1. A multi-energy complementary system for a co-associated abandoned mine, wherein the multi-energy complementary system for a co-associated abandoned mine comprises:
a mining mechanism, comprising:
a storage unit;
a uranium transport pipe;
a liquid transport pipe;
a pump;
a coal seam;
a return airway located in the coal seam,
a haulage gateway located in the coal seam,
a surface layer;
an ore-bearing aquifer located below the surface layer; and
a pumping pipe having a lower end arranged in the ore-bearing aquifer;
a grouting mechanism, comprising:
solid waste slurry;
a pump chamber;
a treatment unit;
a key layer located between the ore-bearing aquifer and the coal seam;
a separation area located at a lower part of the key layer;
a grouting pipe arranged in the separation area; and
a mixed slurry pipe having a first end connected with the treatment unit and a second end connected with the grouting pipe; and
an energy mechanism, comprising:
an above-ground water storage tank;
a solar panel arranged on the above-ground water storage tank;
an underground reservoir;
an underground space in which electrolysis occurs;
a water pumping pipe having a lower end arranged in the underground reservoir and an upper end arranged in the above-ground water storage tank;
a goaf arranged in the coal seam;
a compressed energy storage unit arranged in a middle of the goaf and adjacent to the underground reservoir and the underground space;
a gas collecting pipe connected with the compressed energy storage unit and the storage unit;
a delivery pipe connecting the compressed energy storage unit with the underground space;
wherein the surface layer is sequentially provided with the storage unit, the pump, the pump chamber, the treatment unit and the above-ground water storage tank,
wherein the uranium transport pipe and the liquid transport pipe are sequentially connected with the storage unit and the pump,
wherein the pump chamber is connected with the mixed slurry pipe and the treatment unit, and
wherein the solid waste slurry is placed in the treatment unit.
