Description

Technical Field

[0001] The present application relates to the technical field of coal mine dust reduction, and in particular to a mine-used wireless spray dust reduction control method, equipment, medium and product. Background Art

[0002] Dust is a common problem in coal mining. Coal mine dust not only harms the health of miners, but also affects the safety and environmental protection level of coal mine production. Miners are exposed to dust for a long time and are prone to occupational diseases such as pneumoconiosis, which may even endanger their lives in severe cases. In addition, the accumulation of dust may also cause safety accidents such as explosions, posing a huge threat to coal mine production. Therefore, coal mine dust control is an important part of coal mine safety production and environmental protection work.

[0003] Traditional dust control methods mainly include: wet dust removal, bag dust removal, etc., but traditional dust control methods have many shortcomings. For example, wet dust removal requires a lot of water resources, and the treated wastewater is difficult to handle; although bag dust removal has a high dust removal efficiency, the equipment is complex and the maintenance cost is high, which is not suitable for the humid and dusty environment of coal mines. In recent years, with the development of science and technology, wireless spray dust reduction technology has been gradually applied to coal mine dust control, that is, the fluid is refined into mist droplets, and then the mist droplets are used to capture dust particles in the air to form particle agglomerates. The particle agglomerates are free to settle due to the increase in mass, thereby achieving the dust removal effect. However, the control method of timed spraying is often used in the relevant technology, that is, the start time, end time and duration of each cycle of the spray are pre-set, and the intelligent sensing and adjustment functions are lacking, resulting in insufficient spray volume when the dust concentration is large, thereby affecting the dust reduction effect.

[0004] Therefore, how to improve the dust reduction effect is an urgent problem to be solved by technical personnel in this field. Summary of the invention

[0023] The embodiments of the present application are further described in detail below in conjunction with the drawings in the specification.

[0024] The embodiment of the present application provides a method for controlling wireless spray dust reduction for mining, which is executed by an electronic device, which can be a server or a terminal device, wherein the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides cloud computing services. The terminal device can be a smart phone, a tablet computer, a laptop computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, which is not limited in the embodiment of the present application. Figure 1 As shown, the method includes step S101, step S102, step S103 and step S104, wherein: Step S101: Acquire coal mine production information, and analyze key dust fall information based on the coal mine production information to determine key dust fall areas and key dust fall times.

[0025] For the embodiments of the present application, coal mine production information refers to a series of comprehensive data involved in the coal mining and operation process, including but not limited to: production process details, the overall layout structure of the mine, the operation schedule of each production link, the labor intensity of each operation point, and the dust generation estimated based on these conditions and other key elements. Together, this information constitutes a comprehensive description of coal mine production activities, providing the necessary analytical basis for subsequent dust reduction management, so as to accurately identify key dust reduction areas and time periods, thereby effectively implementing dust control measures and ensuring production safety and environmental quality. It is worth noting that the coal mine production information is the planned data before the actual production of the coal mine, not the actual data during the production process.

[0026] Furthermore, key dust reduction information is analyzed based on the coal mine production information to determine key dust reduction areas and key dust reduction times, wherein key dust reduction areas are key areas with high dust concentration and wide diffusion range, which are usually located in the main operating areas of coal mines, material transfer points, poorly ventilated areas, etc., and key dust reduction times are key time periods with high dust concentration and long duration, which may include peak coal mining operations, material loading and unloading, and transfer periods, etc. Accurately identifying key dust reduction areas and key dust reduction times can not only reduce dust concentration, but also reduce resource waste in the dust process, thereby achieving precise dust reduction. The key dust reduction areas and key dust reduction times determined above may be one, two, or more, and this is no longer limited in the embodiments of the present application. There are many specific implementation methods for key dust reduction information analysis, which are no longer limited in the embodiments of the present application. In one feasible method, regional division is performed based on the coal mine layout and production process in the coal mine production information, and the corresponding local working area of ​​the coal mine is determined; key dust reduction information analysis is performed based on the working mode, work intensity and dust reduction requirements of each local working area, and the key dust reduction area and key dust reduction time are determined, among which the key dust reduction area is a key area with high dust concentration and wide diffusion range, and the key dust reduction time is a key period with high dust concentration and long duration.

