Abstract: The strategic metal mining is moving deeper in China. The concurrent extraction of deep mineral deposits and geothermal resources represents a strategic direction for deep metal mining. However,there exist no internationally comparable
precedents for such integrated mining-geothermal operations. The mining process presents numerous challenges,including complex
resource distribution characteristics,difficulties in controlling thermal hazards within the mining area,challenges in recovering
both mineral and geothermal resources,and difficulties in ensuring coordinated extraction. The challenges of utilising hightemperature
environments and geothermal resources in deep mines,alongside the symbiotic characteristics of geothermal and
mineral resources,are discussed. The necessity and feasibility of synergistic development between deep mineral resources and
mine geothermal energy are discussed. The concept of synergistic development of geothermal and mineral resources is proposed
in this paper. The concept of synergistic development of mine geothermal and mineral resources is articulated based on the
guiding principle of turning adversity into advantage. A technical framework for synergistic rock cooling through advance geothermal
extraction in mines has been proposed,integrating water-source heat pump technology,backfill pipe installation,leaching
mining techniques,and novel co-extraction methods utilising mine heat. The key technologies and process flows of this
model are elaborated in detail. The critical challenges and key scientific issues inherent in synergistic geothermal extraction of
deep mineral resources are thoroughly examined. The primary challenges in the theory and methodology of mine-heat synergistic
development of deep metal ore deposits have been identified. The development trajectory of mine-heat synergistic regulation
systems,from thermal hazard control to thermal energy utilisation,has been outlined. This provides the theoretical basis and
technical assurance for safely and efficiently co-extracting deep mine-heat resources in an intelligent manner. For the 15th Five-
Year Plan,research priorities in this field will focus on core challenges,including fine-scale characterization of mineral-heat resource
occurrence mechanisms in deep multi-field coupling environments,synergistic regulation of thermal energy extraction
and mining processes under high-temperature and high-stress conditions,and integration of key technologies for intelligent decision-
making and efficient operation in co-extraction systems of minerals and heat. These research findings contribute the coordinated
development of deep mineral thermal resources from a conceptual innovation to an engineering reality,providing important
support for the independent development of deep resources and energy in China.
