Description

Technical Field

[0001] The present invention relates to the field of mining technology, and in particular to a GIS-based ore mining path planning method and system under complex geological conditions. Background Art

[0002] With the increasing demand for mineral resources, especially in the field of seabed mining, traditional mining methods are facing more and more challenges. The complex geological conditions, environmental factors and limitations of mining technology of seabed veins often lead to instability and inefficiency of mining operations. The exploration and mining of seabed veins not only need to consider geological factors such as the depth and distribution of the ore body, but also need to comprehensively evaluate external factors such as ocean currents and wind speeds, as well as the potential impact of mining operations on the ecological environment. Therefore, how to plan the optimal mining path in a complex seabed 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 mining path planning methods mainly rely on static geological exploration data, and often fail to fully consider multi-dimensional factors such as the location of the ore vein and changes in the marine environment, resulting in inaccuracy in path planning, which in turn affects the efficiency and reliability of mining operations. At the same time, the impact of environmental factors such as ocean currents and offshore wind speeds are often ignored in operations. These factors have an important impact on the safety of mining, drilling speed, etc. 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 GIS-based mineral mining path planning method and system under complex geological conditions to solve the problems of inaccurate and inefficient traditional mining path planning methods, which affect safety and operation speed. Summary of the invention

[0005] In view of this, the present invention proposes a GIS-based mineral vein excavation path planning method and system under complex geological conditions, aiming to solve the problem that traditional mining path planning methods are inaccurate and inefficient, affecting safety and operation speed.

[0006] The present invention proposes a GIS-based ore mining path planning method under complex geological conditions, comprising:

[0008] Using GIS tools to mark the geological features of the mining area, calculating the mining reliability index based on the geological features, and preliminarily determining the mining point of the ore vein based on the mining reliability index; wherein the geological features include fault thickness, marine layer thickness, rock layer thickness and rock layer hardness;

It is judged whether to correct the initial value of the drilling speed according to the environmental impact index. If the judgment result is that correction is required, the initial value of the drilling speed is corrected according to the environmental impact index to obtain the final value of the drilling speed.

[0011] Furthermore, the process of marking the geological features of the mining area by using a GIS tool, calculating the mining reliability index according to the geological features, and preliminarily determining the mining point of the ore vein according to the mining reliability index includes:

[0012] Divide the mining area into a plurality of grid areas, and number each of the grid areas; wherein the areas of the grid areas are the same;

[0013] The center point of each grid area is used as a pre-mining point of the ore vein, and the vertical path from the pre-mining point of the ore vein to the ore vein is used as a pre-mining path;

[0014] The average hardness of the rock layer of the pre-mining path is calculated, the maximum value of the mining reliability index and the maximum value of the geological layer thickness are set, and the mining reliability index of each pre-mining point of the ore vein is calculated according to the geological characteristics of the pre-mining path by the following formula:

[0015] Ri=Rmax*(1−α1*hf / hmax−α2*hr / hmax−α3*ho / hmax)*(1−β / kr);

[0016] 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 represent the influence value of the fault thickness, the rock layer thickness and the ocean layer thickness respectively, and β represents the influence value of the rock layer hardness; among which, the value ranges of α1, α2, α3 and β are all 0-1;

[0017] A mining reliability index standard value is set, and a pre-mining point corresponding to a mining reliability index greater than or equal to the reliability index standard value is preliminarily determined as a vein mining point.

[0018] Furthermore, the collecting of environmental information and calculating the environmental impact index according to the environmental information includes:

[0020] Rh=|(Vl-Vlmax) / Vlmax|+|(Vf-Vfmax) / Vfmax|;

[0021] In the above formula, Rh represents the environmental impact index, Vl represents the current current speed, Vlmax represents the safe maximum value of the current speed, Vf represents the offshore wind speed, and Vfmax represents the safe maximum value of the offshore wind speed.

[0024] If the environmental impact index is less than the maximum environmental impact index, it is determined that the initially determined mineral vein mining point needs to be adjusted.

