[0030] Example 1

[0031] Figure 1 This is a flowchart of a safety treatment method for underground coal mines provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of graded early warning of methane concentration in underground coal mines. The method can be executed by an underground safety treatment device, which can be implemented in hardware and / or software. This underground safety treatment device can be configured in the electronic device provided in this embodiment of the invention. The electronic device can be a server, computer, or mobile terminal, such as a mobile phone or tablet computer. Figure 1 As shown, the method includes:

[0032] S110. Obtain gas concentration data for the work area.

[0033] The work area refers to the area where coal mining takes place underground. Underground coal mines comprise multiple work areas, each with a unique identifier. This unique identifier allows for identification of the corresponding work area. Methane gas is a harmful gas present in underground coal mines, primarily composed of methane. Methane concentration data is the percentage of methane volume per unit volume of air, typically expressed as a percentage (%). Methane concentration data can be obtained by measuring sensors deployed in the work area, including but not limited to infrared absorption sensors. Methane concentration data can also be retrieved from a methane concentration database, which stores methane concentration data for multiple work areas. Matching the unique identifier of each work area in the database yields the corresponding methane concentration data. Obtaining methane concentration data from the work areas provides a data foundation for subsequent analysis and processing.

[0034] S120. Determine gas concentration evaluation data based on gas concentration data. The gas concentration evaluation data includes at least one of the following: gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and gas concentration data within a second duration and gas concentration decrease rate data within the second duration when the gas concentration data is greater than a preset safety value.

[0035] Among them, the gas concentration evaluation data is used to assess the gas safety status within the work area. The gas concentration evaluation data can be calculated from the gas concentration data. The gas concentration evaluation data may include one of the following: gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and gas concentration decrease rate data within a second duration when the gas concentration data exceeds a preset safety value; or two of the following: gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and gas concentration decrease rate data within a second duration when the gas concentration data exceeds a preset safety value; or gas concentration evaluation data may also include gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and gas concentration decrease rate data within a second duration when the gas concentration data exceeds a preset safety value.

[0036] The gas concentration fluctuation data represents the range of gas concentration changes within a first duration. The first duration can be set as needed, for example, it can be 1 hour or 2 hours; there is no limitation here. The gas concentration fluctuation data can be obtained by calculating the difference between the maximum and minimum values ​​of the gas concentration data within the first duration. The gas concentration growth rate data represents how quickly the gas concentration data increases over time within a preset duration. The preset duration can be set as needed, for example, it can be set to 1 minute or 5 minutes; there is no limitation here. The gas concentration growth rate data is obtained by calculating the difference between the gas concentration data at the end and the beginning of the preset duration, and then calculating the ratio of this difference to the preset duration. The gas concentration decrease rate data represents how quickly the gas concentration data decreases within a second duration. The preset safety value can be set as needed, for example, it can be set to 1.0%; there is no limitation here. The second duration can be obtained by statistically analyzing the duration during which the gas concentration data is greater than the preset safety value. Calculate the difference between the gas concentration data at the end and the beginning of the second duration, and calculate the ratio of the difference to the second duration to obtain the gas concentration decrease rate data.

[0037] Specifically, by calculating the difference between the maximum and minimum values ​​of the gas concentration data within the first duration, gas concentration fluctuation data is obtained; by calculating the difference between the gas concentration data at the end and the beginning of the preset duration, and then calculating the ratio of this difference to the preset duration, gas concentration growth rate data is obtained; the duration for which the gas concentration data exceeds the preset safety value is recorded, resulting in the second duration; by calculating the difference between the gas concentration data at the end and the beginning of the second duration, and then calculating the ratio of this difference to the second duration, gas concentration decrease rate data is obtained. This process achieves accurate determination of gas concentration evaluation data, providing accurate and comprehensive data support for subsequent analysis.

[0038] S130. Determine the gas risk type based on gas concentration assessment data. The gas risk type includes at least one of illegal mining, gas emission, and gas outburst.

[0039] Among them, gas risk type characterizes the gas risk present in the working area. Gas risk type can include at least one of illegal mining, gas emission, and gas outburst. Gas risk type can be determined based on gas concentration assessment data. For example, a mapping relationship between gas concentration assessment data and gas risk type can be pre-established, and the gas risk type can be obtained by matching the gas concentration assessment data in the mapping relationship.

[0040] Specifically, by pre-setting the mapping relationship between gas concentration evaluation data and gas risk types, the gas risk type is obtained by matching the gas concentration evaluation data in the mapping relationship, thus realizing the classification of gas risk and providing accurate data support for subsequent safety decisions.

