Pillar Strength And Design Methodology For Stone Mines

Pillar Strength . Pillar strength can be defined as the maximum resistance of a pillar to axial compression 9. In flat lying deposits, pillar compression is caused by the weight of the overlying rock mass. Empirical evidence suggests that pillar strength is related to both its volume and its shape 4, 6, 9. Numerous equations have been
