Current status and prospects of mining technology in metal mines
Published 2025-05-01“…This gap is particularly noticeable in ultra-deep mining, where practical experience is especially lacking. (2) Future mining technologies that require urgent attention can be categorized into four types based on their criticality and urgency: bottleneck technologies, foundational technologies, urgent technologies, and forward-looking technologies. (3) The current “bottleneck” technical challenges facing China’s mining sector include the development of intelligent and unmanned technologies for open-pit mining, advanced deep mining technologies for underground operations, and the research and application of specialized mining software. (4) The urgent technologies identified in this study include precise detection and safety management technologies for goaf areas, ultra-large-scale filling mining technologies for metallic mines, and intelligent ore grade detection technologies. (5) Foundational technologies encompass rock mechanics modeling for deep mining, multi-scale fracture simulation processes under geothermal system rock–hydraulic coupling, and dynamic control theories for managing disasters associated with deep mining activities. (6) Forward-looking technologies include a range of innovations, such as new transportation technologies for deep open-pit mines, advanced deep-well lifting techniques, novel efficient rock-breaking technologies, integrated mining and beneficiation technologies, co-extraction methods for both mineral and geothermal resources, and fluidized mining techniques for metallic minerals. …”
