Resumen

CANBULAT, I.  y  VAN DER MERWE, J.N.. Design of optimum roof support systems in South African collieries using a probabilistic design approach. J. S. Afr. Inst. Min. Metall. [online]. 2009, vol.109, n.2, pp. 71-88. ISSN 2411-9717.

When designing coal mine roof support, it is necessary to account for the uncertainties and variability that inherently exist within the rock mass and support elements. The performance of a support system is affected by these uncertainties, which are not taken into account in the current deterministic design methodologies used in South Africa. The key to the design of a roof support system is a better understanding of roof behaviour and uncertainties that can be encountered during extraction. This paper sets out to develop a method that takes all uncertainties that exist within the rock mass and the mining process into account and provides a quantitative risk-based design methodology.
