Description

Technical Field

[0001] This invention relates to the field of carbon emission accounting technology in the coal mining industry, and in particular to a method and system for quantifying carbon emissions throughout the entire life cycle of a mining area that considers multiple factors. Background Technology

[0002] The main methods for measuring carbon emissions in mining areas include the emission factor method, the measured method, the mass balance method, the life cycle method, and the input-output method, among others. Different methods have different advantages and disadvantages, application procedures, and related materials. Currently, my country's power industry mainly focuses on developing carbon metering service terminals to achieve real-time monitoring of the entire power generation process; the cement industry optimizes the mass balance method combined with the emission factor method to address carbon emissions from limestone decomposition (accounting for over 60%). Coal mining areas primarily use the emission factor method for accounting.

[0003] Patent No. CN118152722A discloses a device, method, equipment and medium for the full life cycle accounting of carbon emissions from rural sewage treatment facilities. It integrates the "emission factor method" and the "mass balance method" to achieve quantitative evaluation of carbon emissions at each stage of construction, operation and dismantling of rural sewage treatment facilities.

[0004] Patent No. CN118396484A discloses a method and system for calculating road carbon emissions based on the whole life cycle theory. According to the specific situation of each stage, it quantifies the energy consumption and carbon emissions of each stage and provides a clear and easy-to-use carbon emission assessment method.

[0005] As can be seen from the aforementioned patents, carbon emission statistics in mining areas are a crucial foundation for promoting the green and low-carbon transformation of the mining industry. However, existing methods have significant limitations, especially in terms of climate and regional adaptability. Firstly, climate factors are missing: traditional models do not quantify the impact of climate parameters on equipment energy consumption and ecological restoration. For example, in high-altitude and cold regions, mining equipment efficiency decreases by 10-15% due to low temperatures, and increased diesel viscosity leads to incomplete combustion, requiring an 8-12% increase in carbon emission factors; while in arid regions, vegetation restoration requires additional irrigation energy consumption, increasing implicit carbon emissions by 15-20%. Secondly, regional characteristics are simplified: current methods ignore regional differences in carbon sequestration capacity, uniformly adopting the national average vegetation carbon sequestration factor. Studies have shown that the carbon sequestration capacity per unit area of ​​temperate broadleaf forests (…) )Biya Arctic coniferous forest ( The vegetation recovery cycle in high-altitude mining areas (>3000m) is 60% longer than in low-altitude areas, and the carbon sink loss is underestimated by 38%. Life cycle gaps: Existing technologies mostly focus on energy consumption emissions during the mining period, with insufficient coverage of carbon sink baseline surveys during the planning period and carbon balance monitoring during the restoration period. Furthermore, there is no dynamic correlation model between carbon sink increments and climate conditions during the restoration period. Insufficient data dynamism: Accounting relies on static emission factors and does not incorporate updated electricity emission factors based on regional energy structure.

[0006] Therefore, there is an urgent need to develop a carbon emission quantification method that integrates dynamic correction of climate parameters, precise quantification of regional carbon sinks, and full life cycle coverage to support the formulation of differentiated emission reduction strategies for mining areas.

[0043] It should be explained that this invention provides a method for quantifying carbon emissions throughout the entire life cycle of coal mining areas, which is divided into three stages: planning period, mining period, and restoration period. The method combines climate-regional influencing factors to construct a carbon emission quantification model.

[0044] like Figure 1-2 As shown in the embodiment of the present invention, a method for quantifying carbon emissions throughout the entire life cycle of a mining area that considers multiple factors includes three stages: planning period, mining period, and restoration period. The following is a detailed description and explanation.

[0045] First, a survey of the basic conditions of the mining area is conducted to understand its climate, geographical location, and ecological structure. Then, the different stages of carbon emissions in the mining area are identified, and carbon emissions are calculated in stages.

[0046] The first stage is the planning period. In this stage, technologies such as Sentinel-2 remote sensing imagery or drone aerial photography are used to identify the vegetation types and coverage areas (S1, S2, ... S) of the planning area through scanning or aerial photography. n The carbon sink baseline value is calculated using the following formula. C base : ; In the formula, C base This represents the quantitative value of the carbon sink baseline during the planning period, providing a benchmark value for subsequent calculations; V i Indicates vegetation i Theoretical carbon sequestration rate per unit area ( If the identified vegetation type is not a carbon sink indicator, then V i Recorded as 0;S i Indicates the first i The area covered by vegetation type; F climate Indicates the climate adjustment factor; F altitude The altitude adjustment coefficient is shown in Table 1, and is selected based on the range of values.

