Description

Technical Field

[0001] The present invention relates to the technical field of mining, and more particularly, to a method and system for planning a mining vein excavation path based on GIS under complex geological conditions. Background Art

[0002] With the increasing demand for mineral resources, especially in the field of undersea mineral deposits mining, traditional mining methods are facing more and more challenges. The complex geological conditions, environmental factors and limitations of mining technology in undersea veins often lead to the instability and inefficiency of excavation operations. The exploration and mining of undersea veins not only need to consider geological factors such as the depth and distribution of ore bodies, but also comprehensively evaluate external influencing factors such as ocean currents and wind speeds in the marine environment, as well as the potential impact of mining operations on the ecological environment. Therefore, how to plan the optimal excavation path in the complex undersea environment, improve mining efficiency, and ensure the safety and environmental protection of operations has become a key issue in current marine mining technology.

[0003] Traditional methods for planning mining vein excavation paths mainly rely on static geological exploration data, often failing to fully consider multi-dimensional factors such as the buried position of the vein and changes in the marine environment, resulting in inaccurate path planning, which in turn affects the efficiency and reliability of excavation operations. At the same time, the influence of environmental factors such as ocean currents and wind speeds at sea is often ignored during operations. These factors have an important impact on the safety and drilling speed of mining vein excavation in actual operations, and may cause operation delays, equipment damage, and even irreversible damage to the environment.

[0004] Therefore, it is necessary to provide a method and system for planning a mining vein excavation path based on GIS under complex geological conditions to solve the problems of inaccurate planning and low efficiency of traditional mining path planning methods, which affect safety and operation speed. Summary of the Invention

[0033] If there is a comprehensive index in the historical data that is the same as that of the final mining point, then determine the final value of the drilling speed of this historical data as the initial value of the drilling speed;

[0034] Otherwise, set a standard value of the comprehensive index, and calculate the index difference between the comprehensive index of the final mining point and the standard value of the comprehensive index;

[0035] Pre - set a first difference and a second difference, where the first difference is less than the second difference;

[0037] If the index difference is greater than or equal to the first difference and less than or equal to the second difference, then take the second initial value of the speed as the initial value of the drilling speed;

[0038] If the index difference is greater than the second difference, then take the third initial value of the speed as the initial value of the drilling speed;

[0039] Among them, the first initial value of the speed < the second initial value of the speed < the third initial value of the speed.

[0040] Further, when judging whether to correct the initial value of the drilling speed according to the environmental impact index, it includes:

[0042] If the environmental impact index is less than or equal to the historical environmental impact indices of all historical vein mining points, it is determined that there is no need to correct the initial value of the drilling speed.

[0043] Further, when it is determined that correction is needed and the initial value of the drilling speed is corrected according to the environmental impact index to obtain the final value of the drilling speed, it includes:

[0048] If the impact difference is greater than the second impact difference, adjust the drilling speed by the third correction coefficient;

[0049] Wherein, the value range of the correction coefficient is 1 > the first correction coefficient > the second correction coefficient > the third correction coefficient > 0, and the final value of the drilling speed is the product value of the initial value of the drilling speed and the correction coefficient.

[0050] Compared with the prior art, the beneficial effects of the present invention are as follows: First, by obtaining regional geological data and constructing a three-dimensional spatial distribution map, the present invention can accurately determine the mining area and comprehensively consider key factors such as submarine veins, ocean faults, depth distribution, and rock layers. This process marks and calculates the mining reliability index through GIS tools to initially determine the vein mining points, effectively avoiding human misjudgment and incorrect planning. Second, by combining real-time collected environmental information (such as sea current speed and sea wind speed), calculate the environmental impact index, further optimize the selection of vein mining points, and ensure the safety and efficiency of mining operations. In addition, by comparing the comprehensive index of the vein mining points with historical data, the initial value of the drilling speed can be dynamically adjusted and corrected according to the environmental impact index. This not only improves the accuracy of the operation but also minimizes environmental risks and resource waste. In summary, this method ensures the scientificity, sustainability, and efficiency of vein mining operations by integrating geological, environmental, and operation parameters, thereby significantly improving the mining efficiency of mineral resources and the level of ecological environment protection.

Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0061] In some embodiments of the present application, referring to Figure 1 as shown, this embodiment provides a vein mining path planning method based on GIS under complex geological conditions, including the following steps:

[0062] S100. Obtain the geological data of the area, input the geological data into the GIS system, construct a three-dimensional spatial distribution map of the area, and determine the mining area according to the three-dimensional spatial distribution map; wherein, the mining area is the upper area of the area where the submarine vein is located, and the geological data includes the distribution of submarine veins, the distribution of marine faults, the distribution of ocean depths, and the thickness of rock layers;

[0063] S200. Mark the geological features of the mining area through GIS tools, calculate the mining reliability index according to the geological features, and preliminarily determine the vein mining points according to the mining reliability index; wherein, the geological features include the thickness of the fault, the thickness of the ocean layer, the thickness of the rock layer, and the hardness of the rock layer;

[0064] S300. Collect the environmental information, calculate the environmental impact index according to the environmental information, determine whether it is necessary to adjust the vein mining points according to the environmental impact index, if it is determined that it is necessary to adjust the vein mining points, calculate the comprehensive index according to the mining reliability index and the environmental impact index, and re-determine the vein mining points according to the comprehensive index; wherein, the environmental information includes the sea current speed and the sea wind speed;

[0065] S400. Compare the comprehensive index of the re-determined vein mining points with the comprehensive index of the historical vein mining points, determine the initial value of the drilling speed according to the comparison result, determine whether to correct the initial value of the drilling speed according to the environmental impact index, and if the judgment result is that correction is required, correct the initial value of the drilling speed according to the environmental impact index to obtain the final value of the drilling speed.

[0066] It can be understood that, first of all, by obtaining regional geological data and constructing a three-dimensional spatial distribution map, the present invention can accurately determine the mining area and comprehensively consider key factors such as submarine veins, ocean faults, depth distribution, and rock layers. This process marks and calculates the mining reliability index through GIS tools, preliminarily determines the vein excavation points, and effectively avoids human misjudgment and incorrect planning. Secondly, by combining the real-time collected environmental information (such as sea current speed and sea wind speed), calculates the environmental impact index, and further optimizes the selection of vein excavation points to ensure the safety and efficiency of mining operations. In addition, by comparing the comprehensive index of the vein excavation points with historical data, the initial value of the drilling speed can be dynamically adjusted and corrected according to the environmental impact index. This not only improves the accuracy of the operation but also minimizes environmental risks and resource waste. In summary, this method ensures the scientificity, sustainability, and efficiency of vein excavation operations by integrating geological, environmental, and operation parameters, thereby significantly improving the mining efficiency of mineral resources and the level of ecological environment protection.

[0067] In some embodiments of the present application, when marking the geological characteristics of the mining area through GIS tools, calculating the mining reliability index according to the geological characteristics, and preliminarily determining the vein excavation points according to the mining reliability index, it includes:

[0068] Divide the mining area into several grid areas and number each grid area; where the areas of the grid areas are the same;

[0069] Take the center point of each grid area as the preliminary vein excavation point, and take the vertical path from the preliminary vein excavation point to the vein as the preliminary excavation path;

[0070] Calculate the average hardness of the rock layer of the preliminary excavation path, set the maximum value of the mining reliability index and the maximum value of the geological layer thickness, and calculate the mining reliability index of each preliminary vein excavation point according to the geological characteristics of the preliminary excavation path through the following formula:

[0071] Ri = Rmax * (1 - α1 * hf / hmax - α2 * hr / hmax - α3 * ho / hmax) * (1 - β / kr);

