Abstract

To explore the impact characteristics of filling body on the both sides of stope under the dynamic loads in a deep underground metal mines, based on trock mechanical parameters experiment, dynamic was loaded by measured and de-noised blasting vibration monitoring-curve, response parameters development regularity of filling body were achieved and the dynamic characteristics was revealed by FLAC3D: filling body which first excavated show have relatively large dynamic stress and displacement, plastic zone and shear strain increment of the eastern increases with the time and then tended to be stable; plastic zone is more obvious in the root and floor of the first excavated filling body under dynamic impact effect. This is because of disturbance accumulation effect and filling technology. It shows that, surrounding rocks stability affected by mining sequence to a certain extent and blasting design after adjusting parameters based on impact characteristics analysis controls blasting boundary effectively and improve the stope stability
