[0002] In the field of mining, reasonable mining layout is crucial to improving mining efficiency and ensuring mining safety. However, the existing technology has some shortcomings in mining layout. The traditional mining layout method often lacks accurate consideration of the thickness, morphological characteristics and distribution characteristics of the ore body, resulting in unreasonable layout of adjacent layered mine rooms and cross-connected tunnels, which cannot fully adapt to the actual situation of the ore body. This not only affects the mining efficiency, but also may increase the safety risks in the mining process, such as roof collapse, ore loss and other problems. In addition, the existing technology also has shortcomings in the configuration and layout optimization of mining equipment.

[0016] The present application provides a mining area layout optimization method, equipment and medium, which are used to solve the technical problems of lack of rationality and safety of mining layout and low mining efficiency in the prior art.

[0017] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] Embodiment 1, as Figure 1 As shown, the present application provides a method for optimizing the layout of a mining area, the method comprising:

[0019] Step S100: Detect the ore body thickness data of the target mining area, and divide the layout according to a type of combined layout method defined by adjacent layered mine rooms, wherein the type of combined layout method defined by adjacent layered mine rooms includes a vertical layout method, an oblique layout method, and a layout method along the ore body strike.

[0020] Specifically, the detection of ore body thickness data in the target mining area is a crucial basic work. First, by using professional measurement equipment and technology, multiple representative points are selected in the target mining area to collect ore body thickness information. These collected data reflect the changes in ore body thickness at different locations, providing the original basis for subsequent analysis and layout design. After the collection is completed, these scattered point data are converted into an intuitive three-dimensional model of ore body thickness using 3D modeling software. Such a model can more clearly present the spatial distribution characteristics of ore body thickness. On the basis of obtaining ore body thickness data, layout division begins. Among them, there are multiple options for a type of combined layout method limited by adjacent layered mine rooms. If a vertical layout method is adopted, the adjacent layered mine rooms will be arranged in a direction perpendicular to the ore body strike. This method can effectively improve mining efficiency and resource recovery rate under certain specific ore body forms and geological conditions. The oblique layout method is to arrange the adjacent layered mine rooms at an oblique angle to the ore body strike. This method can be flexibly adjusted according to the inclination and complexity of the ore body to meet different mining needs. The layout method along the ore body strike is to arrange adjacent layered mine rooms along the strike of the ore body. When the ore body strikes regularly and the thickness is relatively stable, this method can simplify the mining project and reduce the construction difficulty and cost. By comprehensively considering the actual situation of the ore body, including thickness changes, geological structure, ore grade and other factors, the most appropriate type of combined layout method is selected to lay a good foundation for subsequent mining work.

[0021] Step S200: and, establishing an ore body geological space in the target mining area through a mining area ore body prediction map of the target mining area, wherein the ore body geological space includes ore body morphological characteristics and ore body distribution characteristics in the target mining area.

[0022] Specifically, the ore body prediction map of the target mining area plays a key role. First, with the help of professional GIS software, we start to create the geological framework of the ore body in the target mining area. This framework is like building a virtual space container to prepare for the subsequent accommodation and presentation of various ore body information. Based on the theory of geostatistics, we deeply analyze the spatial variability and continuity of the ore body in the ore body geological framework. Spatial variability refers to the characteristic differences of the ore body at different locations, such as changes in thickness, grade, etc.; continuity focuses on the continuity and extension trend of the ore body in space. Through these analyses, we can more accurately grasp the inherent laws of the ore body. For the morphological characteristics of the ore body, it includes the shape of the ore body, whether it is layered, veined, lens-shaped or other complex shapes; the size of the ore body, length, width, height and other dimensional information; and the boundary characteristics of the ore body, whether it is a clear and definite boundary or a gradually transitioning fuzzy boundary. The ore body distribution characteristics cover the spatial distribution of the ore body in the entire mining area, such as the directional information such as the strike, inclination, and inclination of the ore body, the density distribution of the ore body, whether it is concentrated or dispersed, etc. The ore body morphology and distribution characteristics obtained through analysis are expressed in a visual way based on the previously created ore body geological framework. For example, different colors, lines, symbols, etc. are used to clearly display them on the ore body prediction map of the mining area, so that the specific morphology and distribution of the ore body in the target mining area can be intuitively seen, thus providing extremely important information support and decision-making basis for subsequent mining planning, layout design, resource assessment and other work.

