considerations.

[0040] It's important to note that local ventilators (LVs) play a crucial role in mine excavation working faces, primarily providing fresh air, diluting and exhausting harmful gases, and controlling dust. LVs are regulated to ensure sufficient airflow at the working face, and are dynamically adjusted based on actual conditions to meet safety and production requirements.

[0041] Air dampers (also known as adjustable dampers or ventilation louvers) are crucial components of mine ventilation systems, precisely controlling air flow through the roadway. By adjusting the opening size to vary wind resistance, they effectively control air volume and direction. This is crucial for ensuring adequate ventilation in all areas of the mine, particularly at the tunneling face, while also controlling hazardous gas concentrations and reducing dust levels.

[0042] The main fan is the core equipment in the mine ventilation system. It is responsible for providing fresh air to the entire mine and exhausting harmful gases and dust to ensure the safety and health of the underground working environment.

[0043] Local ventilators are primarily used to meet the ventilation needs of local areas or specific work sites and offer a high degree of flexibility. Adjustable dampers are used to fine-tune air volume distribution between different areas within the mine, ensuring a balanced and efficient ventilation network. Main ventilators are the foundation of the entire mine ventilation system, responsible for overall ventilation and ensuring the safety and efficiency of the entire mine. The three types of equipment differ in their airflow control methods and scenarios, and in terms of control costs, local ventilators are less expensive than adjustable dampers, which in turn are less expensive than main ventilators.

[0044] S103, performing airflow control on the target excavation working face based on the local ventilator target control instruction, the wind window adjustment control instruction, the main ventilator control instruction and the air volume adjustment target value.

[0045] It should be noted that the ultimate goal of airflow control is to make the airflow underground reach the target value of air volume adjustment. Due to the complex working conditions underground, not all of these three adjustment instructions need to be put into underground airflow control. Perhaps only one or two of them are needed to meet the preset requirements. Due to the cost of control, the local fan is lower than the adjustment window, and the adjustment window is lower than the main fan. In consideration of the cost of control,

[0046] Therefore, control rules can be used to adjust the air volume target value and select one or more control commands from the local fan target control command, the damper control command, and the main fan control command to control airflow. This simplifies the airflow control process and, by combining the three airflow control methods, achieves better underground airflow control results.

[0047] It should be noted that the control rules are designed in advance and can be changed according to actual design needs. No restrictions are made here.

[0048] In the disclosed embodiment, wind speed alarm analysis data and wind speed warning analysis data of the target excavation working face are first obtained, and the dynamic required air volume interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face, and the cross-sectional area of ​​the excavation tunnel of the target excavation working face are obtained. Then, based on the wind speed alarm analysis data and the wind speed warning analysis data, a local fan target control instruction, an adjustment window control instruction, and a main fan control instruction are generated. The air volume adjustment target value of the target excavation working face is calculated based on the dynamic required air volume interval value of the excavation working face, the real-time air volume of the excavation working face, the real-time wind speed of the excavation working face, and the cross-sectional area of ​​the excavation tunnel. Finally, airflow control is performed on the target excavation working face based on the local fan target control instruction, the adjustment window control instruction, the main fan control instruction, and the air volume adjustment target value. Thus, according to the air volume adjustment target value, one or more control instructions are selected from the local fan target control instruction, the adjustment window control instruction, and the main fan control instruction to perform airflow control. This can simplify the airflow control process, and by combining the three airflow control methods, better underground airflow control effects can be achieved.

[0049] In the above embodiment, the airflow control of the target excavation working face is performed based on the local fan target control instruction, the wind window control instruction, the main fan control instruction and the air volume adjustment target value, and the airflow control can also be controlled by Figure 2 Explaining further, the method includes:

[0050] S201, calculate the first air volume after the local fan target control instruction controls the airflow of the target excavation working face, and calculate the second air volume after the local fan target control instruction and the wind window adjustment control instruction controls the airflow of the target excavation working face, and calculate the third air volume after the local fan target control instruction, the wind window adjustment control instruction and the main fan control instruction control the airflow of the target excavation working face.

[0051] S202 : In response to the first air volume being greater than or equal to the air volume adjustment target value, airflow control is performed on the target excavation working face based on the local ventilator target control instruction.

[0052] The first air volume is greater than or equal to the air volume adjustment target value. At this time, it can be considered that the local ventilation fan can independently complete the airflow control to the air volume adjustment target value.

[0053] S203, in response to the first air volume being less than the air volume adjustment target value and the second air volume being greater than or equal to the air volume adjustment target value, airflow control is performed on the target excavation working face based on the local ventilator target control instruction and the wind window adjustment control instruction.

[0054] The first air volume is less than the air volume adjustment target value, and the second air volume is greater than or equal to the air volume adjustment target value. At this time, it can be considered that the local ventilation fan cannot physically complete the airflow control to the air volume adjustment target value, and needs to cooperate with the adjustable air window.

[0055] S203, in response to the first air volume being less than the air volume adjustment target value, the second air volume being less than the air volume adjustment target value, and the third air volume being greater than or equal to the air volume adjustment target value, the airflow is controlled on the target excavation working face based on the local ventilation fan target control instruction, the adjustment window control instruction, and the main ventilation fan control instruction.

