| Abstract: | Based on the surface investigation,geophysical exploration and other comprehensive means and theoretical analysis,using the deformation mechanism of overlying strata in mine-out area,structure characteristic of rock,characteristic of geometric elements and deformation time effect,a geomechanical model for mechanical analysis is established.Using a variety of mathematical mechanics methods and advanced three-dimensional numerical simulation technology,the influence mechanism and strength of overburden deformation on slope stability in mine-out area are analyzed and the stability of the slope is checked.Through the engineering judgment,the checking result is reliable,and according to this,the design of slope treatment is carried out. |
