In the embodiments of the present disclosure, these operations or steps can be performed in series; these operations or steps can also be performed in parallel; or some of these operations or steps can be performed.

[0029] First, the application scenarios of the present disclosure are described.

[0030] During the coal mining process, problems such as excessive gas, low oxygen and high nitrogen appear in the return air corners of the coal mining face, which is a difficult problem that the mine production process has always faced. Excessive gas can easily cause gas explosions, and working in a low-oxygen environment is very prone to hypoxia and suffocation, which seriously threatens the lives of workers and affects the safe production of mines.

[0031] The problems of excessive gas and insufficient oxygen concentration in the return air corners and between the return air side supports of the coal mining working face in coal mines have seriously affected the normal production work of the mine and threatened the safety of underground workers. Gas and low-oxygen gases surge to the upper corners, and their source is generally the goaf. Due to the combined influence of the ground temperature and air pressure changes, the pressure difference between the goaf and the working face changes greatly. Due to the influence of the pressure difference, the gas and low-oxygen gases that have accumulated in the goaf surge from the goaf to the corners of the working face and between the return air side supports. When the air pressure in the goaf is higher than the working face air pressure by a certain value, the amount of gas and low-oxygen gases that surge out increases, and at this time the ventilation volume of the working face is not enough to dilute the gas and low-oxygen gases in a short time. As time goes by, the gas and low-oxygen gases in the return air corners and between the supports of the working face accumulate and increase, and spread to the surroundings, and eventually the gas exceeds the limit and low oxygen occurs between the return air side supports of the return air corners of the working face. In this process, there are many related factors that affect the pressure difference between the goaf and the working face. Combined with the study of the gas migration and accumulation rules in the return air corner of the working face, it is concluded that the formation of an air leakage channel through the well and the increased air leakage between the goaf and the working face are the main causes of the hypoxia phenomenon; the generation and influx of hypoxic gas and the ventilation method of the working face are secondary causes of the hypoxia phenomenon.

[0032] It is understandable that atmospheric pressure is mainly formed by air gravity. The main factors affecting atmospheric pressure are altitude and temperature. The higher the altitude, the lower the atmospheric pressure. At the same altitude, the higher the temperature, the smaller the air density, the lower the humidity, and the lower the air pressure; the lower the temperature, the higher the air pressure. The ground temperature and air pressure change, and the pressure is transmitted through the wellbore, causing the underground air pressure to change synchronously. This change leads to unstable air pressure at the coal mining face. Since the goaf is a semi-enclosed space, when the ground temperature rises and the air pressure decreases, the air pressure in the working space of the underground working face is in the process of decreasing, breaking the original air pressure balance between the goaf and the working face. The gas (hypoxia) gas in the goaf gushes out from the downwind side of the working face (between the bracket and the return air corner). This is the release process of gas (hypoxia) gas in the goaf; when the ground temperature decreases and the air pressure increases, the air pressure in the working space of the underground working face is in the process of increasing, and the gas from the working face is replenished to the goaf, forming a high-concentration gas (hypoxia) space area. This is the gas (hypoxia) accumulation process in the goaf. This cyclical process creates a "breathing" effect in the goaf - the ground heating process is "exhalation" and the cooling process is "inhalation", leading to the abnormal outflow of gas (low oxygen).

[0033] For example, from a one-day perspective, due to the temperature changes in the morning and evening every day, the air pressure in the working space of the working face is also constantly changing, resulting in uneven outflow of low-oxygen gas. Generally, from 20:00 the previous day to 7:00 to 9:00 the next morning, the ground temperature gradually decreases and the air pressure gradually increases. The goaf is in the period of gas (low oxygen) gas accumulation, so the oxygen concentration in the return air corner and return air lane is the highest. From morning to 14:00 to 16:00 in the afternoon, the ground temperature gradually rises and the air pressure gradually decreases, breaking the original air pressure balance, and the low-oxygen gas in the goaf abnormally gushes out, and the cycle continues. For example, at 8 a.m. on January 23, the temperature dropped to -23°C, the ground air pressure rose to 94.194 KPa at 9 a.m., the working face air pressure rose to 92.918 KPa, and the oxygen concentration in the return air corner was as high as 19.4%; as the temperature rose to -4.6°C, the ground air pressure dropped to 93.765 KPa at 16:00, the working face air pressure dropped to 92.524 KPa, and the oxygen concentration in the return air corner dropped to 16.56%.

