    Abstract

    ![CDATA[Preventing roof collapse in underground tunnels, natural cavities or mines is a challenge to geotechnical engineering. To evaluate the roof stability of underground cavities two theoretical methods have been used in this study. The rock mass strength has been described by the Hoek-Brown failure criterion. The results of both methods were found to be consistent and have been presented as stability charts for a range of rock properties and geometries. The results of the analysis allow for prediction of roof collapse, but they can also be used to determine whether the failure surface that develops in the rock mass is local or extends through the full depth of cover. This is of signifi cant concern if there are overlying cavities and if estimating surface subsidence.]]
