.... The authors report the outcomes of these experiments and discuss their implications in practice. 1. Introduction Rock dynamics is now one of the most important topics in the field of rock mechanics and rock engineering. The load bearing capacity of the rockbolts and rock anchors are governed by the shear...

... including trials with partial filling of the voids. This study has sought to examine in the laboratory the effects of partial and complete filling on the ultimate load bearing capacity and post-failure behavior of small, tall pillars using artificial material. INTRODUCTION Indian coalfields...