[0027] Step S102: Perform timed spray planning based on key dust reduction areas and key dust reduction times, determine the spray cycle, and control the spray dust reduction device to start spraying according to the spray cycle, wherein the spray cycle includes: the start time, end time, duration and interval time corresponding to the spray.

[0028] For the embodiments of the present application, high concentrations of dust not only affect the workers' line of sight and operating efficiency, but may also cause serious accidents such as dust explosions. Therefore, timed spraying planning based on key dust reduction areas and key dust reduction times can ensure that the spray dust reduction device works when the dust concentration is highest and the diffusion range is the widest, thereby more effectively reducing the dust concentration. At the same time, timed spraying can avoid unnecessary spraying during non-critical periods, reducing resource waste and energy consumption.

[0029] Specifically, spray planning is performed based on the estimated dust generation corresponding to the matching relationship between a key dust reduction area and a key dust reduction time, and the spray start time, end time and duration corresponding to the matching relationship are determined, wherein the spray period should match the peak period of dust concentration, and the duration is determined according to the performance of the spray dust reduction device, the dust reduction effect and the operation requirements, so as to ensure the spray dust reduction effect; normally, the interval between the start time and the end time corresponding to the spray is the same as the duration, but when performing the spray dust reduction operation, if the presence of personnel or vehicles is detected in the key dust reduction area, the spray operation will be suspended, and the spray dust reduction operation will be continued after the personnel or vehicles leave. At this time, the spray dust reduction operation is no longer terminated based on the spray end time, but the duration is used to accurately determine the time to terminate the spray dust reduction operation.

[0030] In an actual production environment, there are usually multiple key dust reduction areas and multiple key dust reduction times. Therefore, there will be multiple matching relationships. The above-mentioned spray planning operation is performed for each matching relationship to obtain the spray information corresponding to each matching relationship, and the spray information corresponding to each matching relationship is combined to obtain the spray cycle, wherein the interval time in the spray cycle is the interval time between two adjacent spray plans of the same matching relationship.

[0031] Step S103: Obtain dust information and wind force information collected by the sensor network, perform emergency dust reduction analysis based on the dust information, and determine the emergency dust reduction analysis result.

[0032] For the embodiments of the present application, the dust concentration will be affected by various factors during the coal production process, and the actual dust concentration will not always be consistent with the estimated dust generation in the coal mine production information. The actual working intensity and ventilation conditions in the actual production process will cause fluctuations in the dust concentration. A fixed spray cycle alone may not be able to fully meet the actual dust reduction needs. Therefore, emergency dust reduction operations are introduced to more flexibly respond to changes in dust concentration. Through intelligent sensing and adjustment, the spray dust reduction device can be started or adjusted in time according to the actual dust concentration, ensuring that the dust concentration is quickly reduced when it exceeds the standard, thereby improving the dust reduction effect.

[0033] Specifically, in order to accurately monitor the dust and wind information in the coal mine, multiple dust sensors and wind sensors will be deployed in advance at relevant locations in the coal mine. Of course, other types of sensors can also be deployed to form a sensor network, such as infrared sensors, ultrasonic sensors, microwave radar sensors or induction coil sensors. For dust sensors, they are usually set up at coal mining faces (for example, within 10m~15m of the crushing, transfer points and return air lanes), tunneling faces (for example, within 10m~15m of the return air side of the tunneling face), and other key dust-producing locations (for example, drilling, loading and transportation areas). The installation height of dust sensors is usually consistent with the height of the workers' breathing zone, so as to more accurately reflect the dust concentration in the environment where the workers are located. For wind sensors, they are usually set up in the main ventilation lanes and key nodes (for example, key nodes such as lane intersections and branch points). Wind sensors should be installed away from obstacles and interference sources to ensure the accuracy of the measurement results.

[0034] Then, the dust information and wind force information collected by the sensor network are obtained, wherein the dust information includes: dust concentration, dust distribution information, dust type, and the wind force information includes: wind speed and wind direction. At the same time, the electronic device also pre-stores the dust concentration abnormality threshold, and compares the dust concentration and the dust concentration abnormality threshold. When the dust concentration is less than the dust concentration abnormality threshold, it indicates that the current dust concentration meets the requirements and no emergency dust reduction operation is required, and the emergency dust reduction analysis result is determined to continue monitoring; otherwise, it indicates that the current dust concentration does not meet the requirements and emergency dust reduction operations need to be performed, and the emergency dust reduction analysis result is determined to start emergency dust reduction. As for the dust concentration abnormality threshold, the dust concentration abnormality threshold is formulated with reference to local occupational health and safety regulations and relevant industry standards, and specifies the maximum allowable exposure concentration to ensure that the dust concentration in the working environment does not cause harm to the health of workers.

