Next, according to the purpose and needs of the evaluation, a suitable evaluation method and indicator system are selected to conduct a quantitative evaluation of the underground space. The evaluation indicators include space utilization, resource development difficulty, resource economic value and other aspects. Finally, based on the evaluation results, a corresponding mine underground space development and utilization plan or program is formulated.

[0046] In order to better understand the purpose of the present invention, the present invention is described in further detail below.

[0047] The present invention provides an evaluation and analysis management system for underground space in a mine, comprising:

[0048] A data acquisition unit acquires basic data of underground space of a mine, including mine coordinate information, mine construction information, mine production information, geological structure, rock properties and groundwater conditions, and substitutes the basic data of underground space of a mine into a preset digital twin model to obtain basic image data of mine terrain space;

[0049] The data acquisition unit is used in the mine underground space assessment and analysis management system in the present invention. Its main responsibility is to obtain the basic data of the mine underground space and substitute the data into the preset digital twin model to generate the basic image data of the mine terrain space. The following is the detailed workflow of the data acquisition unit:

[0050] The data acquisition unit first collects the basic data of the underground space of the mine, including but not limited to mine coordinate information, mine construction information, mine production information, geological structure, rock properties and groundwater conditions.

[0051] Before the collected data is substituted into the digital twin model, the data acquisition unit will preprocess the data. The preprocessing steps include data cleaning, format conversion, missing value processing, etc. to improve the accuracy and consistency of the data. The preprocessing process also includes initializing the preset digital twin model, loading the necessary model components and library files, and preparing for data substitution and model operation.

[0052] The pre-processed basic data of the underground space of the mine is input into the preset digital twin model. The digital twin model is a highly simulated virtual model that can simulate and reflect the actual conditions of the underground space of the mine. The model starts running after receiving the data and generates basic image data of the mine terrain space based on the input data. The basic image data generated by the digital twin model includes two-dimensional display of the underground space information of the mine and three-dimensional image display of the underground space information of the mine. The image data intuitively displays the key information of the topography, geological structure, mine layout, etc. of the underground space of the mine, providing important visual support for subsequent evaluation and analysis. Through the work of the data acquisition unit, the present invention can obtain comprehensive and accurate basic data of the underground space of the mine, and convert it into intuitive and easy-to-understand image data, providing a solid foundation for subsequent evaluation and analysis. At the same time, the application of the digital twin model also makes the evaluation and analysis process more intelligent and efficient.

[0053] The data acquisition unit collects the natural environment data of the coordinate position of the mine according to the mine coordinate information to obtain the natural environment data of the mine, the natural environment data of the mine includes the weather information and natural disaster information of the coordinate position of the mine, and receives the real-time construction information and the real-time production information of the underground space of the mine;

[0054] The data acquisition unit is used in the mine underground space assessment and analysis management system of the present invention and is responsible for collecting various data related to the mine underground space, providing comprehensive information support for subsequent assessment and analysis. The following are the specific work contents of the data acquisition unit:

[0055] The data acquisition unit first receives the coordinate information of the mine, which is the basis for subsequent data collection. Based on the coordinate information of the mine, the data acquisition unit will further collect the natural environment data of the coordinate location of the mine. The data includes but is not limited to weather information (such as temperature, humidity, rainfall, etc.) and natural disaster information (such as earthquakes, floods, landslides, etc.) at the location of the mine. Natural environment data are crucial for assessing the safety of underground space in mines because they directly affect the production safety and stability of mines.

[0056] The data acquisition unit is also responsible for receiving real-time construction information and production information from the underground space of the mine. The information reflects the current operation status and production situation of the mine and is an important basis for evaluating the operation efficiency and safety of the mine. Real-time construction information includes excavation progress, support conditions, ventilation conditions, etc.; while real-time production information includes ore output, equipment operation status, personnel operation status, etc.

[0057] The collected natural environment data, real-time construction information, and production information will be sorted out by the data collection unit. In this process, redundant and erroneous information will be removed to improve the accuracy and reliability of the data. The sorted data will be stored in a designated database for subsequent data analysis and evaluation.

[0058] Through the work of the data acquisition unit, the present invention can obtain relevant data of the underground space of the mine in real time and comprehensively, providing strong data support for subsequent evaluation and analysis. The data not only covers the natural environment conditions of the location of the mine, but also includes the current construction and production conditions of the mine, providing a comprehensive perspective for the comprehensive evaluation of the safety of the underground space of the mine.

