Outline
A set of intelligent mining system solutions has been proposed to address the problems of numerous small and medium-sized mines, complex ore bodies, and difficult safety control in China's underground metal mining resources. Taking the complex and fragmented ore body of Tongkeng Mine as the research background, an intelligent system based on the concept of "spatio-temporal coordination" was constructed based on segmented airfield subsequent filling method. In this system, a global wireless positioning network was adopted to achieve unmanned and less-manned operations for key processes such as rock drilling, loading, and shovel transportation, as well as cross temporal and spatial collaborative scheduling of multi-equipment. Ore flow and equipment flow were innovatively integrated in depth. In the practical application of Tongkeng Mine, the system has run stably for one year, and has built three sets of standardized intelligent mining processes, one set of multi process and multi equipment collaborative support system, one complete intelligent equipment chain, and one scheduling platform. It has safely released resources in hidden danger areas, completed over 4 000 meters of perforation, and extracted 80 000 tons of ore, significantly improving operational efficiency and safety. The research results can provide a replicable technological path for intelligent mining of complex ore bodies, and provide a reference for promoting unmanned mining operations and intelligent equipment in mines.
