Description

Technical Field

[0001] This invention relates to the field of mine emergency rescue drill technology, specifically a method and system for constructing dynamic disaster scenarios and conducting virtual simulation emergency drills for mine flooding. Background Technology

[0002] Coal mine water inrush occurs within the mining space when adjacent coal and rock strata contain old aquifers, high-pressure aquifers, underground rivers, and karst caves. If water is not detected and drained in time, large amounts of mine water can flood the mining space through water-bearing fissures, inundating roadways and destroying equipment. Sometimes, water inrush accidents also involve toxic or harmful gases. The occurrence of water inrush accidents is closely related to factors such as aquifer location, fault distribution, mining pressure, and abandoned mines. The causes are complex and therefore difficult to detect and control. It is necessary to conduct advance drilling for water hazards before mining and tunneling, and to carry out timely water detection and waterproofing work.

[0003] Once a mine flooding accident occurs, the mine water rushes into the mining space and flows down the roadway from higher to lower levels, rapidly accumulating in the lower parts of the roadway and flooding it. In addition, some old mine water is acidic and contains toxic and harmful gases, which can easily poison people, cause explosions of toxic and harmful gases, collapses and other secondary disasters. Emergency rescue work can only be carried out by professional mine rescue teams with special rescue equipment to conduct initial personnel search and rescue, drainage, leak plugging and ventilation and other disaster treatment work.

[0004] Currently, the main method of training for mine flooding is classroom instruction by qualified personnel, followed by an assessment. However, the effectiveness of classroom instruction is not ideal. Escape training for frontline mine workers involves one to two emergency escape drills conducted annually. Mine rescue teams conduct flood drills by deploying water-bearing devices inside simulated tunnels to simulate minor water inrush accidents. However, mine flooding accidents involve large volumes of water, rapid flow, wide impact areas, and difficulties in pumping out and sealing off the affected areas, making them difficult to simulate in a real-world environment.

[0005] Large-scale mine flood drills cannot realistically simulate the extreme environment of a flood. Therefore, it is necessary to rely on computer virtual simulation technology to build mine flood scenarios and use PC and VR technologies to enable personnel to interact with the virtual disaster scenario. Current virtual scenarios imitate the modeling approach of games. After the model is completed once, the entire process of the disaster's development and spread is pre-set. The changes in the destructive scene after the disaster occurs are fixed and unchanging, and people can only experience a fixed process of disaster development.

[0006] Currently, most virtual simulation technologies utilize numerical simulation algorithms for flood disasters and virtual reality technology. By leveraging flood node data from small-scale mining areas obtained through numerical simulation of mine flood disasters, virtual emergency drill scenarios and disaster development processes for mine floods are constructed. Generally, the prerequisite for using high-precision numerical simulation technology is to construct a mine model based on the actual conditions of the mine. After the model is built, numerical simulation software is used to calculate the flood expansion and spread process, collecting data such as water flow velocity, water inrush location, and node elevation. Then, virtual reality technology is used to realize the development and spread of the flood within the mine. After the mine flood disaster scenario is completed, VR technology is used to train personnel for disaster avoidance and escape or emergency rescue and search operations.

[0007] There are still some problems with the existing technology, as follows:

[0008] (1) The virtual simulation of mine flood accidents uses high-precision numerical simulation technology to simulate the real flood spread scenario. In reality, due to factors such as the layout, shape, size, support method, and variety and complex layout of production equipment inside the underground roadways, the computational pressure required to simulate real underground floods is relatively large. It can only be calculated on supercomputers. If it is calculated on ordinary high-performance computers, the model size and model complexity can only be limited, resulting in the model only involving a few key roadways in the flood spread. The virtual training area can only be limited to a small range.

[0009] (2) Data such as the spread and diffusion of underground water disasters and the flow velocity of water inrush can be obtained through numerical simulation. However, actual mine water disasters can close roadways and disrupt the mine ventilation balance. In addition, the mine water in the water disaster will release toxic and harmful gases. When the ventilation airflow balance is disrupted, it is even more difficult to simulate parameters such as the spread and diffusion of toxic and harmful gases under the influence of airflow under different water level conditions.

[0010] (3) The creation of complex mine models required for numerical simulation requires professional 3D modeling software. After the model is successfully created, it can only be used to carry out simulation exercises for mining space in a certain time and space state. The actual mining face is constantly advancing and changing, making it difficult to track and simulate mining space in different mining states.