[0047] Table 1: Selection Ranges for Climate Adjustment Coefficient and Altitude Adjustment Coefficient ; The second stage is the mining period, which introduces a climate-energy coupling algorithm to quantify direct and indirect emissions. That is, dynamic emission factors are added to the calculation of carbon emissions from energy consumption, taking into account the impact of factors such as climate on carbon emissions.

[0048] First, direct and indirect emission sources were identified according to the national standard "Greenhouse Gas Accounting and Reporting Requirements Part 11: Coal Production Enterprises" (GB / T32151.11-2018). By identifying different emission sources, all energy consumption types in the coal mining area were summarized. Table 2 shows the definition of climate-regional impact factors, including but not limited to those listed below. These factors need to be modified and adjusted according to the actual conditions of the mine. Based on Table 2, the relevant parameters were adjusted.

[0049] Table 2: Definitions of Climate-Regional Influencing Factors ; For example, the formula for calculating carbon emissions from diesel consumption is: diesel consumption Dynamic emission factors EF diesel In this step, the diesel emission factors for high-altitude and cold regions are corrected, using... Where γ is 0.25-0.35, CC represents the carbon content per unit calorific value of diesel fuel, reflecting the total amount of carbon released during diesel combustion. The higher the carbon content of diesel fuel, the more carbon dioxide (CO2) is produced during combustion. The more OF, the higher the oxidation rate; 44 / 12 represents the oxidation rate. Molecular weight conversion factor.

[0050] For example, equipment energy consumption is related to equipment startup efficiency. Generally, improved equipment efficiency leads to lower coal consumption for power generation and reduced carbon emissions from electricity generation. Furthermore, different startup efficiencies are used for different climate zones, thus establishing a climate-energy consumption coupling relationship and enabling the calculation of carbon emissions, such as carbon emissions per unit of electricity generation = coal consumption per unit of electricity generation. (Coal-fired carbon emission factor) ∝ 1 / η. For example, the road friction coefficient is different in different climate zones, and the relationship between the road friction coefficient and fuel consumption can be expressed as follows: for every 0.01 increase in μ, fuel consumption increases by an average of 2.5%-4%, especially in heavy-duty scenarios such as mining trucks.

[0051] Based on this, calculate It calculates the total carbon emissions generated by all energy consumption. Among them, AD i Representing the i Energy-related activity data, such as the consumption of diesel, gasoline, and electricity (unit: liters or kilowatt-hours), for example, diesel consumption ( Purchased electricity () ). EF i Representing the i The dynamic emission factors of energy sources are adjusted by regional factors such as climate and altitude. For example, the formula for calculating the emission factors of diesel vehicles in high-altitude and cold regions mentioned earlier.

[0052] The formula for calculating the carbon sink loss during the mining period is: ; In the formula, C loss Indicates the value of carbon sequestration loss; S loss Indicates carbon sequestration capacity; K This indicates the difficulty level of restoration, particularly in ecologically fragile areas. K Take 1.5, stable region K Take 1.0.

[0053] The third stage is the restoration period, during which a carbon balance assessment model is built to predict the carbon sequestration trajectory of vegetation. The formula for calculating the expected carbon sink compensation value in this stage is: ; In the formula, C comp This indicates the expected carbon offset value; C base This represents the quantitative value of the carbon sink baseline during the planning period; α This represents the conversion rate of plantation maturity (0.4 for arid regions and 0.8 for humid regions). β This represents the climate-driven growth rate (this value decreases by 0.02 for every 1°C decrease in temperature). t Indicates time.

[0054] Using the carbon sequestration maturity index CMI To assess carbon sequestration recovery, a certain indicator value indicates efficient remediation during the mine's restoration period, and carbon sequestration during this phase should be considered in calculations. Otherwise, carbon sequestration during this restoration period should not be considered. Ccomp The formula for calculating the carbon sink maturity index is: ; In the formula, CMI This represents the carbon sink maturity index; C comp This indicates the expected carbon offset value; C base This represents the quantitative value of the carbon sink baseline during the planning period. If the carbon sink maturity index... CMI If the value is less than 0.8, then Δ C comp =0; if the carbon sink maturity index CMI If the value is greater than 0.8, then Δ C comp = C comp .

[0055] Finally, combining the output results from the three stages, the formula for calculating the net carbon emissions of the mining area is as follows: ; In the formula, Δ C Representing net emission equivalent, it indicates the actual net carbon emissions after considering comprehensive energy consumption, ecological losses, and restoration compensation during the mining period, expressed in tons. equivalent; C loss This represents the carbon sink loss value, which is the reduction in carbon absorption capacity due to vegetation destruction; Δ C comp The actual carbon sequestration compensation value refers to the increase in carbon sequestration caused by artificial restoration of vegetation. AD i Indicates the first i Energy-related activity data; EF i Indicates the first i Dynamic emission factors of energy sources.
