A PHOTOELASTIC - MODEL STUDY OF STRESS DISTRIBUTION AND ROCK FRACTURE AROUND MINING EXCAVATIONS

A THREE-DIMENSIONAL PHOTOELASTIC-MODEL STUDY OF TWO HORIZONTAL MINING EXCAVATIONS WITH A CENTRAL PILLAR IS DESCRIBED. DETAILS OF EXPERIMENTAL TECHNIQUES ARE GIVEN AND STRESS DISTRIBUTIONS, ROCK-FRACTURE INITIATION ZONES AND THE DIRECTIONS OF SUBSEQUENT FRACTURE PROPAGATION AROUND THESE EXCAVATIONS ARE DETERMINED. IT IS SHOWN THAT THE TECHNIQUES ADOPTED FOR THIS INVESTIGATION OFFER REALISTIC MEANS FOR COMPARATIVE DESIGN STUDIES OF BEST SHAPE AND LAYOUT OF MINING EXCAVATIONS. /AUTHOR/
