In order to make better use of the large amount of resources and underground space left by abandoned coal mines and promote the transformation & development of energy-exhausted cities, a new technology for abandoned coal mine pumped storage power station is introduced. The overall reconstruction plan of power station construction is preliminarily analyzed. The necessity, feasibility and strategic significance of the construction of power station are pointed out. Combined with the existing construction machinery and equipment, the composition and application of power station infrastructure equipment group are discussed in terms of excavation and expansion support, earthwork, auxiliary machinery and intelligent robot. Then, in view of construction, operation and maintenance of the power station, the technical problems are summarized, such as stable support and sealing of water transmission system, throttling and drainage between multiple tunnels, anti-seepage and reinforcement of underground powerhouse, pumping and draining of natural groundwater around powerhouse, and efficient and safe transportation of personnel and large equipment. Finally, corresponding solutions are proposed for construction of underground pumped storage power station and special equipment.
