Description

Technical Field

[0001] This invention relates to the field of mine ecological restoration technology, and in particular to a method, apparatus, equipment, medium and product for generating revegetation schemes for mining areas. Background Technology

[0002] During open-pit mining, large areas of exposed slopes are often created. These slopes commonly suffer from complex lithology, steep gradients, and soil scarcity, leading to severe damage to the ecosystem and posing safety hazards such as landslides and soil erosion. Mine slope revegetation is a core aspect of ecological restoration, and various techniques have been developed, including the floating planting trough method, the grid beam method, and the hydroseeding method.

[0003] The applicable conditions for different revegetation technologies vary significantly, and how to scientifically select the appropriate technology based on the actual slope conditions and regional characteristics has become a pain point in the industry. In existing technologies, the commonly used approach is a revegetation technology selection method based on a single indicator. This method mainly relies on a single indicator such as slope gradient or lithology, combined with engineering experience, to select a revegetation technology.

[0004] However, the selection of existing slope revegetation technologies relies on single indicators and human experience, which is highly subjective and lacks quantitative standards. Moreover, most projects are limited to the application of a single technology, making it difficult to adapt to the revegetation needs of complex slopes. This results in low vegetation survival rates, high risks of soil erosion or landslides, and difficulty in maintaining the revegetation effect in the long term. Summary of the Invention

[0005] The purpose of this invention is to provide a method, apparatus, equipment, medium, and product for generating revegetation schemes in mining areas. It can establish a quantitative matching model of multi-dimensional evaluation indicators and revegetation technologies for the revegetation needs and technical adaptability of exposed slopes in mines, thereby improving the accuracy of revegetation technology selection and plant configuration.

[0006] To achieve the above objectives, embodiments of the present invention provide a method for generating a revegetation scheme for a mining area, comprising: Collect basic land information and regional characteristic information of the target area, and convert them into engineering requirement values ​​of preset multi-dimensional evaluation indicators according to preset quantitative standards; Based on the historical greening project database, calculate the technology fit value of each greening technology on each of the aforementioned evaluation indicators; By combining the engineering requirement values ​​and the technology adaptation values ​​of all the aforementioned evaluation indicators, the multi-indicator comprehensive matching degree of each of the aforementioned greening technologies is calculated; When a single revegetation technology has a comprehensive matching degree of multiple indicators greater than or equal to a preset threshold, the single revegetation technology and its matching plant configuration scheme are output; otherwise, according to the preset combination technology matching principle, a combined revegetation technology consisting of at least two revegetation technologies is generated, and the combined revegetation technology and its matching plant configuration scheme are output to obtain the revegetation scheme for the target area.

[0008] As an improvement to the above scheme, the formula for calculating the single-index fit is:

[0009] The formula for calculating the comprehensive matching degree of the multiple indicators is as follows:

Let j be the regional correction coefficient for the i-th revegetation technology; The comprehensive matching degree of multiple indicators for the j-th revegetation technology, Let be the weight coefficient of the i-th evaluation indicator, and n be the total number of evaluation indicators.

[0011] As an improvement to the above scheme, obtaining the weight coefficient of each of the evaluation indicators includes: Based on the revegetation needs and planned utilization types of the target area, the weight coefficient of each evaluation indicator is determined.

[0012] As an improvement to the above scheme, the step of determining the weight coefficient of each evaluation indicator based on the revegetation needs and planned utilization type of the target area includes: Based on the revegetation needs of the target area, the basic weight coefficient of each evaluation indicator is determined using the analytic hierarchy process. The basic weight coefficients are dynamically adjusted according to the planning and utilization type of the target area to obtain the final weight coefficient of each evaluation indicator.

[0013] As an improvement to the above scheme, the land basic information includes lithological data, slope, and altitude; the regional characteristic information includes regional soil type, climate conditions, mine type, and geological hazard risk information. The evaluation indicators include lithology, slope, height, regional soil, geological disaster risk, time to effectiveness, greening effect requirements, durability, maintenance and management requirements, input costs, and plant compatibility.

[0014] As an improvement to the above scheme, the step of calculating the technology fit value of each revegetation technology on each of the aforementioned evaluation indicators based on the historical revegetation project database includes: Obtain a database of historical greening projects; wherein, the database records case data of several historical greening project cases; Based on all the case data, generate the performance distribution of each of the described revegetation technologies on each of the described evaluation indicators; Based on the performance distribution, the technology fit value of each revegetation technology on each of the evaluation indicators is quantified.