[0023] Step S300: performing initial layout optimization according to a type of combined layout mode defined by adjacent stratified mine rooms, adding M auxiliary lines in the ore body geological space, and determining the first single-layer layout position distribution structure of the adjacent stratified mine rooms.

[0024] Specifically, it should be made clear that a type of combined layout method includes vertical layout, oblique layout and layout along the ore body strike. The appropriate layout method should be selected according to the actual ore body conditions and mining needs. When entering the geological space of the ore body, in order to plan and design the layout more accurately, M auxiliary lines are added. These auxiliary lines play a key auxiliary planning role. By adjusting and optimizing the position, angle, length and other parameters of these auxiliary lines, the general outline and distribution situation of adjacent layered mine rooms can be gradually outlined. The ore body thickness data plays a vital role in this process. If the ore body thickness is large, it will tend to choose a vertical layout method. At this time, the layout of the auxiliary lines will be adjusted accordingly to adapt to the layout of the mine rooms in the vertical direction. For example, the auxiliary lines will be arranged in a direction perpendicular to the strike of the ore body to ensure that adjacent layered mine rooms can be staggered in the vertical direction to improve mining efficiency and resource recovery rate. If the thickness of the ore body is at a medium level, the oblique layout method is more appropriate. In this case, the auxiliary line will be at a certain oblique angle with the ore body trend. By accurately calculating and adjusting this angle, the adjacent layered mine rooms can be reasonably distributed in the oblique direction, which can fully utilize the ore body space and ensure the safety and stability of mining operations. When the thickness of the ore body is small, the layout method along the ore body trend will play an advantage. At this time, the auxiliary line will be arranged along the ore body trend to guide the adjacent layered mine rooms to be arranged along the ore body trend, ensuring that the ore resources can be mined to the greatest extent under the limited ore body thickness, while reducing the difficulty and cost of the mining project. By continuously adjusting and optimizing these auxiliary lines, combined with the analysis of different ore body thickness data, the first single-layer layout position distribution structure of adjacent layered mine rooms can be finally determined. This structure will serve as an important basis for further optimization and refinement of the mining layout, and provide strong support for the realization of efficient, safe and scientific mining operations.

[0025] Step S400: Add U safe operation exits, and divide the layout into two types of combined layouts defined by cross-connected lanes, wherein the two types of combined layouts defined by the cross-connected lanes include a tic-tac-toe layout, a ring layout, and a mesh layout, and U≥2.

[0026] Specifically, adding safe working exits is a key measure to ensure the safety of mining workers. Here, it is determined that U safe working exits are added, and U is greater than or equal to 2. This is to ensure that in an emergency, workers have enough escape routes. The setting of multiple safe exits can avoid dangerous situations caused by the obstruction of a single exit, greatly improving the safety of personnel underground. At the same time, for the layout division of cross-connected tunnels, two types of combined layout methods are adopted. Among them, the criss-cross layout method is to arrange the tunnels in a criss-cross manner. The advantage of this method is that it can connect various areas to each other, so that personnel and equipment can move quickly between different areas, facilitate the transportation and deployment of resources, and there are multiple evacuation routes to choose from in an emergency. The ring layout method is to arrange the tunnels into one or more ring structures. Such a layout makes the connection between tunnels smoother, reduces the return of personnel and equipment during transportation, and improves transportation efficiency. In an emergency, the ring tunnel also facilitates personnel to quickly evacuate to a safe area along the ring channel. The mesh layout method is to interweave the tunnels into a mesh-like structure. This layout has a high degree of connectivity, and the connection between each area is closer, which can better adapt to the complex ore body distribution and mining operation needs. Whether it is resource mining, transportation, or personnel passage, the mesh layout method can provide flexible and diverse path options. According to the actual geological conditions of the mining area, ore body distribution, operation needs, and safety requirements, it is reasonable to choose a tic-tac-toe, ring or mesh layout method, or combine them to achieve the optimal cross-connected tunnel layout effect, providing a solid foundation for the smooth progress of mining operations and the safety of personnel.

[0027] Step S500: performing secondary layout optimization according to the two types of combined layout methods defined by the cross-connected lanes, adding N auxiliary lines in the ore body geological space, and determining the second single-layer layout position distribution structure of the cross-connected lanes.