[0072] In the above formula, Ri represents the mining reliability index, Rmax represents the maximum value of the mining reliability index, hf represents the fault thickness value, hmax represents the maximum value of the geological layer thickness, hr represents the rock layer thickness, ho represents the ocean layer thickness, kr represents the average hardness of the rock layer, α1, α2, and α3 respectively represent the influence values of the fault thickness, the rock layer thickness, and the ocean layer thickness, and β represents the influence value of the rock layer hardness; where the value ranges of α1, α2, α3, and β are all 0 - 1;

[0073] Set the standard value of the mining reliability index, and preliminarily determine the pre-mining points corresponding to the mining reliability index greater than or equal to the standard value of the reliability index as the vein mining points.

[0074] It can be understood that the present invention effectively realizes the precise preliminary determination of vein mining points by dividing the mining area into several grids and calculating the mining reliability index according to the geological characteristics of each grid. By considering multiple geological factors such as fault thickness, rock layer thickness, ocean layer thickness, and rock layer hardness, the reliability index of each pre-mining point of the vein is comprehensively calculated, and reliable mining points are screened out by setting a standard value, thereby improving the scientificity and safety of the mining path. This method can not only optimize vein positioning under complex geological conditions, reduce risks and resource waste, but also dynamically adjust the mining strategy to ensure the efficient exploitation and long-term stability of mineral resources.

[0075] In some embodiments of the present application, when collecting environmental information and calculating the environmental impact index according to the environmental information, it includes:

[0076] Pre-set the maximum safe value of the sea current speed and the maximum safe value of the sea wind speed, and calculate the environmental impact index through the following formula:

[0077] Rh = |(Vl - Vlmax) / Vlmax| + |(Vf - Vfmax) / Vfmax|;

[0078] In the above formula, Rh represents the environmental impact index, Vl represents the current sea current speed, Vlmax represents the maximum safe value of the sea current speed, Vf represents the sea wind speed, and Vfmax represents the maximum safe value of the sea wind speed.

[0079] In some embodiments of the present application, when judging whether it is necessary to adjust the vein mining points according to the environmental impact index, it includes:

[0080] Set the maximum value of the environmental impact index. If the environmental impact index is greater than or equal to the maximum value of the environmental impact index, it is judged that there is no need to adjust the preliminarily determined vein mining points;

[0081] If the environmental impact index is less than the maximum value of the environmental impact index, it is judged that it is necessary to adjust the preliminarily determined vein mining points.

[0082] It can be understood that the present invention effectively evaluates the impact of environmental factors on the ore vein mining points by calculating the environmental impact index of the ocean current velocity and the wind speed at sea. By setting the safety maximum values of the ocean current velocity and the wind speed, and calculating the environmental impact index based on the current environmental parameters, potential environmental risks can be identified in a timely manner. If the environmental impact index is lower than the set maximum value, it is automatically determined that the mining point needs to be adjusted to avoid safety hazards or operation delays caused by adverse environmental conditions, thereby optimizing the safety and efficiency of the mining operation. This method not only improves the scientific nature of the mining decision-making, but also enhances the ability to respond to environmental changes, helps reduce environmental damage, and ensures the sustainable exploitation of mineral resources.

[0083] In some embodiments of the present application, when calculating the comprehensive index according to the mining reliability index and the environmental impact index if it is determined that the ore vein mining point needs to be adjusted, it includes:

[0084] The comprehensive index is calculated according to the mining reliability index and the environmental impact index by the following formula:

[0085] Z = a * Ri - b * Rh;

[0086] In the above formula, Z represents the comprehensive index, Ri represents the mining reliability index, Rh represents the environmental impact index, a represents the weight coefficient of the mining reliability index, b represents the weight coefficient of the environmental impact index, where the value ranges of a and b are both 0 - 1.