[0011] (4) It is difficult to simulate the distribution of water flow and the speed of water spread at the intersection of multiple roadways with different elevations using numerical simulation methods. The actual spread of water disasters in mines is closely related to the roadway elevation, the size and layout of water ditches and the facilities and equipment in the roadways. Different roadways have different water spread situations due to factors such as support methods, equipment in the roadways, waterproof doors and windows, and water tank layout. It is necessary to refer to the actual hydrological data underground.

[0012] Most of these technologies discuss emergency evacuation methods for coal mine flooding disasters, and then use simulations to optimize personnel evacuation routes in emergency evacuation of coal mine flooding accidents, without discussing the spread of flooding. For mine rescue personnel, although most rescue teams have set up simulated tunnels and regularly conduct rescue drills, these drills mainly target general mine water inrushes with small water volumes and simple pumping operations, which are quite different from the complex flooding rescue environment in actual mines and are difficult to achieve the purpose of flooding disaster rescue training.

[0013] In response to the current development of fixed disaster processes in virtual simulation of mine floods, which cannot simulate the development and spread of real mine fires or realize the impact of dynamic measures such as mine drainage and closure on floods, there is an urgent need for a method and system for constructing dynamic disaster scenarios and conducting virtual simulation emergency drills for mine floods. This system should be able to quickly build high-precision 3D models of mines and dynamically change the disaster scenario of flood accidents based on the sudden occurrence of disasters and the operational feedback of trainees, thereby improving the realism of the simulation and the training effect of the trainees. Summary of the Invention

[0014] One of the objectives of this invention is to provide a method for constructing dynamic disaster scenarios and conducting virtual simulation emergency drills for mine flooding. This method can quickly construct high-precision 3D models of mines and dynamically change the disaster scenarios of flooding accidents based on the sudden occurrence of disasters and the operational feedback of trainees, thereby improving the realism of the simulation and the training effect of the trainees.

[0015] The basic solution provided by this invention is a method for constructing dynamic disaster scenarios and conducting virtual simulation emergency drills for mine flooding, comprising the following:

[0016] S1. Obtain the data parameters of the mine and construct a data parameter database;

[0017] S2. Construct a model library based on the equipment data dimensions from the obtained mine data parameters;

[0018] S3. Obtain the configuration file and build the configuration file database;

[0019] S4, the task of editing the dynamic disaster scenario construction for mine flooding;

[0020] S5. Based on the task, retrieve the corresponding models and configuration files from the model library and configuration file database to construct a high-precision 3D model of the mine.

[0021] S6. Based on the high-precision 3D model of the mine, generate a flood disaster model to simulate the occurrence, expansion and spread of flood disasters in different mining spaces, assess the impact range of flood disasters, and obtain information on the spread progress.

[0022] S7. Based on the spread progress information, determine the spread of the flood accident in the high-precision 3D mine model, and use a high-precision scene rendering algorithm to analyze the rendering range and generate rendering information.

[0023] S8. Based on the rendering data, render and display the simulated flood scene destruction process after rendering;

[0024] S9. Using VR, AR, and MR technologies, obtain information on the impact of trainees' collaborative operation on a high-precision 3D mine model on the scene;

[0025] S10. Based on the impact information, simulate the spread of the flood disaster, obtain the spread progress information, and execute S7.

[0026] S11. Set up information on sudden disaster situations during the drill;

[0027] S12. Based on the information on the sudden disaster, simulate the spread of the corresponding flood accident, obtain the spread progress information, and execute S7.

[0028] S13. Obtain evaluation information on trainees, generate a report based on the evaluation information, and output the report.

[0029] Furthermore, the data parameters include: basic topographic data, mine shaft and tunnel data, mine geological data, and mine survey data, which are used to construct a basic topographic database, a mine shaft and tunnel database, a mine geological database, and a mine survey database, respectively.

[0030] Furthermore, the model library includes static models and dynamic models.

[0031] Furthermore, it also includes: S14, setting ventilation parameter information during the exercise;

[0032] S15. Based on the ventilation parameter information, simulate the spread of the flood disaster, obtain the spread progress information, and execute S7.

[0033] The beneficial effects of this solution are: This solution first constructs a data parameter database, a model library, and a configuration file database to pre-store information for easy subsequent retrieval;

[0034] Then, users can edit the task of building a dynamic disaster scenario of mine flooding according to the exercise requirements. Based on the task, the corresponding model and configuration file are retrieved from the model library and configuration file database to build a high-precision 3D mine model, which improves the construction speed and enables the rapid and complete construction of a high-precision 3D mine model. Then, based on the high-precision 3D mine model, a flood model is generated to simulate the occurrence, expansion and spread of flood accidents in different mining spaces, assess the impact range of flood accidents, and obtain information on the spread progress.