[0034] For example, from a horizontal perspective of several days, when the ground temperature is cooling overall, the air pressure is rising overall. When the ground temperature is warming overall, the air pressure is decreasing overall. For example, from the 16th to the 21st, the ground temperature is cooling down, the temperature drops from 6℃ to -22.6℃, the ground pressure increases from 92.122KPa to 94.211KPa, an increase of 2089Pa; the underground air pressure increases from 90.93KPa to 92.924KPa, an increase of 1994Pa; the minimum oxygen concentration in the return air corner increases from 12.4% on the 16th to 19.07% on the 21st. It can be seen from this that during the cooling process, the underground air pressure and the ground air pressure increased synchronously as a whole, the gas was squeezed from the working surface to the goaf and was not easy to gush out, and the broken coal rock in the goaf continuously released nitrogen and carbon dioxide, thus forming a large area of ​​low-oxygen area in the goaf; from the 22nd to the 29th, the ground showed a warming trend, with the temperature rising from -22.1℃ to 4.6℃, and the ground air pressure decreasing from 94.242KPa to 91.682KPa, a decrease of 2777Pa; the underground air pressure decreased from 92.975KPa to 90.465KPa, a decrease of 2510Pa; the minimum oxygen concentration in the return air corner decreased from 18% on the 22nd to 11.63% on the 29th. It can be seen that during the temperature rise process, the underground air pressure and the ground air pressure decreased synchronously as a whole, the gas was released from the goaf to the working face, and the low-oxygen gas accumulated in the goaf gushed out abnormally. The 29th was the day with the largest temperature rise in this round. The underground air pressure dropped by 1298Pa compared with the previous day, and hypoxia reached the most serious state.

[0035] Therefore, a monitoring and early warning method is needed to give advance warning of gas exceeding the limit and hypoxia phenomena, so as to provide an effective safety reference for taking governance measures, arranging production, and avoiding disasters on site, and also provide a basis for activating the extraction system to achieve the purpose of saving electricity and reducing energy consumption. Through long-term observation, it is found that changes in ground temperature and air pressure have a significant impact on the abnormal outburst of gas and hypoxia in the goaf of coal mining working faces. The early warning involves the measurement of gas data of coal mining working faces in underground coal mines and the prediction method of hypoxia phenomena. The present invention uses a dedicated gas detector and early warning system to establish a database, and predicts the time period when gas exceeding the limit and hypoxia phenomena will occur according to the changes in temperature and air pressure in the weather forecast, so as to take advance warning of gas and hypoxia.

[0036] In order to solve the above problems, the present disclosure provides an early warning method, an early warning device and an electronic device, which obtain the temperature data of the area where the gas mine is located within a preset time period; determine the temperature difference within the preset time period based on the temperature data; and determine the target early warning plan of the gas mine based on the temperature difference. Through the above technical solution, the temperature data within the preset time period can be obtained through weather forecasts or historical data, and the target early warning plan of the gas mine can be determined according to the calculated temperature difference. Since the preset time period can be a time period of one or more days in the future, the early warning plan of the gas mine in the future time period can be obtained, which realizes early warning of accidents such as coal mine over-limit, and can give workers time to leave the dangerous area, ensuring the safety of the workers' body and life.

[0037] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0038] Figure 1 is a flow chart of an early warning method according to an exemplary embodiment. Figure 1 As shown, the early warning method includes the following steps.

[0039] In step S101, temperature data of the area where the gas mine is located within a preset time period is obtained.

[0040] In this embodiment, the area where the gas mine is located may be the administrative area where the gas mine is located, for example, the district, town, village, street, etc. where the gas mine is located.

[0041] In this embodiment, the preset time period may be one day, the preset time period may be three days, or the preset time period may be seven days, which is not specifically limited in this embodiment.

