Description

Technical Field

[0001] The present invention relates to the technical field of model supervision, and particularly relates to a tailings pond dam-break simulation system and method. Background Art

[0002] A tailings pond is a storage site for waste containing ore residues, ore powders, and chemical substances generated during the mining process. They are usually large artificial structures built to store the solid waste remaining after ore processing, such as slag, coal gangue, tailings, etc. Tailings ponds are usually enclosed by building dams or retaining walls to form a closed storage space. Although they can temporarily store solid waste, they may have negative impacts on the surrounding environment, such as water pollution, soil pollution, etc. Therefore, strict environmental management and monitoring measures are required. Once the structure of the tailings pond is damaged or collapses, the stored tailings and sewage may suddenly leak out. Such an event may have serious impacts on the surrounding environment, residents, and ecosystem, and even cause catastrophic consequences.

[0067] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0068] Embodiment 1

[0069] This embodiment provides a tailings dam break simulation system, as Figure 1 shown, including:

[0070] A collection and processing module, configured to collect real-shot images of the tailings reservoir, identify the basic information corresponding to each solid waste in the real-shot images, and establish the actual situation information of the tailings reservoir;

[0071] A model establishment module, configured to analyze the pressure information of different solid wastes on the tailings reservoir according to the actual situation information, and establish a three-dimensional pressure simulation model of the tailings reservoir in combination with the structural information of the tailings reservoir;

[0072] A pressure analysis module, configured to run the three-dimensional pressure simulation model to obtain the pressure threshold corresponding to each dam structure in the tailings reservoir;

[0073] A state construction module, configured to construct the dam break positions corresponding to different preset breach states of the tailings reservoir according to the preset breach states in combination with the pressure threshold corresponding to each dam structure;

[0074] The dam-break analysis module is used to monitor each dam-break position in the three-dimensional pressure simulation model, obtain the dam-break moment corresponding to each corresponding dam-break position, establish a waste treatment plan for the tailings pond and display it.

[0075] In this example, the basic information includes the appearance and density of solid waste;

[0076] In this example, the actual situation information represents the accumulation of various solid wastes in the tailings pond;

[0077] In this example, the pressure threshold represents the maximum pressure that the dam structure can withstand;

[0078] In this example, the preset breach state represents different types of breaches, including: insufficient foundation bearing capacity, dam body collapse, uneven filling, insufficient compaction degree, drainage failure, excessive tailings accumulation, illegal mining activities, etc.

[0079] In this example, one preset breach state can correspond to one or more dam-break positions;

[0080] In this example, the dam-break moment represents the moment corresponding to the occurrence of the dam-break at the first dam-break position.

[0081] The working principle and beneficial effects of the above technical solution: In order to effectively prevent the dam-break of the tailings pond and avoid casualties, environmental pollution and economic losses, first, the solid waste in the tailings pond is identified according to the actual shot image of the tailings pond, so as to establish the actual situation information of the tailings pond. Then, according to the actual situation information, the pressure information of different solid wastes on the tailings pond is analyzed, and combined with the structural information of the tailings pond, a three-dimensional pressure simulation model is established. By running this model, the pressure threshold corresponding to each dam structure in the tailings pond is determined, and the dam-break positions corresponding to each dam structure under different preset breach states are analyzed. Further, according to the actual situation of the tailings pond, the dam-break is supervised by using the three-dimensional pressure simulation model, and the dam-break moment of the tailings pond is estimated. Finally, a plan for treating waste is established within this moment, so that waste treatment can be carried out within an effective time, maximizing the integrity of the tailings pond, reducing the risk of dam-break of the tailings pond, and protecting human life and property safety and the ecological environment.

[0082] Embodiment 2

[0083] On the basis of Embodiment 1, for the tailings pond dam-break simulation system, the acquisition and processing module includes:

[0084] The image acquisition unit is used to acquire the regional image corresponding to each reservoir area of the tailings pond, and combine the regional images to obtain the actual shot image of the tailings pond;

[0085] An image processing unit, which is configured to perform an overflow process on the real-shot image when there are threshold pixel values outside a preset pixel value range in the real-shot image, obtain overflow pixel points corresponding to each of the threshold pixel values, perform a truncation process on each of the overflow pixel points respectively, and generate a valid grayscale image of the tailings pond;

[0086] A contour separation unit, which is configured to perform a rough recognition on the valid grayscale image, obtain a plurality of object contours included in the valid grayscale image, enhance a plurality of pixel points corresponding to each of the object contours respectively, and obtain a plurality of solid waste contours included in the valid grayscale image;

[0087] A live analysis unit, which is configured to find the texture characteristics corresponding to each of the solid waste contours in the valid grayscale image, establish basic information of the corresponding solid waste, establish a position matrix according to the image positions of each of the solid wastes in the valid grayscale image, and input the basic information into the position matrix to obtain the live information of the tailings pond.