[0059] An image modification unit substitutes the real-time construction information and the real-time production information of the underground space of the mine into the basic image data of the mine terrain space through a preset digital twin model, updates the image data in the basic image data of the mine terrain space, and obtains the updated basic image data of the mine terrain space;

[0060] The image modification unit in the present invention is responsible for substituting the real-time construction information and production information of the underground space of the mine into the basic image data of the underground space of the mine through the preset digital twin model, so as to update the image data in real time. The following is the specific workflow and function of the image modification unit:

[0061] The image modification unit first receives real-time construction information and production information from the underground space of the mine. The information includes but is not limited to excavation progress, support conditions, ore production, equipment operation status, etc., which reflect the current operation status and production status of the mine. The received real-time information will go through a preprocessing step to improve its accuracy and consistency. Preprocessing includes data cleaning, format conversion, outlier processing, etc.

[0062] The pre-processed real-time information will be substituted into the preset digital twin model. The digital twin model is a highly simulated virtual model that can simulate and reflect the actual conditions of the underground space of the mine. The digital twin model updates the basic image data of the mine terrain space based on the real-time information substituted in. This process includes adjusting the parameters and attributes in the image data to reflect the latest construction and production conditions of the underground space of the mine.

[0063] The updated mine terrain spatial basic image data will contain the latest construction progress, production status and other information, providing the latest data support for subsequent evaluation and analysis. After the update is completed, the digital twin model will output the updated mine terrain spatial basic image data. The data will be transmitted to other parts of the system for subsequent evaluation and analysis.

[0064] Through the work of the image modification unit, the present invention can achieve real-time updating of the mine underground space image data, so that the data based on the evaluation and analysis is the latest. This helps to improve the accuracy and efficiency of the evaluation and analysis, and provides strong support for the safe production and efficient operation of the mine.

[0065] The image acquisition unit monitors the mine natural environment data and the mine underground space basic data. When the mine natural environment data and the mine underground space basic data exceed the preset safety value, the mine natural environment data and the mine underground space basic data exceeding the preset safety value are substituted into the updated mine underground space basic image data to obtain the real-time mine terrain space basic image data to be evaluated;

[0066] The image acquisition unit in the present invention undertakes the monitoring and data integration tasks, is responsible for continuously monitoring the natural environment data of the mine and the basic data of the underground space of the mine, and when the data exceeds the preset safety value, substitutes the abnormal data into the updated basic image data of the mine terrain space, thereby generating real-time basic image data of the mine terrain space to be evaluated. The following is the specific workflow and function of the image acquisition unit:

[0067] The image acquisition unit will first continuously monitor the natural environment data of the mine (such as temperature, humidity, rainfall, earthquakes, floods, landslides, etc.) and the basic data of the underground space of the mine (such as geological structure, rock properties, groundwater conditions, etc.). The monitoring is real-time, aiming to improve the system's ability to quickly capture any data changes that affect the safety of the underground space of the mine.

[0068] For each piece of data monitored, the image retrieval unit will compare it with the preset safety value. The preset safety value is set based on professional knowledge and historical data to improve the safety and stability of the underground space of the mine.

[0069] When the monitored data exceeds the preset safety value, the image retrieval unit will regard the abnormal data as important information and prepare to substitute it into the updated mine terrain spatial basic image data. This process includes identifying the type, location and impact range of the abnormal data.

[0070] The image retrieval unit substitutes the mine natural environment data and mine underground space basic data that exceed the preset safety value into the mine underground space basic image data previously updated by the image modification unit. This substitution process aims to reflect the latest data that affects the safety of the mine underground space in the image data, thereby generating real-time mine underground space basic image data to be evaluated.

[0071] After the above processing, the image retrieval unit will generate real-time basic image data of the underground space of the mine to be evaluated, which contains abnormal data. It not only includes the latest status of the underground space of the mine, but also highlights the existing safety hazards or risk areas, providing important data support for subsequent evaluation and analysis.

[0072] Through the work of the image retrieval unit, the present invention can improve the system's ability to quickly capture changes and generate corresponding image data when the safety of the underground space of the mine changes, providing timely and accurate information support for subsequent evaluation and analysis. This helps to improve the efficiency and accuracy of the evaluation and analysis of the underground space of the mine, and provides a strong guarantee for the safe production and operation of the mine.

[0073] The evaluation and analysis unit configures coordinate points for the real-time basic spatial image data of the mine terrain to be evaluated, obtains a real-time spatial coordinate data set of the mine terrain to be evaluated, receives the coordinates of the mine construction and production safety hazard area, matches the coordinates of the mine construction and production safety hazard area with the coordinates of the mine construction and production safety hazard area, if the match is unsuccessful, the safety hazard area is not within the scope of the real-time basic spatial image data of the mine terrain to be evaluated, corrects the real-time basic spatial image data of the mine terrain to be evaluated, obtains the corrected real-time basic spatial image data of the mine terrain to be evaluated, retrieves the natural environment data of the coordinate position of the real-time mine in the database, compares the natural environment data of the coordinate position of the real-time mine with the corrected real-time basic spatial image data of the mine terrain to be evaluated, and evaluates through a preset mine underground space evaluation model to obtain the evaluation result of the mine underground space.

