This paper presents a numerical study of the interaction of twin, horizontally aligned openings, deeply embedded in salt rock. Complex three-dimensional (3D) creep analyses were carried out using the Finite Element (FE) method. Findings show that opening interaction appears to develop with time, whilst increasing the time period between excavations causes a slight reduction in interaction. The FE model was then used to back analyse openings at Boulby Mine, North Yorkshire.
