Abstract
Description
Technical Field
[0001] This application relates to the field of mining engineering technology, and in particular to a method, apparatus, and storage medium for determining the relocation distance of a crushing station. Background Technology
[0002] Crushing plant relocation is one of the core technologies of semi-continuous mining. The relocation distance directly affects the effectiveness of semi-continuous mining. The purpose of crushing plant relocation is to reduce truck transport distance and lower transportation costs. Currently, the relocation cost compensation method is used to determine the relocation distance of the crushing plant. This method optimizes the relocation distance by minimizing the sum of relocation costs and transportation costs through economic balance. However, it only focuses on the relocation cost of the crushing plant itself and the truck transportation cost, ignoring the dynamic factors of other subsequent process links that are closely coupled with it.
[0003] Research has revealed that semi-continuous mining technology relies on close coordination and capacity matching among its various stages to enable intermittent mining and continuous transportation systems to work in synergy, thereby improving the overall efficiency of the mining system. Currently, the relocation cost compensation method, in an effort to ensure economic balance and reduce the number of relocations, employs excessively long step distances. This results in slow updates to the crushing station's location, changes in the relative positions of the crushing station and the spoil heap, and ultimately, the spoil heap's position preceding the crushing station's. This undermines the system synergy of the semi-continuous process and increases transportation costs. Summary of the Invention
[0004] This invention provides a method, apparatus, and storage medium for determining the relocation distance of a crushing plant, to at least address the problems of disrupting the synergy of semi-continuous data collection processes and increasing transportation costs. The technical solution of this invention is as follows: According to a first aspect of the present invention, a method for determining the relocation distance of a crushing station is provided. The method includes: determining multiple candidate relocation years based on the relative positions of the crushing station and the spoil heap; the candidate relocation years representing the years in which the relocation operation of the crushing station is performed; determining multiple candidate remaining economic values associated with each candidate relocation year; the candidate remaining economic value representing the difference between the economic value generated within the cumulative service years and the relocation cost of the crushing station; selecting the target remaining economic value with the largest remaining economic value from the multiple candidate remaining economic values, and determining the candidate relocation year associated with the target remaining economic value as the target relocation year; and determining the target relocation distance of the crushing station according to the target relocation year and the annual progress of the open-pit coal mine working face corresponding to the crushing station.
[0005] As one implementation method, based on the relative positions of the crushing station and the dumping machine, multiple candidate relocation years are determined, including: the relative positions of the crushing station and the dumping machine always satisfy the condition that the dumping machine is located behind the crushing station; the initial distance between the crushing station and the dumping machine is determined; the cumulative annual tracking distance of the dumping machine within the preset relocation year is determined to be equal to the initial distance, and the preset relocation year is determined as the boundary year; multiple candidate relocation years are determined from the last relocation of the crushing station to the boundary year.
[0006] In this implementation, the spoil disposal machine is always positioned behind the crushing station to ensure the synergy of the semi-continuous mining process. Based on the relative position constraints, the boundary year for the relocation of the crushing station can be determined, thereby accurately identifying multiple candidate years, narrowing the range of candidate relocation years, and improving the efficiency of determining the relocation step distance.
[0007] As one implementation method, the service life represents the cumulative service life of the crushing station between the candidate relocation period and the last relocation of the crushing station.
[0008] Determine multiple candidate residual economic values associated with each candidate relocation period, including: based on the years of service, determine multiple candidate residual economic values corresponding to multiple candidate relocation periods according to the functional difference between the sum of the economic benefits generated from transportation between the crushing plant and the spoil heap and the economic benefits generated from transportation at the spoil heap working face corresponding to the spoil heap, and the cost of relocating the crushing plant.
[0009] In this implementation, the economic value of transporting waste material by belt conveyor at the crushing plant is determined based on the annual material volume required, compared to transporting waste material by truck. This fully considers the dynamic factors of the crushing plant and the dumping machine, ensuring the accuracy of determining the remaining economic value.
[0010] As one implementation method, the candidate residual economic value is represented by the following formula: Where i represents the relocation period as the i-th year; Represents residual economic value; This is the initial length of the end-belt conveyor; The annual tracking distance for the spoil heap; For truck unit transportation costs; The unit transportation cost of the belt conveyor; The amount of material served by the crushing station in year i; The length of the working face of the spoil heap; Costs for relocating the crushing station.
[0011] As one implementation method, determining the non-transferable years specifically includes: selecting loss-making economic values with negative residual economic values from multiple candidate residual economic values, and determining the candidate transferable years associated with the loss-making economic values as non-transferable years.
