“…Early applications of risk concepts to underground mining geomechanics evaluated the influence of parameter and other input variability on the probability of failure using the general approach illustrated in Fig. 2 (McCracken and Stacey, 1989; Tyler et al , 1991; Pine, 1992). The consideration of the cost implications of the calculated probabilities of failure, often using cost-benefit analysis, followed slightly later (Brummer et al , 1993; Suorineni et al , 1995; Diederichs and Kaiser, 1996; Horsley and Medhurst, 2000).…”

Deep Mining 2012 is the sixth in a series of international seminars on deep and high stress mining which began with a seminar held in Perth in November 2002, almost a decade ago. The early announcements for this seminar listed 10 seminar themes. This paper seeks to make contributions to the discussion of progress made in four of these themes -geomechanics risks, risk assessment and management, rock behaviour under high stress, and numerical modellinglargely, but not only, through a review of the papers published in the proceedings of the five previous seminars. Particular emphasis is placed on the risks associated with the new generation of block and panel caving operations or 'super caves'. Some remaining challenges in the four theme areas discussed are also identified.

“…Young (1993) developed a method to estimate the localized probability of slope failure for open pit slopes in fractured rock masses by combining geostatistical modeling techniques with key block analysis. Tyler et al (1991) employed a probabilistic method for predicting the formation of key blocks in South Crofty tin mine. Tyler and Trueman (1993) conducted a study of probabilistic key-block analysis for support design and effects of mining-induced stress on key-block stability.…”

Tunnel stability analysis is a geotechnical engineering problem characterized by many sources of uncertainty. In such cases, rock and soil characteristics could not be defined by deterministic values and probabilistic technique would be as a suitable alternative. Naien water transporting tunnel is a circular tunnel with 6 m in diameter which is being excavated in such conditions and it is almost impossible to analyze the tunnel stability deterministically. To use probabilistic analysis, the best fitted distributions to rock mass characteristics were first obtained. Using Monte-Carlo simulation method and considering four support systems, the distribution of factor of safety was obtained for each support system. To select the best support system, TOPSIS multi-attribute decision-making method was used by considering five criteria for each support system ( as alternatives) including: probability of failure (using probabilistic method), factor of safety (using deterministic method), maximum displacement, cost and factor of applicability. The results of this research emphasize that the deterministic or probabilistic alternatives could not be separated by such comprehensive technique for stability analysis and should be interpreted together. At last, using such TOPSIS application associated with stability analysis techniques can assist the engineers to effectively evaluate the support system alternatives for a tunneling project.
