A new path for pressure relief surrounding rock control of thick and hard roof combined blasting

Abstract Roof stability remains a critical challenge restricting safe and efficient coal mine production, particularly under thick and hard roof conditions where delayed caving of the goaf roof results in large suspended areas behind supports and pronounced dynamic pressure effects. Taking Jinjiazhu...
