NUMERICAL SIMULATION OF ZONAL DISINTEGRATION OF ROCKS AROUND UNDERGROUND WORKING AT GREAT DEPTH
With the economy developing rapidly, rock engineering is becoming increasingly important. Zonal disintegration has an important effect on rock engineering construction. In this paper, the fracture evolution of zonal disintegration around two holes is represented using the numerical code RFPA3D-Parallel. The numerical results indicate that zonal disintegration of rock mass around a deep tunnel maybe found using high ground stresses parallel with the tunnel axis. The distance between tunnels has influence on the fractures of zonal disintegration. Zonal fracturing is not continuous; the spacing distances between adjacent fractures are approximately equal to the radius of the hole.
