[0002] Coal resources are a core pillar of energy security and play a vital role in ensuring economic and social development. However, spontaneous combustion in coal seams can occur due to heating or unextinguished surface flames, forming fire zones. These fire zones, especially those with long histories of spontaneous combustion, emit large amounts of greenhouse gases such as carbon dioxide, methane, and nitrous oxide. Furthermore, the spreading nature of some of these fire zones exacerbates global climate change and negatively impacts the economy, society, and the environment. Therefore, monitoring carbon dioxide emissions from spontaneous combustion fire zones is crucial for environmental oversight.

[0017] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained in accordance with the structures particularly pointed out in the description, claims and drawings.

[0018] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0019] To more clearly illustrate the specific embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the specific embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.

[0020] Figure 1 A flowchart illustrating a method for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, provided as an embodiment of the present invention; Figure 2 This is a schematic diagram of a device for calculating carbon dioxide emissions from a coal seam spontaneous combustion zone, provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of an electronic device provided in an embodiment of the present invention. Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Currently, the main methods for calculating carbon emissions include the emission factor method, the mass balance method, and the measured method. The emission factor method uses the product of activity data and the emission factor as an estimate of carbon emissions. The mass balance method estimates carbon emissions based on the amount of material entering and leaving the fire zone and the carbon content of the material. The measured method estimates carbon emissions through gas monitoring of emission sources. In addition, there are other methods for calculating carbon emissions from fire zones, such as the loss on ignition (LOI) method, the thermal anomaly inversion method, and the emission flux method. The LIO method estimates the amount of coal lost due to combustion in the fire zone, combining this with the elemental composition of the coal and the combustion chemical equation to calculate carbon emissions. The thermal anomaly inversion method uses airborne thermal infrared imaging to calculate heat flux and combines it with the calorific value of coal to estimate the amount of coal burned per unit time, thus calculating carbon emissions. The emission flux method measures carbon dioxide flux using static chamber methods and gas analyzers to calculate carbon emissions.

[0023] However, the aforementioned methods for calculating carbon emissions still have shortcomings when applied to calculating carbon dioxide emissions from spontaneous combustion coal seams. Specifically: for the emission factor method, the activity level is characterized by the amount of coal burned, i.e., the loss on ignition (LOI); for the mass balance method, its calculation results are mainly affected by the amount of material entering and leaving the coal seam, i.e., the LOI; and for the LOI method, its calculation results are mainly affected by the LOI. Therefore, the uncertainties of the emission factor method, mass balance method, and LOI method mainly stem from the accuracy of the LOI estimation, which depends on the precision of geological exploration and the three-dimensional spatial judgment of the combustion range and depth of the fire zone. As for the methods for calculating carbon emissions from spontaneous combustion coal seams, the uncertainty of the thermal anomaly inversion method mainly stems from the spontaneous combustion depth of the coal seam, the characteristics of the overlying strata, and thermal conductivity; while the uncertainties of the measured method and the emission flux method mainly stem from the judgment of the fire zone's extent and the identification of emission channels. Therefore, there is an urgent need to develop an accounting method for carbon dioxide emissions from spontaneous combustion zones in coal seams, in order to make up for the deficiencies in the aforementioned related technologies and to enhance the supervision of carbon dioxide emissions from spontaneous combustion zones in coal seams.

[0024] Based on this, embodiments of the present invention provide a method and apparatus for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, in order to alleviate the aforementioned technical problems.

[0025] To facilitate understanding of this embodiment, a detailed description of the method for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, as disclosed in this embodiment of the invention, will be provided first.

[0026] In one possible implementation, embodiments of the present invention provide a method for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, such as... Figure 1 The flowchart shown illustrates a method for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams. This method includes the following steps: Step S102: Obtain the accounting data of the spontaneous combustion zone of the coal seam; In this embodiment of the invention, the accounting data includes the carbon dioxide emission channels contained in the coal seam spontaneous combustion zone and the attribute information of the carbon dioxide emission channels. Step S104: Based on the attribute information of the carbon dioxide emission channels and the carbon dioxide emission flux of each carbon dioxide emission channel obtained through pre-monitoring, calculate the carbon dioxide emission of each carbon dioxide emission channel. In practical applications, data analysis, on-site reconnaissance, and methods such as thermal infrared remote sensing can be used to determine the geographical location and vector boundaries of spontaneous combustion zones in coal seams, and to identify carbon dioxide emission channels such as surface subsidence, pores, and fissures within these zones. This provides a basis for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams. These data can be stored in a corresponding database as carbon dioxide emission channels and their attribute information, providing data support for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams.

