Advances in Materials Science and Engineering, Volume 2023, Issue 1, 2023., 2023 The unloading failure process in mining engineering scenarios is similar to the loading failure process at different loading rates indoor. To clarify the relationship between the mechanical properties of backfill and the loading rate, a particle flow code 2D‐based numerical simulation was performed to establish the backfill model, and tests involving ...

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 In deep hard‐rock mines, the failure of subsurface structures (e.g., tunnels, stopes, and shafts) has been a significant problem affecting mining safety due to the high‐stress environment. In this paper, the mechanism of structural failure and instability is discussed, and optimized excavation methods are proposed for stress control in deep gold mines.
