Description

Technical Field

[0001] The invention relates to the technical field of geological exploration, and in particular to a method for extracting geological exploration data. Background Art

[0002] Geology is a knowledge system that studies the material composition, internal structure, external characteristics, interactions between various layers and evolution history of the earth. In geological exploration, geologists need to apply geological theories to conduct in-depth research and analysis on geological structures, rock types, stratigraphic distribution, and mineral resources in order to obtain accurate geological data. With the rapid development of computer science and information technology, the method of extracting geological exploration data has also ushered in a revolutionary change. Computer technology and information technology have not only improved the speed and accuracy of data processing, but also made data storage, transmission and sharing more convenient.

[0003] However, traditional geological exploration often relies on single geological parameters and indicators, including rock hardness or formation inclination, ignoring the interaction and dynamic changes among multiple factors, resulting in incomplete and inaccurate evaluation results. Most existing technologies remain in the static evaluation stage and cannot effectively simulate the dynamic changes of geological systems, such as the impact of changes in groundwater content on geological stability and risks. Although some methods attempt to optimize the evaluation results through iterative calculations, they are often difficult to promote in practical applications due to high computational complexity and slow convergence. In addition, the visualization of geological exploration data is low, making it difficult for users to intuitively understand the evaluation results. At the same time, the lack of effective interactive means makes it impossible for users to adjust evaluation parameters and models according to actual needs. Summary of the invention

[0004] The purpose of the present invention is to provide a method for extracting geological survey data, which solves the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution, and the specific implementation steps are as follows:

[0006] Using the data collection module, collect geological data in four dimensions related to geology;

[0007] Use the data collection and processing module to input, clean and screen geological data;

[0008] Using the extraction and evaluation module, the cleaned and screened geological data are substituted into the evaluation, and the geological strength index DZQ, geological stability evaluation value DW and geological risk index DF are output;

[0009] Based on the current geological risk index DF and the n geological risk indexes DF output from the previous iteration, and using the visualization analysis module, simulate and analyze the dynamic changes of the geological system;

[0010] The extraction and assessment module includes a comprehensive geological strength assessment unit, a geological stability assessment unit and a comprehensive geological risk assessment unit;

[0011] The equipment used in the data collection module includes surveying tools, hydrogeological survey equipment and seismic exploration equipment;

[0012] The equipment used by the data collection and processing module and the extraction and evaluation module include high-performance computers, servers, and GIS software;

[0013] The equipment used by the visualization analysis module includes visualization tools of the GIS system.

[0014] Optionally, the calculation formula for the comprehensive assessment geological strength unit is as follows:

[0015] ;

[0016] in:

[0017] DZQ is the geological intensity index;

[0018] YQ is the rock hardness value;

[0019] DQ is the formation dip value, which reflects the tilt of the formation;

[0020] DS is the groundwater content, which reflects the content and abundance of groundwater in the geological body;

[0021] DM is the fault density value, which reflects the development degree and distribution density of faults in the geological body;

[0022] The comprehensive assessment of the geological strength unit is as follows:

[0023] The comprehensive geological strength of a geological area, namely the geological strength index DZQ, is comprehensively evaluated by using the four dimensions of rock hardness value YQ, formation inclination value DQ, groundwater content DS and fault density value DM of comprehensive geological survey.

[0024] Optionally, the calculation formula of the geological stability assessment unit is as follows:

[0025] ;

[0026] in:

[0027] DW is the geological stability assessment value;

[0028] DZQ×YQ reflects the combined effect of geological strength index DZQ and rock hardness value YQ on geological stability;

[0029] The assessment of the geological stability assessment unit is as follows;

[0030] Based on the geological strength index DZQ and the rock hardness value YQ obtained by the comprehensive geological strength evaluation unit output, the geological stability is evaluated by considering the interaction between the geological strength and the rock hardness, that is, the geological stability evaluation value DW.

[0031] Optionally, the calculation formula for the comprehensive assessment of geological risk units is as follows:

[0032] ;

[0033] in:

[0034] DF is the geological risk index;

[0035] (1+(DS / 100)) 2 It is a function that increases rapidly as the geological stability assessment value DW decreases, reflecting the important impact of groundwater content DS on geological risk;

[0036] The assessment of the comprehensive assessment geological risk unit is as follows;

[0037] The influence of the geological stability assessment value DW and the groundwater content DS on the geological risk is further considered, and the geological risk index DF will cyclically affect the groundwater content DS in the comprehensive assessment geological strength unit to simulate the dynamic changes of the geological system.

