AB  - Blasting operations generate seismic effects in underground mines. These effects apply additional dynamic loads on the support system, which should bear both static and dynamic loads. The static loads are caused by the weight of the superincumbent strata while the dynamic loads occur as a result of blasting in the mining area. Identification of the origin and determination of the support system behavior in natural frequencies is crucial in assessing the stability of underground mines. This is because resonance occurs when a support is vibrated with its natural frequencies which can cause a vibration with the maximum amplitude and subsequently cause extreme deformations. The mechanism of support system deformation during dynamic load displacement has been studied and numerical simulation for the impact of the dynamic loads on stability of supports is carried out using finite element method.Finally, the paper introduces a simple technique for improving stability and safety of mining operations. Results obtained and the methodology adopted in this research, can help the mining design engineer to decide on adequate support for active mining operations.
