dc.description.abstractThis paper describes a numerical approach to assess the stability of a borehole in fractured rock mass in deep ground using the Distinct Element Method (DEM), utilized by Universal Distinct Element Code (UDEC). A symmetric regular fracture geometry under non-hydrostatic stress state was used to investigate the effects of the different parameters on borehole stability. For this, effects of discontinuities orientation, spacing, aperture and friction angle and properties of intact rock on the stability of borehole were studied. The results of the DEM analyses have confirmed that the presence of fractures and the existence of high in-situ stresses are important contributory factors to borehole instability in fractured rock
