| To facilitate the integrated development and utilization of mine underground space, this paper reviews the current status of such practices domestically and internationally. Taking the Jurong copper mine in Jiangsu Province as a case study, five types of underground spaces were identified via 3D laser scanning, namely mined out areas (stopes), transport ramps, horizontal drifts, underground chambers, and ventilation shafts. The total volume of the surveyed underground space was approximately 1.202 million cubic meters. A comprehensive evaluation was conducted, considering factors such as spatial resource volume, ore body characteristics, hydrogeological and environmental geological conditions, stability, and economic viability. The mined out areas were deemed unsuitable for direct utilization due to their large spans and poor stability. The other space types, exhibiting good stability and regular spatial distribution, were found to be suitable for development, with an available volume of approximately 1.082 million cubic meters. Considering the distribution characteristics of the underground space, potential utilization schemes are proposed, including the construction of a semi underground pumped storage power station, a compressed air energy storage facility, underground oil storage reservoirs, underground warehouses, and facilities for science education and tourism. |
