Study on the fracture characteristics controlled by filling ratio in cut-and-fill mining

To mitigate surface subsidence and stope instability induced by an insufficient filling ratio in cut‑and‑fill mining, this study investigates overlying strata fracture characteristics and instability mechanisms by means of similar material simulation, PFC numerical modeling, and...

Effect of Mineral Composition on CO2 Mineralization and Mechanical Strengthening of Synthetic Tailings

To elucidate the influence of mineral composition on CO2 mineralization and mechanical reinforcement, three synthetic tailing systems representing felsic, high-calcium silicate, and magnesium-carbonate compositions were prepared using a full-component reconstitution approach. The...
