Resumo

POTVIN, Y.  e  WESSELOO, J.. Towards an understanding of dynamic demand on ground support. J. S. Afr. Inst. Min. Metall. [online]. 2013, vol.113, n.12, pp. 913-922. ISSN 2411-9717.

The proper understanding of the functioning of ground support under dynamic loading and the current approaches to designing of dynamic support are plagued by a great deal of uncertainty and lack of knowledge. This applies equally to the understanding of the support capacity as well as the demand placed onto the support due to dynamic loading. This lack of understanding currently leads to a case of design indeterminacy. This paper does not aim to solve this problem of design indeterminacy but to explore some of the issues that need consideration to obtain a better understanding of the dynamic demand on ground support systems.

Palavras-chave : ground support; dynamic loading.
