[0038] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0039] As land acquisition policies are gradually improved, the high cost of land acquisition, the complicated procedures for forest, grass and soil, and the long time spent on land use have seriously affected the normal production of major open-pit coal mines. Less land acquisition can speed up the progress of land acquisition, reduce land acquisition costs, and ensure the efficient operation of open-pit coal mines; the transportation cost of open-pit coal mines accounts for about 50% of the production cost, and the transportation cost is mainly reflected in the length of the transportation distance. Short transportation distance is an important topic in theoretical research and production practice of open-pit coal mines; slope landslide is one of the major safety hazards of open-pit coal mines, and it is also a hot topic studied by open-pit scholars. Stabilizing slopes is the eternal goal pursued by government departments and enterprises at all levels.

[0040] In traditional mining activities, the planning of spoil dumps is often done manually, ignoring the integration with land acquisition information, resulting in problems such as long spoil transportation distances and low efficiency.

[0041] In view of the problems of the above-mentioned related technologies, the method for planning the spoil dump of open-pit coal mines in the Loess Plateau region disclosed in this invention reduces the number of villages and communities involved in land acquisition by using mining theory and land acquisition information, and reduces the difficulty and cost of land acquisition; by optimizing the layout of the spoil dump, the distance of spoil transportation is reduced, thereby reducing transportation costs. At the same time, the timely connection and mutual support strategy of the internal and external spoil dumps improves mining efficiency and shortens the mining cycle; the time-effect slope theory is used to ensure the stability of the slope and reduce the risk of safety accidents.

[0042] The following describes in detail with reference to the accompanying drawings a method, device, electronic equipment and medium for planning an open-pit coal mine dump in the Loess Plateau region proposed in the present disclosure.

[0043] Figure 1 The following is a flow chart of a method for planning an open-pit coal mine dump in the Loess Plateau region provided by an embodiment of the present disclosure. Figure 1 As shown, the method comprises the following steps:

[0044] Step 101: Determine an initial dumping ground, which includes an inner dumping ground and an outer dumping ground.

[0045] In the embodiments of the present disclosure, the layout of the initial spoil dump is determined after comprehensive consideration of factors such as the mining plan, geological conditions, topography, and environmental protection requirements of open-pit coal mines in the Loess Plateau. The initial spoil dump consists of an inner spoil dump and an outer spoil dump. The inner spoil dump is usually located near the mining site and is used to store waste rock and strippings generated during the mining process; the outer spoil dump is located at a relatively distant location and is used to accommodate excess waste rock and strippings. The present disclosure can maximize the use of space, reduce transportation costs, and ensure the stability and safety of the slope by using mining theory and land acquisition information for reasonable layout.

[0046] Step 102: Connect the inner dump and the outer dump to obtain a first dump.

[0047] In the embodiments of the present disclosure, in order to optimize the overall layout of the spoil dump and improve the transportation efficiency, the present disclosure will connect the inner spoil dump and the outer spoil dump. The connection treatment includes but is not limited to the construction of transportation roads, the installation of drainage facilities, etc., to ensure that waste rock and stripping materials can be smoothly transported from the mining site to the spoil dump. Through the connection treatment, the present disclosure can obtain a more compact and efficient spoil dump layout, namely the first spoil dump.

[0048] Step 103: Based on the spatiotemporal relationship between the inner dump and the outer dump in the first dump, combined with the time-effect slope theory, the first dump is subjected to coordinated slope compression treatment to obtain a second dump, so as to utilize the second dump for open-pit coal mine transportation in the Loess Plateau.

[0049] In an embodiment of the present disclosure, the present disclosure performs collaborative compaction treatment on the first dump yard based on the spatiotemporal relationship between the inner dump yard and the outer dump yard in the first dump yard, combined with the time-effective slope theory. Collaborative compaction treatment is an optimization method that adjusts the slope parameters of the dump yard, such as the slope angle, shape, and height, so that the inner and outer dump yards support each other and deform collaboratively in time and space. The present disclosure discloses that collaborative compaction treatment can not only improve the stability of the dump yard and reduce the risk of slope landslides, but also optimize transportation routes and reduce transportation distances and costs. Through collaborative compaction treatment, the present disclosure can obtain a more stable and efficient second dump yard, which provides strong support for the transportation of open-pit coal mines in the Loess Plateau.