[0087] It can be understood that the present invention realizes a comprehensive evaluation of the ore vein mining points by calculating the comprehensive index based on the comprehensive mining reliability index and the environmental impact index. By setting the weight coefficients, the influence of the mining reliability and the environmental impact is balanced, making the final decision more scientific and reasonable. If the environmental impact is large and exceeds the expectation, the adjustment of the comprehensive index can timely reflect this change, and then guide the adjustment of the mining point. This method can effectively integrate the geological conditions and environmental factors, optimize the mining decision-making, improve the safety and efficiency of the mining operation, reduce environmental risks, and ensure the efficient and sustainable exploitation of mineral resources.

[0088] In some embodiments of the present application, when re-determining the ore vein mining point according to the comprehensive index, it includes:

[0089] Arrange the comprehensive indexes of the ore vein mining points in descending order;

[0090] The ore vein mining point corresponding to the maximum value of the comprehensive index is re-determined as the ore vein mining point, and the re-determined ore vein mining point is used as the final mining point.

[0091] It is understandable that by arranging the comprehensive index in descending order, it is ensured that the finally selected vein mining point is optimal. By selecting the mining point corresponding to the maximum value of the comprehensive index, the mining reliability and environmental impact can be comprehensively considered to ensure that the mining operation is carried out under the safest and most efficient conditions. This process effectively reduces the uncertainty in the selection of mining points, avoids possible risks and resource waste, thereby enhancing the overall efficiency and safety of vein mining and ensuring the scientific nature and sustainability of the operation.

[0092] In some embodiments of the present application, when comparing the comprehensive index of the re-determined vein mining point with the comprehensive index of the historical vein mining point and determining the initial value of the drilling speed according to the comparison result, it includes:

[0093] If there is a comprehensive index in the historical data that is the same as the final mining point, then determine the final value of the drilling speed of this historical data as the initial value of the drilling speed;

[0094] Otherwise, set a standard value of the comprehensive index, and calculate the index difference between the comprehensive index of the final mining point and the standard value of the comprehensive index;

[0095] Preset a first difference and a second difference, where the first difference is less than the second difference;

[0096] If the index difference is less than the first difference, then use the first initial value of the drilling speed as the initial value of the drilling speed;

[0097] If the index difference is greater than or equal to the first difference and less than or equal to the second difference, then use the second initial value of the drilling speed as the initial value of the drilling speed;

[0098] If the index difference is greater than the second difference, then use the third initial value of the drilling speed as the initial value of the drilling speed;

[0099] Wherein, the first initial value of the drilling speed < the second initial value of the drilling speed < the third initial value of the drilling speed.

[0100] It is understandable that by comparing the comprehensive index of the final mining point with the historical data and adjusting the initial value of the drilling speed according to the index difference, the drilling speed can be accurately determined according to the actual situation of the vein mining point. This method takes into account the similarity between the historical data and the new mining point, effectively avoiding the problem of inaccurate drilling speed caused by the lack of reference data. By setting different ranges of the initial value of the speed, the adaptability of the operation under different conditions is ensured, the adjustment process of the drilling speed is optimized, and the efficiency and safety of the mining operation are improved. In addition, this precise speed adjustment helps to reduce equipment wear, reduce risks, and improve the mining efficiency of mineral resources.

[0101] In some embodiments of the present application, when judging whether to correct the initial value of the drilling speed according to the environmental impact index, it includes:

[0102] If the environmental impact index exceeds the historical environmental impact indices of all historical vein mining points, it is determined that the initial drilling speed needs to be corrected;

[0103] If the environmental impact index is less than or equal to the historical environmental impact indices of all historical vein mining points, it is determined that the initial drilling speed does not need to be corrected.

