Conventional salt mining creates large voids that disrupt geomechanical equilibrium, inducing subsidence pressures from overlying strata. This process, known as convergence, is the time-dependent closure of excavated spaces caused by salt-s viscoplastic behavior. Continuous convergence monitoring is critical for early detection of excessive strain, enabling timely mitigation to maintain structural stability and prevent hazards like water ingress and flooding. Due to the slow deformation rates of halite formations,...
