Exploring the time-dependent behaviors of the rock mass roof of tunnels in open underground spaces of coal mines through numerical investigation.

ABSTRACT: The stability of rock mass roofs in open underground spaces of coal mines in Iran is a critical concern, as it can have significant implications for mine safety and productivity. The rock mass roofs are prone to degradation and failure due to various factors, including mining-induced stress, water infiltration, and mechanical damage. However, there needs to be more understanding of the time-dependent behaviors of these rock mass roofs. This study aims to investigate the time-dependent behaviors of rock mass roofs in tunnels of open underground spaces of coal mines in Iran using numerical simulations. A 3D numerical model was developed using finite element modeling. The model was validated using field measurements and laboratory tests. The study revealed that the rock mass roof exhibits sig