[0012] In this implementation, when the remaining economic value is negative, meaning the relocation cost of the crushing station exceeds the economic value generated during the station's service life, relocating the crushing station within that candidate relocation period would result in a loss. Unrelocatable periods are eliminated from multiple candidate relocation periods to ensure the rationality of determining the relocation step size based on economic costs.
[0013] As one approach, multiple candidate relocation years are determined to have equal remaining economic values, and the candidate relocation year with the longest term is selected as the target relocation year.
[0014] In this embodiment, the candidate relocation period with a longer term corresponds to a longer relocation step. When the remaining economic value corresponding to multiple candidate relocation periods is the same, selecting the candidate relocation period with a longer term can effectively reduce the overall number of relocations and save the overall relocation cost in the open-pit coal mining process.
[0015] As one implementation method, the target relocation step distance of the crushing station is determined based on the target relocation year and the annual progress of the open-pit coal mine working face corresponding to the crushing station. This includes: the relocated position of the crushing station is close to the open-pit coal mine working face corresponding to the crushing station; the target relocation step distance of the crushing station is obtained based on the cumulative value of the annual progress of each year between the last relocation year of the crushing station and the target relocation year.
[0016] In this implementation, the crushing station is relocated at the target relocation date. The station is moved from its previous location to the location of the open-pit coal mine working face at the target relocation date; this distance is the relocation step distance. Taking full account of the synergy of each stage in the semi-continuous process, and based on the relative positions of the crushing station and the spoil heap, the most reasonable and economically valuable relocation step distance is determined from an economic cost perspective.
[0017] As one implementation method, the terrain conditions of the location after the relocation of the crushing station are determined based on the target relocation step distance of the crushing station; the terrain conditions are checked to ensure they meet the preset terrain requirements, and the relocation of the crushing station and the spoil heap is carried out; the preset terrain requirements include foundation bearing capacity, slope stability, and flatness requirements.
[0018] In this embodiment, the terrain stability of the relocation site of the crushing station is guaranteed, and the stability of the terrain where the crushing station is located is guaranteed within the preset service life. This avoids the need to relocate the crushing station due to terrain collapse, thus saving the cost of relocating the crushing station.
[0019] According to a second aspect of the present invention, a device for determining the relocation distance of a crushing station is provided, the device comprising: The relocation period determination unit is configured to determine multiple candidate relocation periods based on the relative positions of the crushing station and the spoil heap; the candidate relocation period represents the year in which the relocation operation of the crushing station is performed; multiple candidate residual economic values associated with each candidate relocation period are determined; the candidate residual economic value represents the difference between the economic value generated within the cumulative service years and the relocation cost of the crushing station; from the multiple candidate residual economic values, the target residual economic value with the largest residual economic value is selected, and the candidate relocation period associated with the target residual economic value is determined as the target relocation period.
[0020] The relocation step distance determination unit is configured to determine the target relocation step distance of the crushing station based on the target relocation year and the annual advance of the open-pit coal mine working face corresponding to the crushing station.
[0021] According to a third aspect of the present invention, a crushing plant relocation step distance determination device is provided, the device being configured to perform a crushing plant relocation step distance determination method as described in the first aspect and any possible implementation thereof.
[0022] According to a fourth aspect of the present invention, a computer-readable storage medium is provided, on which instructions are stored, such that when the instructions in the computer-readable storage medium are executed by a processor of a crushing station relocation step distance determination device, the crushing station relocation step distance determination device is able to perform a crushing station relocation step distance determination method as described in the first aspect and any possible implementation thereof.
[0023] According to a fifth aspect of the present disclosure, a computer program product is provided, the computer program product including computer instructions, which, when executed on a crushing station relocation step distance determining device, cause the crushing station relocation step distance determining device to perform the crushing station relocation step distance determining method of the first aspect and any possible implementation thereof.
[0024] The technical solutions provided by the embodiments of the present invention bring at least the following beneficial effects: This application fully considers the dynamic factors of each link in the mining process. Before the relocation of the crushing station, the location of the crushing station remains unchanged. The working face of the open-pit coal mine advances according to the annual progress, and the location of the dumping machine moves closer to the crushing machine according to the annual tracking distance. In order to ensure the system synergy of the semi-continuous process of open-pit coal mining, the relative positions of the crushing station and the dumping machine must be guaranteed. In the year when the positions of the dumping machine and the crushing station are consistent, the crushing station must be relocated. Based on this, multiple candidate relocation years are determined. By determining that after the relocation operation is performed on the crushing station in the candidate relocation years, the economic value generated by the crushing station within its service years can fully cover the cost of relocating the crushing station, that is, the remaining economic value generated by the crushing station within its service years after relocation, the candidate relocation year corresponding to the highest remaining economic value is determined as the target relocation year. The relocation operation is then performed on the crushing station in the target relocation year, and the relocation step distance of the crushing station is determined according to the annual progress of the open-pit coal mine working face. Therefore, the above method for determining the relocation distance of the crushing station fully considers the influence of the relative positions of the crushing station and the dumping machine in the semi-continuous mining process. By analyzing the remaining economic value corresponding to different relocation years, the relocation distance of the crushing station can be determined more reasonably, thereby reducing the truck haul distance and saving transportation costs.

