AN EXPERIMENTAL CRITERION TO DETERMINE PILLAR STRENGTH IN SALT MINES
Abstract
Most of the salt that is being consumed in Iran is produced through stope and pillar mines, located in north of the central desert of Iran. The very large stopes have been excavated for applying open cut loading and hauling machines, so that those stopes have to be supported by large pillars. Therefore, the excavation ratio and stability considerations should be studied as two special cases in these mines. To determine the pillar’s strength, in this paper, four of the largest mines have been studied. An experimental criterion has been presented based on field investigations and mechanical characteristics of the rock, using back analysis. Finally, the presented criterion has been compared to the existing criteria and results have been reported.
