developed a modified magnesium–aluminum-based solid waste CO 2 backfill material with a maximum compressive strength of approximately 5 MPa and a carbon sequestration efficiency of 6.8%, achieving the dual functions of mechanical support and CO 2 fixation. These studies highlight a clear trend toward designing backfill materials that synergistically combine structural support with thermal management, fire resistance, or carbon storage for more sustainable and safer underground mining operations.