[0035] Step S104: When the emergency dust reduction analysis result indicates that emergency dust reduction is to be initiated, intelligent sensing adjustment analysis is performed based on the dust information and wind force information to determine the emergency spray information, and the emergency spray dust reduction device is controlled to perform emergency dust reduction operations according to the emergency spray information.

[0036] For the embodiments of the present application, when the emergency dust reduction analysis result is to continue monitoring, there is no need to perform other technical operations, and the dust information and wind information collected by the sensor network can be continuously obtained for emergency dust reduction analysis. When the emergency dust reduction analysis result is to start emergency dust reduction, intelligent sensing adjustment analysis is performed based on the dust information and wind information to determine the emergency spray information, and control the emergency spray dust reduction device to perform emergency dust reduction operations according to the emergency spray information. Through intelligent sensing adjustment analysis, the spray volume and spray direction corresponding to the emergency spray dust reduction device can be intelligently adjusted according to the actual situation of the dust information and the wind information to achieve the best dust reduction effect. At the same time, the appropriate emergency spray information can timely reduce the dust information in the air, thereby effectively reducing the impact of dust on workers' health and the production environment.

[0037] There are many specific implementation methods for intelligent sensing adjustment and analysis, which are no longer limited in the embodiments of the present application. In one feasible method, a dust reduction area is selected based on dust information to determine the emergency dust reduction area, and spray dust reduction devices are screened based on the emergency dust reduction area to determine the emergency spray dust reduction device; intelligent sensing adjustment and analysis is performed based on wind information, emergency dust reduction area and the device position corresponding to the emergency spray dust reduction device to determine the emergency spray information, wherein the emergency spray information includes: the spray amount and spray direction corresponding to each emergency spray dust reduction device.

[0038] It can be seen that in the embodiment of the present application, the key dust reduction information analysis is performed based on the coal mine production information, the key dust reduction area and the key dust reduction time are determined, and the key dust reduction area and the key dust reduction time are accurately identified, which can not only reduce the dust concentration, but also reduce the waste of resources in the dust process, thereby achieving precise dust reduction. Then, based on the key dust reduction area and the key dust reduction time, the timed spraying planning is performed, the spraying cycle is determined, and the spray dust reduction device is controlled to start spraying according to the spraying cycle. The timed spraying can avoid unnecessary spraying during non-critical periods, reducing resource waste and energy consumption. Furthermore, based on the dust information, the emergency dust reduction analysis is performed, and the emergency dust reduction analysis result is determined. When the emergency dust reduction analysis result is to start the emergency dust reduction, the intelligent sensing adjustment analysis is performed based on the dust information and the wind information, the emergency spray information is determined, and the emergency spray dust reduction device is controlled to perform the emergency dust reduction operation according to the emergency spray information. Through intelligent sensing and adjustment, the spray dust reduction device can be started or adjusted in time according to the actual dust concentration, ensuring that the dust concentration is quickly reduced when the dust concentration exceeds the standard, thereby improving the dust reduction effect.

[0039] Furthermore, in order to significantly improve the dust reduction efficiency and ensure that the spray dust reduction effect matches the actual situation and avoid waste of resources, in the embodiment of the present application, intelligent sensing adjustment analysis is performed based on dust information and wind information to determine emergency spray information, including: Based on the dust information, the dust reduction area is selected to determine the emergency dust reduction area, and the spray dust reduction device is selected based on the emergency dust reduction area to determine the emergency spray dust reduction device; Based on the wind force information, the emergency dust reduction area and the device position corresponding to the emergency spray dust reduction device, intelligent sensing adjustment analysis is performed to determine the emergency spray information, wherein the emergency spray information includes: the spray volume and spray direction corresponding to the emergency spray dust reduction device.

[0040] For the embodiments of the present application, the dust reduction efficiency can be significantly improved by accurately locating the emergency dust reduction area and executing the selection of the spray dust reduction device. At the same time, the intelligent adjustment of the spray parameters can ensure that the spray dust reduction effect matches the actual situation and avoid waste of resources.