[0028] Specifically, secondary layout optimization is implemented based on the two-type combined layout methods defined by the cross-connected tunnels. First, different two-type combined layout methods are considered, such as tic-tac-toe, ring or mesh layout methods, each of which has its own unique characteristics and applicable scenarios. N auxiliary lines are added to the geological space of the ore body. These auxiliary lines play a vital role in the secondary layout optimization. They are like precise rulers and guide lines, helping to outline the layout outline of the cross-connected tunnels more clearly. The safe path length data is of key significance in this process. If the safe path length is short, the tic-tac-toe layout method will be preferred because it can achieve efficient connection in a relatively small area. The auxiliary lines can be arranged in a tic-tac-toe pattern, so that the cross-connected tunnels form a clear layout structure in a limited space, ensuring that personnel and equipment can be quickly moved and transported within a short distance. When the safe path length is moderate, the ring layout method is more appropriate. At this time, auxiliary lines will be added and adjusted around the circular path to ensure the smoothness and continuity of the circular cross-connected lanes, which not only meets the needs of the safe path, but also enables resources to flow efficiently in the circular channel. At the same time, in an emergency, personnel can be quickly evacuated along the circular path. For situations where the length of the safe path is long, the mesh layout may be more advantageous. N auxiliary lines will be distributed according to the characteristics of the mesh structure to form an interwoven and tightly connected network. Such a layout can ensure that personnel and equipment can reach their destination through multiple channels in a long-distance safe path, improving the overall transportation efficiency and safety. Through the careful arrangement and adjustment of N auxiliary lines, combined with in-depth analysis of the safe path length data, the second single-layer layout position distribution structure of the cross-connected lanes can be finally determined. This structure will further improve the layout of the mining area and provide a more solid foundation for the efficient conduct of mining operations and the safety of personnel.

[0029] Step S600: In the geological space of the ore body, the first single-layer layout position distribution structure is overlapped with the second single-layer layout position distribution structure, and the M auxiliary lines and the N auxiliary lines are adjusted in combination with the ore body thickness data, and the lower layered mine room corresponding to the adjacent layered mine room and the artificial false bottom corresponding to the cross-connected tunnel are reset.

[0030] Specifically, in the virtual three-dimensional scene of the ore body geological space, the key integration and adjustment operations are started. First, the first single-layer layout position distribution structure is overlapped with the second single-layer layout position distribution structure to comprehensively consider the relationship and influence between the two layout structures. The auxiliary lines are adjusted in combination with the crucial ore body thickness data, which reflects the scale and changes of the ore body in the vertical direction and has a profound impact on the entire mining layout. For the M auxiliary lines, these lines originally used to determine the first single-layer layout position distribution structure of adjacent layered mine rooms need to be re-examined and adjusted based on the new comprehensive information and changes in ore body thickness. For example, if the ore body thickness has changed significantly in some areas, the position and angle of the auxiliary lines need to be adjusted accordingly to ensure that the layout of adjacent layered mine rooms is more reasonable and can adapt to the new ore body conditions. For the N auxiliary lines, they played a key role in determining the second single-layer layout position distribution structure of the cross-connected roadway, and now they are also optimized based on the overlapped overall layout and ore body thickness data. For example, in areas with thick ore bodies, it is necessary to adjust the auxiliary lines to ensure smoother connections between cross-connected lanes and adjacent stratified mine rooms, and more efficient resource transportation and personnel traffic. After adjusting the auxiliary lines, the lower stratified mine rooms corresponding to adjacent stratified mine rooms and the artificial false bottom corresponding to the cross-connected lanes begin to be reset. The reset of the lower stratified mine room needs to fully consider the layout of the upper stratified mine room and the actual shape and thickness of the ore body. Through precise calculation and planning, it is ensured that the position, size and shape of the lower stratified mine room can maximize the use of ore body resources while ensuring the safety and stability of mining operations. For the artificial false bottom corresponding to the cross-connected lane, its reset should match the adjusted cross-connected lane layout. The artificial false bottom plays a supporting and protective role in the mining process. Its position and structure need to adapt to the new lane layout to ensure the stable operation of the entire mining system. Through these meticulous and precise adjustment and reset operations, the entire mining layout is made more scientific, reasonable and efficient, laying a solid foundation for subsequent mining operations.