[0035] After obtaining the spread progress information, the spread of the flood accident in the high-precision 3D mine model is determined based on the spread progress information. A high-precision scene rendering algorithm is then used to analyze the rendering range and generate rendering information. Based on the rendering information, the scene destruction process of the flood simulation is displayed, thereby completing the simulation of the flood accident in the mine.

[0036] Specifically, this solution utilizes VR, AR, and MR technologies to acquire information on the impact of trainees' collaborative operations on a high-precision 3D mine model. Simultaneously, before or during drills, information on sudden disaster events can be set. Based on this impact or event information, the simulation of a flood's spread is generated, and its progress is recorded. Based on this progress information, corresponding rendering information is generated for further rendering, ensuring the simulated environment provides feedback consistent with actual disaster scenarios. This allows for dynamic changes in the flood disaster scenario based on sudden events and trainee feedback, improving the realism of the simulation and the training effectiveness. Furthermore, during and after drills, evaluation information on trainees is acquired, and reports are generated and output based on these evaluations to assist in optimizing the drills, achieving effective emergency rescue drills and escape training.

[0038] Furthermore, it can set ventilation parameters before or during drills, and obtain information on the spread of the simulated flood based on the ventilation parameters, so as to further render the simulation. By changing the ventilation conditions of the simulated mining area (adjusting ventilation, reversing ventilation, nitrogen injection, isolation and sealing, etc.), it can simulate the response changes of the flooded area and achieve the purpose of dynamic disaster simulation of mine floods.

[0039] The second objective of this invention is to provide a dynamic disaster scenario construction and virtual simulation emergency drill system for mine flooding, which can quickly build a high-precision 3D model of the mine and dynamically change the disaster scenario of flooding accidents based on the sudden occurrence of disasters and the operational feedback of trainees, thereby improving the realism of the simulation and the training effect of the trainees.

[0052] The intelligent model control module is also used to transmit impact information to the flood accident parameter simulation module;

[0053] The flood accident parameter simulation module is also used to simulate the spread of the flood accident based on the impact information, obtain the spread progress information, and send it to the intelligent model control module, real-time rendering display module and training data centralized control module.

[0054] The intelligent drill guidance module is used to set up information on sudden disaster situations during the drill and send this information to the intelligent model control module.

[0055] The intelligent model control module is also used to transmit information about sudden disasters to the flood accident parameter simulation module;

[0056] The flood accident parameter simulation module is also used to simulate the spread of the flood accident based on the information of the sudden disaster, obtain the spread progress information, and send it to the intelligent model control module, the real-time rendering display module, and the training data centralized control module.

[0057] The intelligent exercise evaluation module is used to obtain evaluation information on trainees, generate reports based on the evaluation information, and output the reports.

[0058] The observation module is used to display the rendered flood simulation scene destruction process.

[0059] Furthermore, the data parameters include: basic topographic data, mine shaft and tunnel data, mine geological data, and mine survey data, which are used to construct a basic topographic database, a mine shaft and tunnel database, a mine geological database, and a mine survey database, respectively.

[0060] Furthermore, the model library includes static models and dynamic models.

[0061] Furthermore, the intelligent drill guidance module is also used to set ventilation parameter information during the drill and send the ventilation parameter information to the intelligent model control module;

[0062] The intelligent model control module is also used to transmit ventilation parameter information to the flood accident parameter simulation module;

[0063] The flood accident parameter simulation module is also used to simulate the spread of the flood accident based on ventilation parameter information, obtain the spread progress information, and send it to the intelligent model control module.

[0064] The beneficial effects of this solution are as follows: This solution constructs a data parameter database, a model library, and a configuration file database through a mine parameter database module, a mine model creation module, a model library module, and a configuration file library module, and pre-stores information for easy retrieval later;

The real-time rendering display module renders the scene based on the rendering information and displays the scene destruction process of the flood simulation after rendering, thereby completing the simulation of the flood accident in the mine.

[0068] In particular, this solution also includes a multi-person collaborative training module, which uses VR, AR, and MR technologies to feed back information on the impact of trainees' collaborative operations on the scenario to the intelligent model control module in real time.

