Use of Salamon's stability criterion in underground mine design can prevent the occurrence of catastrophic domino-type pillar failure. Evaluating the criterion requires computation of the local mine stiffness and knowledge of the postfailure behavior of pillars. This paper summarizes the status of the practical use of this important criterion and suggests important research to improve our capabilities. Analytical and numerical methods are used to compute the local mine stiffness. Work to date… CONTINUE READING
