Carbon dioxide expansion rock cracking technology

As we all know, explosive blasting is one of the main causes of major accidents. Gas explosions caused by explosive blasting account for more than 40% of such accidents (also account for more than 30% of all coal mine gas and dust explosion accidents). In the case of gas, water accumulation and ground stress concentration in the blasting area, blasting will also cause gas outburst, even gas explosion, water inrush disasters (more than one-fifth of coal mine water inrush is caused by blasting), rock burst, etc. . In other fields, when explosives explode, they often cause great damage to surrounding buildings and people. For example, it can lead to the collapse of buildings, damage to power transmission lines, and loss of life. This is determined by the characteristics of explosives. The explosion process of the explosion is completed in a very short time. A chemical reaction occurs instantly to produce a powerful impact (above 1000Mpa-5000Mpa). This kind of impact can form a strong vibration, reaching the intensity of "earthquake above magnitude 3", even several kilometers away.