[0074] The evaluation and analysis unit in the present invention is responsible for processing and analyzing the real-time basic image data of the underground space of the mine to be evaluated, so as to generate a comprehensive evaluation result of the underground space of the mine. The following is the specific workflow and function of the evaluation and analysis unit:

[0075] The evaluation and analysis unit first configures coordinate points for the real-time spatial basic image data of the mine terrain to be evaluated. This process is designed to mark key locations, boundaries or feature points in the image data and assign a unique coordinate identifier to each point. Through the coordinate point configuration, the evaluation and analysis unit can more accurately locate and analyze each part of the image data, providing a basis for subsequent data matching and evaluation.

[0076] The evaluation and analysis unit receives the coordinates of the potential safety hazard areas from the mine construction and production. It then matches the coordinates of the potential safety hazard areas with the coordinate points in the real-time spatial basic image data of the mine terrain to be evaluated. The purpose of the matching is to determine whether the potential safety hazard area is within the range of the image data currently being evaluated.

[0077] If the match is unsuccessful, it means that the potential safety hazard area is not within the current image data range, and the evaluation and analysis unit will handle this situation. When the potential safety hazard area is not within the current image data range, the evaluation and analysis unit will correct the real-time mine terrain spatial basic image data to be evaluated. Correction includes expanding the coverage of image data, adjusting the parameters or attributes of image data, etc., to ensure that the potential safety hazard area can be accurately included in the evaluation range. Through image data correction, the evaluation and analysis unit can improve the comprehensiveness and accuracy of the evaluation.

[0078] After completing the image data correction, the evaluation and analysis unit will retrieve the real-time natural environment data of the mine's coordinate location from the database. The data includes natural factors that affect the safety of underground space in mines, such as temperature, humidity, rainfall, earthquakes, and floods.

[0079] Subsequently, the evaluation and analysis unit integrates the natural environment data with the corrected real-time spatial basic image data of the mine terrain to be evaluated. The integrated data will serve as the input of the evaluation model.

[0080] The evaluation and analysis unit uses a preset mine underground space evaluation model to evaluate the integrated data. The evaluation model is based on professional knowledge and historical data, and can analyze the relationship between data, calculate evaluation indicators, and generate comprehensive evaluation results.

[0081] The evaluation and analysis unit outputs the final evaluation results in the form of evaluation reports, charts, data visualization, etc. The results not only reflect the safety status of the underground space of the mine, but also provide important decision-making support for the safe production and management of the mine.

[0108] The data acquisition unit first collects the basic data of the underground space of the mine, such as mine coordinate information, mine construction information, mine production information, geological structure, rock properties, and groundwater conditions. The basic data is substituted into the preset digital twin model to generate basic image data of the mine terrain space. This digital twin model can simulate and reflect the actual situation of the underground space of the mine, providing a basis for subsequent evaluation and analysis.

[0109] The data acquisition unit collects the natural environment data of the mine coordinate location, such as weather information and natural disaster information, based on the mine coordinate information, and receives real-time construction information and production information of the mine underground space. The image modification unit substitutes the real-time information into the digital twin model and updates the basic image data of the mine underground space to reflect the latest construction and production conditions of the mine underground space.

[0110] The image acquisition unit continuously monitors the changes in the mine's natural environment data and the mine's underground space basic data. When the data exceeds the preset safety value, the data that exceeds the standard is substituted into the updated mine terrain space basic image data to generate real-time mine terrain space basic image data to be evaluated. The evaluation and analysis unit configures the coordinate points of the real-time mine terrain space basic image data to be evaluated, and receives the coordinates of the mine construction and production safety hazard areas for matching. If the match is unsuccessful, the image data is corrected, and the natural environment data of the real-time mine coordinate position is integrated, and a comprehensive evaluation is performed through the preset mine underground space evaluation model.

[0111] The evaluation and analysis unit analyzes the relationship between data, calculates evaluation indicators, and generates evaluation results based on the input data and set parameters. The results include evaluation reports, charts, and data visualization, which provide a scientific basis for the safety assessment of underground space in mines.

[0112] Through this series of steps, the present invention can accurately reflect the changes in geological conditions in the underground space of the mine in real time, and can still conduct effective assessment and analysis when encountering complex geological conditions such as faults, folds, karst, groundwater, etc. This not only improves the accuracy and efficiency of the assessment, but also makes the assessment results more comprehensive and objective, providing a strong guarantee for the safe production of the mine.

[0113] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if the modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include the modifications and variations, and the above-described embodiments of the present invention do not constitute a limitation on the scope of protection of the present invention.
