Abstract: The mineral reserves estimation system which can support polymetal is the basis of high-efficiency estimation and dynamic management of mineral reserves. According to the characteristics of mineral reserves estimation in China, by using a traditional mineral reserves estimation method-the vertical section method as the entry point, a system realization method of mineral reserves estimation system supporting polymetal was elicited. It initially realized the traditional mineral reserves estimation subsystem supporting polymetal in digital mine software-QuantyMine, which can provide a traditional mineral reserves estimation and dynamic management platform for users, so as to enhance the efficiency and accuracy of mineral reserves estimation and management, and further promote the level of mine information work and the development of digital mine.
