FLAC3D simulation for deformation failure characteristics of mine waste accumulation slope of a coalmine

The mine waste accumulation slope of a coalmine is a kind of special manual accumulation body,its deformation-failure has certain characteristics.The mine wastes and clay layer under them bear much strong strain-softening characteristics.The paper makes 3D numerical simulation for deformation failure characteristics of mine waste accumulation slope of a coalmine in Sichuan Province using FLAC 3D software,the results show:① Recurring the process of deformation failure of the slope is feasible by ...
