Description

Technical Field

[0001] This invention belongs to the field of environmental protection and carbon emission accounting technology, specifically to the method and related apparatus for calculating carbon emission reduction from coal gangue ecological backfilling and land reclamation. Background Technology

[0002] Coal dominates my country's energy structure, but its mining and washing processes generate a large amount of coal gangue. Statistics show that my country's annual coal gangue emissions are enormous, accumulating into thousands of gangue mountains that occupy vast amounts of land resources. Due to its high carbon content and the risk of spontaneous combustion, coal gangue represents a huge potential source of carbon emissions. Simultaneously, surface subsidence caused by mining activities damages the carbon sink function of existing ecosystems. Using coal gangue to fill mining subsidence areas and for land reclamation is an effective technological approach for synergistically reducing pollution and carbon emissions. It can both fix the carbon in the coal gangue, preventing its accumulation and emission, and restore the ecological function of the land, increasing the carbon storage of the ecosystem.

[0003] However, the net carbon reduction benefits of existing methods are calculated based on a single factor, such as calculating only vegetation carbon sequestration, which fails to comprehensively cover the entire life cycle carbon flow from coal gangue disposal and construction to ecological restoration, resulting in incomplete assessment results and large deviations from actual results.

[0023] Compared with the prior art, the present invention has the following beneficial technical effects: This invention proposes a method for calculating carbon emission reductions from ecological backfilling and land reclamation of coal gangue. This method obtains the spatial boundaries and carbon pool boundaries of the ecological backfilling and land reclamation areas and constructs a simulation scenario to clarify the spatial scope of the calculation. By incorporating multiple factors in the simulation scenario, it integrates the influence of multiple factors, overcoming the biases caused by ambiguous scope definition and inaccurate calculation bases in single-factor calculations. Then, based on a preset time boundary, it simultaneously conducts comparative simulations of treated and untreated coal gangue. The obtained simulation data comprehensively reflects the differences in carbon changes under different scenarios, compensating for the shortcomings of single-factor calculations, such as incomplete data and failure to consider comparative scenarios. This approach makes the calculated data more reliable. Then, through simulated data, it calculates four core dimensions: potential carbon emission reduction from coal gangue storage, new carbon sinks from the project, emission reduction through substitution, and carbon emissions from project activities. This covers the entire process of carbon emission reduction and emission control, overcoming the limitations of calculating only one dimension while ignoring other key factors, ensuring completeness of the calculation dimensions. Finally, it integrates data from all four dimensions to calculate net carbon emission reduction, comprehensively considering both emission reduction and emission factors. This avoids overestimation or underestimation of the assessment results caused by single-factor calculations, ensuring the assessment results are highly consistent with actual engineering scenarios and significantly improving the accuracy and completeness of the net carbon emission reduction benefit assessment.

Detailed Implementation

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] This invention proposes a method for calculating carbon emission reductions from ecological backfilling of coal gangue and land reclamation, such as... Figure 1 As shown, it includes the following steps: The spatial boundaries of historical coal gangue ecological backfilling and land reclamation, as well as the carbon pool boundary, are obtained. A simulation scenario is constructed based on these boundaries. Based on a preset time boundary, simulations of coal gangue treatment and untreated coal gangue are conducted within the simulation scenario to obtain simulation data. Based on the simulation data, the potential carbon emission reduction from coal gangue stockpiling, the new carbon sink from the project, the alternative emission reduction, and the carbon emissions from project activities are calculated. The net carbon emission reduction is calculated based on the potential carbon emission reduction from coal gangue stockpiling, the new carbon sink from the project, the alternative emission reduction, and the carbon emissions from project activities.

