The Infl uence of the Form of a Salt Mine on the Displacement of the Ground Surface Author: G. Kortas
Relations between form structure of multi-level, room and pillar salt mine and ground surface displacement
distribution were found on the base of numerical model researches. It was noticed that the
displacement distribution depends on structure slenderness which infl uences rock mass conditions of
equilibrium and volumetric strains. For a mininig fi eld represented by 2D + t model relations between
though surface in vertical cross-section and aerial convergence of all chambers were defi ned. The 2D + t
viscous-elastic model of the rock mass were applied in FEM model researches. |