[0031] Step S700: Based on the lower layered mine room corresponding to the reset adjacent layered mine room and the artificial false bottom corresponding to the cross-connected tunnel, the corresponding mining equipment is connected, the mining equipment configuration parameters are imported, and the mining efficiency is optimized based on the mining equipment configuration parameters to determine the optimal layout plan for the target mining area.

[0032] Specifically, with the reset of the lower stratum mine room and artificial false bottom, the next step is to closely connect with the mining equipment. First, according to the actual layout and structural characteristics of the lower stratum mine room and the cross-connected tunnels, the appropriate mining equipment is matched and connected with them. For example, for the mining equipment, it is necessary to ensure that it can smoothly enter the lower stratum mine room and the connection path with the transportation equipment is reasonable, so as to ensure the efficiency and smoothness of the entire process from mining to transportation of ore. Then, the configuration parameters of the mining equipment are imported, among which the working face length and the advancement direction are crucial parameters. The setting of the working face length directly affects the scope and efficiency of a mining operation. If the working face length is too long, it will increase the difficulty of equipment management and operation; if it is too short, it will reduce the mining efficiency and increase the frequency of equipment movement and adjustment. The advancement direction is related to the order and direction of the entire mining. Different advancement directions will have different effects on the ore recovery rate, roof management, ventilation and other aspects. When optimizing the mining efficiency with these mining equipment configuration parameters as limiting conditions, it is necessary to fully consider the relationship between various factors. For example, when the length of the working face is determined, the number and layout of the equipment need to be adjusted according to the production capacity and transportation capacity of the equipment to make full use of the working face and avoid idle or overloaded equipment. At the same time, the choice of advancement direction should be combined with factors such as the geological conditions of the ore body, the structure of the mine room, and ventilation requirements. If the advancement direction is unreasonable, it will lead to problems such as concentrated roof pressure and poor ventilation, thereby affecting mining efficiency and safety. In the optimization process, through continuous simulation and adjustment, different values ​​can be tried for the length of the working face to observe their impact on mining efficiency and cost and find an optimal balance point. For the advancement direction, multiple schemes can be compared and analyzed, such as starting from different directions to observe changes in ore recovery rate, equipment operation efficiency, and safety risks. After repeated simulation, verification, and adjustment, the layout plan of the target mining area that can achieve the best mining efficiency is finally determined. This plan fully considers the interaction and influence between the lower layer mine room, cross-connected tunnels, mining equipment, and various configuration parameters, providing reliable guidance for actual mining operations.

[0033] In a possible implementation, step S100 further includes:

[0034] Step S110: Collecting the ore body thickness at multiple points in the target mining area, obtaining the ore body thickness distribution and using three-dimensional modeling software to obtain a three-dimensional model of the ore body thickness.

[0035] Step S120: Based on the three-dimensional model of ore body thickness, a Kriging interpolation algorithm is used to fill in missing data to obtain complete ore body thickness data of the target mining area.

[0036] Specifically, we first conduct detailed measurements of the target mining area, select multiple representative points in the area, and accurately collect the thickness of the ore body at these points through professional measurement equipment and technical means. As the data collection of each point is completed, the distribution of the ore body thickness at different locations can be preliminarily obtained. Using advanced 3D modeling software, these scattered point thickness data are converted into an intuitive 3D model. In this model, the fluctuations and distribution trends of the ore body thickness in space can be clearly seen, providing an intuitive visual reference for subsequent analysis and processing.

[0037] Based on the constructed three-dimensional model of ore body thickness. Since there are some areas with missing data in the actual measurement process, the Kriging interpolation algorithm is used to solve this problem. The algorithm will reasonably estimate and fill in the areas with missing data based on the ore body thickness data of known points, as well as the spatial correlation and variation characteristics between these data. Through continuous calculation and adjustment, the missing data is supplemented, and finally the complete ore body thickness data of the target mining area is obtained. Such a complete data set provides accurate and reliable basic information for the subsequent layout planning, resource assessment and formulation of mining plans in the mining area, ensuring that all work can be carried out scientifically and effectively under the premise of fully understanding the ore body thickness conditions.

[0038] In one possible implementation, Figure 2 As shown, step S200 also includes:

[0039] Step S210: Using GIS software, create a geological framework of the ore body in the target mining area.

[0040] Step S220: Based on the geostatistical theory, the spatial variability and continuity of the ore body within the ore body geological framework are analyzed to determine the ore body morphological characteristics and ore body distribution characteristics.