[0041] Specifically, based on the dust concentration and dust distribution information in the dust information, the dust concentration is compared with the dust concentration abnormality threshold, and the area where the dust concentration is greater than the dust concentration abnormality threshold is selected as the emergency dust reduction area to ensure that the dust concentration in the area is effectively controlled, wherein the number of the emergency dust reduction areas can be one, two or more, and the embodiments of the present application are no longer limited. Then, according to the dust type, concentration level and dust reduction requirements of the emergency dust reduction area, a suitable type of spray dust reduction device is selected. For example, for areas with high dust concentration, a high-pressure spray pile dust reduction device can be selected; for areas with dispersed dust, a fog cannon can be selected. Then, based on the device position corresponding to the type of spray dust reduction device and the emergency dust reduction area, the device is screened to determine the emergency spray dust reduction device, wherein the emergency spray dust reduction device is a spray dust reduction device of the corresponding type whose working range covers the emergency dust reduction area.

[0042] Furthermore, based on the wind information, the emergency dust reduction area and the device position corresponding to the emergency spray dust reduction device, an intelligent sensing adjustment analysis is performed to determine the emergency spray information. In the process of executing the intelligent sensing adjustment analysis, the wind speed and wind direction factors are comprehensively considered, and the direction and amount of the spray are adjusted based on the actual situation of the wind information, so that the spray can cover the dust reduction area more accurately, ensuring that the spray effect is maximized to achieve accurate dust reduction. For the intelligent sensing adjustment analysis, the corresponding relationship between the spray amount and the dust concentration is used to match the dust information of the emergency dust reduction area with the spray amount, and the spray amount corresponding to the emergency spray dust reduction device is determined. The appropriate spray amount can reduce the waste of water resources while ensuring the dust reduction effect; at the same time, the wind speed and wind direction factors will affect the diffusion conditions of the spray. Therefore, the spray direction corresponding to the emergency spray dust reduction device is intelligently adjusted based on the wind information to ensure that the water mist can cover the emergency dust reduction area.

[0043] It can be seen that in the embodiment of the present application, the dust reduction area is selected based on the dust information to determine the emergency dust reduction area, and the spray dust reduction device is screened based on the emergency dust reduction area to determine the emergency spray dust reduction device. Then, based on the wind information, the emergency dust reduction area and the device position corresponding to the emergency spray dust reduction device, intelligent sensing adjustment analysis is performed to determine the emergency spray information. By accurately locating the emergency dust reduction area and executing the spray dust reduction device selection, the dust reduction efficiency can be significantly improved. At the same time, the intelligent adjustment of the spray parameters can ensure that the spray dust reduction effect matches the actual situation and avoid waste of resources.

[0044] Furthermore, in order to ensure the safety of personnel and equipment and avoid unnecessary waste of resources and potential safety risks, in an embodiment of the present application, the emergency spray dust suppression device is controlled to perform emergency dust suppression operations according to the emergency spray information, including: When the emergency spray dust reduction device performs a spray operation, a multi-dimensional signal collected by the sensor network is obtained in real time, and a mobile entity detection is performed based on the multi-dimensional signal and the emergency dust reduction area to determine the mobile entity detection result; When the mobile entity detection result is that there is a mobile entity intrusion, the emergency spray dust suppression device is controlled to turn off the spray until the mobile entity detection result changes to no mobile entity intrusion; Get the spray shutdown time, control the emergency spray dust suppression device to reopen the emergency dust suppression operation according to the spray shutdown time and the emergency spray information, and add the spray shutdown time to the spray time.

[0045] For the embodiment of the present application, the emergency dust reduction operation is a flexible dust reduction treatment based on the actual situation of the coal mine. Personnel, vehicles or other equipment cannot know in advance that the emergency dust reduction area will perform spray operations during this period. Therefore, there may be situations where mobile entities break into the emergency dust reduction area. However, when the emergency spray dust reduction device performs the spray operation, the spray may have an adverse effect on these mobile entities, such as obstructed vision, respiratory irritation, etc. In order to ensure the safety of personnel and equipment, it is necessary to detect the presence of mobile entities in real time and shut down the spray when necessary to avoid unnecessary waste of resources and potential safety risks.

