In order to investigate on cracks propagation of the coal under column charge blasting subjected to geostatic stress, the damage constitutive model was established by considering tension and compression. The improved damage constitutive model was embedded in the FEM software to study the mechanics of cracks propagation coupled by blasting loads and geostatic stress. The precision of simulation is proved because the numerical results are in good with model experiments. The results show that the interaction of the compression wave and unloading wave yield cracks in the coal. The cracks are somewhat inhibited by geostatic stress. The direction of cracks is in accordance with the major principal stress.