[0015] As an improvement to the above solution, the step of generating a combined greening technology consisting of at least two greening technologies according to a preset combination technology matching principle includes: The revegetation technologies are sorted in descending order of their comprehensive matching degree among the multiple indicators; The top k revegetation technologies are selected as candidate revegetation technologies; where k ≥ 1. Based on the preset combination technology matching principles, at least one other revegetation technology that matches the candidate revegetation technology is determined to form a candidate combination revegetation technology; wherein, the combination technology matching principles include at least one of the following: complementary adaptation principle, regional adaptation principle, and cost controllable principle; Feasibility verification is performed on each of the candidate combination revegetation technologies, and the candidate combination revegetation technologies that pass the verification are obtained as the final combination revegetation technologies.

[0016] This invention also provides a device for generating revegetation schemes for mining areas, comprising: The engineering demand value calculation module is used to collect land basic information and regional characteristic information of the target area, and convert them into engineering demand values ​​of preset multi-dimensional evaluation indicators according to preset quantitative standards. The technology adaptation value calculation module is used to calculate the technology adaptation value of each greening technology on each of the aforementioned evaluation indicators based on the historical greening project database. The comprehensive matching degree calculation module is used to calculate the multi-index comprehensive matching degree of each of the above-mentioned greening technologies by comprehensively considering the engineering requirement value and the technology adaptation value of all the above-mentioned evaluation indicators. The revegetation scheme output module is used to determine whether there is a single revegetation technology with a comprehensive matching degree of the multi-indicators greater than or equal to a preset threshold; if so, the single revegetation technology and its matching plant configuration scheme are output; if not, a combined revegetation technology consisting of at least two revegetation technologies is generated according to the preset combination technology matching principle, and the combined revegetation technology and its matching plant configuration scheme are output to obtain the revegetation scheme for the target area.

[0017] This invention also provides a device for generating a revegetation scheme for a mining area, including a processor, a memory, and a computer program stored in the memory and configured to be executed by the processor. When the processor executes the computer program, it implements the method for generating a revegetation scheme for a mining area as described in any of the above embodiments.

[0018] This invention also provides a computer-readable storage medium, which includes a stored computer program, wherein the computer program, when running, controls the device where the computer-readable storage medium is located to execute the method for generating a revegetation scheme for a mining area as described in any of the preceding embodiments.

This achieves comprehensive coverage and solves the problem of lack of regional adaptability. Furthermore, by combining actual mine engineering data as a quantitative basis, the engineering demand values ​​of multi-dimensional evaluation indicators and the technical adaptability values ​​of each revegetation technology on these indicators are quantified. This clarifies the supply and demand relationship between the revegetation needs of the target area and the revegetation technologies, calculates the comprehensive matching degree of each revegetation technology across multiple indicators, and effectively establishes a quantitative matching model between evaluation indicators and revegetation technologies. This improves the accuracy and efficiency of selecting revegetation technologies for the target area and eliminates the subjective influence of human experience. Moreover, in the absence of a single revegetation technology that meets the matching conditions, combined revegetation technologies are generated based on the principle of combining technologies. This improves the selection guidance for combined technologies, clarifies the matching principles and quantitative standards of combined technologies in different scenarios, and enhances the revegetation effect on complex mine slopes.

[0026] See Figure 1 This is a flowchart illustrating a method for generating a revegetation scheme for a mining area according to an embodiment of the present invention. The method includes steps S11 to S14: S11. Collect basic land information and regional characteristic information of the target area, and convert them into engineering requirement values ​​of preset multi-dimensional evaluation indicators according to preset quantitative standards. S12. Based on the historical greening project database, calculate the technical fit value of each greening technology on each of the aforementioned evaluation indicators; S13. Calculate the multi-indicator comprehensive matching degree of each of the above-mentioned greening technologies by combining the engineering requirement value and the technology adaptation value of all the above-mentioned evaluation indicators; S14. When there is a single revegetation technology with a comprehensive matching degree of the multi-indicators greater than or equal to a preset threshold, output the single revegetation technology and its matching plant configuration scheme; otherwise, according to the preset combination technology matching principle, generate a combined revegetation technology consisting of at least two revegetation technologies, output the combined revegetation technology and its matching plant configuration scheme, so as to obtain the revegetation scheme of the target area.