[0041] Optionally, the method further includes: generating a warning message based on the gas risk type; sending the warning message to the target terminal and displaying the warning message, wherein the target terminal is deployed in the work area.

[0042] The notification information is used to indicate the type of gas risk in the work area. The notification information can include various forms, such as at least one of text, light, and sound information. The target terminal is a device that receives and displays the type of gas risk in the work area. The target terminal can be deployed within the work area, and different types of target terminals can be deployed in different work areas. Optionally, the target terminal includes at least one of a notification light, a display screen, and a voice player. Optionally, different target terminals correspond to different types of notification information. When the target terminal includes a notification light, the corresponding notification information type is light information; when the target terminal includes a display screen, the corresponding notification information type is text information; when the target terminal includes a voice player, the corresponding notification information type is sound information.

[0043] Optionally, the content of the warning message varies depending on the type of gas risk. Taking a target terminal including a display screen as an example: when the gas risk type is illegal mining, the warning message can be the text "The gas risk type in this work area is illegal mining"; when the gas risk type is gas outburst, the warning message can be the text "The gas risk type in this work area is gas outburst"; and when the gas risk type is gas outburst, the warning message can be the text "The gas risk type in this work area is gas outburst". Taking a target terminal including an indicator light as an example: when the gas risk type is illegal mining, the warning message can be that the indicator light is blue and flashes at a preset frequency; when the gas risk type is gas outburst, the warning message can be that the indicator light is yellow and flashes at a preset frequency; and when the gas risk type is gas outburst, the warning message can be that the indicator light is red and flashes at a preset frequency. Taking a target terminal including a voice player as an example, when the gas risk type is illegal mining, the prompt message can be an audio message stating "The gas risk type in this work area is illegal mining"; when the gas risk type is gas outburst, the prompt message can be an audio message stating "The gas risk type in this work area is gas outburst"; and when the gas risk type is gas outburst, the prompt message can be an audio message stating "The gas risk type in this work area is gas outburst".

[0044] S140. Provide safety warnings for the detected types of gas risks.

[0045] The safety warning mechanism involves alerting workers in the work area via a target terminal, indicating the corresponding gas risk type for that area. Optionally, the safety warning may include at least one of flashing lights, screen display, or voice announcement. For example, a safety warning can be issued by displaying the gas risk type of the work area on a light-emitting diode (LED) screen, by flashing LEDs of different colors, or by announcing the gas risk type of the work area via voice announcement.

[0046] Specifically, safety warnings can be issued by displaying the gas risk type of the work area on an LED screen, by flashing LEDs of different colors, or by broadcasting the gas risk type of the work area via voice. These different forms of safety warnings provide a basis for personnel in the work area to make decisions and help improve safety in underground coal mines.

[0047] The technical solution of this embodiment obtains gas concentration data of the working area, providing a data foundation for subsequent analysis and processing; based on the gas concentration data, it determines gas concentration evaluation data, which includes gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and at least one of a second duration where the gas concentration data is greater than a preset safety value and a gas concentration decrease rate data within the second duration. This achieves accurate determination of gas concentration evaluation data, providing accurate and comprehensive data support for subsequent analysis; based on the gas concentration evaluation data, it determines gas risk types, which include at least one of illegal mining, gas emission, and gas outburst, achieving accurate classification of gas risks and providing accurate data support for subsequent safety decisions; and it provides safety warnings for the detected gas risk types, enabling safety warnings for different gas risk types, which is beneficial to improving underground safety in coal mines.

[0048] Example 2

[0049] Figure 2 This is a flowchart of a safety handling method in underground coal mines according to Embodiment 2 of the present invention. This embodiment is a refinement of the above embodiments, and based on the foregoing embodiments, it provides a detailed explanation of determining the gas risk type based on gas concentration evaluation data. For specific implementation details, please refer to the technical solution of this embodiment. Technical terms that are the same as or corresponding to those in the above embodiments will not be repeated here. Figure 2 As shown, the method includes:

[0050] S210. Obtain gas concentration data for the work area.

[0051] S220. If the gas concentration fluctuation data is less than or equal to the preset fluctuation range within the first duration, the gas risk type is determined to be illegal mining; if the gas concentration growth rate data is greater than or equal to the first preset threshold within the preset duration, the gas risk type is determined to be gas outburst; if the gas concentration data is greater than the preset safety value for a second duration that is greater than or equal to the preset duration, and the gas concentration decrease rate data is less than the second preset threshold within the second duration, the gas risk type is determined to be gas outburst.