[0046] Specifically, various types of sensors are pre-deployed in the emergency dust reduction area in the coal mine, including but not limited to: infrared sensors, ultrasonic sensors, microwave radar sensors or induction coil sensors, which are used to collect multi-dimensional signals in the emergency dust reduction area in real time. Then, mobile entity detection is performed based on the multi-dimensional signals and the emergency dust reduction area to determine the mobile entity detection results, wherein the mobile entity detection results include: mobile entity intrusion and no mobile entity intrusion. That is, a virtual boundary or threshold is set for the emergency dust reduction area, and the mobile entity is judged whether it has created the emergency dust reduction area according to the mobile entity position and speed information extracted from the multi-dimensional signal. When the mobile entity detection result is that there is a mobile entity intrusion, the emergency spray dust reduction device is controlled to turn off the spray until the mobile entity detection result changes to no mobile entity intrusion. Then, the spray closing time is obtained, and the emergency spray dust reduction device is controlled to restart the emergency dust reduction operation, that is, the spray operation is performed according to the original spray amount and spray direction, but the spray closing time needs to be added to the original spray period to ensure that the duration of the emergency dust reduction operation is consistent with the original induction adjustment analysis, so as to avoid the mobile entity intrusion affecting the effect of the emergency dust reduction operation.

[0047] It can be seen that in the embodiment of the present application, in order to ensure the safety of personnel and equipment, it is necessary to detect the presence of mobile entities in real time and shut down the spray when necessary to avoid unnecessary waste of resources and potential safety risks. Therefore, when the emergency spray dust reduction device performs the spray operation, the multi-dimensional signal collected by the sensor network is acquired in real time, and the mobile entity detection is performed based on the multi-dimensional signal and the emergency dust reduction area to determine the mobile entity detection result. When the mobile entity detection result is that there is a mobile entity intrusion, the emergency spray dust reduction device is controlled to shut down the spray until the mobile entity detection result changes to no mobile entity intrusion. Furthermore, the emergency spray dust reduction device is controlled to reopen the emergency dust reduction operation according to the spray shutdown duration and the emergency spray information.

[0048] Further, in order to improve the accuracy and reliability of dust suppression, in the embodiment of the present application, after controlling the emergency spray dust suppression device to perform the emergency dust suppression operation according to the emergency spray information, it also includes: When the emergency dust reduction operation is completed, the dust information collected by the sensor network is obtained, and the dust reduction effect is evaluated based on the dust information to determine the dust reduction effect evaluation result; When the dust reduction effect evaluation result is that the dust reduction expectation is not met, the wind force information after dust reduction collected by the sensor network is obtained, and a secondary dust reduction analysis is performed based on the dust information after dust reduction and the wind force information after dust reduction. The secondary dust reduction information is determined and sent to the mining dust reduction robot to control the mining dust reduction robot to autonomously navigate and perform the secondary dust reduction task.

[0049] For the embodiment of the present application, the emergency spray dust suppression device may be affected by various factors during the emergency dust suppression operation according to the emergency spray information, resulting in unsatisfactory dust suppression effect, such as the coverage of the spray dust suppression device, wind power adjustment, working status of the spray dust suppression device, etc. If the dust suppression effect evaluation result is that the dust suppression effect does not meet the dust suppression expectations, timely taking secondary dust suppression operations can significantly improve the dust suppression quality, ensure that the dust suppression operation achieves the expected dust suppression effect, and improve the accuracy and reliability of dust suppression.

[0050] Specifically, after the emergency dust reduction operation is completed, the sensor network is started to collect dust information after dust reduction, which includes but is not limited to: dust concentration after dust reduction and dust distribution information after dust reduction. Based on the comparison between the dust concentration after dust reduction and the dust concentration abnormality threshold, when the dust concentration after dust reduction is still greater than the dust concentration abnormality threshold, it is directly determined that the dust reduction effect evaluation result does not meet the dust reduction expectation. When the dust concentration after dust reduction is not greater than the dust concentration abnormality threshold, the dust reduction effect is analyzed and calculated based on the dust information before the emergency dust reduction operation is performed and the dust information after dust reduction, and the dust reduction percentage is determined. Then, when the dust reduction percentage reaches the expected dust reduction percentage, the dust reduction effect evaluation result is determined to have met the dust reduction expectation; otherwise, the dust reduction effect evaluation result is determined to have failed to meet the dust reduction expectation.

