COMBINED PROCESS OF INTEGRATING STOPING-BACKFILLING AND CARBON STORAGE
Disclosed is a combined process of integrating stoping-backfilling and carbon storage. The combined process includes the following steps of: determining a cyclic interval of a working face through measured data of a mine pressure of a fully-mechanized coal winning working face; when the stoping distance of the fully-mechanized coal winning working face reaches a backfilling isolation interval, providing a backfilling tarpaulin behind a hydraulic support, and pumping, through a backfilling pipeline, backfilling slurry to a backfilling area along a support beam; when the area is backfilled with the backfilling slurry, injecting supercritical carbon dioxide into the backfilling slurry; and allowing the supercritical carbon dioxide to fully react with the backfilling slurry to solidify the backfilling slurry.
