Description

Technical Field

[0001] The embodiments of the present invention relate to the field of geographic surveying and mapping technology, and in particular to a three-dimensional geographic data monitoring system for a mine. Background Art

[0002] In recent years, with the introduction of the national green development strategy and the introduction of the "National Industry Standard for Green Mine Construction", the construction of green mines has been used as a starting point to optimize the layout structure of mineral resource development and improve the efficiency of mineral resource utilization, which has become the focus of mineral resource management. In addition, the "Notice on Strengthening and Improving Mineral Law Enforcement" issued by the Ministry of Natural Resources pointed out that there are currently some illegal mining problems in local areas, including: unlicensed mining, cross-border mining, and illegal mining in the name of restoration and management. To this end, the natural resources department has issued relevant documents many times, requiring the improvement of the supervision effect of protective development and utilization of open-pit mines and environmental governance. Comprehensive monitoring and management of mineral resource development and utilization has also become a top priority.

[0003] The construction of real-life 3D China is accelerating, but in the field of mineral resource supervision, there is still a lack of widespread application of 3D modeling and visualization of mines. At present, the domestic mining area monitoring method based on satellite images is widely used, but there are problems such as low data source accuracy, single monitoring means and inability to provide intuitive 3D information, which makes it difficult to comprehensively monitor and manage mineral resources. Existing technical solutions face the following problems:

[0004] (1) The existing technical solutions use two-dimensional satellite remote sensing images. The data source accuracy is not high. It can only obtain the scope of the mining area and it is difficult to extract the height and depth information of the mine. The monitoring method is single and the display effect is not intuitive.

[0005] (2) Existing technical solutions make it difficult to achieve unified and efficient management of data from different sources and types, increasing the risk of duplicate or missed information collection. The integrity and accuracy of the data are difficult to guarantee, and the potential for efficient application of data is also limited.

[0006] (3) The existing technical solutions require staff to go to the mining area to conduct field measurements, conduct statistical analysis on the measurement data, and write analysis reports. The amount of mine monitoring data is huge, and most of the data analysis work needs to be completed by professional technicians, which is inefficient and difficult to scale up.

[0007] (4) The existing technical solutions lack all-round real-time monitoring of mines and are unable to obtain comprehensive real-time data in a timely manner, making it difficult for staff to conduct professional data management and scientific decision-making. The timeliness of data needs to be improved.

[0008] (5) Existing technical solutions mainly use numbers and text to record mine monitoring data. Complex data lacks intuitive comparison, making the meaning and trend of the data unclear. The data cannot be fully mined and analyzed, making it difficult to realize its due value.

[0009] The existing technical solutions do not take into account that when a computer opens multiple large satellite images and three-dimensional model files, a low-configuration computer will greatly affect the speed of data opening, seriously reducing the efficiency of the operation. Summary of the invention

[0010] The embodiment of the present invention provides a three-dimensional geographic data monitoring system for a mine, which solves the technical problem that the existing technical solutions lack all-round real-time monitoring of the mine and cannot obtain comprehensive real-time data in a timely manner.

[0011] The embodiment of the present invention provides a three-dimensional geographic data monitoring system for a mine, comprising:

[0012] Analysis and reporting module, which is used to realize automatic data analysis and report generation; the module integrates field work auxiliary tools including digital elevation model loading, profile analysis, point selection measurement and cut-fill comparison;

[0013] The supervision platform module accesses multi-source data to provide users with real-time monitoring functions, supports the delineation of suspected cross-border mining areas, the addition of supervision issues and violation warnings, and can perform area, distance measurement and triangulation analysis on violation problem areas;

[0014] The statistical chart module realizes the visualization and interaction of data by operating digital orthophoto elements and chart libraries, and displays key information such as resource distribution of mining areas, expiration of mining rights, mining progress, and filling and excavation statistics in the form of charts, thus realizing data visualization.

[0015] Furthermore, the system introduces an oblique photography model to present the mining area in a true three-dimensional form and provide rich three-dimensional information on key indicators such as mining volume, reserves and change areas.

[0016] Furthermore, the system integrates different types of data sources, including digital elevation models, orthophotos, Tiandi map images, and oblique three-dimensional models, to achieve multi-source comparison and analysis of mining area data.

[0017] Furthermore, the system applies Cesium JS technology to realize the function of efficiently displaying three-dimensional geographic data in a web browser.

[0018] Furthermore, the system establishes an authorization mechanism, and only computers with authorization files can operate the system normally, which can limit unauthorized access.

[0019] The technical solution of the embodiment of the present invention enables mine managers to better and faster understand the mine situation by setting up an analysis report module, a supervision platform module and a statistical chart module, and can promptly discover abnormal situations and take corresponding measures.

Figure 1 The three-dimensional geographic data monitoring system 100 of a mine according to an embodiment of the present invention specifically includes:

[0025] An analysis and reporting module 110 is used to realize automated data analysis and report generation; the module integrates field work auxiliary tools including digital elevation model loading, profile analysis, point selection measurement, and cut-fill comparison;

[0036] Specifically, in the user management interface of this system, the administrator can set the permissions and roles of different users to ensure system security and reasonable access to data. The system adopts special mechanisms to ensure the security of data and systems. The system establishes an authorization mechanism, and only computers with authorization files can run this system normally, which can limit unauthorized access. The encapsulation of the core code and the permission mechanism also help to protect the security of the system.

[0037] The present invention integrates image information from different data sources and can perform comprehensive comparative analysis, providing a richer perspective and decision-making basis for mine management.
