Abstract: Mine development in complex geological conditions is associated with the risk of
mine stability loss. Geological features such as dykes are characterized by higher strength
and a tendency to undergo brittle fracture under the influence of the tectonic component of
stress. In this study, numerical simulations were conducted to analyze the zone of influence
of the dyke and the extent of brittle fracture zones on the hanging and footwall sides
relative to the dyke. The results indicate that the dyke’s influence zone increases when
the dyke is situated in a gentle slope, and the size of the brittle fracture zone depends on
the hanging and footwall sides of the rocks, as well as the dip angle of the dyke to 30%. It
was observed that the rate of change in the brittle fracture zone varies non-linearly with
increasing stress level and then stabilizes once the stress reaches the ultimate strength of
the material. Consequently, the design of mine workings requires adjustments in support
methods and stability assurance techniques within the dyke’s influence zone.