[0088] In this example, each reservoir area corresponds to an area image, and the reservoir area is a part of the tailings pond;

[0089] In this example, the preset pixel value range is 0 - 255;

[0090] In this example, the overflow process represents a process of truncating the pixels exceeding 0 - 255 in the real-shot image. The purpose of performing the overflow process is that during the processing, pixel values exceeding this range may be generated, and appropriate processing is required to avoid loss of image quality or unexpected results;

[0091] In this example, the truncation quantity means directly truncating the pixel values exceeding the range to the maximum or minimum allowed values. For example, truncating the pixel values exceeding the range of 0 to 255 to 0 or 255;

[0092] In this example, the rough recognition represents a process of extracting contour lines in the valid grayscale image;

[0093] In this example, the function of performing pixel point enhancement is to separate the object contour from the image;

[0094] In this example, the position matrix represents a matrix established based on the distribution positions of each solid waste in the tailings pond as matrix positions.

[0095] Working principle and beneficial effects of the above technical solution: To further analyze the distribution of solid waste in the tailings pond, first, when collecting real-shot images, multiple regional images were used for stitching to obtain a real-shot image. Then, the overflow pixel points in the real-shot image were truncated to obtain an effective grayscale image. Further, rough recognition and pixel point enhancement were performed on the effective grayscale image to obtain several solid waste contours contained in the effective grayscale image. Then, the basic information of the solid waste was established by combining the texture features of each solid waste contour. Finally, the actual situation information of the tailings pond was established in the form of a matrix. In this way, multiple contours can be analyzed simultaneously to establish the overall actual situation information, improving the credibility of the actual situation information and ensuring the timeliness of the actual situation information.

[0096] Example 3

[0097] Based on Example 1, for the tailings pond dam-break simulation system, the model establishment module includes:

[0098] A solid analysis unit, configured to determine the volume of the corresponding solid waste according to the basic information, combine the basic density corresponding to each solid waste to determine the weight information corresponding to each solid waste, and establish the solid waste stack height characteristics corresponding to each reservoir area in the tailings pond according to the actual situation information;

[0099] A pressure analysis unit, configured to determine the bearing pressure corresponding to each reservoir area based on the solid waste stack height characteristics in combination with the weight information corresponding to each solid waste, trace the bearing pressure corresponding to each reservoir area respectively, and obtain the pressure value of each solid waste on the tailings pond;

[0100] A model preparation unit, configured to establish a model framework according to the structural information of the tailings pond, mark the pressure value of each solid waste on the tailings pond in the model framework respectively to obtain the bearing pressure value corresponding to each dam body structure, and simultaneously establish a three-dimensional initial model according to the model framework and the real-shot image;

[0101] A model establishment unit, configured to establish a conceptual virtual waste corresponding to each solid waste according to the actual situation information, establish a virtual pressure of each conceptual virtual waste based on the pressure value of each solid waste on the tailings pond, map each conceptual virtual waste to the three-dimensional initial model respectively based on the solid waste stack height characteristics, and judge whether the mapping position is correct according to the virtual bearing pressure value corresponding to each model dam body structure in the three-dimensional initial model to obtain the three-dimensional pressure simulation model of the tailings pond.

[0102] In this example, the solid waste stack height characteristic refers to the height characteristic presented when the solid waste is piled up;

[0103] In this example, pressure traceability means decomposing the applied pressure to determine the solid waste corresponding to each decomposed force.

