Abstract

In order to maximize mining the underground resources and ensure the safety of the buildings and structures located in ground, the ground subsidence and movement induced by transition from open pit to underground mining of Xinqiao Mine was studied based on a three-dimensional model established by MIDAS/GTS. Analyse results showed that the largest value of surface tilt (i), curvature (K) and horizontal deformation (ε) are 0.640mm/m, 0.012×10-3/m and 0.503mm/m, which lower than the structures and buildings objects protection level and the allowable deformation value corresponding. The ground subsidence and movement induced by transition from open pit to underground mining will don't endanger the buildings and structures located in ground, which provide a theoretical basis for prediction and safety analysis of Xinqiao Mine's ground subsidence.
