Abstract

      projects are needed to investigate the probability of falling rock. Coordinates of the discontinuities are important parameters influencing this falls. Most of the studies conducted to evaluate the probability of rock falls without taking into account the reliability requirements. This study uses a probabilistic analysis methods attempt to determine the falls of stone in the north wall of the Gol-e-Gohar mine and result of this study was to compare the final state. The results showed that the falls determined using conventional definitive methods in case of joint sets forming poles in the grid falls is stereonet to be are quite reliable but in the case of joint sets forming poles falls close to the border stereonet grid and the reliability of the grid are reduced. In this case, a more appropriate method of analysis reliability analysis definitive acts and can be replaced. By replacing the reliability analysis method, instead of the deterministic analysis method, the calculation of the coordinate of the discontinuities can be measured by more accurately assess.