[0050] In summary, the method for planning open-pit coal mine dumps in the Loess Plateau region provided by the embodiments of the present disclosure determines an initial dump, which includes an inner dump and an outer dump; the inner dump and the outer dump are connected to obtain a first dump; based on the spatiotemporal relationship between the inner dump and the outer dump in the first dump, combined with the time-effective slope theory, the first dump is collaboratively compacted to obtain a second dump, so as to utilize the second dump for open-pit coal mine transportation in the Loess Plateau region, thereby effectively improving the transportation efficiency and safety of open-pit coal mines in the Loess Plateau region.

[0051] Figure 2 A schematic flow chart of a method for planning an open-pit coal mine dump in the Loess Plateau region provided in an embodiment of the present disclosure. Figure 2 based on Figure 1 In the embodiment shown, step 101, step 102 and step 103 are further defined. Figure 2 In the embodiment shown, step 101 includes step 201 and step 202, step 102 includes step 203, step 204 and step 205, step 102 includes step 206, and step 103 includes step 207 and step 208. Figure 2 As shown, the method includes the following steps.

[0052] Step 201: Analyze mining theory and land acquisition information to determine the initial spoil dump.

[0053] In the embodiments of the present disclosure, in order to provide a scientific basis for the subsequent planning and design of the spoil dump and ensure that the setting of the spoil dump not only meets the needs of mining operations but also complies with environmental protection and safety requirements, the present disclosure requires an in-depth analysis of mining theory, including understanding the amount, nature, transportation method and environmental impact of waste rock and stripping materials in the mining process. At the same time, combined with land acquisition information, including local land acquisition policies, land nature, ownership of use rights, topography, hydrogeological conditions, traffic conditions and environmental protection requirements, the location, area, shape and capacity of the initial spoil dump are determined after comprehensive consideration.

[0054] Step 202: Determine the inner dump and the outer dump in the initial dump according to the division rule corresponding to the initial dump.

[0055] In the embodiments of the present disclosure, after the initial spoil dump is determined, in order to optimize the layout of the spoil dump, improve transportation efficiency, reduce transportation costs, and ensure environmental protection and safety requirements, the present disclosure needs to divide the initial spoil dump into an inner spoil dump and an outer spoil dump according to division rules (such as the distance from the mining site, terrain conditions, transportation costs, environmental protection requirements, etc.). The inner spoil dump is usually located near the mining site to facilitate the timely discharge and transportation of waste rock and stripping materials; the outer spoil dump is located at a relatively far location to accommodate excess waste rock and stripping materials, while considering its impact on the surrounding environment.

[0056] Step 203: Determine the mining and drainage operation status and the final form of the initial dumping ground.

[0057] In the embodiments of the present disclosure, the state of a procurement operation refers to the four stages of entry, backup, operation and completion and their corresponding states experienced from the time the operation enters the system to the end of the operation.

[0058] The final form of the initial spoil dump refers to the state of a giant artificial loose cushion body formed after the concentrated discharge of mining waste. Specifically, it may include the height, area, shape and capacity of the initial spoil dump after mining and drainage operations.

[0059] As mining operations proceed, the disclosure needs to track and monitor the status of mining and drainage operations in real time, including the amount of waste rock and stripping material generated, transportation efficiency, discharge location, and the capacity of the spoil dump. At the same time, according to the mining progress and planning, the final form of the initial spoil dump is predicted and determined. The purpose of this step is to timely adjust and optimize the layout and capacity of the spoil dump to meet the needs of mining operations and ensure the stability and safety of the spoil dump.

