Abstract

Based on the inducement mechanism of floor water-inrush by high confined water and rock nature, and aimed at establishing rock mass mechanical models, numerical simulation tests with FLAC3D are conducted to reproduce the formation and evolution of water-inrush channel advancing with workface in high water pressure mining. Numerical analysis results show that the volumetric strain of rock crack face is affected by the interaction between stress field and seepage field, which provides new knowledge on the formation and evolution characteristics of floor water-inrush channels under high pressure.
