Protection of Vertical Shafts in Deep-Level, Hard-Rock Mines


The layout of mine excavations and protection pillars necessary for the exploration of tabular mineral deposits in a deep level hard rock environment can be effectively determined by the use of the theory of elasticity. The derivation of design parameters based on elastic analyses of mining configurations and "in the mine" observations of damage, has been used to derive semiempiric parameters which are of value in determining the size of reef pillars to protect vertical shafts, as well as to permit the prediction of the stabilty of existing shafts as affected by future mining operations. It is suggested that the design approach described in this paper can be adopted in deep mines in North America, provided there is a correlation between the elastic analyses and underground physical conditions.
