Numerical Simulation and Application Research of Straight-Hole Cut Blasting with Empty Holes in Railway Tunnels

An empty hole in tunnel blasting and excavation serves as an auxiliary free surface and compensation space for blasting rocks, significantly influencing the blasting effects. The straight-hole cut blasting with an empty hole in a railway tunnel project was studied by theoretical analysis, numerical...
