Numerical simulation for geotechnical material of mine stope by mechanics and deformation performance Conference Paper

abstract

• This paper is focused on the mechanics and deformation performance of mine stope after excavation. The deformation performance is described by the settlement of stope roof, and the mechanics performance is described by the plastic zone of rock mass surrounding stope. The numerical calculation software FLAC3D is used to simulate the deformation and failure situation of the rock mass surrounding complicated large underground stope. In the calculation, the excavation procedure for the stope is simulated. The mechanical method has been adopted to establish the analysis on the stope stability, the results are in accordance with the actual situations, and can help to more accurately predict location of failure. The conclusion can give some guidance for the real practice.
