With the increase of the number of closed and abandoned mines in the world, it has become an urgent need to study the assessment and reuse of various resources of closed and abandoned mines, as well as the transformation and development mode of mines. Various sources of data are used to identify the types of closed and abandoned mine resources, the classification system of aboveground and underground resources of mines is established. The calculation method of available space of ground buildings, underground tunnels and shafts, and the estimation method of underground residual coal quality are given, the determination method of transformation mode of closed and abandoned mines is proposed. The transformation and utilization modes of closed and abandoned mines in China and abroad are compared. Taking a closed mine in Shaanxi Province as an example, the optimal transformation mode is determined and the planning scheme is given. The main conclusions are as follows: (1) Aboveground resources of closed and abandoned mines mainly include surface water, idle land, mining equipment, and buildings of industrial squares and living areas, while underground resources mainly include groundwater, residual minerals, underground space and mining equipment left underground. (2) The aboveground development and utilization modes of closed and abandoned mine resources include mine park, mining museum, industrial relics, etc. while the underground development and utilization modes include underground storage, underground laboratory, energy development, etc. (3) It is calculated that the building space volume of a closed mine industrial square in Shaanxi Province, China is up to 1.04 × 105 m3, the available underground space volume including shaft, roadway, chamber and yard is 1.18 × 105 m3, and the mass of underground residual coal is nearly 56 million tons. (4) Based on the evaluation of suitability for mine transformation, three transformation modes have been identified for a closed mine in Shaanxi Province, China. Through the comprehensive benefit evaluation, the optimal utilization mode for the mine has been determined as mine park and mine museum, and a preliminary planning scheme is proposed. The research on the reuse of the remaining resources of closed and abandoned mines provides a new idea for the transformation and sustainable development of resource-depleted mines, which is of great significance for the realization of the global carbon peak and carbon neutrality.