[0042] It should be noted that the preset time period may be a period of time in the future, or a period of time in the past. For example, the preset time period may be one day in the future, or the preset time period may be seven days in the past.

[0043] In this embodiment, the temperature data may include air temperature data in the weather forecast, and the temperature data may also include the highest temperature, the lowest temperature and the average temperature in a preset time period, wherein the unit of the temperature data is Celsius (°C).

[0044] In some embodiments, the temperature data includes: the highest temperature at the first time, the average temperature at the first time, and the lowest temperature at the first time, as well as the highest temperature at the second time, the average temperature at the second time, and the lowest temperature at the second time, the second time being earlier than the first time, and the second time and the first time are within a preset time period.

[0045] In some embodiments, step S101 includes: obtaining temperature data of the area where the gas mine is located in the next day through weather forecast.

[0046] In step S102, a temperature difference within a preset time period is determined according to the temperature data.

[0047] In some embodiments, there may be multiple temperature differences within a preset time period. For example, the temperature differences within a preset time period include: the highest temperature difference within the preset time period, the lowest temperature difference within the preset time period, and the average temperature difference within the preset time period.

[0048] In some embodiments, step S102 includes: determining the temperature difference within a preset time period based on the highest temperature at the first time and the highest temperature at the second time; or, determining the temperature difference within the preset time period based on the average temperature at the first time and the average temperature at the second time; or, determining the temperature difference within the preset time period based on the lowest temperature at the first time and the lowest temperature at the second time.

[0049] In step S103, a target early warning plan for a gas mine is determined according to the temperature difference.

[0050] In this embodiment, different temperature differences correspond to different target early warning schemes.

[0051] In some embodiments, the target warning scheme includes: a mining operation time period and a dangerous area within a preset time period.

[0052] It should be noted that due to the release of harmful gases in the goaf, high-concentration methane will flow into the working space of the working face, and the methane concentration in the return air corner and return air flow will increase. Therefore, for the sake of operational safety, it is necessary to issue early warnings for the mining operation time period and dangerous areas. For example, the target early warning plan includes: tomorrow's mining operation time period is from 8 am to 12 pm, and the dangerous area is the hydraulic supports numbered 1 to 20 in the return air corner.

[0053] In some embodiments, the target warning scheme includes the danger level of the gas mine within a preset time period and the emergency measures corresponding to the danger level. For example, the emergency measures include: all workers entering the coal mining face and its return air chute wear methane oxygen and carbon monoxide portable instruments.

[0054] Through the above method, temperature data within a preset time period can be obtained through weather forecasts or historical data, and the target early warning plan for the gas mine can be determined based on the calculated temperature difference. Since the preset time period can be a period of one or more days in the future, an early warning plan for the gas mine in the future time period can be obtained, thereby achieving early warning of accidents such as coal mine over-limit, thereby giving workers time to leave the dangerous area and ensuring the safety of their bodies and lives.

[0055] In some embodiments, the temperature difference includes a first temperature difference, a second temperature difference, and a third temperature difference, and step S102 includes: taking the difference between the highest temperature at the first time and the highest temperature at the second time as the first temperature difference; taking the difference between the average temperature at the first time and the average temperature at the second time as the second temperature difference; The difference between the lowest temperature at the first time and the lowest temperature at the second time is taken as the third temperature difference.

[0056] In this embodiment, the first temperature difference is the highest temperature difference in the preset time period, the second temperature difference is the average temperature difference in the preset time period, and the third temperature difference is the lowest temperature difference in the preset time period.

[0057] Exemplarily, the first time may be tomorrow, the second time may be today, the first temperature difference is the maximum temperature difference between tomorrow and today, the second temperature difference is the average temperature difference between tomorrow and today, and the third temperature difference is the minimum temperature difference between tomorrow and today.

[0058] Through the above method, the maximum temperature difference, average temperature difference and minimum temperature difference within the preset time period are determined, which is conducive to advance warning of abnormal outbursts of toxic and harmful gases such as coal mine gas and hypoxia based on weather forecast information.

[0059] In some embodiments, the above-mentioned early warning method further includes: Get preset temperature difference ranges corresponding to multiple preset danger levels.