[0104] The working principle and beneficial effects of the above technical solution: To build an available model, the weight information of the solid waste was determined based on the basic information and basic density. Then, the solid waste stack height characteristics of each reservoir area in the tailings pond were determined using the live information, thereby determining the pressure borne by each reservoir area. By tracing the applied pressure, the pressure value of the solid waste on the tailings pond was determined. At the same time, the structural information was used to establish the model framework, and the pressure value borne by each dam structure was determined through pressure value marking. A three-dimensional initial model was established simultaneously. Subsequently, a three-dimensional pressure simulation model of the tailings pond was established by mapping the conceptual virtual waste corresponding to each solid waste to the three-dimensional initial model. The three-dimensional pressure simulation model established in this way not only presents every detail in the tailings pond but can also be updated in real time according to the live image, ensuring the fit between the model and the actual situation.

[0105] Example 4

[0106] Based on Example 3, for the tailings pond dam-break simulation system, the model establishment unit includes:

[0108] The object mapping subunit is used to establish the virtual pressure corresponding to each conceptual virtual waste according to the pressure value of each solid waste on the tailings pond, determine the stack height order corresponding to each conceptual virtual waste according to the solid waste stack height characteristics, and map each conceptual virtual waste into the three-dimensional initial model according to the push height order;

[0109] The mapping inspection subunit is used to divide the tailings pond into several dam structures based on the structural information to obtain several model dam structures included in the three-dimensional initial model, statistically calculate the virtual bearing pressure values corresponding to each model dam structure based on the virtual pressure corresponding to each conceptual virtual waste, and when the virtual bearing pressure value of the model dam structure is inconsistent with the bearing pressure value of the corresponding dam structure, determine that an error has occurred in the mapping work;

[0110] An error adjustment subunit is used to perform an overall analysis on the completed mapped three-dimensional initial model to obtain several model positions where errors occur, and re-project the target concept virtual wastes corresponding to different model positions until the virtual bearing pressure value of each model dam structure is consistent with the bearing pressure value of the corresponding dam structure, thereby generating a three-dimensional pressure simulation model of the tailings pond.

[0111] In this example, each concept virtual waste corresponds to a virtual pressure.

[0112] The working principle and beneficial effects of the above technical solution: To further ensure the effectiveness and authenticity of the model, count the current solid waste quantity in the tailings pond according to the actual situation information, then determine multiple waste description information contained in the actual situation information by means of information separation, thereby establishing corresponding concept virtual wastes, determine whether concept construction has been carried out for each solid waste by comparing the data difference between the constructed data and the current solid waste data, then establish virtual pressures according to the pressure values of each solid waste, and at the same time determine the stacking height order of the concept virtual wastes according to the stacking height characteristics of the solid wastes, and then perform stacking in the three-dimensional initial model in sequence. During the stacking process, analyze the virtual bearing pressure values of each model dam structure. When the pressure value is inconsistent with the bearing pressure value, re-project, and finally generate a three-dimensional pressure simulation model. During the model establishment period, the data is calibrated multiple times to avoid data loss. When performing mapping, the means of sequential mapping is adopted, effectively avoiding the problem of unclear pressure values caused by overall mapping.

[0116] A dam analysis unit is used to establish the pressure correlation relationship between different dam structures according to the structure information, and establish the associated pressure value of each dam structure in combination with the current pressure value;

[0117] A pressure correction unit is used to correct the current pressure value based on the associated pressure value to obtain the actual pressure value corresponding to each dam structure;

[0118] A threshold determination unit is used to adjust the bearable pressure threshold of the corresponding dam structure according to the ratio between the actual pressure value and the current pressure value, and obtain the bearing pressure threshold corresponding to each dam structure.

[0119] In this example, the associated pressure value refers to the pressure value that appears on other dam structures when a pressure is applied to one dam structure due to the connection relationship between different dam structures.

[0120] The working principle and beneficial effects of the above technical solution: In order to monitor the overall tailings pond, first calculate the current pressure value and the tolerable pressure value of each dam structure according to the three-dimensional pressure simulation model, analyze the associated pressure values between different dam structures in combination with the structural information, thereby determining the ratio between the actual pressure value and the current pressure value of the dam structure, and use this ratio to adjust the pressure tolerance threshold of the dam structure, achieving synchronous adjustment and obtaining the accurate pressure tolerance threshold of each dam structure.

[0144] Step 5: Supervise each dam-break position in the three-dimensional pressure simulation model to obtain the dam-break moment corresponding to each dam-break position, establish a waste treatment plan for the tailings pond and display it.

