There are currently a large number of closed/abandoned mines in China, among which closed/abandoned mine underground space resources are the most stable and easy to develop resources, with low development costs, high returns, and easy realization. However, no one has yet conducted a comprehensive study on the underground storage space of closed/abandoned mines. Based on summarizing the research status of different types of storage (oil, gas, water, nuclear waste, seeds, etc.), this paper conducts an in-depth research on mine selection, sealing performance, storage space size, storage time and other aspects. Corresponding evaluation indicators and transformation technologies for underground space storage are proposed to formulate a theory and technology for ensuring the stability of underground space storage environment in closed/abandoned mines suitable for China's national conditions and natural geological conditions.
