| Abstract: | Numerical simulation method was used to predict the subsidence rule of mountain aeolian-sand water-rich surface.Numerical simulation can reflect the constitutive relationship,geologic background of rock and soil and surface shape.Surface building module and movement and distortion calculation module were programmed with FISH.Mining subsidence rules under aeolian-sand water-rich surface in Yulin area were obtained and this method supply a new approach for subsidence prediction of mountain surface. |
| Keywords: | mountain surface prediction of mining subsidence numerical simulation FLAC3D |