[0052] S230. If the gas concentration fluctuation data is less than or equal to the preset fluctuation range within the first duration, the gas risk type is determined to be illegal mining; if the gas concentration growth rate data is greater than or equal to the first preset threshold within the preset duration, the gas risk type is determined to be gas outburst; if the gas concentration data is greater than the preset safety value for a second duration that is greater than or equal to the preset duration, and the gas concentration decrease rate data is less than the second preset threshold within the second duration, the gas risk type is determined to be gas outburst.

[0053] The preset fluctuation range refers to the pre-defined range of gas concentration data fluctuation. When the gas concentration fluctuation data within the first duration is less than or equal to the preset fluctuation range, the gas concentration data fluctuation is small, indicating a possibility of artificial control over the gas concentration data, meaning there is a risk of illegal mining in the operating area. For example, if the preset fluctuation range is 0.1%, the first duration is 2 hours, and the gas concentration fluctuation data is 0.08%, then 0.08% < 0.1%, and the gas risk type for this operating area is illegal mining.

[0054] The first preset threshold is a safe growth threshold for the rate of increase of gas concentration in the work area, determined based on historical gas concentration data. When the rate of increase of gas concentration within a preset time period is greater than or equal to the first preset threshold, it indicates that the rate of increase of gas concentration in the work area exceeds the safe growth threshold within the preset time period, posing a risk of gas outburst. For example, if the first preset threshold is 0.5% / min and the preset time period is 1 minute, and within the preset time period, the gas concentration increases from 0.2% to 1%, the rate of increase is 0.8% / min. Since 0.8% / min > 0.5% / min, the gas risk type for this work area is gas outburst.

[0055] The second preset threshold is a safe threshold for the rate of decrease of gas concentration in the work area, determined based on historical gas concentration data. If the second duration of the gas concentration data exceeding the preset safe value is greater than or equal to the preset duration, and the rate of decrease of gas concentration within the second duration is less than the second preset threshold, it indicates that the rate of decrease of gas concentration in the work area exceeds the safe threshold within the second duration, posing a risk of gas outburst. For example, if the second preset threshold is 1.0% / min, the preset duration is 30 minutes, the preset safe value is 1.0%, and the second duration is 30 minutes, and the gas concentration data remains at 1.5% for 40 minutes without a decreasing trend within the second duration, then because the second duration is greater than the preset duration, the gas concentration data is greater than the second preset threshold, and the gas concentration data shows no decreasing trend within the second duration, the gas risk type for the work area is gas outburst.

[0056] Specifically, if the gas concentration fluctuation data is less than or equal to a preset fluctuation range within the first duration, the gas risk type is determined to be illegal mining; if the gas concentration growth rate data is greater than or equal to a first preset threshold within the preset duration, the gas risk type is determined to be gas outburst; if the gas concentration data is greater than a preset safety value for a second duration that is greater than or equal to a preset duration, and the gas concentration decrease rate data is less than a second preset threshold within the second duration, the gas risk type is determined to be gas outburst. This achieves accurate classification of gas risk types and provides precise data support for subsequent safety decisions.

[0057] Optionally, the method further includes: determining the error data of the sensors in the working area based on the gas concentration data; and determining a preset fluctuation range based on the error data of the sensors in the working area.

[0058] Error data includes, but is not limited to, drift error. For example, based on gas concentration data, determine the gas concentration data with a fluctuation range less than or equal to a preset fluctuation range within a continuous time period and the corresponding acquisition time. Based on the acquisition time, determine the gas concentration data corresponding to the start and end times of the acquisition time. Calculate the difference between the gas concentration data corresponding to the start and end times of the acquisition time, and use this difference as the preset fluctuation range. This reduces sensor measurement error and thus helps improve the accuracy of gas concentration data.

[0059] To ensure safety in underground coal mines, appropriate safety procedures must be implemented when a gas risk is detected in the work area.

[0060] Optionally, the method may further include: performing safety operations corresponding to the gas risk type based on the gas risk type.

[0061] Different types of gas risks correspond to different safe operating procedures. For example, a mapping table between gas risk types and safe operating procedures is pre-set. The detected gas risk type is matched against the mapping table to obtain the corresponding safe operating procedure, and the corresponding safe operating procedure is executed, which helps to improve the safety of the work area.

[0062] Optionally, safety operations corresponding to the gas risk type include: when the gas risk type is illegal mining, safety operations include stopping the power supply to the mining equipment in the illegal mining area and marking the illegal behavior.

