Mine backfilling is a crucial practice in mining and geology, involving the filling of excavated areas with suitable materials to provide structural support and minimize environmental impact. This process not only stabilizes the mined-out areas but also enhances safety by reducing subsidence risks. Various materials can be used for backfilling, including waste rock, tailings, and cemented paste fill, chosen based on their physical properties and compatibility with the surrounding geological conditions. Effective backfilling strategies are essential for sustainable mining operations, optimizing resource recovery, and mitigating ecological disturbances. Advanced techniques in geotechnical engineering and material science continue to evolve to improve the efficiency and environmental sustainability of mine backfilling practices worldwide.