[0060] In this embodiment, different danger levels have different temperature difference ranges.

[0061] For example, the multiple preset danger levels include: level 1, level 2, level 3 and level 4, and the danger level increases with the level. For another example, the multiple preset danger levels include: blue warning, yellow warning, orange warning and red warning, and the danger level increases in sequence.

[0062] See also Figure 2 , step S103 includes the following steps: In step S1031, according to a preset temperature difference range, a first danger level corresponding to the first temperature difference, a second danger level corresponding to the second temperature difference, and a third danger level corresponding to the third temperature difference are determined.

[0063] In this embodiment, different types of temperature differences have different temperature difference ranges. For example, the danger levels corresponding to different types of temperature differences can be determined through Table 1.

[0064] Table 1

[0065] In practical applications, the temperature differences of the same type corresponding to different types of temperature differences can also be calibrated through a large amount of experimental data.

[0066] In step S1032, a target early warning plan for the gas mine is determined according to the first hazard level, the second hazard level, and the third hazard level.

[0067] In some embodiments, step S1032 includes: The most dangerous level among the first, second and third danger levels is taken as the target danger level; The early warning plan corresponding to the target danger level is used as the target early warning plan, and different danger levels correspond to different early warning plans.

[0068] It is understandable that, for safety reasons, when the first danger level, the second danger level and the third danger level have different danger levels, taking the one with the highest danger level as the target danger level can effectively prevent accidents from occurring.

[0069] In some embodiments, the target warning scheme includes: mining operation time periods and dangerous areas corresponding to the target danger levels.

[0070] For example, the mining operation time period may be from 8:00 to 12:00, and the operation content may include return air corner, rear conveyor, and chute belt maintenance operations.

[0071] In this embodiment, the dangerous area refers to an area that is susceptible to abnormal gas outflow, for example, hydraulic supports with different numbers at the return air corners.

[0072] In this embodiment, the target danger level has different mine operation time periods and danger zones. For example, the mine operation time periods and danger zones can be determined by Table 2.

[0073] Table 2

[0074] In actual applications, the time periods and dangerous areas for the same type of mining operations corresponding to different danger levels can be set according to actual needs.

[0075] Through the above method, the target danger level is first determined according to the temperature difference, and then the target early warning plan for the gas mine is obtained according to the target danger level. The severity and impact range of abnormal outburst of toxic and harmful gases in the goaf are obtained, which provides time preparation for preventing gas exceeding the limit, hypoxia asphyxiation, and gas explosion.

[0076] In some embodiments, step S103 further includes the following steps: According to the first temperature difference, the second temperature difference and the third temperature difference, a target danger level of the gas mine is determined, and the danger levels include blue warning, yellow warning, orange warning and red warning, and the danger levels increase in sequence; Determine the target early warning plan for gas mines based on the target hazard level.

[0077] In one possible implementation, the hazard level of a gas mine may be determined in the following manner: When the first temperature difference, the second temperature difference and the third temperature difference all fall within the temperature difference range of the blue warning, the blue warning is used as the target danger level; When any one of the first temperature difference, the second temperature difference and the third temperature difference falls within the temperature difference range of the yellow warning, the yellow warning is used as the target danger level; When any one of the first temperature difference, the second temperature difference and the third temperature difference falls within the temperature difference range of orange warning, orange warning is used as the target danger level; In the case that any one of the first temperature difference, the second temperature difference and the third temperature difference belongs to the temperature difference range of the red warning, the red warning is used as the target danger level.

[0078] Through the above method, the target danger level is first determined according to the temperature difference, which provides time preparation for preventing gas exceeding the limit, hypoxia asphyxiation, and gas explosion.

[0079] In some embodiments, the above-mentioned early warning method further includes: The warning information is output through the terminal, and the warning information includes the target warning plan, the target danger level and the historical temperature data.

[0080] Through the above method, various data of the early warning software can be viewed in real time from the mobile phone, and early warnings can be received, which is convenient for personnel to grasp information in time, arrange production plans reasonably through early warning forecasts, and take preventive measures in advance.
