Numerical simulation results of representative monitoring points.
(a) Calculated step-displacement curves for typical measuring points (class II isotropic surrounding rock)
(b) Calculated step-displacement curves for typical measuring points (isotropic surrounding rock excavation and timely support)
(c) Calculated step-displacement curves for typical measuring points (surrounding rock excavation with gentle dip fissure surfaces and timely support)
(d) Calculated step-displacement curves for typical measuring points (surrounding rock excavation with steep dip fissure surfaces and timely support)
(e) Calculated step-displacement curves for typical measuring points (surrounding rock excavation with weak interlayer and timely support)
(f) Calculated step-displacement curves for typical measuring points (surrounding rock of the cross cavern)
