Abstract

A virgin chromite orebody located in eastern India is planned to be extracted by sub-level open stoping method. The portal of the decline and vertical shaft is planned to locate in the footwall side of the orebody to access the deposit. Design of proper supporting system for the underground stope is important for the safe extraction of orebody. In this paper, two dimensional finite element modelling techniques have been employed to determine the stress and displacement distributions around the stope and rib pillar and also estimated the tensile zone that may occur in the crown, sill and rib pillars. Based on development of the stress, displacement and tensile zone in the roof and rib pillar; roof bolting grid pattern is established.