[0027] In this embodiment of the invention, the target area refers to a mining area with revegetation needs, including exposed mine slopes. To determine the revegetation plan for the target area, this embodiment pre-determines multi-dimensional evaluation indicators designed for the revegetation needs based on the characteristics of the mine. Through on-site investigation, geological exploration, and laboratory testing, land-based information and regional characteristic information of the target area are collected. The land-based information includes lithological data, slope, and altitude, while the regional characteristic information includes regional soil type, climate conditions, mine type, and geological hazard risk information.

[0028] The specific contents of the land basic information and the regional characteristic information are as follows: Lithological data: Determine the rock type of the slope (e.g., hard rock / granite, soft rock, soil) and the degree of weathering (including strong weathering, moderate weathering, and slight weathering). Slope gradient (°): Classification of slope gradient (e.g., gentle slope <30°, medium slope 30°-60°, steep slope 60°-90°); Height (m): Classified by height (e.g., low slope <10m, medium slope 10-30m, high slope >30m); Climate conditions: Record factors that affect vegetation growth, such as regional climate type, annual precipitation, and extreme temperatures; Regional Soil: Determine soil type (e.g., typical mining soils such as granite residual soil and limestone soil), soil fertility, and degree of soil erosion; Mining infrastructure: Identify the type of mine (e.g., granite mine for construction, limestone mine, kaolin mine), geological hazard risk points, and the planned utilization type of the mine (e.g., ecological agriculture, municipal park, cultural tourism development, municipal facilities).

[0029] Preferably, the evaluation indicators include 11 indicators in total, such as lithology, slope, height, regional soil, geological disaster risk, time to effectiveness, greening effect requirements, durability, maintenance and management requirements, input cost and plant adaptability.

[0030] Based on the aforementioned land infrastructure information and regional characteristic information, and combined with actual mine engineering data, a quantitative standard is established. Each of the aforementioned evaluation indicators is then quantified into a specific numerical value or level according to this standard, and recorded as the engineering demand value. The subscript i indicates the evaluation index.

[0031] It should be noted that the aforementioned engineering requirements... Used to characterize the greening project needs of the target area, representing the demand side.

[0032] Preferably, the revegetation technology includes 17 revegetation technologies, such as the floating platform planting trough method, the terrace planting method, the bird's nest method, the grid beam method, the planting pot (trough) method, the planting bag method, the hanging cage brick method, the hole planting method, the broadcasting method, the turf greening method, the hydraulic spraying method, the topsoil spraying method, the three-dimensional net spraying method, the spray-mixed planting method, and the newly added geocell method, the thick substrate spraying method, and the vertical greening method of vine plants.

[0033] A pre-built historical revegetation project database is invoked, which is constructed based on case data from several historical revegetation projects. Based on the actual mine engineering data recorded in the historical revegetation project database, the technical suitability values ​​of the aforementioned 17 revegetation technologies on the aforementioned 11 evaluation indicators are quantified. The subscript i represents the evaluation index, and j represents the revegetation technology.

[0034] The requirement states that the technology adaptability value is used to characterize the technical capabilities that each revegetation technology can provide for each evaluation indicator, representing the supply side.

[0035] Furthermore, by combining the engineering requirement value and the technology adaptation value of all the evaluation indicators, the multi-indicator comprehensive matching degree of each of the greening technologies is calculated. The multi-indicator comprehensive matching degree is used to characterize the degree of matching of the greening technology in the target area based on the comprehensive consideration of multi-dimensional evaluation indicators. The higher the multi-indicator comprehensive matching degree, the higher the degree of matching.

[0036] Finally, it is determined whether there is a single revegetation technique whose overall matching degree across the multiple indicators is greater than or equal to a preset threshold. The preset threshold is set according to the actual situation, for example, 85%.

[0037] If a single revegetation technology meets the matching requirements, then that single revegetation technology is taken as the target revegetation technology, and a collaborative matching system between the revegetation technology and the plant configuration scheme is established in advance. Based on the target revegetation technology and the types of plants suitable for planting according to the regional characteristics of the target area, the plant configuration scheme matching the target revegetation technology is determined, and the single revegetation technology and its matching plant configuration scheme are output as the revegetation scheme for the target area.

