Dingli CO2 rock breaking system is a new rock breaking technology that can replace explosive blasting. Our company started research and development in coal mines in 1996. This technology is mainly developed to avoid explosion accidents caused by flames generated by explosive blasting in high gas mines. After three years of numerous failures and thousands of experiments, the 51# rock-breaking steel pipe was finally successfully developed. In 2014, the carbon dioxide rock breaking system was further improved and upgraded, the 108# rock breaking steel pipe was developed for open-pit rock breaking. There is no vibration, shock wave, open flame or harmful gas when the carbon dioxide rock breaking system works, which is safe and environmental. The steel pipes are reusable, which helps to reduce the cost. The advent of the 108# CO2 rock breaking system perfectly solves the problem of prohibition of blasting in quarries and mines and the low efficiency of excavator hydraulic breaker. Now the carbon dioxide rock breaking system has been widely used in quarries, mines, highway construction, building foundation, tunnel excavation and other fields.