[0060] Step 204: Based on the mining and drainage operation status, the final form, and the preset safety distance, the layout information of the inner dump and the outer dump is adjusted to obtain the adjusted inner dump and the outer dump.

[0061] In an embodiment of the present disclosure, during the mining process, due to changes in geological conditions, adjustments to the mining schedule, and increased safety requirements, the present disclosure requires adjustments to the layout of the inner and outer dumps. The purpose of this step is to optimize and adjust the layout of the inner and outer dumps according to the mining and drainage operation status, final form, and preset safety distances (such as slope stability requirements, transportation road width, environmental protection requirements, etc.) to improve transportation efficiency, reduce transportation costs, ensure slope stability, and meet environmental protection and safety requirements. Among them, adjusting the layout information of the inner and outer dumps can specifically be connecting the inner and outer dumps, and overlapping the outer dump with the mining boundary.

[0062] It is understandable that the preset safety distance disclosed in the present invention can be pre-set or calculated based on the actual situation of the current initial spoil dump.

[0063] Among them, the preset safety distance is calculated according to the actual situation of the current initial dumping ground, including:

[0064] The linear regression model is used to determine the preset safety distance between the external dump and the internal dump, which can be achieved through the following formula:

[0065] A=zk(x+y)

[0066] Among them, A represents the safety distance, z represents the equipment load, x represents the step height, y represents the bucket capacity of the mining equipment, and k represents the constant coefficient, and their values ​​are all scalars.

[0067] Step 205: Based on the adjusted inner dump and outer dump, monitor the formation of the goaf.

[0068] In the embodiments of the present disclosure, goaf refers to a hollow area below the surface created by human excavation (such as mining) or natural geological movement. During the mining process, goafs are formed as ore is mined. The present disclosure can use the adjusted inner and outer dumps as monitoring points to monitor the formation of goafs in real time, including the location, size, shape, and stability of the goafs. By monitoring and analyzing the formation of goafs, potential safety hazards can be discovered and dealt with in a timely manner to ensure the safety of mining operations.

[0069] Step 206: When the formation of the goaf reaches the preset processing conditions, the adjusted inner dump and outer dump are connected to obtain a first dump.

[0070] In an embodiment of the present disclosure, when the formation of the goaf reaches the preset processing conditions (such as the stability of the goaf, the accumulation of waste rock and stripping materials to a certain amount, etc.), the adjusted inner and outer dumps need to be connected for processing. Among them, the preset processing conditions can be set according to the actual situation and are not limited in the present disclosure. The present disclosure can specifically connect the adjusted inner and outer dumps by measures such as building transportation roads and setting drainage facilities to form a more compact and efficient dump layout, i.e., the first dump. At the same time, the present disclosure needs to ensure safety and environmental protection requirements during the connected processing.

[0071] Step 207: Using the time-dependent slope theory, determine the height of the inner dump.

[0072] In the embodiments of the present disclosure, the time-dependent slope theory is a theory that studies the deformation and failure laws of slopes over time. The present disclosure can use the time-dependent slope theory and combine the actual conditions of the inner dump (such as geological conditions, climatic conditions, transportation requirements, etc.) to determine the reasonable height increase of the inner dump. By reasonably determining the height increase, the stability of the slope can be ensured, the risk of safety accidents such as landslides can be reduced, and the needs of mining operations can be met.

[0073] Step 208: Based on the spatiotemporal relationship between the inner dump and the outer dump in the first dump, determine a coordinated compaction plan for the inner dump and the outer dump, and based on the coordinated compaction plan, perform coordinated compaction processing on the first dump to obtain a second dump.

[0074] In the embodiments of the present disclosure, in the planning and design of the spoil dump, the time-space relationship refers to the mutual connection and influence between the inner spoil dump and the outer spoil dump in time and space. Specifically, this includes their positional relationship (such as relative distance, orientation, etc.), the degree of matching of shape and size, the discharge and transportation sequence of waste rock and stripping materials, and the temporal sequence, etc. These time-space relationships have an important impact on the overall stability and carrying capacity of the spoil dump, the discharge and transportation efficiency of waste rock and stripping materials, and the safety and environmental protection requirements of mining operations.

