Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0031] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present application described here.

[0032] For the convenience of description, some nouns or terms involved in the embodiments of the present application are explained below:

[0033] GIS software (Geographic Information System software) is a tool for collecting, storing, processing, analyzing and displaying geospatial data. It can help users create maps, perform spatial analysis, view geographic data and perform geographic visualization. Common GIS software includes ArcGIS, QGIS, MapInfo, Google Earth, etc. These software are often used in urban planning, environmental protection, natural resource management, geographic research and other fields. GIS software is widely used in various industries, providing users with better data management and spatial analysis capabilities.

[0034] Goaf: The hollow areas left after the underground mineral deposits have been fully or partially mined after economic mining is completed. These underground spaces are usually caused by mining activities, and as the ore is exhausted and mining ends, these hollow areas will be left. Goafs may have certain impacts on surface and groundwater systems, and appropriate measures need to be taken to treat and manage them.

[0035] Real-time water level elevation: refers to the height of a water body measured at a certain moment relative to a specific reference point or benchmark. This height can be used to measure the depth, flow rate and water level changes of the water body, which is of great significance to the fields of hydrology, water resources management and flood control projects. By monitoring and recording the real-time water level elevation, we can timely grasp the changes in the water body, prepare countermeasures in advance, and ensure the rational use and safe management of water resources.

[0036] Water filling coefficient: refers to the ratio of water added to a container of a certain volume. It is usually used to describe the liquid level in a container or the concentration of a liquid mixture. The water filling coefficient can be calculated by the volume of the container and the volume of water added. For example, if a container has a volume of 1000 ml and 500 ml of water is added, the water filling coefficient is 500 / 1000 = 0.5.

[0037] Transparent geological overlay analysis: A geological method that allows geological layers to be transparently overlaid to analyze geological structures, tectonic activities, and geological evolution processes. Through transparent geological overlay analysis, geologists can see the relationship between different geological layers more clearly, understand the time and spatial scope of geological changes, and thus study the evolutionary history of the earth in more depth. This analysis method is commonly used in the fields of geological exploration, resource exploration, and environmental geology.

[0038] Model voxelization technology: A process of converting a 3D model into a voxel grid composed of voxels (or cubic pixels). This method represents the model as a grid composed of small cubes in space, each cube is called a voxel. By voxelizing the model, it is easier to analyze, process and edit the model, such as performing collision detection, volume calculation, shape reconstruction and other operations. Common model voxelization methods include octree, gridding and voxelization techniques.

[0039] The vertex data of the triangulated network refers to the position data of the points in the three-dimensional space, usually including the coordinate value of each point. The index data of the triangulated network refers to the index data of the triangles connecting these vertices, usually represented by the vertex sequence of the triangle. These two types of data can be combined to describe the shape and structure of the triangulated network.

[0040] Overlay analysis is a commonly used analysis method in statistics to study the impact of different factors on a phenomenon or variable. In overlay analysis, two or more factors are considered simultaneously and their effects on a specific variable are analyzed to see whether they overlap or interact with each other. Through overlay analysis, staff can determine the extent to which different factors affect the variable and whether there is an interaction between them. This analysis method can help staff better understand the relationship between variables, thereby more accurately explaining and predicting the occurrence and change of phenomena.

[0041] As introduced in the background technology, the existing technology mainly has the following shortcomings: lack of three-dimensional visualization function to display the actual spatial shape of the water body in the coal mine goaf; the volume calculation of the water body is not accurate enough, and the final result error is large when the traditional triangular cone method or other methods are used for calculation, and it cannot truly reflect the influence of the undulation of the bottom interface of the water body; the existing mine water accumulation analysis method cannot combine the online monitoring water level data to analyze the dynamic information of the water accumulation range and water accumulation volume in real time; for the water accumulation area inside the goaf that is low and lacks hydrological observation holes, the correlation and change relationship between the water level and the water accumulation area and water accumulation volume cannot be dynamically deduced. In order to solve the problem that the existing solution uses the traditional triangular cone method when conducting dynamic analysis of water accumulation in mine goafs, resulting in low accuracy in volume calculation of the water body, the embodiments of the present application provide a method, device, medium and system for determining the water accumulation volume in a mine goaf.

[0042] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0043] In this embodiment, a method for determining the amount of water accumulated in a mine goaf that runs on a mobile terminal, a computer terminal or a similar computing device is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in an order different from that shown here.

[0044] Figure 1 Flow chart of a method for determining the amount of water accumulated in a mine goaf according to an embodiment of the present application. Figure 1 As shown, the method comprises the following steps:

[0045] Step S101, obtaining a three-dimensional model of a goaf, wherein the three-dimensional model of the goaf represents a three-dimensional model of the goaf of a mine;

[0046] In one embodiment of the present application, obtaining the three-dimensional model of the goaf in the above-mentioned step S101 includes: obtaining the vertex data and index data of the goaf of the above-mentioned mine in the triangulated network; and constructing the three-dimensional model of the goaf based on the above-mentioned vertex data and the above-mentioned index data of the goaf in the triangulated network.