Detailed Implementation
[0028] To enable those skilled in the art to better understand the technical solutions of this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings.
[0029] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.
[0030] Before providing a detailed description of the method for determining the relocation distance of the crushing station provided in this application embodiment, let's briefly introduce the application scenarios and implementation environment involved in this application embodiment.
[0031] Research has revealed that the relocation of crushing stations is one of the core technical issues in semi-continuous mining. The relocation distance directly affects the effectiveness of the semi-continuous mining process, and the purpose of relocation is to reduce truck haulage distance and lower transportation costs. In open-pit mines, a common method for calculating the relocation distance of crushing stations is the relocation cost compensation method. The core of this method is to determine the optimal relocation scheme that minimizes the sum of relocation costs and transportation costs through economic balance. However, this method only considers factors related to the crushing station when calculating the relocation distance, neglecting other dynamic factors, such as changes in truck haulage distance and the relocation of the dumping machine. The relocation cost compensation method only considers the relocation of the crushing station and does not account for changes in the relative positions of the crushing station and the dumping machine. When the relocation period is too long, the dumping machine may appear to be ahead of the crushing station, leading to backhauling, disrupting the system synergy of the semi-continuous process, increasing haulage distance, and raising transportation costs.
[0032] To address the aforementioned issues, this application proposes a method for determining the relocation distance of a crushing station. To ensure the system synergy of the semi-continuous process in open-pit coal mining, the relative positions of the crushing station and the dumping machine must be maintained. In years when the dumping machine and the crushing station are in the same position, the crushing station must be relocated. Based on this, multiple candidate relocation years are determined. By determining that the economic value generated by the crushing station within its service life after relocation within a candidate relocation year can fully cover the cost of relocating the crushing station (i.e., the remaining economic value generated within its service life after relocation), the candidate relocation year corresponding to the highest remaining economic value is determined as the target relocation year. The relocation operation is then performed on the crushing station within the target relocation year, and the relocation distance is determined based on the annual advancement of the open-pit coal face. Therefore, this method fully considers the influence of the relative positions of the crushing station and the dumping machine in the semi-continuous mining process. By analyzing the remaining economic value corresponding to different relocation years, the relocation distance of the crushing station can be determined more rationally, thereby reducing truck transport distance and saving transportation costs.
[0033] Secondly, the implementation architecture involved in this application will be briefly introduced below.
[0034] Figure 1 This is a schematic diagram of a crushing plant relocation step distance determination system provided in this application. Figure 1 As shown, the system for determining the relocation distance of the crushing station includes a life analysis module 11, a remaining economic value analysis module 12, a relocation life determination module 13, and a relocation distance determination module 14.
[0035] The aforementioned time limit analysis module 11, residual economic value analysis module 12, relocation time limit determination module 13, and relocation step distance determination module 14 are connected by communication.
[0036] The age analysis module 11 is configured to determine multiple candidate relocation ages based on the relative positions of the crushing station and the dumping machine.
[0037] The residual economic value analysis module 12 is configured to determine multiple candidate residual economic values associated with each candidate relocation period.
[0038] The relocation period determination module 13 is configured to select the target residual economic value with the largest residual economic value from multiple candidate residual economic values, and determine the candidate relocation period associated with the target residual economic value as the target relocation period.
[0039] The relocation step distance determination module 14 is configured to determine the target relocation step distance of the crushing station based on the target relocation year and the annual advance of the open-pit coal mine working face corresponding to the crushing station.
[0040] For ease of understanding, the following section provides a detailed description of the in-use oil selection method provided in this application, in conjunction with the accompanying drawings.
[0041] Figure 2 This is a flowchart illustrating a method for determining the relocation step distance of a crushing station according to an exemplary embodiment, such as... Figure 2 As shown, the method for determining the relocation distance of the crushing station includes the following steps.
[0042] S21. Based on the relative positions of the crushing station and the spoil disposal machine, multiple candidate relocation years are determined.
[0043] The candidate relocation year represents the year in which the relocation operation of the crushing station is carried out.
[0044] The relocation period for the next relocation is recalculated after each relocation of the crushing plant.
