Carbon dioxide exists as a liquid at temperatures below 31 degrees Celsius or at pressures greater than 7.35MPa, and begins to vaporize at temperatures above 31 degrees Celsius, and the pressure changes with temperature.
Taking advantage of this feature, liquid carbon dioxide is filled in the head of the cracking device, and the cracking device is used to rapidly stimulate the heating device, and the liquid carbon dioxide is vaporized and expanded instantly and produces high pressure, and the volume expansion is more than 600-800 times. When the pressure reaches the ultimate strength, the high-pressure gas breaks through and releases and acts on the rock mass and orebody, so as to achieve the purpose of expansion and cracking.
This technology overcomes the disadvantages of high destructive power and high risk in explosive blasting mining and precracking in the past, and provides a reliable guarantee for the safe mining and precracking of mines and rocks, and can be widely used in mining, cement, quarrying and many other industries.
At the same time, the carbon dioxide gas rapidly released during the cracking process of the carbon dioxide splitter has a cooling effect, and carbon dioxide is an inert gas, which can completely avoid the related accidents caused by the open flame caused by the shooting.