[0038] Optionally, the survey adjustment steps based on the geological risk index DF output by the comprehensive geological risk assessment unit are as follows:

[0039] S1, using the extraction and evaluation module to extract the n geological risk indexes DF outputted in the previous iteration, and draw a line graph with the current geological risk index DF using the visualization analysis module to observe the change trend of the geological risk index DF;

[0040] S2. If n geological risk indices DF show an upward trend, it means that the geological risk is increasing. When the groundwater content DS is reduced, the impact of groundwater on geological stability is reduced, thereby reducing the geological risk;

[0041] S3. If the n geological risk indexes DF show a downward trend, it means that the geological risk is decreasing, and when the value of groundwater content DS is increased, the geological stability is maintained;

[0042] S4. If n geological risk indices DF show a fluctuating trend, it indicates that the geological risk is in an unstable state. It is necessary to investigate the change rate, fluctuation amplitude and dynamic response factors of the geological risk index DF and adjust the groundwater content DS according to the model prediction results.

[0043] Optionally, the specific presentation of the change trend of the geological risk index DF in the linear graph is as follows;

[0044] If n geological risk indices DF show an upward trend, the line graph will show an upward sloping curve;

[0045] If the n geological risk indexes DF show a downward trend, the line graph will show a downward sloping curve;

[0046] If n geological risk indices DF show a fluctuating trend, the line graph will show a curved wave trend with amplitude changes.

[0047] Optionally, the slope of the line graph can reflect the rate of change of the geological risk index DF. The larger the slope, the faster the change of the geological risk index DF is, and the more drastic the change of the geological risk is.

[0048] The fluctuation range of the line graph reflects the stability of the geological risk index DF. The larger the fluctuation range, the more unstable the change of geological risk.

[0049] Compared with the prior art, the present invention has the following beneficial effects:

[0050] 1. The present invention realizes a comprehensive assessment of geological strength by comprehensively considering four dimensions, namely rock hardness, formation inclination, groundwater content and fault density, through a geological stability assessment unit. This multi-factor comprehensive assessment method can more accurately reflect the complexity and diversity of geological systems.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Regarding this geological exploration data extraction method, it is different from the existing traditional geological exploration. The existing traditional geological exploration often relies on a single geological parameter and indicator, ignoring the interaction and dynamic changes among multiple factors, resulting in the evaluation results being not comprehensive and accurate, and unable to effectively simulate the dynamic change process of the geological system. The calculation complexity is high and the convergence speed is slow. In addition, the visualization of geological exploration data is low, and it is difficult for users to intuitively understand the evaluation results. At the same time, there is a lack of effective interactive means. This algorithm unit effectively solves the problems and shortcomings of the existing technology through multi-factor comprehensive evaluation, dynamic simulation and iterative optimization, reduction of calculation complexity, and enhancement of visualization and interactivity. Optimization innovation provides a more scientific, comprehensive and accurate basis for geological engineering design and decision-making.

[0061] For examples, see Figures 1 to 4 , this implementation provides a method for extracting geological exploration data, and the specific implementation steps are as follows:

[0062] Using the data collection module, collect geological data in four dimensions related to geology;

[0063] Use the data collection and processing module to input, clean and screen geological data;

[0064] Using the extraction and evaluation module, the cleaned and screened geological data are substituted into the evaluation, and the geological strength index DZQ, geological stability evaluation value DW and geological risk index DF are output;

[0065] Based on the current geological risk index DF and the n geological risk indexes DF output from the previous iteration, and using the visualization analysis module, simulate and analyze the dynamic changes of the geological system;

[0066] The extraction assessment module includes a comprehensive assessment unit for geological strength, a geological stability assessment unit and a comprehensive assessment unit for geological risks;

[0067] The equipment used in the data collection module includes surveying tools, hydrogeological survey equipment and seismic exploration equipment;

[0068] The equipment used in the data collection and processing module and the extraction and evaluation module include high-performance computers, servers, and GIS software;

[0069] The equipment used in the visualization analysis module includes visualization tools of the GIS system.

[0070] In this embodiment, the system reduces the computational complexity and enhances the optimization innovation in visualization and interactivity through the mutual cooperation of three algorithm units. The three operation results of DZQ, DW and DF are combined to form a complete geological exploration data extraction and analysis process, which helps geologists and engineers to more accurately evaluate geological strength, stability and risk. DZQ is a geological strength index. The geological strength index DZQ comprehensively considers the four dimensions of rock hardness value YQ, formation inclination value DQ, groundwater content DS and fault density value DM, and provides basic data for geological stability assessment and geological risk analysis. DW is a geological stability assessment value, which considers the interaction between geological strength and rock hardness, and provides an important basis for geological engineering design and risk assessment. DF is a geological risk index, which helps to more comprehensively assess geological risks and predict the future state of the geological system. The calculation results of DF can also affect the calculations fed back to DZQ and DW, so that the three algorithms of this system have a high correlation and entanglement, so that the overall algorithm system can be automatically fed back and optimized according to actual conditions to be closer to reality.

