Carbon dioxide gas explosion operation process

Carbon dioxide gas blasting is a safe, environmentally friendly and efficient blasting method, suitable for underground mines, tunnels, building demolition and other fields. The following will introduce in detail the operating procedures and precautions for carbon dioxide gas explosion.

• 

• 1. Preparation of blasting area
  
  Before carrying out carbon dioxide gas blasting, it is necessary to accurately determine the blasting area and blasting target, and formulate a corresponding blasting plan. Safety signs and warning signs should be set up in the blasting area, and people around should be kept away from the blasting area.
  
  2. Gas filling
  
  Inflate carbon dioxide gas into the blast hole or blast pipe. You can use a gas bottle or a gas generator for inflation. Before filling with gas, you need to check whether the inflation pipe is smooth and whether the gas generator is worKing properly. When performing the inflation operation, reasonable inflation pressure, inflation time and other parameters should be set according to the actual situation, and ensure that the inflation amount is sufficient to achieve the blasting effect.
  
  3. Explosion parameter settings
  
  Set reasonable blasting parameters according to the actual situation, including inflation pressure, inflation time, etc. When setting blasting parameters, factors such as the hardness of the blasting target, rock mass structure, and environmental impact after blasting need to be considered.
  

• 4. Gas release
  
  After confirming safety, trigger the gas generator or open the gas bottle to release carbon dioxide gas. When releasing gas, ensure that surrounding personnel have evacuated to avoid safety accidents.
  
  5. Explosion effect inspection
  
  After waiting for a certain period of time, check the blasting effect. If the blasting effect is not satisfactory, secondary blasting can be carried out. At the same time, cleaning work should be carried out to remove stone chips, dust and other materials generated by the explosion to ensure the safety of the construction site.

• 
  

• It should be noted that when conducting carbon dioxide gas blasting operations, appropriate blasting parameters should be selected according to the actual situation to ensure safety, and relevant operating procedures and safety regulations should be followed. At the same time, management and supervision of blasting sites should be strengthened to ensure that the construction process is efficient, safe and environmentally friendly.
