Combined process of integrating stoping-backfilling and carbon storage

A combined process of integrating stopping-backfilling and carbon storage, comprising the following steps:

• step 1, arranging a sensor for a roof pressure in an adjacent working face which is proximate to a fully-mechanized coal winning working face to collect data of a mine pressure of the adjacent working face and then obtain mine pressure data of the fully-mechanized coal winning working face according to the data of the mine pressure of the adjacent working face, determining that a strength of a backfilling body is larger than the roof pressure, and determining that a backfilling isolation interval is less than a weighting interval of the fully-mechanized coal winning working face;
• step 2, carrying out a coal mining operation on the fully-mechanized coal winning working face, and stopping the stopping when a stopping distance of the fully-mechanized coal winning working face reaches the backfilling isolation interval;
• step 3, after a scraper conveyor is pushed and a hydraulic support is moved, providing a backfilling tarpaulin behind the hydraulic support, and pumping, through a slurry backfilling pipeline, a backfilling slurry to a backfilling area along a support beam;
• step 4, injecting supercritical carbon dioxide into the backfilling slurry while injecting the backfilling slurry, and enabling the supercritical carbon dioxide to fully react with the backfilling slurry for 3-5 h, enabling the supercritical carbon dioxide to fully react with the backfilling slurry to solidify the backfilling slurry, wherein the solidified backfilling slurry is able to provide an early support with a strength of 1.8 MPa to 2.3 MPa;
• and
• step 5, continuing to advance the fully-mechanized coal winning working face by repeating the step 2 to the step 4 until the stopping of the fully-mechanized coal winning working face is all completed.
