Description

technical field [0001] The invention relates to the technical field of expansion rock breaking, in particular to a dry ice powder dynamic rock breaking device, a dry ice powder dynamic rock breaking system and a dry ice powder dynamic rock breaking method. Background technique [0002] Blasting is often required in municipal transportation projects such as mining and stone mining, excavation of foundation pits, construction of tunnels and underground spaces, safe blasting removal of stubborn rocks / solitary rocks, and dredging of pipelines and other blockages. The blasting fracturing method has the characteristics of high efficiency and low cost, and is widely used in rock mass excavation such as mining engineering, underground transportation engineering, and water conservancy and hydropower engineering. However, the strong shock waves generated during the blasting operation will cause disturbance and damage to the rock mass in the near area, as well as vibration hazards in t...