[0069] Simultaneously, before or during the drill, the intelligent drill guidance module can be used to set information on sudden disaster situations during the drill. The flood accident parameter simulation module simulates the spread of the flood accident based on the impact information or sudden disaster situation information, and obtains the spread progress information. The real-time rendering and display module then generates corresponding rendering information based on the spread progress information, and proceeds to the next rendering step, so that the simulated environment provides feedback that conforms to the actual disaster environment. This enables the dynamic adjustment of the flood accident disaster scenario based on the sudden disaster situation and the operational feedback of the trainees, improving the realism of the simulation and the training effect of the trainees. Furthermore, during and after the drill, the intelligent drill evaluation module obtains evaluation information of the trainees, generates reports based on the evaluation information, and outputs reports to assist in optimizing the drill, achieving good emergency rescue drills and escape training effects.

It can simulate the dynamic evolution of floods under the influence of mine ventilation, the spread and development of floods, the simulation of toxic and harmful gases, the collapse and blockage of tunnels, the change of floods with underground ventilation conditions, and automatically render mine flood scenarios based on the simulation results.

[0071] Furthermore, the intelligent exercise guidance module can be used to set ventilation parameters before or during the exercise. Based on the ventilation parameters, the spread of the simulated flood accident can be obtained, and the spread progress information can be obtained for further rendering. By changing the ventilation conditions of the simulated mining area (adjusting the airflow, reversing the airflow, nitrogen injection, isolation and sealing, etc.), the simulated response changes of the flooded area can be realized, thus achieving the purpose of dynamic disaster simulation of mine floods.

Sudden disaster situations include randomly setting the location, size, and number of water inrush points, as well as the location and severity of roadway collapses. The flood accident parameter simulation module initializes pre-disaster values ​​and renders the initial disaster environment. Rescue personnel among the trainees then stand by at multiple virtual underground bases. Following procedures, they carry out disaster response work, completing a full rescue process including pre-disaster reconnaissance, personnel search and rescue, drainage and ventilation, on-site marking, disaster response, and disaster area recovery. Escape participants can collaboratively conduct self-rescue and escape drills after a sudden flood, verifying the scientific validity of the mine flood emergency plan.

[0112] The intelligent model control module is also used to transmit information about sudden disasters to the flood accident parameter simulation module;

[0113] The flood accident parameter simulation module is also used to simulate the spread of the flood accident based on the information of the sudden disaster, obtain the spread progress information, and send it to the intelligent model control module, the real-time rendering and display module and the training data centralized control module. The real-time rendering and display module transmits the rendered scene to the intelligent exercise evaluation module, the observation terminal module and the multi-person collaborative exercise module.

[0114] The intelligent drill evaluation module is used to acquire evaluation information of trainees, generate reports based on the evaluation information, and output the reports. Specifically, the intelligent drill evaluation module comprehensively scores the key tasks of the trainees' disaster response process, and automatically generates rescue reports or escape reports in text and image formats to evaluate and analyze the rescue or escape effectiveness, facilitating subsequent teams and trainees to improve emergency rescue efficiency. In this embodiment, the intelligent drill evaluation module includes: an expert drill evaluation module, a referee evaluation module, and an audio and video recording and storage module. The expert drill evaluation module and the referee evaluation module are used to acquire evaluation information of experts and referees on the trainees, generate reports based on the evaluation information, and output them. The audio and video recording and storage module is used to acquire audio and video recording information, record audio and video, and store them.

[0115] The observation module is used to display the rendered flood simulation scene destruction process.

[0116] In other embodiments, the intelligent drill guidance module is also used to set ventilation parameter information during the drill and send the ventilation parameter information to the intelligent model control module; wherein setting the ventilation parameter information during the drill can be done by directly inputting the ventilation parameter information in real time. By changing the ventilation conditions of the simulated mining area (adjusting the airflow, reversing the airflow, nitrogen injection, isolation and sealing, etc.), the ventilation calculation control module built into the flood disaster parameter simulation module can transmit the blockage of roadways and the damage to ventilation structures near the flood disaster area to the flood disaster parameter simulation module in real time, so as to realize the simulated response change of the flood disaster area and achieve the purpose of dynamic disaster simulation of mine flood disaster;

[0117] The intelligent model control module is also used to transmit ventilation parameter information to the flood accident parameter simulation module;

[0118] The flood accident parameter simulation module is also used to simulate the spread of the flood accident based on ventilation parameter information, obtain the spread progress information, and send it to the intelligent model control module.