[0038] If no single revegetation technology meets the matching requirements, a combined revegetation technology consisting of at least two revegetation technologies is generated according to the preset combination technology matching principle. The combined revegetation technology is taken as the target revegetation technology, and the corresponding plant configuration scheme is determined. The combined revegetation technology and its corresponding plant configuration scheme are output as the revegetation scheme for the target area.

[0039] By employing the technical means of this invention, a multi-dimensional, quantitative evaluation index system tailored to the regional characteristics of the target area's mines is constructed based on the land infrastructure and regional characteristics of the target region. This system integrates 11 evaluation indicators across six categories: slope characteristics, regional characteristics, geological hazard risk, ecological effects, economic costs, and plant adaptability, achieving comprehensive coverage and addressing the issue of incomplete regional adaptability. Furthermore, by combining actual mine engineering data as a quantitative basis, the system calculates the comprehensive matching degree of each revegetation technology across multiple indicators by quantifying the engineering requirements of these indicators and the technical adaptability of each revegetation technology to these indicators. This effectively establishes a quantitative matching model between evaluation indicators and revegetation technologies, improving the accuracy and efficiency of selecting revegetation technologies for the target area and eliminating the subjective influence of human experience. Moreover, in the absence of a single revegetation technology that meets the matching conditions, combined revegetation technologies are generated based on the principle of combining technologies, improving the selection guidance for combined technologies, clarifying the principles and quantitative standards for combining technologies in different scenarios, and enhancing the revegetation effect on complex mine slopes.

[0040] As an optional implementation, if the engineering requirement value ranges from 1 to 3 points, then the quantitative standards for the evaluation indicators include: Lithology: Hard rock or granite is 3 points, soft rock is 2 points, and soil is 1 point; Weathering degree: Strong weathering is 3 points, moderate weathering is 2 points, and slight weathering is 1 point; Slope: Gentle slope less than 30° is 1 point, medium slope 30°-60° is 2 points, and steep slope 60°-90° is 3 points; Height: 1 point for low slopes less than 10m, 2 points for medium slopes 10-30m, and 3 points for high slopes greater than 30m; Regional soil: Granite residual soil is 3 points, limestone soil is 2 points, and ordinary soil is 1 point; Geological disaster risk: High risk is 3 points, medium risk is 2 points, and low risk is 1 point; Time to Results: 3 points for rapid demand (less than 3 months), 2 points for moderate demand (3-6 months), and 1 point for long-term demand (more than 6 months). Greening effect requirements: High requirement is 3 points, medium requirement is 2 points, and low requirement is 1 point; Durability: Long-term demand is scored 3 points, medium-term demand is scored 2 points, and short-term demand is scored 1 point; Maintenance and management requirements: Low demand is 1 point, medium demand is 2 points, and high demand is 3 points; Input cost: 1 point for low budget, 2 points for medium budget, and 3 points for high budget; Plant adaptability: 3 points for high demand, 2 points for medium demand, and 1 point for low demand.

[0041] The specific data is shown in Table 1: Table 1

[0042] As a preferred embodiment, the present invention is further implemented based on any of the above embodiments. Step S12, namely, calculating the technical suitability value of each revegetation technology on each of the evaluation indicators based on the historical revegetation project database, includes steps S121 to S123: S121. Obtain the historical greening project database; wherein, the database records case data of several historical greening project cases; S122. Based on all the case data, generate the performance distribution of each of the revegetation technologies on each of the evaluation indicators; S123. Based on the performance distribution, quantify the technical fit value of each revegetation technology on each of the evaluation indicators.

[0043] In this embodiment of the invention, data on completed mine greening projects are collected to construct a historical greening project database. The case data for each project comes from at least one of the following: completion acceptance report, long-term monitoring data, geological survey report, and project evaluation report.

[0044] The completion and acceptance report includes slope parameters, the revegetation technology used, the plant configuration plan and cost data. The long-term monitoring data includes vegetation survival rate, growth status, maintenance frequency and durability. The geological survey report includes lithology, slope, soil type and geological hazard situation. The project evaluation report includes landscape effect evaluation and ecological benefit analysis.