[0051] When the dust reduction effect evaluation result is that the dust reduction expectation is met, the remaining operations will not be performed; when the dust reduction effect evaluation result is that the dust reduction expectation is not met, the wind force information after dust reduction collected by the sensor network is obtained, and secondary dust reduction analysis is performed based on the dust information after dust reduction and the wind force information after dust reduction, and the secondary dust reduction information is determined, and the secondary dust reduction information is sent to the mining dust reduction robot to control the mining dust reduction robot to autonomously navigate and perform the secondary dust reduction task. The mining dust reduction robot is equipped with an efficient spray device and an air purification module, which can automatically perform secondary dust reduction operations after arriving at the emergency dust reduction area. At the same time, the mining dust reduction robot is also equipped with a laser radar and a visual sensor to achieve precise positioning and obstacle avoidance, ensuring free movement in a complex mine environment. For secondary dust fall analysis, dust concentration and distribution analysis is performed based on the dust information after dust fall to determine which areas have high dust concentration and which dust particle sizes are difficult to be effectively removed. Then, wind impact analysis is performed based on the wind information after dust fall to determine the impact of wind direction and wind speed on dust diffusion and sedimentation. Furthermore, based on the above two analyses, secondary dust fall information is formulated, including but not limited to: secondary dust fall target area, spray intensity, spray angle, spray frequency, spray pattern and other information.

[0052] It can be seen that in the embodiment of the present application, after the emergency dust reduction operation is completed, the dust information after dust reduction collected by the sensor network is obtained, and the dust reduction effect is evaluated based on the dust information after dust reduction to determine the dust reduction effect evaluation result. When the dust reduction effect evaluation result is that the dust reduction expectation is not met, a secondary dust reduction analysis is performed based on the dust information after dust reduction and the wind force information after dust reduction to determine the secondary dust reduction information, and the secondary dust reduction information is sent to the mining dust reduction robot to control the mining dust reduction robot to autonomously navigate and perform the secondary dust reduction task. If the dust reduction effect evaluation result is that the dust reduction expectation is not met, timely taking secondary dust reduction operations can significantly improve the dust reduction quality, ensure that the dust reduction operation achieves the expected dust reduction effect, and improve the accuracy and reliability of dust reduction.

[0053] Further, in order to improve the reliability and stability of the spray dust reduction, in the embodiment of the present application, when the dust reduction effect evaluation result is that the dust reduction expectation is not met, it also includes: Obtain the working parameters of the emergency spray dust suppression device, perform working status analysis based on the working parameters, and determine the working status of the dust suppression device; When the working state of the dust suppression device is abnormal, the emergency spray dust suppression device is marked as abnormal, and the standby spray dust suppression device is started, wherein the abnormal state is marked to facilitate maintenance personnel to repair the damaged spray dust suppression device; When the dust reduction device is in normal working condition, an intelligent condition instruction to be optimized is generated, wherein the intelligent condition instruction to be optimized is used to remind the optimization of the intelligent sensing adjustment analysis.

[0054] For the embodiments of the present application, when the dust reduction effect evaluation result is that the dust reduction expectation is not met, it is impossible to rule out whether the emergency spray dust reduction device is damaged. However, the spray dust reduction device is a key equipment in the dust reduction system, and its working state directly affects the dust reduction effect. It is necessary to promptly detect the failure of the spray dust reduction device to improve the reliability and stability of the spray dust reduction.

[0055] Specifically, the working parameters of the emergency spray dust suppression device are obtained, and the working parameters include but are not limited to: spray range, spray particle size, spray flow rate, working pressure, etc. Then, the working status analysis is performed using the normal working parameter range and working parameters of the dust suppression device. When the working parameters are all within the normal working parameter range, the working status of the dust suppression device is determined to be normal; otherwise, the working status of the dust suppression device is determined to be abnormal. Furthermore, when the working status of the dust suppression device is abnormal, the emergency spray dust suppression device is marked as an abnormal state. Marking it as an abnormal state facilitates maintenance personnel to repair the damaged spray dust suppression device, and there is no need to inspect each spray dust suppression device one by one. After that, starting the standby spray dust suppression device can quickly fill the gap in dust suppression capacity and ensure that the subsequent dust suppression effect is not affected, thereby maintaining the stability of the production environment and the health of the workers.

