Post-mining subsidence is a challenging problem in rock engineering. The modified Tributary Area Method (TAM) was used to estimate the lifetime of pillars. The effects of gradual deterioration was incorporated in the numerical modelling. The long-term stability of an abandoned room and pillar coal mine was investigated. This study showed that deterioration plays a significant role in the long-term stability of mining excavations.