[0104] In some embodiments of the present application, when the determination result is that correction is required and the initial drilling speed is corrected according to the environmental impact index to obtain the final drilling speed, it includes:

[0105] Calculate the impact difference between the environmental impact index and the maximum value of the historical environmental impact indices, and adjust the initial drilling speed according to the impact difference;

[0106] Set a first impact difference and a second impact difference; wherein, the first impact difference is less than the second impact difference;

[0107] If the impact difference is less than the first impact difference, adjust the initial drilling speed through the first correction coefficient;

[0108] If the impact difference is greater than or equal to the first impact difference and less than or equal to the second impact difference, adjust the drilling speed through the second correction coefficient;

[0109] If the impact difference is greater than the second impact difference, adjust the drilling speed through the third correction coefficient;

[0110] Wherein, the value range of the correction coefficient is 1 > the first correction coefficient > the second correction coefficient > the third correction coefficient > 0, and the final drilling speed is the product value of the initial drilling speed and the correction coefficient.

[0111] It can be understood that by comparing the environmental impact index with historical data, the initial drilling speed is flexibly adjusted to ensure the adaptability and safety of operations under different environmental conditions. If the environmental impact index exceeds the maximum value in the historical data, the system will automatically judge and correct the drilling speed to adapt to more complex environmental factors. By setting the impact difference and the correction coefficient, the method can make fine adjustments according to specific environmental changes, thereby effectively optimizing the drilling speed and avoiding resource waste or equipment damage caused by too fast or too slow drilling. This dynamic adjustment mechanism improves the safety, efficiency and controllability of vein mining, and helps to ensure the stability and long-term sustainability of the operation process.

[0112] On the other hand, referring to Figure 2 as shown, the present application also provides a GIS-based vein mining path planning system under complex geological conditions for applying the above-mentioned GIS-based vein mining path planning method under complex geological conditions, including:

[0113] The distribution map drawing module is configured to obtain the geological data of the area, input the geological data into the GIS system, construct a three-dimensional spatial distribution map of the area, and determine the mining area according to the three-dimensional spatial distribution map; wherein, the mining area is the area above the area where the submarine vein is located, and the geological data includes the distribution of submarine veins, the distribution of ocean faults, the distribution of ocean depths, and the rock thickness.

[0114] The preliminary determination module of the mining point is configured to mark the geological features of the mining area through GIS tools, calculate the mining reliability index according to the geological features, and preliminarily determine the vein mining points according to the mining reliability index; wherein, the geological features include the fault thickness, the ocean layer thickness, the rock layer thickness, and the rock layer hardness.

[0115] The re-determination module of the mining point is configured to collect environmental information, calculate the environmental impact index according to the environmental information, judge whether it is necessary to adjust the vein mining points according to the environmental impact index, and if it is judged that it is necessary to adjust the vein mining points, calculate the comprehensive index according to the mining reliability index and the environmental impact index, and re-determine the vein mining points according to the comprehensive index; wherein, the environmental information includes the sea current speed and the sea wind speed.

[0116] The drilling speed determination module is configured to compare the comprehensive index of the re-determined vein mining point with the comprehensive index of the historical vein mining point, determine the initial value of the drilling speed according to the comparison result, judge whether to correct the initial value of the drilling speed according to the environmental impact index, and if the judgment result is that correction is required, correct the initial value of the drilling speed according to the environmental impact index to obtain the final value of the drilling speed.

[0117] It can be understood that the vein mining path planning system realizes the full-process intelligent management from geological data acquisition, mining area determination to mining point adjustment and drilling speed optimization by integrating multiple functional modules. First, through the distribution map drawing module, the system can accurately obtain and visualize geological data to help determine the mining area; second, the preliminary determination module of the mining point calculates the mining reliability index in combination with geological features and provides reliable suggestions for vein mining points; then, the re-determination module of the mining point further optimizes the mining points in combination with environmental information, considering dynamic factors such as sea currents and wind speeds to ensure the safety and efficiency of the mining process; finally, the drilling speed determination module accurately adjusts the drilling speed by comparing historical data and the environmental impact index to avoid unstable operations caused by environmental changes. The overall system improves the accuracy of mining decisions, the safety and efficiency of operations through a data-driven approach, can better cope with the challenges under complex geological conditions, and realizes the maximization of resource utilization and the continuous optimization of the mining process.