[0027] Step S106: Summarize the carbon dioxide emissions of each carbon dioxide emission channel to obtain the carbon dioxide emissions of the coal seam spontaneous combustion zone.

[0028] This invention provides a method for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams. It acquires data on spontaneous combustion zones and calculates the carbon dioxide emissions for each emission channel based on the attribute information of the emission channels and the pre-monitored carbon dioxide emission flux. The carbon dioxide emissions from each emission channel are then aggregated to obtain the total carbon dioxide emissions for the spontaneous combustion zone. Since the carbon dioxide emission flux is surface data, it is less affected by underground factors, has relatively low uncertainty, and is easier to obtain. During the calculation process, carbon dioxide emission channels are used as the basic unit. The distribution and emission information of these channels can further reveal the spatial differences in spontaneous combustion and carbon dioxide emissions within the coal seam, clarifying the carbon dioxide emission situation of the entire spontaneous combustion zone. This provides technological support for the governance and ecological environment monitoring of spontaneous combustion zones, enabling the assessment of the governance effectiveness and ensuring long-term effectiveness to prevent reignition.

[0029] Generally, the aforementioned coal seam spontaneous combustion zone in this embodiment of the invention refers to the area where naturally buried coal seams spontaneously combust due to oxidation and heat release upon contact with air during mining or before mining, with heat accumulating to the ignition point. Within the coal seam spontaneous combustion zone, the characteristics of spontaneous combustion, such as combustion area, combustion depth, combustion degree, loss on ignition, carbon dioxide release factor, and emission factor, are concealed. This leads to uncertainties in the calculation results of related technologies such as the emission factor method, mass balance method, and loss on ignition method.

[0030] Given the concealed nature of coal seam spontaneous combustion characteristics, and especially the uncertainty in the calculation results of carbon dioxide emissions from coal seam spontaneous combustion fire zones based on coal loss on ignition, in this embodiment of the invention, in step S104 above, when calculating the carbon dioxide emissions of each carbon dioxide emission channel, it is necessary to extract the area parameter of each carbon dioxide emission channel from the attribute information; and calculate the carbon dioxide emissions of each carbon dioxide emission channel based on the area parameter and the carbon dioxide emission flux of each carbon dioxide emission channel.

[0031] Specifically, in this embodiment of the invention, carbon dioxide emission flux is used to characterize the amount of carbon dioxide emitted per unit time and per unit area of ​​a carbon dioxide emission channel. When calculating the amount of carbon dioxide emitted by each carbon dioxide emission channel based on the area parameter and the carbon dioxide emission flux of the carbon dioxide emission channel, the amount of carbon dioxide emitted by each carbon dioxide emission channel can be obtained by calculating the product of the area parameter and the carbon dioxide emission flux.

[0032] In other words, in this embodiment of the invention, for each carbon dioxide emission channel, the product of the area parameter of the carbon dioxide emission channel and the carbon dioxide emission flux is used as a measure of carbon dioxide emissions in the coal seam spontaneous combustion fire zone. This allows for a more accurate calculation of the total carbon dioxide emissions in the entire coal seam spontaneous combustion fire zone. Furthermore, using the product of the carbon dioxide emission channel area and the carbon dioxide emission flux as a measure of carbon dioxide emissions in the coal seam spontaneous combustion fire zone reduces the uncertainty in the calculation results caused by the concealment of coal seam spontaneous combustion and underground factors, thus improving the scientific validity and accuracy of the carbon dioxide emissions measurement in the coal seam spontaneous combustion fire zone. Moreover, using the product of the carbon dioxide emission channel area and the carbon dioxide emission flux as a measure of carbon dioxide emissions in the coal seam spontaneous combustion fire zone ensures that the obtained data is mainly concentrated on the surface of the fire zone, reducing data acquisition costs and the costs of monitoring and calculating carbon dioxide emissions in the coal seam spontaneous combustion fire zone.

