Overlooking a mining area, the vast underground voids resemble hidden scars on the earth. They are not only hotbeds of safety hazards but also potential sources of ground subsidence and water pollution. Mine backfilling is precisely the regenerative technique that heals these "scars": injecting specialized materials into kilometer-deep wells, it acts like an "artificial skeleton" for the mine, supporting the crumbling rock formations. It also acts like stitching together an "ecological wound" in the earth, sealing away harmful substances and rebuilding an underground ecological barrier.

Mine backfilling, a core technology in mine ecological restoration, is quietly ushering in a green revolution. By backfilling the mine with a scientifically formulated mix of solid waste, it not only effectively addresses the challenges of ground subsidence and environmental pollution left behind by traditional mining, but also promotes resource recycling.