[0025] Furthermore, if it is determined that the mining point of the mineral vein needs to be adjusted, the comprehensive index is calculated according to the mining reliability index and the environmental impact index, including:

[0026] The comprehensive index is calculated according to the mining reliability index and the environmental impact index by the following formula:

[0027] Z = a*Ri-b*Rh;

[0028] 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, and b represents the weight coefficient of the environmental impact index, where the value ranges of a and b are both 0-1.

[0029] Furthermore, the re-determining of the mining point of the mineral vein according to the comprehensive index includes:

[0030] Arrange the comprehensive indexes of the mineral vein mining points in descending order;

[0031] 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.

[0032] Furthermore, the method of comparing the comprehensive index of the re-determined mineral vein mining point with the comprehensive index of the historical mineral vein mining point and determining the initial value of the drilling speed according to the comparison result includes:

[0033] If the same comprehensive index as the final mining point exists in the historical data, the final value of the drilling speed of the historical data is determined as the initial value of the drilling speed;

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

[0035] Presetting a first difference and a second difference, wherein the first difference is smaller than the second difference;

[0036] If the index difference is less than the first difference, the first speed initial value is used as the drilling speed initial value;

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

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

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

[0040] Furthermore, judging whether to modify the initial value of the drilling speed according to the environmental impact index includes:

[0041] If the environmental impact index exceeds the historical environmental impact index of all historical mining points, it is determined that the initial value of the drilling speed needs to be corrected;

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

[0043] Furthermore, if the judgment result is that correction is required, the initial value of the drilling speed is corrected according to the environmental impact index to obtain the final value of the drilling speed, including:

[0044] Calculating the impact difference between the environmental impact index and the maximum value of the historical environmental impact index, and adjusting the initial value of the drilling speed according to the impact difference;

[0045] Setting a first impact difference and a second impact difference; wherein the first impact difference is smaller than the second impact difference;

[0046] If the impact difference is less than the first impact difference, adjusting the initial value of the drilling speed by a first correction coefficient;

[0047] If the impact difference is greater than or equal to the first impact difference, and less than or equal to the second impact difference, adjusting the drilling speed by a second correction coefficient;

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

[0049] The value range of the correction coefficient is 1>first correction coefficient>second correction coefficient>third correction coefficient>0, and the final value of the drilling speed is the product 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 acquiring 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 seabed veins, marine faults, depth distribution and rock layers. This process preliminarily determines the mining points of the veins by marking and calculating the mining reliability index through GIS tools, effectively avoiding human misjudgment and wrong planning. Secondly, the environmental impact index is calculated in combination with the real-time collected environmental information (such as ocean current speed and offshore wind speed), and the selection of the vein mining points is further optimized to ensure the safety and efficiency of the mining operation. In addition, by comparing the comprehensive index of the vein mining point 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 waste of resources. In summary, the method ensures the scientificity, sustainability and efficiency of the vein mining operation by integrating geological, environmental and operating parameters, thereby significantly improving the mining efficiency of mineral resources and the level of ecological environmental protection.

The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

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

[0062] S100, obtaining geological data of the region, inputting the geological data into a GIS system, constructing a three-dimensional spatial distribution map of the region, and determining a mining area according to the three-dimensional spatial distribution map; wherein the mining area is an area above the area where the seabed mineral veins are located, and the geological data includes the distribution of seabed mineral veins, the distribution of marine faults, the distribution of marine depths, and the thickness of rocks;

[0063] S200, using GIS tools to mark the geological features of the mining area, calculating the mining reliability index based on the geological features, and preliminarily determining the mining points of the ore veins based on the mining reliability index; wherein the geological features include fault thickness, marine layer thickness, rock layer thickness, and rock layer hardness;

[0064] S300, collecting environmental information, calculating an environmental impact index based on the environmental information, judging whether it is necessary to adjust the mining point of the ore vein according to the environmental impact index, and if it is judged that the mining point of the ore vein needs to be adjusted, calculating a comprehensive index based on the mining reliability index and the environmental impact index, and re-determining the mining point of the ore vein according to the comprehensive index; wherein the environmental information includes the ocean current speed and the offshore wind speed;