[0045] For each case, the actual performance of the technology on each indicator is recorded. All engineering cases are summarized to form the performance distribution data of each revegetation technology on each evaluation indicator. Using the same quantitative standard as the engineering requirements, the performance distribution data is quantified into a technology suitability value of 1 to 3 points, and the typical suitability level of the technology on each indicator is statistically analyzed.

[0046] Furthermore, embodiments of the present invention also match suitable plant configuration schemes for each revegetation technology based on the historical data, and establish a collaborative database of revegetation technology and plant configuration.

[0047] For example, taking South China as an example, the technical compatibility values ​​and plant configuration schemes of some revegetation technologies on some evaluation indicators are shown in Table 2: Table 2

[0048] By employing the technical means of this invention, the quantitative standards for the engineering requirements of each evaluation indicator and the quantitative standards for the technical compatibility of each revegetation technology are improved. At the same time, a native plant configuration scheme for the target area is provided to achieve synergistic matching between technology and plants, which is conducive to improving the accuracy and efficiency of selecting revegetation technologies and plant configuration schemes for the target area.

[0049] For a preferred embodiment, see Figure 2 This is a flowchart illustrating a method for generating a revegetation scheme for a mining area, provided by an embodiment of the present invention. This embodiment further implements the above-described embodiments. Step S13, namely, calculating the multi-index comprehensive matching degree of each revegetation technology by integrating the engineering requirement value and the technology adaptation value of all the evaluation indicators, includes steps S131 to S133: S131. Obtain the regional correction coefficient for each of the revegetation technologies and the weighting coefficient for each of the evaluation indicators; wherein the regional correction coefficient is set according to the actual application rate of the revegetation technology in the mines in the target area; S132. Based on the engineering requirement value, the technology adaptation value and the regional correction coefficient, calculate the single-index adaptation degree of each of the greening technologies under each of the evaluation indicators. S133. Calculate the multi-indicator comprehensive matching degree of each of the above-mentioned greening technologies based on the weighting coefficients and the single-indicator fit degree.

[0050] In this embodiment of the invention, the single-index fit degree is used to characterize the degree of supply and demand matching reflected by the revegetation technology on the evaluation index. Adopting the principle of "minimizing index difference," and combining the regional correction coefficient applicable to the mines in the target area, the single-index fit degree of each technology and engineering requirement is calculated. The result ranges from 0 to 1, with a better fit being closer to 1.

[0051] The regional correction coefficient is set based on the actual application rate of the revegetation technology in the mines within the target area. Taking South China as an example, the application rate of the floating planting trough method is 76%, with a correction coefficient of 1.1; the application rate of the broadcasting method on steep slopes in South China is low, with a correction coefficient of 0.8.

[0052] Preferably, the formula for calculating the single-index fit is:

[0053] in, For the single-index fit of the j-th revegetation technology on the i-th evaluation index, Let j be the technology fit value of the i-th revegetation technology on the i-th evaluation index. Let i be the engineering requirement value for the i-th evaluation index. is the regional correction coefficient for the j-th revegetation technology.

[0054] For example, if the lithology of the target area is granite hard rock, the engineering requirement value is 3 points, the floating platform planting trough method is selected, the technical adaptation value of the lithology is 3 points, the regional correction coefficient is 1.1, then the single index adaptation degree of lithology = [1-|3-3| / 2]×1.1=1.1, which is corrected to the maximum value of 1.0.

[0055] Furthermore, a weighting coefficient for each of the aforementioned evaluation indicators is predetermined. Based on these weighting coefficients, the comprehensive matching degree of all revegetation technologies is calculated. The comprehensive matching degree ranges from 0 to 1. The formula for calculating the comprehensive matching degree of the multiple indicators is as follows:

[0056] in, The comprehensive matching degree of multiple indicators for the j-th revegetation technology, Let be the weight coefficient of the i-th evaluation indicator, and n be the total number of evaluation indicators.

[0057] In a preferred embodiment, obtaining the weight coefficient for each of the evaluation indicators includes: Based on the revegetation needs and planned utilization types of the target area, the weight coefficient of each evaluation indicator is determined.

