Rock behavior around tunnels excavated in the same rock with various inclinations and "k" ratios has been investigated by numerical analysis employing the FLAC(3D) finite difference code. Stress distributions and displacements at the critical points of the tunnels in underground mining have been examined. Observed stress and displacement values with respect to the change in tunnel inclination and "k" ratio have been analyzed by using statistical methods employing "multiple regression analysis" in order to find out a meaningful correlation between the stress, displacement values and the inclination and "k" ratios. Statistical analyses have presented meaningful correlations giving mathematical equations whose dependent variable is displacement or stress and independent variables are tunnel inclination and "k" ratio.