[0071] See also Figures 1 to 4 , the calculation formula for comprehensive evaluation of geological strength unit is as follows:

[0072] ;

[0073] in:

[0074] DZQ is the geological intensity index;

[0075] YQ is the rock hardness value;

[0076] DQ is the formation dip value, which reflects the tilt of the formation;

[0077] DS is the groundwater content, which reflects the content and abundance of groundwater in the geological body;

[0078] DM is the fault density value, which reflects the development degree and distribution density of faults in the geological body;

[0079] Comprehensive Assessment The assessment of the geological strength unit is as follows:

[0080] The comprehensive geological strength of a geological area, namely the geological strength index DZQ, is comprehensively evaluated by using the four dimensions of rock hardness value YQ, formation inclination value DQ, groundwater content DS and fault density value DM of comprehensive geological survey.

[0081] In this embodiment: First, in this algorithm unit, the rock hardness value YQ is an important indicator to measure the ability of rock to resist external force damage. In geological surveys, understanding the rock hardness helps to evaluate the stability of underground projects, and rocks of different hardness correspond to different mining difficulties and costs. By measuring the rock hardness, it is possible to guide the mining plan of mineral resources, optimize the mining plan, and improve the mining efficiency;

[0082] The formation dip value DQ reflects the tilt direction and angle of the underground rock formation and is an important parameter for revealing geological structures. By measuring the formation dip, we can understand the shape, scale and distribution characteristics of the geological structure. In underground engineering construction, the formation dip has a direct impact on the stability of the project. Understanding the formation dip helps to select appropriate engineering design solutions and ensure the safety and economy of the project. In addition, changes in formation dip are often closely related to the occurrence of geological disasters. By monitoring changes in formation dip, we can predict the occurrence trend of geological disasters and provide early warning information for disaster prevention and mitigation work.

[0083] Groundwater content DS Groundwater is one of the important natural resources. By measuring groundwater content DS, the potential and distribution of groundwater resources can be evaluated, providing a scientific basis for the rational development and utilization of water resources. Groundwater content DS has an important impact on the safety of underground projects. Too high groundwater content DS will lead to instability and leakage of the project foundation. Understanding groundwater content helps to formulate corresponding waterproofing and drainage measures to ensure project safety. Groundwater content DS is also closely related to ecological environmental protection. By monitoring the changes in groundwater content DS, groundwater pollution problems can be discovered and solved in a timely manner to protect the quality and safety of the ecological environment.

[0084] Fault density DM is the structure where the rock in the crust breaks and has obvious relative displacement along the fracture surface. Fault density reflects the frequency and intensity of geological activities. By measuring fault density, we can understand the history and current status of geological activities. Faults are important controlling factors of geological disasters. Understanding fault density helps predict the occurrence trend and distribution range of geological disasters and provide a scientific basis for disaster prevention and mitigation.

[0085] In summary, the four dimensions of rock hardness value YQ, formation dip value DQ, groundwater content DS and fault density value DM are of great significance in the extraction of geological survey data. They not only provide geologists and engineers with key information on geological structure, resource distribution and potential risks, but also provide a scientific basis for the design, construction and safety management of underground projects.

[0086] The geological strength index DZQ obtained by the output of this algorithm unit not only takes into account the physical strength of the rock, but also incorporates geological elements such as formation dip, groundwater content and fault density, thus realizing a multi-dimensional comprehensive evaluation of geological strength. This comprehensive evaluation method can more comprehensively reflect the complexity and diversity of geological regions than a single indicator.

[0087] Through a specific calculation method, the geological intensity index DZQ converts geological parameters of different dimensions into a unified quantitative index, realizing a standardized assessment of geological intensity, which facilitates direct comparison and ranking between different geological regions and provides a scientific basis for geological engineering design and planning;

[0088] The value of the geological intensity index DZQ directly reflects the intensity characteristics of the geological area and points out the direction for geological exploration. During the exploration process, priority can be given to areas with lower geological intensity index DZQ values ​​because these areas may be more prone to geological disasters or have higher resource potential.

