Abstract Numerical simulation of natural caving is conducted from meso-mechanics view through particle on the basis of method(PFM). A method is proposed to calibrate the parameters for the meso-mechanical model from meso-mechanics. The technique for initial stress field is also recommended. The proposed scheme has been applied to study the rupture evolution and contact force distribution after caving process at a mine in China. It will be helpful for research on caving in view of micro-mechanics.