[0033] In practical applications, to obtain the aforementioned accounting data, it is typically necessary to acquire pre-recorded data on spontaneous combustion zones in coal seams. Then, the geographical location, vector boundaries, and distribution information of carbon dioxide emission channels within these zones are extracted from the data. Specifically, this data can be obtained through data collection and analysis, on-site reconnaissance, and remote sensing monitoring. For example, during data collection and analysis, relevant data on spontaneous combustion zones in coal seams can be systematically collected, their formation history and evolution trends analyzed, and data on their geographical location, vector boundaries, and carbon dioxide emission channels summarized. On-site reconnaissance typically involves conducting a comprehensive on-site survey of spontaneous combustion zones in coal seams. Based on characteristics of spontaneous combustion such as thermal anomalies, vegetation dieback, and gas emissions, the geographical location, vector boundaries, and carbon dioxide emission channels of the spontaneous combustion zones are identified, and the corresponding geographical coordinates are extracted simultaneously. Furthermore, the remote sensing monitoring method usually refers to using remote sensing technologies such as thermal infrared to identify the geographical location, vector boundary, and carbon dioxide emission channels of the coal seam spontaneous combustion zone. The data information obtained from the above methods can be summarized and deduplicated to obtain the data information required in the embodiments of the present invention.

[0034] Furthermore, in this embodiment of the invention, after extracting the geographical location of the coal seam spontaneous combustion zone, the vector boundary of the coal seam spontaneous combustion zone, and the distribution information of the carbon dioxide emission channels contained in the coal seam spontaneous combustion zone from the above data information, the area parameter of each carbon dioxide emission channel can be measured one by one based on the vector boundary of the coal seam spontaneous combustion zone and the distribution information of the carbon dioxide emission channels; then, each carbon dioxide emission channel in the coal seam spontaneous combustion zone is encoded to obtain accounting data; therefore, the accounting data in this embodiment of the invention typically includes vector data and attribute information of the carbon dioxide emission channels; the vector data includes the geographical location of the coal seam spontaneous combustion zone, the vector boundary of the coal seam spontaneous combustion zone, and the distribution information of the carbon dioxide emission channels; the attribute information records the area parameter of the carbon dioxide emission channels.

[0035] When measuring the area parameters of each carbon dioxide emission channel, the distribution information of the carbon dioxide emission channels can be used to measure the area parameters of surface subsidence, cracks, pores, etc. in the spontaneous combustion zone of the coal seam one by one through on-site measurement, remote sensing interpretation, etc., and these parameters can be used as attribute information of the carbon dioxide emission channels in the spontaneous combustion zone of the coal seam to establish an attribute database of the carbon dioxide emission channels in the spontaneous combustion zone of the coal seam.

[0036] Furthermore, in this embodiment of the invention, in order to realize the calculation process in step S104 above, it is usually necessary to carry out carbon dioxide emission monitoring for each carbon dioxide emission channel in the coal seam spontaneous combustion zone. Specifically, in this embodiment of the invention, monitoring data of the monitoring equipment deployed in the carbon dioxide emission channel can be obtained, and the monitoring data includes carbon dioxide concentration data during the monitoring period; the carbon dioxide emission flux of the carbon dioxide emission channel is calculated based on the monitoring data.

[0037] For example, static chambers and gas analyzers can be used to set up static chambers and gas sample collection points along the carbon dioxide emission channels as monitoring equipment, and then the carbon dioxide emission flux of each carbon dioxide emission channel in the spontaneous combustion zone of the coal seam can be monitored.

[0038] Specifically, when calculating the carbon dioxide emission flux of a carbon dioxide emission channel, the concentration difference of carbon dioxide concentration data within the monitoring period can be calculated based on monitoring data; the carbon dioxide emission flux of the emission channel can then be calculated based on the concentration difference. For example, based on the conditions of carbon dioxide emission channels such as surface subsidence, cracks, and pores in the coal seam spontaneous combustion zone, a sampling method can be used to deploy carbon dioxide emission flux monitoring points. Monitoring equipment is deployed at each monitoring point, and methods such as the static box method and gas analyzers can be used to monitor the carbon dioxide emission flux in the coal seam spontaneous combustion zone and obtain carbon dioxide emission flux data. Taking the static box method as an example, the carbon dioxide emission flux of the emission channel can be expressed as: ; Among them, F i ρ represents the carbon dioxide emissions from the i-th carbon dioxide emission channel, expressed as the carbon dioxide emissions per unit time and per unit area, in grams per square meter per second; V represents the volume of the monitoring equipment enclosure, in cubic meters; ρ i0 ρ i1 The values ​​represent the carbon dioxide concentration inside the monitoring equipment's chamber at the beginning and end of the monitoring period, respectively, in grams per cubic meter; m represents the coverage area of ​​the corresponding chamber, such as the flux chamber's coverage area, in square meters; and t represents the duration of the monitoring period, in seconds.

