... contributing to the regional behaviour of the rock mass are overlooked. In many cases the pillar system is the source of seismicity. In this paper, the influence of mining losses (potholes) and the use of sidings are discussed as possible contributors impacting on crush pillar behaviour. A limit equilibrium...

... cables placed around mesh-wrapped pillars as an effective means to improve pillar stability and control mine deformation. In the present study, and with the background of available laboratory uniaxial compressive strength tests on cabled samples and empirical knowledge of pillar behaviour, we present the...

... empirically derived formulae to a project area, it is assumed that the relationship between the loading system and pillar behaviours is similar to that in areas for which the formulae were derived. However, the same pillar strength formulae appear to have been applied on most of the South African gold...