[0041] Step S230: Visually express the ore body morphology and distribution characteristics in the ore body geological framework through the ore body prediction map of the target mining area, and determine the ore body geological space in the target mining area.

[0042] Specifically, we first use GIS software to start the creation work. With its powerful spatial data processing and analysis capabilities, GIS software provides a powerful tool for constructing the geological framework of the ore body in the target mining area. By inputting the relevant geographic information and geological data of the area, the software gradually builds an initial framework structure that can accommodate and integrate various information. This framework is like a virtual container, laying the foundation for the subsequent in-depth analysis and processing of the ore body geological information.

[0043] Geostatistics theory has become a key analytical tool. First, from the perspective of spatial variability, within the constructed ore body geological framework, due to the complexity and diversity of geological actions, the various properties of the ore body will show differences in different spatial locations. For example, the grade of the ore may be higher in some areas and lower in others; the thickness of the ore body may vary due to changes in geological structure. Through statistical analysis of a large amount of sampling data and the use of tools such as variograms in geostatistics, the degree of change and the law of change of these properties can be quantitatively described. Next, for the analysis of continuity, the continuity of the ore body in space is crucial for the planning of mining projects and the evaluation of resources. By studying the extension trend, connection relationship, fracture and discontinuity of the ore body in different directions, it can be judged whether the ore body is a continuously distributed large ore body or an ore body group composed of multiple small ore bodies. This not only involves direct observation of the ore body itself, but also requires a comprehensive judgment based on multiple factors such as geological structure and stratigraphic lithology. Based on the in-depth analysis of spatial variability and continuity, the morphological characteristics of the ore body can be determined. The morphology of the ore body can be varied, such as layered, veined, lens-shaped, etc. By analyzing the boundary shape, trend, inclination, dip and other parameters of the ore body, the geometric form of the ore body can be accurately described. At the same time, the determination of the distribution characteristics of the ore body includes the distribution range, density and relationship with the surrounding geological bodies in the entire mining area. These distribution characteristics will directly affect the selection of mining methods, the layout of the development system and the comprehensive utilization of resources. Through such a comprehensive and in-depth analysis, a solid theoretical foundation and accurate geological information are provided for subsequent mining work.

[0044] The ore body prediction map of the target mining area has become a key medium for realizing visual expression. First, based on the ore body prediction map of the mining area, the ore body morphological characteristics and ore body distribution characteristics obtained from the previous analysis are gradually mapped into the ore body geological framework. For the ore body morphological characteristics, for example, if it is a layered ore body, its approximate layered structure will be clearly presented in the framework, including the thickness, extension direction and inclination angle of the layer; if it is a vein ore body, its narrow and long trend and branch veins will be highlighted. For the ore body distribution characteristics, such as the density distribution of the ore body in the entire mining area, it will be distinguished by different color depths, line density or specific symbol identification. In the process of visual expression, advanced graphics processing technology and three-dimensional modeling technology are used to enable these features to be presented in an intuitive and vivid form. For example, through a three-dimensional three-dimensional image, the ore body's morphology and distribution can be observed from different angles. Such visual expression not only helps to clearly understand the geological structure of the ore body, but also enables a more intuitive understanding of the ore body. With the complete presentation of the ore body morphological characteristics and ore body distribution characteristics in the ore body geological framework, the ore body geological space in the target mining area is finally determined. This space is no longer an abstract concept and data collection, but a concrete, visual virtual scene. In this scene, every detail clearly shows the real situation of the ore body, providing a reliable basis for subsequent mining engineering design, resource assessment, safe production planning, etc. Whether it is determining the mining plan, planning the transportation channel, or evaluating the potential geological risks, scientific and accurate decisions can be made based on this visualized ore body geological space, which greatly improves the efficiency and safety of mining work.

[0045] In a possible implementation, step S300 further includes:

[0046] Step S310: When the ore body thickness data is greater than the first preset thickness data, the target layout method adopts the vertical layout method in the first type of combined layout method. Correspondingly, the adjacent layered mine chambers are arranged alternately along the ore body strike and vertical to the ore body strike. At the same time, the lower layered mine chamber vertically passes through multiple artificial false bottoms.