[0145] In this example, the basic information includes the appearance and density of solid waste;

[0146] In this example, the actual situation information represents the accumulation of various solid wastes in the tailings pond;

[0147] In this example, the pressure threshold represents the maximum pressure that the dam structure can withstand;

[0148] In this example, the preset breach state represents different types of breaches, including: insufficient foundation bearing capacity, dam body collapse, uneven filling, insufficient compaction degree, drainage failure, excessive tailings accumulation, illegal mining activities, etc.

[0149] In this example, one preset breach state can correspond to one or more dam-break positions;

[0150] In this example, the dam-break moment represents the moment corresponding to the occurrence of the first dam-break position.

[0151] Working principle and beneficial effects of the above technical solution: In order to effectively prevent the dam break of a tailings pond, avoid casualties, environmental pollution and economic losses, first, solid waste in the tailings pond is identified based on the actual photographed images of the tailings pond, so as to establish the actual situation information of the tailings pond. Then, according to the actual situation information, the pressure information of different solid wastes on the tailings pond is analyzed, and a three-dimensional pressure simulation model is established in combination with the structural information of the tailings pond. By running this model, the pressure threshold corresponding to each dam structure in the tailings pond is determined, and the dam break position corresponding to each dam structure under different preset breach states is analyzed. Further, according to the actual situation of the tailings pond, the three-dimensional pressure simulation model is used for dam break supervision to estimate the dam break time of the tailings pond. Finally, a waste treatment plan is established within this time, so that waste can be treated within an effective time, ensuring the integrity of the tailings pond to the greatest extent, reducing the risk of dam break of the tailings pond, and protecting human life and property safety and the ecological environment.

[0152] Example 10

[0153] Based on Example 9, for the tailings pond dam break simulation system, Step 1 includes:

[0154] Step 11: Collect the regional images corresponding to each reservoir area of the tailings pond, and combine the regional images to obtain the actual photographed image of the tailings pond;

[0155] Step 12: When there are threshold pixel values outside the preset pixel value range in the actual photographed image, perform overflow processing on the actual photographed image to obtain the overflow pixel points corresponding to each threshold pixel value, and perform truncation processing on each overflow pixel point respectively to generate the effective grayscale image of the tailings pond;

[0156] Step 13: Coarsely identify the effective grayscale image to obtain several object contours included in the effective grayscale image, and enhance the several pixel points corresponding to each object contour respectively to obtain several solid waste contours included in the effective grayscale image;

[0157] Step 14: Search for the texture characteristics corresponding to each solid waste contour in the effective grayscale image, establish the basic information of the corresponding solid waste, establish a position matrix according to the image position of each solid waste in the effective grayscale image, and input the basic information into the position matrix to obtain the actual situation information of the tailings pond.

[0158] In this example, each reservoir area corresponds to a regional image, and the reservoir area is a part of the tailings pond;

[0159] In this example, the preset pixel value range is 0 - 255;

[0160] In this example, overflow processing refers to the process of truncating the pixels in the real-shot image that exceed the range of 0 - 255. The purpose of overflow processing is that during the processing, pixel values outside this range may be generated, and appropriate processing is required to avoid loss of image quality or unpredictable results.

[0161] In this example, the truncation quantity means directly truncating the pixel values outside the range to the maximum or minimum allowed values. For example, truncating the pixel values outside the range of 0 to 255 to 0 or 255.

[0162] In this example, rough recognition refers to the process of extracting contour lines within the effective grayscale image.

[0163] In this example, the role of pixel point enhancement is to separate the object contour from the image.

[0164] In this example, the position matrix is a matrix established based on the distribution positions of each solid waste in the tailings pond as matrix positions.

[0165] The working principle and beneficial effects of the above technical solution: In order to further analyze the distribution of solid waste in the tailings pond, first, when collecting real-shot images, multiple regional images are used for splicing to obtain a real-shot image. Then, the overflow pixel points in the real-shot image are truncated to obtain an effective grayscale image. Further, rough recognition and pixel point enhancement are performed on the effective grayscale image to obtain several solid waste contours included in the effective grayscale image. Then, the basic information of the solid waste is established by combining the texture features of each solid waste contour. Finally, the actual situation information of the tailings pond is established in the form of a matrix. In this way, multiple contours can be analyzed simultaneously, the overall actual situation information can be established, the credibility of the actual situation information is improved, and the timeliness of the actual situation information is ensured.