[0075] Collaborative shoring is an optimization method that adjusts the slope angle, shape, height and other parameters of the dump so that the inner and outer dumps can support each other and deform in coordination in time and space. This method aims to improve the overall stability and carrying capacity of the dump while optimizing the discharge and transportation efficiency of waste rock and strippings. The collaborative shoring scheme needs to consider factors such as the relative position, shape, height and slope stability of the inner and outer dumps, and ensure that the dump remains stable and safe during mining operations through precise calculation and design.

[0076] The present disclosure can determine a reasonable collaborative compaction scheme based on the spatiotemporal relationship between the inner dump and the outer dump in the first dump. The collaborative compaction scheme needs to consider the spatiotemporal relationship between the inner dump and the outer dump (e.g., factors such as relative position, shape, height, and slope stability). Then, according to the collaborative compaction scheme, the first dump is subjected to collaborative compaction treatment to improve the overall stability and transportation efficiency of the dump, and to obtain an optimized second dump. During the treatment process, it is necessary to ensure safety and environmental protection requirements, and to monitor and handle possible safety hazards in real time.

[0077] The collaborative pressure relief scheme disclosed in the present invention can specifically be to accurately calculate the capacity, shape and height of the inner and outer dumps, design reasonable slope angles and forms, so that the inner and outer dumps can support each other in time and space and deform in coordination, so as to improve the overall stability and carrying capacity of the dump, while optimizing the discharge and transportation efficiency of waste rock and stripping materials, and ensure the safety and environmental protection requirements of mining operations. The collaborative pressure relief scheme disclosed in the present invention can specifically include measures such as reinforcing slopes and optimizing drainage systems.

[0078] In addition, based on the spatial-temporal relationship between the inner and outer dumps in the first dump, the present disclosure combines the time-effective slope theory to perform collaborative compaction treatment on the first dump to obtain a second dump. Afterwards, the present disclosure also includes: based on the second dump, formulating a dump planning map, and displaying the dump planning map, wherein the dump planning map includes the second dump.

[0079] Specifically, the present disclosure can formulate a detailed spoil dump planning map based on the shape and parameters of the second spoil dump. The spoil dump planning map should include information such as the shape, size, location of the second spoil dump, and the route and method of waste rock discharge. After obtaining the spoil dump planning map, the spoil dump planning map can be displayed so that relevant personnel can understand the layout and parameters of the second spoil dump. Among them, the display method can be an electronic screen display, a paper drawing display, or an online platform display, etc., which is not limited in the embodiments of the present disclosure.

[0080] It is understandable that, as mining operations proceed and the dump morphology changes, the present disclosure can also timely adjust the second dump, and update and optimize the dump planning map based on the timely adjusted second dump. The update content should include information such as new waste rock discharge routes and methods and slope stability monitoring results.

[0081] In summary, the present invention improves transportation efficiency, reduces transportation costs, and ensures the stability and safety of the spoil dump by continuously optimizing the layout and capacity of the spoil dump.

[0082] like Figure 3 As shown, the present disclosure provides a specific schematic diagram of a spoil dump based on an open-pit coal mine spoil dump planning method in the Loess Plateau region.

[0083] In the embodiments of the present disclosure, Figure 3 The effect of the spoil dump after the replanning of the present disclosure can be expressed by the following formula:

[0084]

[0085] Among them: N Village and N Original Village represent the number of villages and communities occupied by the external dump site after re-planning and the original design plan respectively;

[0086] S row and S original row respectively represent the areas occupied by the re-planned and the original designed external spoil banks;

[0087] S village and S original village respectively represent the sum of the areas of the villages and communities occupied by the re-planned and the original designed external spoil banks;

[0088] V inner, V west, and V east respectively represent the volumes of the inner spoil bank, the southwestern and the eastern second external spoil banks after the re-planning of the external spoil bank;