[0045] In the semi-continuous process of open-pit coal mines, the initial location of the crushing station is at the same position as its corresponding open-pit coal face. The dumper is located behind the crushing station, and the distance between the belt conveyors is determined based on the initial distance between the dumper and the crushing station. After mining operations begin, the location of the crushing station remains fixed until it is relocated. The working face advances according to the annual progress rate, and this annual progress rate is used as the annual tracking distance of the dumper to move closer to the crushing station. Consequently, the distance of the belt conveyors decreases year by year.
[0046] In one implementation, the candidate relocation period in step S21 is determined through the following specific steps.
[0047] First, the relative positions of the crushing plant and the dumping machine must always ensure that the dumping machine is behind the crushing plant. The initial distance between the crushing plant and the dumping machine is determined, and the cumulative annual tracking distance of the dumping machine within the preset relocation period is determined to be equal to the initial distance. The preset relocation period is then defined as the boundary period.
[0048] To ensure the synergy of the semi-continuous process, the relative positions of the crushing station and the spoil disposal machine must be maintained, ensuring that the spoil disposal machine is always positioned behind the crushing station. The spoil disposal machine tracks the distance towards the crushing station annually, and it is determined that the position of the spoil disposal machine will be level with the position of the crushing station by a preset relocation date. Therefore, the crushing station must be relocated before the preset relocation date, thus establishing the boundary year.
[0049] Secondly, several candidate relocation dates were determined between the last relocation of the crushing station and the boundary date.
[0050] Each time the crushing station is relocated, its position is aligned with the working face. Therefore, multiple candidate relocation years are determined between the last relocation of the crushing station and the boundary year, effectively narrowing down the range of candidate relocation years.
[0051] S22, determine the remaining economic value of multiple candidates associated with each candidate relocation period.
[0052] The candidate residual economic value represents the difference between the economic value generated within the cumulative years of service and the cost of relocating the crushing station.
[0053] Service life represents the cumulative service life of the crushing station between the candidate relocation date and the last relocation date.
[0054] The transportation distance for waste materials includes the transportation distance between the crushing station and the dumping machine, as well as the lateral distance of the dumping site.
[0055] In one method for determining candidate residual economic value, based on the years of service, multiple candidate residual economic values corresponding to multiple candidate relocation years are determined by the functional difference between the sum of the economic benefits generated from transportation between the crushing plant and the spoil heap and the economic benefits generated from transportation at the spoil heap working face corresponding to the spoil heap and the cost of relocating the crushing plant.
[0056] The residual economic value is the difference between the economic value generated by using the belt conveyor of the crushing plant to transport waste materials during the service years after the relocation of the crushing plant and the cost of relocating the crushing plant during that period.
[0057] The economic value of transporting waste materials by belt conveyors in a crushing plant is characterized by the economic value of transporting waste materials from the crushing plant to the dump machine and the dump site working face by belt conveyors compared to the economic value of transporting waste materials by trucks.
[0058] In this method for determining the remaining economic value of candidates, the annual material volume required is used as the basis for determining the remaining economic value. The method identifies the economic value generated by adding a belt conveyor to the crushing station in a semi-continuous process to transport waste material from the crushing station to the spoil heap and the waste material at the spoil heap working face, compared to simply transporting waste material by truck. A thorough analysis of the dynamic factors of the crushing station and the spoil heap ensures the accuracy of the remaining economic value. This method determines the remaining economic value corresponding to each candidate relocation year, providing accurate data support for subsequently determining the target relocation year based on the magnitude of the corresponding remaining economic value.
[0059] In one implementation, the candidate residual economic value is specifically represented by the following formula (1): (1).
[0060] Where i represents the relocation period as the i-th year; Represents residual economic value; This is the initial length of the end-belt conveyor; The annual tracking distance for the spoil heap; For truck unit transportation costs; The unit transportation cost of the belt conveyor; The amount of material served by the crushing station in year i; The length of the working face of the spoil heap; Costs for relocating the crushing station.
[0061] The diagram showing the location and distance between the crushing plant and the spoil heap is as follows: Figure 3 As shown.
[0062] Understandably, determining the remaining economic value generated within the service life of the crushing plant after relocation requires full consideration of the dynamic factors of both the crushing plant and the spoil heap. If the crushing plant is relocated within the candidate relocation period, it will generate full economic value at the beginning of the year, but by the end of the year, its economic value will be close to zero. Furthermore, considering the length of the spoil heap's working face, the crushing plant's belt conveyor can transport materials from the spoil heap's working face close to the conveyor, but not at the end of the working face. Therefore, considering the timing and location where the crushing plant cannot generate economic value is crucial for more accurately determining the remaining economic value generated after relocation within the candidate relocation period, ensuring a more reasonable relocation step based on the relocation period.
