Influence of joint angles and in-situ stress on blasting effects in layered rock mass

Key Points

• Blasting effects vary significantly based on joint angles and in-situ stress.
• A detailed analysis shows changes in stress distribution during blasting, affecting rock fragmentation.
• Assessment of blasting conditions highlights the importance of geological structure for effective rock removal.
• Results call for consideration of joint angles and in-situ stress in future blasting operations, indicating the need for tailored approaches.
