Multi-energy complementary system for co-associated abandoned mine and use method

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.