[0065] S400, comparing the comprehensive index of the re-determined ore vein mining point with the comprehensive index of the historical ore vein mining point, determining the initial value of the drilling speed according to the comparison result, judging 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 needed, correcting 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, the present invention can accurately determine the mining area by acquiring regional geological data and constructing a three-dimensional spatial distribution map, and comprehensively consider key factors such as submarine veins, marine faults, depth distribution and rock layers. This process uses GIS tools to mark and calculate the mining reliability index, preliminarily determine the vein mining point, and effectively avoids human misjudgment and wrong planning. Secondly, combined with real-time collected environmental information (such as ocean current speed and offshore wind speed), the environmental impact index is calculated to 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 point 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 operating parameters, thereby significantly improving the mining efficiency of mineral resources and the level of ecological environmental protection.

[0067] In some embodiments of the present application, the geological features of the mining area are marked by a GIS tool, the mining reliability index is calculated according to the geological features, and the mining point of the ore vein is preliminarily determined according to the mining reliability index, including:

[0068] Divide the mining area into a number of grid areas, and number each grid area; wherein the areas of the grid areas are the same;

[0069] The center point of each grid area is used as the pre-mining point of the ore vein, and the vertical path from the pre-mining point to the ore vein is used as the pre-mining path;

[0070] Calculate the average hardness of the rock layer of the pre-mining 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 pre-mining point of the ore vein according to the geological characteristics of the pre-mining 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 represent the influence value of the fault thickness, the rock layer thickness and the ocean layer thickness respectively, and β represents the influence value of the rock layer hardness; among which, the value ranges of α1, α2, α3 and β are all 0-1;

[0073] A standard value of the mining reliability index is set, and the pre-mining points corresponding to the mining reliability index that is greater than or equal to the standard value of the reliability index are preliminarily determined as the vein mining points.

[0074] It is understandable that the present invention effectively achieves the precise preliminary determination of the mining points of the mineral veins 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, marine layer thickness, and rock layer hardness, the reliability index of each mineral vein pre-mining point is comprehensively calculated, and reliable mining points are screened out by setting standard values, thereby improving the scientificity and safety of the mining path. This method can not only optimize the positioning of mineral veins under complex geological conditions, reduce risks and waste of resources, but also dynamically adjust the mining strategy to ensure the efficient mining and long-term stability of mineral resources.

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

[0076] The maximum safety value of the current speed and the maximum safety value of the offshore wind speed are preset, and the environmental impact index is calculated by 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 current speed, Vlmax represents the safe maximum value of the current speed, Vf represents the offshore wind speed, and Vfmax represents the safe maximum value of the offshore wind speed.

[0079] In some embodiments of the present application, judging whether it is necessary to adjust the mining point of the mineral vein according to the environmental impact index 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 determined that there is no need to adjust the initially determined mining point of the mineral vein;

[0081] If the environmental impact index is less than the maximum environmental impact index, it is judged that the initially determined mineral vein mining point needs to be adjusted.

[0082] It is understandable that the present invention effectively evaluates the impact of environmental factors on the mining point of the mineral vein by calculating the environmental impact index of the ocean current speed and the offshore wind speed. By setting the safe maximum values ​​of the ocean current speed 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 mining operations. This method not only improves the scientific nature of mining decisions, but also enhances the ability to respond to environmental changes, helps to reduce environmental damage, and ensures the sustainable mining of mineral resources.

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

[0084] The comprehensive index is calculated based on 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, and 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 calculates a comprehensive index by combining the mining reliability index and the environmental impact index, thereby achieving a comprehensive assessment of the mining points of the mineral vein. By setting the weight coefficient, the influence of mining reliability and environmental impact is balanced, making the final decision more scientific and reasonable. If the environmental impact is large and the impact exceeds expectations, the adjustment of the comprehensive index can reflect this change in a timely manner, thereby guiding the adjustment of the mining point. This method can effectively integrate geological conditions and environmental factors, optimize mining decisions, improve the safety and efficiency of mining operations, reduce environmental risks, and ensure the efficient and sustainable mining of mineral resources.

[0088] In some embodiments of the present application, when the mining point of the mineral vein is determined again according to the comprehensive index, it includes:

[0089] Arrange the comprehensive indexes of the mineral 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, the final selected mining point is ensured to be the best. 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 waste of resources, thereby improving the overall efficiency and safety of mining, and ensuring the scientificity and sustainability of the operation.

