Simulation study on pressure relief parameters of variable-diameter pressure-relief drilling
Conventional pressure-relief drilling with large diameters causes significant disturbance to shallow surrounding rocks in tunnels, leading to increased support costs. This study focuses on the variable-diameter pressure-relief drilling method and uses theoretical analysis and numerical simulation me...
