Research on Pressure Relief Hole Parameters Based on Abutment Pressure Distribution Pattern
Borehole pressure relief technology is an effective way to reduce the elastic energy in the surrounding rock of deep roadways, thereby reducing the risk of regional rock bursts. To avoid large deformation of the roadway caused by pressure relief holes with large diameters and insufficient pressure r...