[0089] V original inner, V original west, and V original east respectively represent the volumes of the inner spoil bank, the southwestern and the eastern second external spoil banks in the original design plan of the external spoil bank;

[0090] H inner and H original inner respectively represent the final elevations of the inner spoil bank after re-planning and in the original design plan;

[0091] L to inner represents the distance from the waste to the inner spoil bank after re-planning;

[0092] L to outer and L to original outer respectively represent the distances from the waste to the external spoil bank after re-planning and in the original design plan;

[0093] F before pressing represents the slope stability coefficient of the inner spoil bank before the inner and outer spoil banks press against each other;

[0094] F final represents the slope stability coefficient of the connected slope of the inner and outer spoil banks after the inner and outer spoil banks press against each other.

[0095] Refer to Figure 3 , in the spoil bank planned for the opencast coal mine in the Loess Plateau region disclosed in this disclosure, N village = 4, N original village = 7, and the land acquisition work for three villages and communities is reduced in total for the southwestern and the eastern second external spoil banks, saving a large amount of land acquisition costs.

[0096] The land utilization rate of the external spoil bank is improved, and the area of ineffective land acquisition is reduced.

[0097] V inner = 578 million cubic meters, V west = 101.57 million cubic meters, V east = 130.15 million cubic meters, V original inner = 398.44 million cubic meters, V original west = 200.2 million cubic meters, V original east = 203.78 million cubic meters. The overall height of the inner spoil bank is increased by 32 meters, the capacity of the inner spoil bank in the first mining area is increased by 110 million cubic meters, and the spoil capacity is increased by 70 million cubic meters due to the pressing against each other between the first mining area and the southwestern and the eastern second external spoil banks. The total capacity of the re-planned spoil bank meets the requirements and conforms to the spatio-temporal deduction relationship.

[0098] H inner = 1208 meters, H original inner = 1176 meters, and the height of the inner spoil bank is increased by 32 meters.

[0099] L to inside < L to outside, the capacity of the external dumping ground is reduced, and the capacity of the internal dumping ground is increased. The waste originally discharged to the external dumping ground is discharged to the internal dumping ground. Taking 2022 as an example, the transportation distance is saved by 771 meters.

[0100] L to outside <L to original outside. After the inner and outer dumping yards are connected, the transportation distance to the planned outer dumping yard is reduced by 100-200 meters.

[0101] F before pressure>1.0. Before the inner and outer dumps press against each other, the exposure time of the slope of the inner dump is short, about one year. Referring to the "Design Code for Open-Pit Mines in Coal Industry", the temporary slope stability coefficient can be greater than 1.

[0102] Ffinal>1.2, the inner and outer spoil dumps press against each other to form the final slope, and the exposure time is greater than 20 years. Referring to the "Design Code for Open-pit Mines in Coal Industry", the slope stability coefficient must be greater than 1.2.

[0103] In order to implement the method for planning a dump site for open-pit coal mines in the Loess Plateau region provided by the embodiment of the present disclosure, the embodiment of the present disclosure also provides a device for planning a dump site for open-pit coal mines in the Loess Plateau region, such as Figure 4 As shown, the planning device 400 for the open-pit coal mine dump in the Loess Plateau region includes:

[0104] A determination unit 410 is used to determine an initial dumping ground, which includes an inner dumping ground and an outer dumping ground;

[0105] The first processing unit 420 is used to perform continuous processing on the inner dump and the outer dump to obtain a first dump;

[0106] The second processing unit 430 is used to perform coordinated compaction processing on the first dump based on the temporal and spatial relationship between the inner dump and the outer dump in the first dump in combination with the time-effective slope theory to obtain a second dump, so as to utilize the second dump for open-pit coal mine transportation in the Loess Plateau.

[0107] In some embodiments, the determination unit 410 is used to: analyze mining theory and land acquisition information to determine an initial spoil dump; and determine an inner spoil dump and an outer spoil dump in the initial spoil dump according to a division rule corresponding to the initial spoil dump.
