[0002] In the existing field of mineral resource exploration and development, accurate reserve estimation is the key to mineral resource management and mining decisions. Traditional reserve estimation methods mostly rely on the superposition of two-dimensional data and manually calculate the volume and ore content of the ore body in combination with geological exploration information, resulting in incomplete data, low accuracy, and difficulty in adapting to the complex spatial distribution characteristics of the ore body. In addition, due to the lack of systematic management in the data collection and processing process, there are often problems such as data duplication, loss and delay, which not only reduces the accuracy of reserve estimation, but also prolongs the time of the entire estimation process, affecting the development efficiency of mineral resources.

[0003] The existing reserve estimation system has many deficiencies in solving complex ore body geometry and improving data accuracy. Specifically, traditional technology lacks flexible adaptability when facing different mining areas, physical properties of different ore bodies and mining difficulties, and cannot accurately handle the transmission and synchronization of multi-source data, resulting in poor data consistency. In addition, the existing system is not intelligent enough in generating mining plans, and it is difficult to provide optimized plans based on the characteristics of the ore body and mining feasibility, and lacks the ability to adjust dynamically. These technical difficulties not only limit the accuracy of reserve estimation, but also increase the cost and risk in the mining process.
