Load bearing capacity of arch structure in unconsolidated layers

Scientific Reports, 2023
Coal mining inevitably results in the movement of overlying strata, with the upward formation of the strata leading to surface subsidence, causing irreversible impact on the buildings, land, and ecological environment. The movement and deformation of the

Movement Law of Overlying Strata with Loading Effect in the Large Space Structure of Deep Mines [PDF]

IOP Conference Series: Earth and Environmental Science, 2020
Abstract Under the action of high-stress field, overlying strata with load characteristics in large space structure formed by changes of working faces in deep mines intensifies the movement of the overlying strata on the working face, which may easily cause dynamic disasters at the working face.