[0058] Preferably, determining the weighting coefficient of each evaluation indicator based on the revegetation needs and planned utilization type of the target area includes: Based on the revegetation needs of the target area, the basic weight coefficient of each evaluation indicator is determined using the analytic hierarchy process. The basic weight coefficients are dynamically adjusted according to the planning and utilization type of the target area to obtain the final weight coefficient of each evaluation indicator.

[0059] In this embodiment of the invention, the Analytic Hierarchy Process (AHP) is used to determine the weights of each indicator. Basic weights are set based on the core needs of the mine revegetation project, and can be dynamically adjusted according to the mine's planned utilization type to ensure alignment with actual project priorities. Optionally, the adjustment range is ±0.05.

[0060] For example, taking South China as an example, the weighting coefficients of each of the aforementioned evaluation indicators are shown in Table 3: Table 3

[0061] The following is an example of adjusting the weight of mine utilization type: Cultural tourism development type: landscape effect (0.15), plant compatibility (0.10), time to see results (0.10); Ecological agriculture type: sustainability (0.18), geological disaster risk (0.15), regional soil (0.07); Municipal facilities type: input cost (0.05), maintenance and management requirements (0.05), lithology (0.22).

[0062] As a preferred embodiment, the present invention is further implemented based on any of the above embodiments, wherein generating a combined greening technology consisting of at least two greening technologies according to a preset combination technology matching principle includes: The revegetation technologies are sorted in descending order of their comprehensive matching degree among the multiple indicators; The top k revegetation technologies are selected as candidate revegetation technologies; where k ≥ 1. Based on the preset combination technology matching principles, at least one other revegetation technology that matches the candidate revegetation technology is determined to form a candidate combination revegetation technology; wherein, the combination technology matching principles include at least one of the following: complementary adaptation principle, regional adaptation principle, and cost controllable principle; Feasibility verification is performed on each of the candidate combination revegetation technologies, and the candidate combination revegetation technologies that pass the verification are obtained as the final combination revegetation technologies.

[0063] It should be noted that the complementary and adaptable principle refers to the principle that one technology in the combination compensates for the shortcomings of another technology, such as the grid beam method (structural protection) + sprayed vegetation method (ecological restoration); the regional adaptability principle refers to prioritizing the combination type that is maturely applied in the mines of the target area, such as the platform + bird's nest, geocell + stepped platform, platform + planters; the cost controllable principle refers to the principle that the total cost of the combined technologies does not exceed a preset multiple of the single high-cost technology, such as 1.5 times, to avoid excessive cost accumulation.

[0064] The feasibility verification dimensions include: construction compatibility (e.g., mechanized construction conditions in South China mines), cost superposition rationality (e.g., total cost not exceeding 1.5 times), ecological effect synergy (e.g., plant community adaptability to South China climate), and geological disaster protection (e.g., conformity to South China slope risk types).

[0065] By employing the technical means of this invention, the weights of indicators are dynamically adjusted according to the revegetation needs of the target area and the planned utilization type of the mine, adapting to different project priorities. A regional correction coefficient is introduced based on the actual application rate of the technology to optimize the calculation of single-indicator suitability and improve the accuracy of selection. Through a step-by-step process of single-indicator calculation, comprehensive matching degree analysis, and combined scheme generation, combined with the principle of technology matching, the accuracy and efficiency of technology selection are achieved.

[0066] This invention provides a standardized technology selection process, including indicator detection, weight allocation, adaptation calculation, and scheme optimization, ensuring that the selection process is scientific and replicable. A feasibility verification system for combined schemes is established from four dimensions: construction compatibility, cost aggregation, ecological synergy, and geological protection, ensuring that the schemes are suitable for actual mine construction.

[0067] See Figure 3 This is a schematic diagram of a device for generating a revegetation plan for a mining area according to an embodiment of the present invention. The embodiment of the present invention also provides a device 10 for generating a revegetation plan for a mining area, comprising: The engineering demand value calculation module 11 is used to collect land basic information and regional characteristic information of the target area, and convert them into engineering demand values ​​of preset multi-dimensional evaluation indicators according to preset quantitative standards. The technology adaptation value calculation module 12 is used to calculate the technology adaptation value of each greening technology on each of the evaluation indicators based on the historical greening project database. The comprehensive matching degree calculation module 13 is used to calculate the multi-index comprehensive matching degree of each of the greening technologies by comprehensively considering the engineering requirement value and the technology adaptation value of all the evaluation indicators.