[0047] Specifically, when the ore body thickness data is greater than the first preset thickness data (here set to 20m), a vertical layout method in a combination layout method will be adopted in the mining layout. Under this vertical layout method, the layout of adjacent layered mine chambers presents a unique pattern. On the one hand, they are arranged along the strike of the ore body to ensure that the resources of the ore body in the strike direction can be fully utilized; on the other hand, they are staggered perpendicular to the strike of the ore body. Such a staggered arrangement has many advantages, which can make mining operations more efficient and orderly. For example, mining operations can be carried out simultaneously in mine chambers of different layers without interfering with each other, and the loss and dilution of ore can be minimized. At the same time, the lower layer mine chamber will vertically pass through multiple artificial false bottoms. Artificial false bottoms play an important supporting and protective role in the mining process. The lower layer mine chamber vertically passes through these artificial false bottoms to ensure the stability and safety of the mine chamber. In actual operation, the relationship between the lower layer mine chamber and the artificial false bottom is accurately calculated and designed to ensure that the structural stability of the entire mining system will not be adversely affected during the passing process. This layout and structural design is the result of comprehensive consideration of multiple factors such as ore body thickness, mining efficiency, safety, and resource recovery, and can provide strong guarantees for efficient and safe mining operations.

[0048] In a possible implementation, step S300 further includes:

[0049] Step S320: When the ore body thickness data is greater than the second preset thickness data and less than the first preset thickness data, the target layout method adopts the oblique layout method in the first type of combined layout method. Correspondingly, the adjacent layered mine rooms are staggered along the ore body strike and the oblique ore body strike. At the same time, the lower layered mine room obliquely passes through multiple artificial false bottoms.

[0050] Specifically, when the ore body thickness data is within a specific range, that is, greater than the second preset thickness data (10m) and less than the first preset thickness data, an oblique layout method in a type of combined layout method will be adopted. For this oblique layout method, the layout of adjacent layered mine chambers will take into account the ore body strike and the oblique direction at a certain angle to the ore body strike. The layout along the ore body strike can ensure the effective follow-up and utilization of ore body resources, while the staggered layout of the oblique ore body strike brings more flexibility and adaptability. This layout method makes the spatial relationship between the mine chambers more reasonable, and can reduce the blind spots or inefficiencies in resource mining that may be caused by a single strike layout. In different layered mine chambers, through this staggered layout, mining operations can be distributed more evenly and the overall mining efficiency can be improved. At the same time, the lower layered mine chamber will obliquely pass through multiple artificial false bottoms, which play a vital role in supporting and isolating in the mining process. The lower layered mine chamber passes through them in an oblique manner, which requires precise engineering design and construction control. The oblique crossing method must take into account the stability of the mine room itself and ensure that the structural integrity of the artificial false bottom will not be damaged. In actual operation, it is necessary to reasonably determine the oblique angle and the crossing method based on factors such as the specific ore body thickness, geological conditions, and mining process requirements to achieve the best mining effect and safety. This oblique layout method and the relationship between the lower layer mine room and the artificial false bottom are scientific decisions made after comprehensive consideration of multiple factors, providing a strong guarantee for the smooth progress of mining operations and the efficient recovery of resources.

[0051] In a possible implementation, step S320 further includes:

[0052] Step S321: When the ore body thickness data is less than the second preset thickness data, the target layout method adopts the layout method along the ore body strike in the first type of combined layout method. Correspondingly, the adjacent layered mine rooms are arranged along the ore body strike. At the same time, the number of artificial false bottoms exposed simultaneously on the roof of the lower layered mine room is not less than 2.

[0053] Specifically, when the ore body thickness data is less than the second preset thickness data, the layout method adopted will change accordingly. In this case, the target layout method selects a layout method along the ore body strike in a class of combined layout methods. Because the ore body thickness is relatively thin, it is a more reasonable choice to arrange adjacent layered mine rooms along the ore body strike. Such a layout method can conform to the natural form of the ore body to the greatest extent, so that the mining operation is consistent with the strike of the ore body, which is conducive to reducing the engineering difficulty and cost in the mining process. Under this layout, the mining and transportation of ore can be more efficient and convenient, avoiding additional engineering and resource waste caused by the inconsistency between the layout direction and the strike of the ore body. At the same time, for the lower layered mine room, an important feature is that the number of artificial false bottoms exposed by its roof at the same time is not less than 2. The artificial false bottom plays a key supporting and protective role in the mining process. When the roof exposes at least 2 artificial false bottoms at the same time, it can provide a more stable support structure for the lower layered mine room and enhance the stability and safety of the mine room. This is particularly important for mining operations in thinner ore bodies, and can effectively prevent the collapse of the roof and other safety accidents. In actual operation, it is necessary to accurately design and construct the artificial false bottom according to the specific ore body thickness and geological conditions to ensure that it can meet the support and protection requirements of the lower layer mine room, thereby ensuring the smooth progress of mining operations and the safety of personnel.

