Study on the Influence of Notched Empty Hole Parameters on Directional Fracture Blasting Effect

Study on the Influence of Notched Empty Hole Parameters on Directional Fracture Blasting Effect

Placing empty holes between charging holes is widely used in blasting engineering to achieve directional fracture blasting. Studies have shown that the presence of a notch along the empty hole wall enhances stress concentration and supports improved control over crack propagation. The notch angle an...