[0056] The first air volume is less than the air volume adjustment target value, and the second air volume is less than the air volume adjustment target value, and the third air volume is greater than or equal to the air volume adjustment target value. At this time, it can be considered that the three devices of local ventilation fan, adjustable air window and main ventilation fan need to work together.

[0057] In the embodiment of the present disclosure, the first air volume after the local fan target control instruction performs airflow control on the target excavation working face is first calculated, as well as the second air volume after the local fan target control instruction and the adjusting window control instruction perform airflow control on the target excavation working face, and the third air volume after the local fan target control instruction, the adjusting window control instruction and the main fan control instruction perform airflow control on the target excavation working face is calculated. Then, in response to the first air volume being greater than or equal to the air volume adjustment target value, the airflow control of the target excavation working face is performed based on the local fan target control instruction, or in response to the first air volume being less than the air volume adjustment target value and the second air volume being greater than or equal to the air volume adjustment target value, the airflow control of the target excavation working face is performed based on the local fan target control instruction and the adjusting window control instruction, or in response to the first air volume being less than the air volume adjustment target value and the second air volume being less than the air volume adjustment target value and the third air volume being greater than or equal to the air volume adjustment target value, the airflow control of the target excavation working face is performed based on the local fan target control instruction, the adjusting window control instruction and the main fan control instruction. Therefore, by calculating the air volume values ​​achievable by the three control instructions and comparing them with the air volume adjustment target values, the equipment that needs to be invested in airflow control can be accurately determined, reducing control costs and improving control efficiency.

[0058] In the above embodiment, wind speed warning analysis data can be obtained by Figure 3 Explaining further, the method includes:

[0059] S301, obtaining sensor data of the target excavation working face.

[0060] S302: Clean the sensor collected data, and perform early warning analysis on the cleaned sensor collected data to obtain wind speed early warning analysis data.

[0061] It should be noted that data cleaning can include many aspects, which are not limited here. For example, data cleaning can include missing value processing, noisy data processing, data standardization / normalization, etc.

[0062] In one possible implementation, the data collected by the cleaned sensor is processed to obtain a target air leakage rate of the target excavation working face. In response to the target air leakage rate being greater than an air leakage rate threshold, the target excavation working face is subjected to air duct leakage treatment.

[0063] It should be noted that the air leakage rate threshold is the critical value for determining that the current air leakage state is a fault. The air leakage rate threshold is designed in advance and can be changed according to actual design requirements or the actual working conditions of the target excavation working face.

[0064] In the above embodiment, wind speed alarm analysis data can be obtained by Figure 4Explaining further, the method includes:

[0065] S401, obtaining disaster or occupational health event data of a target excavation working face.

[0066] After cleaning the tunnel, the airflow from the tunnel's headwind duct flows from the tunnel's head toward the tunnel face entrance. If a disaster or occupational health incident occurs within the tunnel face, emergency ventilation is required to dilute toxic and hazardous gases. To achieve this, five relevant process steps are involved: analysis of tunnel face air volume and velocity alarms, decision-making on an emergency air volume control plan, approval of the emergency air volume control plan, remote and automatic execution of the emergency air volume control plan, and evaluation of the effectiveness of the emergency air volume control plan.

[0067] It should be noted that disaster or occupational health incident data may include multiple types, without any limitation here. For example, it may include abnormal gas outburst (concentration value), abnormal carbon dioxide outburst (concentration value); obtain sudden occupational health and hygiene incidents from the data center: dust concentration exceeding the limit (concentration value), vehicle exhaust exceeding the limit (concentration value) information, etc.; real-time wind volume and wind speed data of the excavation working face.

[0068] S402: Generate wind speed alarm analysis data based on disaster or occupational health event data.

[0069] In the embodiments of the present disclosure, before generating wind speed alarm analysis data based on disaster or occupational health event data, the disaster or occupational health event data may also be preprocessed. There may be many ways to do this preprocessing, which are not limited here. For details, please refer to the data cleaning process in the above embodiments.

[0070] In an embodiment of the present disclosure, wind speed alarm analysis data is generated based on disaster or occupational health event data. The location of the event and the required air volume can be first determined based on the disaster or occupational health event data, and then the wind speed alarm analysis data is generated based on the location of the event and the required air volume.

[0071] In one possible implementation method, the method in the embodiment of the present disclosure can also first obtain the wind window status data of the target excavation working face, then clean the wind window status data, and then perform wind window self-inspection and / or fault diagnosis on the cleaned wind window status data, and finally perform fault processing on the wind window of the target excavation working face based on the self-inspection results and / or diagnosis results.

[0072] In one possible implementation method, the method in the embodiment of the present disclosure also first obtains the main ventilation fan monitoring data of the target excavation working face, then cleans the main ventilation fan monitoring data, and then performs wind window self-inspection and / or fault diagnosis on the cleaned main ventilation fan monitoring data, and finally performs fault processing on the main ventilation fan of the target excavation working face based on the self-inspection results and / or diagnosis results.