[0056] When the dust suppression device is in normal working condition, the dust suppression effect of the emergency dust suppression operation does not meet the expected dust suppression effect. This is not caused by a fault in the emergency spray dust suppression device, but by inaccurate intelligent sensing adjustment analysis. Therefore, an intelligent condition instruction to be optimized is generated to remind you to optimize the intelligent sensing adjustment analysis, so as to reduce the probability that the subsequent spray dust suppression effect still cannot meet the expected dust suppression effect, thereby improving the dust suppression effect.

[0057] It can be seen that in the embodiment of the present application, the working parameters of the emergency spray dust suppression device are obtained, the working state analysis is performed based on the working parameters, and the working state of the dust suppression device is determined. When the working state of the dust suppression device is abnormal, the emergency spray dust suppression device is marked as an abnormal state, and the standby spray dust suppression device is started. Timely detection of the failure of the spray dust suppression device and starting the standby spray dust suppression device improves the reliability and stability of the spray dust suppression. Furthermore, when the working state of the dust suppression device is normal, an intelligent conditional instruction to be optimized is generated to facilitate the reminder to optimize the intelligent sensing adjustment analysis, so as to reduce the probability that the subsequent spray dust suppression effect still cannot meet the dust suppression expectations, thereby improving the dust suppression effect.

[0058] Furthermore, in order to effectively reduce dust concentration and reduce environmental pollution, in an embodiment of the present application, key dust reduction information analysis is performed based on coal mine production information to determine key dust reduction areas and key dust reduction times, including: Based on the coal mine layout and production process in the coal mine production information, regional division is carried out to determine the corresponding local working area of ​​the coal mine; Based on the working mode, work intensity and dust reduction requirements of each local work area, key dust reduction information is analyzed to determine the key dust reduction areas and key dust reduction times. Among them, the key dust reduction areas are the key areas with high dust concentration and wide diffusion range, and the key dust reduction times are the key time periods with high dust concentration and long duration.

[0059] For the embodiment of the present application, the coal mine layout includes but is not limited to key information such as underground tunnels, mining working faces, ventilation systems, and transportation systems. The production process helps to clarify the execution relationship between coal mining, transportation, ventilation, drainage, and other links in the coal mine production process. Then, based on the coal mine layout and production process in the coal mine production information, regional division is performed to determine the corresponding local working area of ​​the coal mine, that is, in the process of performing regional division, regional division is performed according to the production process in the production process, so as to divide the coal mine into mining areas, transportation areas, processing areas, etc., and each area corresponds to a different production process link.

[0060] Then, based on the working mode, work intensity and dust reduction requirements of each local work area, the key dust reduction information is analyzed to determine the key dust reduction area and key dust reduction time. Among them, the key dust reduction area is the key area with high dust concentration and wide diffusion range, and the key dust reduction time is the key period with high dust concentration and long duration. The mining area is the area with the highest dust concentration and the widest diffusion range. When the key dust reduction area is the mining area, the period when the multi-purpose excavator is working is selected as the key dust reduction time. Although the amount of dust generated in the transportation area and the processing area is relatively small, the dust generated during the transportation and processing of coal still needs attention. Therefore, when the key dust reduction area is the transportation area or the processing area, the peak period of coal transportation and the operation period of processing equipment are selected as the key dust reduction time. Accurately identifying the key areas with high dust concentration and wide diffusion range, as well as the key periods with high dust concentration and long duration, provides a scientific basis for achieving precise dust reduction, and can ensure that dust reduction operations are carried out in the areas and times where dust reduction is most needed, thereby effectively reducing dust concentration and reducing environmental pollution.

[0061] It can be seen that in the embodiment of the present application, regional division is performed based on the coal mine layout and production process in the coal mine production information, and the local working area corresponding to the coal mine is determined. Then, key dust reduction information analysis is performed based on the working mode, work intensity and dust reduction requirements of each local working area to determine the key dust reduction area and key dust reduction time. Accurately identifying key areas with high dust concentration and wide diffusion range, as well as key time periods with high dust concentration and long duration, provides a scientific basis for achieving precise dust reduction, and can ensure that dust reduction operations are carried out in areas and times where dust reduction is most needed, thereby effectively reducing dust concentration and reducing environmental pollution.
