Abstract: Surrounding rock mass of deep red shale tunnel in Maluping mine were mostly vertical displacement after excavation under the condition of no support. Horizontal displacement and vertical displacement of red shale tunnel were suppressed effectively after adopted new extension type grouted rock bolt and base angle bolting. Rib spalling and roof caving problems of red shale deep tunnel of this mine were solved.

Key words: Deep red shale tunnel, Horizontal displacement, Vertical displacement, Bolt support