[0063] S23, select the target residual economic value with the largest residual economic value from multiple candidate residual economic values, and determine the candidate relocation period associated with the target residual economic value as the target relocation period.
[0064] By accurately comparing the remaining economic values corresponding to different candidate relocation years, the optimal target relocation year that maximizes economic value can be proactively identified and determined. This ensures that after the crushing station is relocated, the economic value generated within its service life can effectively cover and far exceed its relocation costs, thereby maximizing economic benefits and guaranteeing the rationality of determining the relocation step size based on the relocation year.
[0065] Optionally, from multiple candidate residual economic values, loss-making economic values with negative residual economic values are selected, and the candidate relocation years associated with the loss-making economic values are determined as non-relocation years.
[0066] If, after relocating the crushing station within the candidate relocation period, the economic value generated by the station's existing service years is insufficient to cover the relocation costs, it indicates that the relocation costs within that candidate relocation period exceed the economic value generated by the station, resulting in a loss. The candidate relocation period corresponding to the loss-making economic value is designated as an unrelocatable period, thereby eliminating unrelocatable periods from the candidate relocation period and ensuring the rationality of the subsequent confirmation of the target relocation period.
[0067] Optionally, multiple candidate residual economic values corresponding to multiple candidate relocation years are determined to be equal, and the candidate relocation year with the longest term is determined as the target relocation year.
[0068] In the entire open-pit coal mining operation, the longer the step distance of the crushing station relocation, the fewer the number of relocations required, thereby reducing the relocation cost of the entire mining operation.
[0069] The working face of an open-pit coal mine advances annually according to the annual progress, and the location of the relocated crushing station is consistent with the location of the working face at the preset relocation date. Therefore, when there are multiple candidate relocation dates with equal remaining economic value, the candidate date with the longer relocation date is selected as the target relocation date. The longer the corresponding relocation step, the more effectively the cost of relocating the crushing station can be saved in mining operations.
[0070] S24. Determine the target relocation step distance of the crushing station based on the target relocation year and the annual progress of the open-pit coal mine working face corresponding to the crushing station.
[0071] In one method for determining the target relocation step distance, the relocated position of the crushing station is close to the open-pit coal mine working face corresponding to the crushing station. The target relocation step distance of the crushing station is obtained based on the cumulative value of the annual progress in each year between the last relocation year of the crushing station and the target relocation year.
[0072] In the above method for determining the target relocation step distance, the crushing station is relocated at the target relocation year. The crushing station is moved from its previous relocation position to the position of the open-pit coal mine working face at the target relocation year; this distance is the relocation step distance of the crushing station. Therefore, the target relocation step distance of the crushing station is obtained by determining the cumulative annual advancement of the open-pit coal mine working face between the target relocation year and the previous relocation year.
[0073] By comparing the remaining economic value corresponding to different relocation years, the relocation year with the highest remaining economic value is determined. Then, by considering the relocation year and the advancement of the open-pit coal mine face, the corresponding relocation step distance is determined. This fully considers the synergy of various links in the semi-continuous process and, based on the relative positions of the crushing station and the spoil heap, determines the most reasonable and economically valuable relocation step distance from an economic cost perspective.
[0074] Optionally, based on the target relocation step distance of the crushing station, the terrain conditions of the relocated location of the crushing station are determined; if the terrain conditions meet the preset terrain requirements, the crushing station and the spoil heap are relocated; the preset terrain requirements include foundation bearing capacity, slope stability, and flatness requirements.
[0075] For example, the terrain conditions at the new relocation site of a crushing plant with a crushing capacity of 9000 h / t must meet the following requirements: the foundation bearing capacity must distinguish between static and dynamic loads. Static loads include the self-weight of the crushing plant and the weight of the material at full load, ranging from 6500 to 7500 t; the foundation for dynamic loads must withstand local peak pressures ≥ 400 kPa; the slope stability coefficient Fs ≥ 1.3, and the distance between the edge of the crushing plant and the top of the spoil heap slope must be ≥ 1.5 times the slope height; the overall foundation platform slope ≤ 3%.
[0076] Therefore, it is essential to ensure the stability of the terrain at the relocation site of the crushing plant, guarantee the stability of the terrain where the crushing plant is located within the preset service life, avoid the need to relocate the crushing plant due to terrain collapse, and save on the cost of relocation.
[0077] To achieve the above functions, the crushing station relocation step distance determination device includes hardware structures and / or software modules corresponding to the execution of each function.
