This paper introduces the construction target content and overall system architecture of the intelligent management and control platform as the core of the digital mine. The core concepts and design principles of the system design are discussed. The functional design of the intelligent management and control platform is listed, which mainly include functions such as intelligent ore allocation, basic information management of mines, basic information management of exploration rights, production plan management, and equipment management. The actual application of the management and control platform system in the Pinshan Limestone Mine shows that the multi-source data of the mine has been systematically integrated. The synergy of all production links has been strengthened. The production efficiency and command and dispatch efficiency of open-pit mining have been significantly improved. At the same time, it enhances the coordination and safety of mining operations, laying a technical foundation for the digital and intelligent mining of mines.
