Utilizing the physical principle of liquid carbon dioxide absorbing heat and vaporizing to expand, causing a rapid increase in pressure. It consists of steel pipes filled with liquid carbon dioxide, an activator, an energy release component, an inflation component, a点火 circuit connection component, and other auxiliary connection components. The liquid carbon dioxide vaporizes instantly upon heating by the activator, releasing high-pressure gas energy to fracture target materials such as rock, coal seams, and concrete. It addresses the drawbacks of high destructiveness, risk, and ore powdering in previous blasting and pre-splitting using explosives, providing a reliable guarantee for the safe mining and pre-splitting.
#Which Carbon Dioxide Blasting Equipment is the Best? Preparations for Carbon Dioxide Cylinder Explosions. Bring the explosive cylinder, detonator, and power cable to the blast site, insert the explosive cylinder into the drilled hole and secure it, then connect the detonator to the power source. As a microcurrent passes through a high-conductivity rod, high temperatures pierce the safety film, instantly vaporizing the liquid carbon dioxide and rapidly expanding to produce a high-pressure shockwave. This causes the pressure relief valve to automatically open, rapidly pushing the object or sediment outward by the geometrically equivalent shockwave. The entire process from start to finish takes only 0.4 milliseconds and operates at low temperatures, without mixing with liquids and gases in the surrounding environment, producing no harmful gases, arcs, or sparks, and is unaffected by high temperatures, humidity, or altitude. It has a diluting effect on gas during underground blasting, with no vibration or dust generation. Carbon dioxide is an inert gas and not flammable or explosive. The blasting process is a volume expansion process, a physical act rather than a chemical reaction.
Technically speaking, carbon dioxide blasting is not actually an explosion; it's a physical process where carbon dioxide gas transitions from a liquid to a gaseous state. However, due to the limitations of the technology and the shoddy production resulting from fierce market competition, some regional management authorities have banned its use.
The activator contains potassium perchlorate and other hazardous chemicals, making it a key focus for regulatory control by relevant authorities.
2. Some manufacturers' blasting pipes are of poor quality, especially disposable blasting pipes, which are prone to cause dangerous accidents.
Improper construction can lead to flying pipes, causing accidents.
Primary Application Areas: Carbon Dioxide Blasting in Tibet, Gansu, Sichuan, Henan, Heilongjiang, Jilin, Shanxi, Shaanxi, and other regions.
Utilizing its technical strengths, Carbon Dioxide Blasting has continuously improved and developed new solutions. In collaboration with university research teams, a new generation of Carbon Dioxide Blasting technology is now taking shape. This technology requires no activator or fracturing pipe, boasts low costs, enhanced safety and environmental friendliness, wider application scenarios, and reduced vibration and noise. The technology has already been successfully tested in iron ore mining operations.
