Abstract:

Geomachenical models are able to solve the problems which take into asccount layers’ features such as heterogeneity and anisotropy of rock. The obtained characteristics like stress distribution, deformation, the progress of damaged regions, and their intensity depend on structure, arrangement of layers, and shape of objects. This paper presents the application of geomachenical models on analyzing and predicting movement and deformation of rock considering the relationship with slope angle and depth of seams, as well as excavation methods. From the result achieved from the FLAC 2D software, it is confirmed that geomachenical models can be used to predict the law of movement and deformation in underground mining in Vietnam.