[0089] See also Figures 1 to 4 , the calculation formula of the geological stability assessment unit is as follows:

[0090] ;

[0091] in:

[0092] DW is the geological stability assessment value;

[0093] DZQ×YQ reflects the combined effect of geological strength index DZQ and rock hardness value YQ on geological stability;

[0094] The assessment of the geological stability assessment unit is as follows;

[0095] Based on the geological strength index DZQ and rock hardness value YQ obtained by comprehensive evaluation of the geological strength unit output, the geological stability is evaluated by considering the interaction between geological strength and rock hardness, that is, the geological stability evaluation value DW.

[0096] In this embodiment, firstly, the geological stability assessment value DW further introduces the consideration of rock hardness on the basis of the geological strength index DZQ, emphasizing the important influence of rock hardness on geological stability. This dual consideration makes the assessment of geological stability more comprehensive and accurate.

[0097] The assessment results of the geological stability assessment value DW provide an important basis for the subsequent geological risk assessment. By understanding the stability of the geological area, it is possible to preliminarily determine the risk of geological disasters in the area and provide a scientific basis for disaster prevention and mitigation work.

[0098] In geological engineering design, the evaluation results of the geological stability assessment value DW can be used as a reference for design parameters. For example, in the design of tunnels, bridges and other projects, it is necessary to fully consider the geological stability factors to ensure the safety and stability of the project.

[0099] See also Figures 1 to 4 , the calculation formula for comprehensive assessment of geological risk units is as follows:

[0100] ;

[0101] in:

[0102] DF is the geological risk index;

[0103] (1+(DS / 100)) 2 It is a function that increases rapidly as the geological stability assessment value DW decreases, reflecting the important impact of groundwater content DS on geological risk;

[0104] The overall assessment of the geological risk unit is as follows;

[0105] The influence of geological stability assessment value DW and groundwater content DS on geological risk is further considered, and the geological risk index DF will cyclically affect the groundwater content DS in the comprehensive assessment geological intensity unit to simulate the dynamic changes of the geological system.

[0106] In this embodiment, the algorithm unit first calculates DW*(1+(DS / 100)) 2 This calculation part first calculates a nonlinear relationship between the geological stability assessment value DW and the groundwater content DS. Specifically, (1+(DS / 100)) 2 It is a function that increases rapidly as the geological stability assessment value DW decreases, reflecting the important influence of groundwater content on geological risk. When the groundwater content DS is low, the function value is large, thereby increasing the geological risk. On the contrary, when the groundwater content DS is high, the function value approaches 1, and the influence on geological risk is small.

[0107] The product of the geological stability assessment value DW and this nonlinear function combines the influence of geological stability and groundwater content to jointly assess geological risks;

[0108] In this embodiment, the geological risk index DF realizes the dynamic assessment of geological risk by introducing the dynamic influence mechanism of the geological stability assessment value DW and the groundwater content DS. This dynamic assessment method can reflect the impact of changes in geological conditions on geological risks in real time, thereby improving the timeliness and accuracy of risk assessment.

[0109] The geological risk index DF not only takes into account the two main factors of geological stability assessment value DW and groundwater content DS, but also includes comprehensive consideration of other geological, meteorological and human activity factors. This multi-factor comprehensive consideration makes the geological risk assessment more comprehensive and detailed.

[0110] The assessment results of the geological risk index DF provide important decision-making support for the early warning, prevention and response of geological disasters. By understanding the distribution and changing trends of geological risks, targeted disaster prevention and mitigation measures and emergency plans can be formulated to reduce the impact of geological disasters on human society and the natural environment.

[0111] See also Figures 1 to 4 , the survey adjustment steps of the geological risk index DF output based on the comprehensive assessment of geological risk unit are as follows:

[0112] S1. Using the extraction and evaluation module, extract the n geological risk indexes DF outputted in the previous iteration, and draw a line graph with the current geological risk index DF using the visualization analysis module to observe the change trend of the geological risk index DF;

[0113] S2. If n geological risk indices DF show an upward trend, it means that the geological risk is increasing. When the groundwater content DS is reduced, the impact of groundwater on geological stability is reduced, thereby reducing the geological risk;

[0114] S3. If the n geological risk indexes DF show a downward trend, it means that the geological risk is decreasing, and when the value of groundwater content DS is increased, the geological stability is maintained;

[0115] S4. If the n geological risk indexes DF show a fluctuating trend, it indicates that the geological risk is in an unstable state. It is necessary to investigate the change rate, fluctuation amplitude and dynamic response factors of the geological risk index DF and adjust the groundwater content DS according to the model prediction results.