[0054] In a possible implementation, step S600 further includes:

[0055] Step S610: using finite element analysis software, evaluating the layout stability of the lower layered mine chamber corresponding to the adjacent layered mine chambers and the artificial false bottom corresponding to the cross-connected tunnels before the geological space fitting of the ore body is reset.

[0056] Step S620: Based on the ore body thickness data, rock mechanical properties are introduced, and the first preset thickness data and the second preset thickness data are adaptively updated through the layout stability.

[0057] Specifically, finite element analysis software has become a key tool for evaluating layout stability. First, in the complex three-dimensional environment of the ore body geological space, the software begins to accurately fit the lower layer mine room and artificial false bottom before the reset. It will integrate a lot of information such as the actual geological structure, mine room size, and material properties of the artificial false bottom into the model. For the lower layer mine room, the software will carefully consider its spatial position, shape, and relationship with the surrounding ore body and other structures. As a key area for mining operations, the stability of the lower layer mine room is directly related to the safety and efficiency of subsequent mining work. Finite element analysis software also attaches great importance to the artificial false bottom corresponding to the cross-connected tunnels. The artificial false bottom plays an important role in supporting the upper structure and maintaining the stability of the tunnel. The software will accurately simulate its stress and deformation under various stress conditions. After completing the fitting work, the software begins to evaluate the stability of the entire layout. It will analyze the stress distribution, deformation degree and possible failure mode of the lower layer mine room and artificial false bottom under different working conditions, such as ground pressure changes, mining vibrations, groundwater influence and other factors. By calculating various mechanical parameters, such as stress, strain, displacement, etc., it determines whether the current layout can withstand the various forces that may be faced during the mining process and whether there are potential unstable factors. For example, when simulating the increase in ground pressure, the software will monitor the stress changes of the lower layer mine room and artificial false bottom to see if they will exceed the bearing limit of their materials; when considering mining vibrations, it will evaluate the impact of such vibrations on structural stability and whether they will cause loosening or damage. Through such a comprehensive and in-depth evaluation, a scientific basis can be provided for subsequent layout optimization and adjustment to ensure that mining operations are carried out in a stable and reliable environment.

[0058] As basic information, ore body thickness data plays an important leading role. First, considering that ore body thickness data reflects the scale and changes of the ore body in the vertical direction, it directly affects the design and stability assessment of the mining layout. On this basis, rock mechanical properties are introduced. Rock mechanical properties cover key parameters such as rock strength, hardness, elastic modulus, Poisson's ratio, etc. These parameters are crucial for understanding and evaluating the mechanical behavior of the rock around the ore body. Because in the mining process, the mechanical properties of the surrounding rocks will have a profound impact on the stability of the mine room and tunnel. The layout stability results obtained by the previous evaluation using finite element analysis software are used as feedback information to guide the update of the first preset thickness data and the second preset thickness data. If the layout stability evaluation shows that the current preset thickness data may cause layout instability in some cases, or cannot fully adapt to the actual mining conditions, adaptive updates are required. For example, when it is found that the ore body thickness has changed with the progress of mining, or the rock mechanical properties indicate that the bearing capacity of the surrounding rocks is different from the previous expectations, the preset thickness data needs to be adjusted according to this new information, and the appropriate thickness range will be recalculated according to the new ore body thickness and rock mechanical properties to ensure that the mining layout can remain stable under different geological conditions and mining stages. During the updating process, the interaction of multiple factors will be comprehensively considered. For example, it is necessary to ensure the stability of the mine room and tunnel, and to take into account the maximization of mining efficiency and resource recovery. By continuously and adaptively updating the first preset thickness data and the second preset thickness data according to the actual situation, the mining layout can always be in the optimal state, adapting to the ever-changing geological and mining conditions, and providing a solid guarantee for efficient and safe mining operations.