[0092] In some embodiments of the present application, the comprehensive index of the re-determined mineral vein mining point is compared with the comprehensive index of the historical mineral vein mining point, and the initial value of the drilling speed is determined according to the comparison result, including:

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

[0094] Otherwise, set the 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] Presetting a first difference and a second difference, wherein the first difference is smaller than the second difference;

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

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

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

[0099] Among them, the first speed initial value < the second speed initial value < the third speed initial value.

[0100] It is understandable that by comparing the comprehensive index of the final mining point with the historical data, the initial value of the drilling speed is adjusted according to the index difference, so as to accurately determine the drilling speed according to the actual situation of the vein mining point. This method takes into account the similarity between historical data and new mining points, and effectively avoids the problem of inaccurate drilling speed caused by lack of reference data. By setting different initial speed value ranges to ensure adaptability to operations under different conditions, the adjustment process of the drilling speed is optimized, and the efficiency and safety of mining operations 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, judging whether to modify the initial value of the drilling speed according to the environmental impact index includes:

[0102] If the environmental impact index exceeds the historical environmental impact index of all historical mining sites, it is judged that the initial value of the drilling speed needs to be corrected;

[0103] If the environmental impact index is less than or equal to the historical environmental impact index of all historical mineral mining points, it is determined that there is no need to correct the initial value of the drilling speed.

[0104] In some embodiments of the present application, if the judgment result is that correction is required, the initial value of the drilling speed is corrected according to the environmental impact index to obtain the final value of the drilling speed, including:

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

[0106] Setting a first impact difference and a second impact difference; wherein the first impact difference is smaller than the second impact difference;

[0107] If the impact difference is less than the first impact difference, the initial value of the drilling speed is adjusted by 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, the drilling speed is adjusted by the second correction coefficient;

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

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

[0111] It is understandable that by comparing the environmental impact index with historical data, the initial value of the drilling speed can be 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 determine and correct the drilling speed to adapt to more complex environmental factors. By setting the impact difference and correction coefficient, the method can make fine adjustments based on specific environmental changes, thereby effectively optimizing the drilling speed and avoiding waste of resources 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 ensure the stability and long-term sustainability of the operation process.

[0112] On the other hand, see Figure 2 As shown, the present application also provides a GIS-based mineral vein excavation path planning system under complex geological conditions, which is used to apply the GIS-based mineral vein excavation path planning method under complex geological conditions, including:

[0113] A distribution map drawing module is configured to obtain geological data of a region, input the geological data into a GIS system, construct a three-dimensional spatial distribution map of the region, and determine a mining area based on the three-dimensional spatial distribution map; wherein the mining area is an area above the area where the seabed mineral veins are located, and the geological data includes the distribution of seabed mineral veins, the distribution of marine faults, the distribution of marine depths, and the thickness of rocks;

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

[0115] The mining point re-determination module is configured to collect environmental information, calculate an environmental impact index based on the environmental information, determine whether the mining point of the ore vein needs to be adjusted based on the environmental impact index, and if it is determined that the mining point of the ore vein needs to be adjusted, calculate a comprehensive index based on the mining reliability index and the environmental impact index, and re-determine the mining point of the ore vein based on the comprehensive index; wherein the environmental information includes ocean current speed and offshore wind speed;

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

[0117] It is understandable that the mining path planning system integrates multiple functional modules to achieve intelligent management of the entire process from geological data acquisition, mining area determination to mining point adjustment and drilling speed optimization. First, through the distribution map drawing module, the system can accurately obtain and visualize geological data to help determine the mining area; secondly, the mining point preliminary determination module calculates the mining reliability index based on geological characteristics and provides reliable mining point suggestions; then, the mining point re-determination module further optimizes the mining point based on environmental information, taking into account dynamic factors such as ocean 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 environmental impact indexes to avoid unstable operations caused by environmental changes. The overall system improves the accuracy of mining decisions, the safety and efficiency of operations through data-driven methods, and can better cope with challenges under complex geological conditions, maximize resource utilization and continuously optimize the mining process.