[0047] Collect ground data: Use ground surveying instruments such as total stations, laser scanners, etc. to conduct ground surveys around the goaf to obtain surface topographic data.

[0048] Collect underground data: Use geological exploration techniques such as drilling and seismic surveys to explore below the goaf and obtain underground geological structure data.

[0049] Data processing and integration: GIS software is used to integrate and process ground data and underground data to generate a three-dimensional model.

[0050] Specifically, the above data source is the goaf data generated by GIS software. The data saved in the file with the file format suffix Pnt is the vertex data X, Y and elevation Z of the triangulated network; the data saved in the file with the file format suffix Tri is the index data of the triangulated network; through the vertex data and index data of the triangulated network, a three-dimensional model of the goaf can be constructed.

[0051] Step S102, obtaining the real-time water level elevation of the goaf, and based on the real-time water level elevation, cutting the three-dimensional model of the goaf to obtain a three-dimensional model of the water body;

[0052] In one embodiment of the present application, the above-mentioned step S102 cuts the above-mentioned three-dimensional model of the goaf based on the above-mentioned real-time water level elevation to obtain a three-dimensional model of the accumulated water body, including: based on the above-mentioned real-time water level elevation, using model cutting technology to construct a plane at the real-time water level elevation to horizontally cut the above-mentioned three-dimensional model of the goaf to generate a two-part model; and determines that the above-mentioned three-dimensional model of the accumulated water body is the model of the part of the above-mentioned two-part model below the above-mentioned plane.

[0053] Specifically, the three-dimensional model of the water body in the goaf is constructed based on geographic coordinate data. The model cutting algorithm adopts an algorithm for finding the intersection of a plane and a model, wherein the plane data is created based on real-time water level monitoring data.

[0054] Step S103, calculating the volume of the water body based on the three-dimensional model of the water body, and calculating the amount of water accumulated in the water body based on the volume of the water body.

[0055] Through this embodiment, a three-dimensional model of the goaf can be constructed through the vertex data of the triangulated network and the index data of the triangulated network; based on the generated goaf model and the real-time water level elevation monitoring data of the goaf, a model cutting algorithm is used to construct a plane at the water level elevation, and the goaf is horizontally cut to generate a three-dimensional model of the accumulated water body; based on the constructed accumulated water body model, the volume of the accumulated water body is calculated, and finally the accumulated water volume can be obtained by multiplying the accumulated water body volume by the corresponding water filling coefficient. High-precision dynamic analysis of water accumulation in mine goafs is achieved, which solves the problem that the existing solution uses the traditional triangular cone method to calculate the volume of the accumulated water body with low accuracy when performing dynamic analysis of water accumulation in mine goafs.

[0056] In one embodiment of the present application, the step S103 of calculating the amount of water accumulated in the water body based on the volume of the water body includes: determining the amount of water accumulated in the water body as the product of the volume of the water body and a water filling coefficient.

[0057] In the specific implementation process, the above step S103 calculates the volume of the water body based on the above three-dimensional model of the water body, including: using model voxelization technology to voxelize the bounding box range of the above three-dimensional model of the water body to obtain multiple voxel blocks; judging whether each of the above voxel blocks is within the bounding box range of the above three-dimensional model of the water body; adding the volumes of all the above voxel blocks within the bounding box range of the above three-dimensional model of the water body to obtain the volume of the water body.

[0058] Specifically, the above-mentioned method for calculating the volume of the accumulated water body adopts a voxelization method. The finer the voxel division is, the more accurate the obtained accumulated water body volume data is.

[0059] The above method for calculating the range area of ​​the water body (i.e., corresponding to all voxels) is: by mapping the water body model onto a plane, the polygonal area of ​​the projection is calculated. The above method for calculating the maximum water depth of the water body is: the water surface elevation minus the minimum elevation of the goaf floor. The volume of the water body is the product of the range area of ​​the water body and the maximum water depth of the water body.

[0060] In one embodiment of the present application, after obtaining the three-dimensional model of the water body, the method further comprises: performing a transparent geological overlay analysis on the three-dimensional model of the water body to obtain an analysis result.

[0061] The new spatial relationship is intuitively displayed through the original goaf model and the dynamically generated water body model.

[0062] In one embodiment of the present application, after obtaining the analysis result, the method further includes: displaying the analysis result in a three-dimensional engine.

[0063] The three-dimensional modeling method of the present application is to produce in the form of triangulated networks, and the final result can be displayed in a mainstream three-dimensional engine. The above display is achieved through the dynamic changes of the water body model and the information interaction dialog box. From the dynamic change deduction of the water body model, it can be seen that as the water level increases (or decreases), the waterlogging boundary climbs (or falls) along the contour line of the bottom plate of the coal seam goaf, and different water depths are expressed with gradient colors. The information dialog box displays the input or access port of the water level, the custom entrance of the water filling coefficient, and the output ports of the water accumulation area, maximum depth, water accumulation volume and water accumulation amount.

[0064] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the implementation process of the method for determining the amount of water accumulation in a mine goaf of the present application will be described in detail below in conjunction with specific embodiments.