[0116] The specific presentation of the changing trend of geological risk index DF in the linear graph is as follows;

[0117] If n geological risk indices DF show an upward trend, the line graph will show an upward sloping curve;

[0118] If the n geological risk indexes DF show a downward trend, the line graph will show a downward sloping curve;

[0119] If n geological risk indices DF show a fluctuating trend, the line graph will show a curvilinear wave trend with amplitude changes;

[0120] The slope of the line graph can reflect the rate of change of the geological risk index DF. The larger the slope, the faster the change of the geological risk index DF and the more drastic the change of geological risk.

[0121] The fluctuation range of the line graph reflects the stability of the geological risk index DF. The larger the fluctuation range, the more unstable the change of geological risk.

[0122] In this embodiment, in order to intuitively display the cyclic influence mechanism and visualization effect of the comprehensive geological risk assessment unit on the comprehensive geological strength assessment unit, the algorithm unit can draw a dynamic line graph, in which the horizontal axis represents the number of iterations and the vertical axis represents the change of the geological risk index DF. As the iteration process proceeds, the vertical axis will be adjusted in real time according to the assessment results of the geological risk index DF.

[0123] Before the iteration begins, the initial geological risk index DF and the initial geological intensity index DZQ value calculated based on the comprehensive assessment of geological risk units are set. These two values ​​are represented by starting points in the figure;

[0124] As the iterative process proceeds, each iteration will calculate a new geological risk index DF value based on the comprehensive assessment of the geological risk unit, and then adjust the geological risk index DF based on the geological risk index DF value, for example, through a certain mapping and adjustment function, which will affect the calculation of the geological intensity index DZQ. The change in the geological intensity index DZQ value will be represented by a new point in the figure and connected into a trend line;

[0125] In order to more intuitively show the changing trend of the geological intensity index DZQ value and the geological risk index DF, animation and interactive charts can be used to dynamically display the iteration process. As the number of iterations increases, the trend line will gradually form and show the changing law of the geological intensity index DZQ value and the geological risk index DF.

[0126] In order to analyze the sensitivity of different parameters to the cyclic impact mechanism, multiple trend lines and scatter plots can be added to the graph, which respectively represent the changes in the geological intensity index DZQ value and the geological risk index DF under different initial geological risk index DF, different mapping / adjustment functions or different geological conditions. By comparing and analyzing these trend lines and scatter plots, we can gain a deep understanding of the interaction between the parameters and their impact on the overall assessment results;

[0127] Trend judgment: The rising and falling trends of the line graph can intuitively reflect the changing trend of the geological risk index DF value. If the curve continues to rise, it means that the geological risk is increasing. If the curve continues to fall, it means that the geological risk is decreasing. If the curve fluctuates greatly, it means that the geological risk is in an unstable state.

[0128] Change rate: The slope of the line graph can reflect the change rate of the geological risk index DF value. The larger the slope, the faster the change of the geological risk index DF value, and the more drastic the change of geological risk;

[0129] Fluctuation range: The fluctuation range of the line graph can reflect the stability of the geological risk index DF value. The larger the fluctuation range, the more unstable the change of geological risk is, and the closer attention needs to be paid;

[0130] Outlier detection: In the line graph, if a geological risk index DF value is significantly different from other values, that is, an outlier, it means that some mutation and abnormal events have occurred in the geological system, which requires further investigation and analysis;

[0131] Predicting future trends: Although the line chart itself cannot directly predict the future geological risk index DF value and geological risk trend, it can provide us with a reference framework to evaluate the possibility of future geological risks in combination with other geological data and model prediction results;

[0132] In the cyclic impact mechanism of this embodiment, the evaluation result of the geological risk index DF will be fed back to the groundwater content DS parameter, thereby affecting the calculation of the geological strength index DZQ. This real-time feedback mechanism enables the evaluation of geological strength to be dynamically adjusted as geological conditions change, thereby improving the accuracy and timeliness of the evaluation.

[0133] Through the circular influence mechanism, a close linkage is formed between different geological parameters. This linkage helps to enhance the stability and robustness of the entire assessment system, enabling the system to maintain stable assessment performance when facing complex and changeable geological conditions, thereby enhancing system stability.

[0134] The circular impact mechanism enables geological exploration and risk assessment work to more accurately locate key areas and key links, which helps to optimize resource allocation, invest limited exploration and disaster prevention resources where they are most needed, and improve resource utilization efficiency.

[0135] In summary, in the specific implementation process, using computer-aided drawing of a line graph of the geological risk index DF value is a very useful method that can help us better understand and evaluate the changing trend of geological risks.