[0039] Furthermore, based on the aforementioned carbon dioxide emission flux, the product of the area parameter and the carbon dioxide emission flux can be calculated to obtain the carbon dioxide emission amount of the carbon dioxide emission channel. Then, the carbon dioxide emission amounts of each carbon dioxide emission channel are summed to obtain the carbon dioxide emission amount of the coal seam spontaneous combustion zone. Specifically, the carbon dioxide emission amounts of each carbon dioxide emission channel within a preset time period are sequentially superimposed to obtain the carbon dioxide emission amount of the coal seam spontaneous combustion zone within that preset time period.

[0040] The formula for the carbon dioxide emissions from the coal seam spontaneous combustion zone within the preset time period is as follows:

[0041] Among them, E CO2 E represents the carbon dioxide emissions from the coal seam spontaneous combustion zone within a preset time period; T represents the preset time period, taking a preset time period of one year as an example. CO2 The unit is usually tons per year; F i S represents the carbon dioxide emission flux of the i-th carbon dioxide emission channel, indicating the carbon dioxide emission per unit time and per unit area, typically expressed in grams per square meter per second; i The area parameter of the i-th carbon dioxide emission channel is usually expressed in square meters; the preset time period T is usually expressed in seconds; and n represents the number of carbon dioxide emission channels.

[0042] In summary, the carbon dioxide emission calculation method for spontaneous combustion zones in coal seams provided in this invention, based on a thorough investigation of carbon emission calculation methods, particularly those related to spontaneous combustion zones in coal seams, and an in-depth analysis of the shortcomings of current carbon emission calculation methods in calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, uses the product of the area parameter of the carbon dioxide emission channel and the carbon dioxide emission flux as a measure of carbon dioxide emissions from spontaneous combustion zones in coal seams, thus reducing the uncertainty of the carbon dioxide emission calculation results. Furthermore, through data analysis, on-site investigation, and thermal... Methods such as infrared remote sensing can determine the geographical location, vector boundaries, and carbon dioxide emission channels of spontaneous combustion zones in coal seams. These emission channels can be coded to generate vector data on the geographical location, boundaries, and emission channels of the spontaneous combustion zones. Based on this data, carbon dioxide emissions from spontaneous combustion zones can be monitored to obtain area parameters and emission fluxes. The carbon dioxide emissions from spontaneous combustion zones can then be calculated using a specific formula. This provides an effective method for accurately understanding the carbon dioxide emissions from spontaneous combustion zones and the effectiveness of their remediation, laying a solid foundation for implementing remediation projects and including carbon reductions from spontaneous combustion zones in carbon trading.

[0043] Furthermore, based on the above embodiments, this invention also provides a device for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams, such as... Figure 2 The diagram shows a structural schematic of a device for calculating carbon dioxide emissions from spontaneous combustion zones in coal seams. The device includes: The acquisition module 20 is used to acquire the accounting data of the spontaneous combustion zone of the coal seam, wherein the accounting data includes the geographical location of the spontaneous combustion zone of the coal seam, the vector boundary of the spontaneous combustion zone of the coal seam, and the carbon dioxide emission channels contained in the spontaneous combustion zone of the coal seam and the attribute information of the carbon dioxide emission channels. The calculation module 22 is used to calculate the carbon dioxide emissions of each carbon dioxide emission channel based on the attribute information of the carbon dioxide emission channel and the carbon dioxide emission flux of each carbon dioxide emission channel obtained by pre-monitoring. The aggregation module 24 is used to aggregate the carbon dioxide emissions of each of the carbon dioxide emission channels to obtain the carbon dioxide emissions of the coal seam spontaneous combustion zone.
