Influence of load-bearing wall material properties on building mine-induced dynamic response by Maciej Zajac, Krystyna Kuzniar, Tadeusz Tatara

“…Numerical analysis was based on a low-rise building with a typical wall-bearing structure. The finite element method (FEM) was used to create a three-dimensional (3D) model of the building. …”

Sealing and zero leakage characteristics of a high-pressure large-sized main drive based on active pressure compensation by Lifang ZHENG, Chao FANG, Fei MA, Tengfei CAI, Man YAO

“…To prevent the possible harm caused by high water pressure confining load to the sealing system, this study proposes a new main drive sealing method based on active pressure compensation, designs a sealing device suitable for the main drive sealing runway, proposes a zero leakage sealing evaluation method combined with percolation theory and a statistical contact model, establishes a micro- and macro-scale finite element sealing structure model, investigates the sealing contact and pressure resistance characteristics under different compensatory pressures and external loads, and reveals the evolution mechanism of sealing performance under the combined action of external cavity pressure and compensatory pressure. …”