[0063] Specifically, when the gas risk type is illegal mining, it indicates that there is illegal mining in the work area. To reduce losses caused by illegal mining in coal mines, power supply to the mining equipment can be stopped, and the work area can be marked with signs indicating the illegal activities, providing a basis for subsequent accountability investigations.

[0064] Optionally, the safety operations corresponding to the gas risk type include: when the gas risk type is gas outburst, the safety operations include starting the backup fan to increase ventilation and the sensors in the work area to trigger audible and visual alarms, the sensors being sensors that collect gas concentration data.

[0065] Specifically, a main ventilation fan and a backup ventilation fan are deployed within the work area. The main ventilation fan is always operational to prevent localized methane accumulation in the work area, which could affect the accuracy of methane concentration data. When the methane risk type is methane outburst, the backup ventilation fan is activated to pressurize and ventilate the area, expelling the methane from the mine and ensuring that the methane concentration data within the work area remains within safe thresholds. The sensors are equipped with buzzers and warning lights. When a methane risk type of gas outburst is detected, the sensor triggers an audible and visual alarm; the warning light flashes and the buzzer sounds, alerting personnel in the work area that the methane risk type in that area is a methane outburst.

[0066] Optionally, the safety operations corresponding to the gas risk type include: when the gas risk type is a gas outburst, the safety operations include stopping the power supply to all work areas, sending the location information of the work area corresponding to the gas outburst, and initiating a safe evacuation strategy.

[0067] The location information includes the spatial coordinates of the work area corresponding to the gas outburst risk type. This information is used to accurately locate the work area corresponding to the gas outburst, providing a spatial basis for personnel evacuation and risk management. Safe evacuation strategies include, but are not limited to, safe evacuation routes, safe evacuation exits, and safe evacuation endpoints.

[0068] Specifically, when the gas risk type is gas outburst, it indicates that there is a significant gas outburst in the work area. To prevent a gas explosion caused by excessively high gas concentrations, it is necessary to shut off power to the entire work area. The location information of the gas outburst area should be sent to the monitoring system to provide precise location information for emergency command. Simultaneously, a safe evacuation strategy should be initiated to evacuate all personnel from the coal mine, which will help reduce casualties caused by a gas explosion.

[0069] S240. Provide safety warnings for the types of gas risks detected.

[0070] For example, see Figure 3 , Figure 3 This is a flowchart of a safety handling method for underground coal mines provided by an embodiment of the present invention. The method includes the following steps:

[0071] (1) Configure alarm conditions for all sensors and obtain detection data from all sensors.

[0072] (2) Determine methane level: Determine if the methane level has remained unchanged for an extended period, if the methane level has risen rapidly, and if the methane level has triggered an alarm. If the methane level remains unchanged for an extended period, an operation violation is detected. If the methane level rises rapidly, a methane outburst warning is triggered. When the methane level triggers an alarm, the alarm duration is determined. If the alarm duration meets a preset condition, a methane outburst alarm is triggered.

[0073] (3) Perform corresponding safety operations based on different types of risks. For violations, the corresponding safety operations include triggering LED and broadcast alerts. For methane emission warnings, the corresponding safety operations include starting backup fans and triggering LED and broadcast alerts. For methane overload alarms, the corresponding safety operations include triggering power outages in the affected area and triggering LED and broadcast alerts.

[0074] The technical solution of this embodiment obtains gas concentration data of the working area, providing a data foundation for subsequent analysis and processing; based on the gas concentration data, it determines gas concentration evaluation data, which includes gas concentration fluctuation data within a first duration, gas concentration growth rate data within a preset duration, and at least one of a second duration where the gas concentration data is greater than a preset safety value and a gas concentration decrease rate data within the second duration. This achieves accurate determination of gas concentration evaluation data, providing accurate and comprehensive data support for subsequent analysis; when the gas concentration fluctuation data within the first duration is less than or equal to a preset fluctuation range, the gas wind is determined. The risk type is illegal mining; if the rate of increase in gas concentration within a preset time period is greater than or equal to the first preset threshold, the gas risk type is determined to be gas outburst; if the second duration of the gas concentration data being greater than the preset safety value is greater than or equal to the preset duration, and the rate of decrease in gas concentration within the second duration is less than the second preset threshold, the gas risk type is determined to be gas outburst. This achieves accurate classification of gas risks and provides precise data support for subsequent safety decisions. Safety warnings are issued for the detected gas risk types, enabling safety warnings for different gas risk types, which is conducive to improving underground safety in coal mines and reducing losses.
