Description

Technical Field

[0001] The present invention belongs to the technical field of mine resource management, and in particular relates to a mine resource reserve dynamic management system based on multiple models and a construction method. Background Art

[0002] Mine resource reserve management refers to the process of comprehensive monitoring and optimization of the exploration, evaluation, mining and utilization of mineral resources. This technology is mainly used in the mining field, including various mining enterprises such as metal mines, non-metallic mines and energy minerals. The traditional mine resource reserve management system mainly relies on periodic geological exploration, manual data collection and regular reserve evaluation to guide the production planning and resource utilization of mines.

[0003] At present, existing technologies usually solve the problem of mine resource reserve management in the following ways: regular geological exploration and measurement, collection of mine production data, use of professional software for resource reserve calculation and evaluation, and generation of static reserve reports and charts. These methods mainly rely on manual operation and periodic data updates, and guide mine production decisions through regular evaluation and reporting.

[0004] However, the existing mine resource reserve management technology has the following main problems:

[0005] 1. Lack of real-time performance: Traditional methods cannot reflect the production status of mines in real time, resulting in a time lag between resource assessment and mining planning, affecting the timeliness and accuracy of decision-making;

[0006] 2. Low efficiency of manual operation: Manual data collection and processing is not only time-consuming and labor-intensive, but also prone to errors, affecting management efficiency and data quality;

[0007] 3. Lack of dynamic monitoring capabilities: The existing system lacks real-time monitoring and prediction capabilities, making it difficult for mining companies to respond to emergencies and safety risks in the production process in a timely manner;

[0008] 4. Insufficient intelligence: Traditional systems lack the support of intelligent algorithms and models, making it difficult to achieve intelligent management and optimized decision-making of geological resources;

[0009] 5. Limited visualization: Existing technologies are insufficient in 3D visualization and interaction, which is not conducive to intuitive understanding and analysis of mine resource conditions;

[0010] These problems restrict the efficient management and sustainable utilization of mining resources. Therefore, there is an urgent need for a dynamic management system for mining resource reserves that can achieve real-time, intelligent and visual management. Summary of the invention
