ABSTRACT

ABSTRACT: Two-dimensional and three-dimensional DEM programs, UDEC and 3DEC, were used to investigate the mechanical stability of the conceptual design of deposition drift and deposition holes constructed in a crystalline rock mass. From the simulations, the influence of discontinuities, number of deposition holes, and deposition hole interval on the stability of deposition drift and deposition holes could be determined. It was also found that that the deposition hole interval changed from 8 m to 3 m does not influence on the mechanical stability of the deposition drift.