[0059] In a possible implementation, step S600 further includes:

[0060] Step S630: after the first single-layer layout position distribution structure overlaps with the second single-layer layout position distribution structure, an augmented link is determined by a network flow algorithm, wherein the network flow algorithm uses forward edges for exploration.

[0061] Step S640: Time series augmented link determination formula:

[0062] ,in, It is used to represent the augmented link in the time series, and Path is used to represent the forward edge. The corresponding multiple paths, It is the forward edge The capacity at time t, It is the forward edge The reverse capacity at time t, It is the forward edge The standard deviation of the flow at time t, λ is the decay factor used to consider the effect of time on the capacity weight.

[0063] Step S650: Based on the augmented link, the M auxiliary lines and the N auxiliary lines are adjusted to reset the lower layered mine room corresponding to the adjacent layered mine room and the artificial false bottom corresponding to the cross-connected tunnel.

[0064] Specifically, after the first single-layer layout position distribution structure overlaps with the second single-layer layout position distribution structure, the network flow algorithm is used to determine the augmenting link. The network flow algorithm plays a vital role in this process. It uses the forward edge to explore and is based on the maximum flow minimum cut theorem. The maximum flow minimum cut theorem is an important theorem in network flow theory, which states that in a network, the value of the maximum flow is equal to the capacity of the minimum cut. In our scenario, this theorem can help us find the optimal augmenting link. The network flow algorithm starts from the source node and gradually explores the entire network along the forward edge. During the exploration process, the algorithm calculates the flow and capacity of each edge and determines which edges can be used as augmenting links based on the maximum flow minimum cut theorem. For example, if the flow of a forward edge has not yet reached its capacity, then this edge may become an augmenting link. The algorithm will continuously adjust the flow distribution of the edge to find an augmenting link that can increase the total flow. By exploring forward edges and based on the maximum flow minimum cut theorem, the network flow algorithm can accurately determine the augmented links in complex layout structures, providing an important basis for subsequent layout optimization.

[0065] When determining the augmented link, the time series augmented link determination formula is used, where: It is used to accurately characterize the augmented links in the time series, and Path is used to characterize the forward edge. The corresponding multiple paths, is the capacity of the forward edge at time t, which reflects the amount of traffic that the forward edge can carry at that time point; is the reverse capacity of the forward edge at time t, reflecting the potential for reverse flow; is the standard deviation of the forward edge at time t, which is used to measure the stability and volatility of the circulation; λ is the attenuation factor, which is used to specifically consider the impact of time on the capacity weight. As time goes by, the capacity weight may change, and the attenuation factor can reasonably adjust this change.

[0066] Based on the previously determined augmented links, the M auxiliary lines and N auxiliary lines are adjusted. This is a critical step that directly affects the reset of the lower layered mine room corresponding to the adjacent layered mine room and the artificial false bottom corresponding to the cross-connected roadway. First, the information of the augmented links is carefully analyzed, including its position, direction and related parameters, which will guide the adjustment direction and amplitude of the auxiliary lines. For example, if the augmented links indicate that a certain area needs to increase the layout density of the mine room or adjust the direction of the roadway, the corresponding auxiliary lines will be moved and adjusted in this direction. For the M auxiliary lines, their positions, lengths or angles will be modified according to the instructions of the augmented links. These adjustments are intended to better adapt to the geological characteristics and mining needs of the ore body to improve mining efficiency and safety. At the same time, the N auxiliary lines will also be similarly adjusted to ensure that the layout of the cross-connected roadways is more reasonable. In the process of adjusting the auxiliary lines, it is necessary to comprehensively consider a variety of factors, such as the thickness, morphology, distribution characteristics of the ore body, and the performance and operation requirements of the mining equipment. Through precise calculation and simulation, it is ensured that the adjustment of the auxiliary lines can optimize the mining layout to the greatest extent. As the auxiliary lines are adjusted, the lower layer chambers corresponding to the adjacent layer chambers and the artificial false bottoms corresponding to the cross-connected tunnels will also be reset. The location, size, and shape of the lower layer chambers will be replanned based on the adjusted auxiliary lines to ensure that the ore can be mined more efficiently and safely. The setting of the artificial false bottom will also be optimized accordingly to provide better support and protection. By adjusting the auxiliary lines based on augmented links and resetting the lower layer chambers and artificial false bottoms, the layout of the mining area can be optimized, the efficiency and safety of mining operations can be improved, and the geological conditions and mining requirements of the ore body can be better adapted.
