The invention discloses a gravity energy storage system and method utilizing an abandoned mine shaft, and relates to the technical field of energy utilization, the gravity energy storage system comprises an energy conversion unit, a vertical shaft lifting unit and a ground weight storage unit; the vertical shaft lifting unit comprises a steel wire rope, an electric permanent magnet lifting tool, a head sheave, a winding drum, a gearbox and a shaft. The ground weight storage unit comprises a transfer device, an arc-shaped slide way, a weight limiting baffle, a drainage baffle, multiple thin cylindrical weights and a supporting column, energy storage is conducted on the system in the electricity trough period, a steel wire rope is driven to be lowered through an electric power generation all-in-one machine, and the multiple weights in a shaft are lifted through an electric permanent magnet lifting tool at one end of the steel wire rope; the energy is conveyed to a plurality of arc-shaped slideways by the transfer device for energy storage; in the peak period of power utilization, the system is subjected to energy release, gravitational potential energy acts to drive the electric power generation all-in-one machine to generate power, and then the gravitational potential energy is converted into electric energy through the transformer substation. The recycling of the abandoned mine shaft is realized, and the problem of storing a plurality of heavy objects is solved.