[0028] This method clarifies the accounting scope by acquiring the spatial boundaries of ecological backfilling and land reclamation of coal gangue and the boundaries of the carbon pool, and constructing a simulation scenario. This avoids the bias caused by the ambiguity of the scope definition in single-factor accounting and lays a precise spatial foundation for subsequent accounting. Secondly, based on a preset time boundary, a comparative simulation of coal gangue treatment and untreatment is carried out simultaneously. The obtained simulation data comprehensively reflects the differences in carbon changes under different scenarios, making up for the shortcomings of one-sided data in single-factor accounting. Furthermore, by calculating the potential carbon emission reduction of coal gangue stockpiling, the new carbon sink of the project, the emission reduction through substitution, and the carbon emission of project activities, this method covers the entire process of carbon emission reduction and emission, breaking the limitations of single-factor accounting and ensuring the completeness of accounting dimensions. Finally, by integrating multi-dimensional data to calculate net carbon emission reduction, this method comprehensively considers both emission reduction and emission factors, making the assessment results more consistent with the actual engineering scenario and avoiding overestimation or underestimation caused by single-factor accounting. This achieves a comprehensive, accurate, and realistic assessment of net carbon emission reduction benefits.

[0029] Furthermore, the spatial boundaries of historical coal gangue ecological backfilling and land reclamation, as well as the carbon pool boundary, are obtained. Based on the spatial boundaries and carbon pool boundary, a simulation scenario is constructed. The spatial boundary includes the backfill area, the reclamation area, and the geographical coordinates. The carbon pool boundary includes the biomass, litter, soil organic carbon, and methane emission sources from the coal gangue pile within the backfill area and the reclamation area.

The geographic coordinates of the reclamation area are located by remote sensing satellite or UAV technology, and the outer contour of the reclamation area is collected to construct the scope of the reclamation area. Based on the scope of the backfill area and the scope of the reclamation area, a simulated initial scene is constructed. By using drones equipped with image acquisition capabilities, images of litter, above-ground organisms, and methane emission source data from soil organic carbon and coal gangue piles were collected within the backfill and reclamation areas. This allowed for the acquisition of litter data and above-ground organisms. Furthermore, by detecting subsurface organisms, the subsurface biomass was obtained. The simulation scenario is obtained by fitting underground biomass, soil organic carbon, methane emission source data from coal gangue piles and litter data, as well as aboveground biomass, into the initial simulation scenario. Based on a preset time boundary, simulations of coal gangue treatment and untreated coal gangue were conducted in a simulated scenario to obtain simulation data. The time length from the start of coal gangue backfilling to the end of the accounting period in historical coal gangue ecological backfilling and land reclamation was obtained and recorded as the time boundary. Specifically, a time boundary was set for the simulation scenario to simulate the following scenarios: coal gangue continued to be open-pit stored in the gangue pile without any projects, and the land remained in a state of mining damage; and the state after implementing projects such as coal gangue ecological backfilling, land leveling, soil improvement, and vegetation reconstruction. The simulation data included the amount of coal gangue backfilled, the carbon emission factor of coal gangue storage, the increase in vegetation carbon pool, vegetation distribution area, vegetation carbon content, soil carbon pool increase, reclamation area, soil bulk density, soil layer thickness, changes in soil organic carbon content, the proportion of coal gangue replacing traditional materials, the carbon emission factor of traditional building materials, and the carbon emission factor of coal gangue as a building material. The potential carbon emission reduction from coal gangue stockpiling, the increase in ecosystem carbon sinks, and the alternative emission reductions calculated based on simulation data include: Based on the amount of coal gangue backfill and the carbon emission factor of coal gangue stockpiles in the simulation data, the potential carbon emission reduction of coal gangue stockpiles is calculated with the collected carbon emission potential value. The vegetation carbon pool increment was calculated based on the vegetation carbon pool increment, vegetation distribution area and vegetation carbon content in the simulation data. Soil carbon sink was calculated based on the changes in soil carbon pool increment, reclaimed area, soil bulk density, soil layer thickness, and soil organic carbon content in the simulation data. The newly added carbon sequestration of the project was calculated based on the increase in soil carbon sequestration and vegetation carbon pool. The emission reduction was calculated based on the proportion of coal gangue replacing traditional materials in the simulation data, as well as the carbon emission factors of traditional building materials and coal gangue as the carbon emission factor of building materials. The carbon emissions of the project activities were calculated based on the energy consumption data from the simulation and the obtained energy carbon emission factor.
