Working Principle
The carbon dioxide gas can be transformed into a liquid state under a certain high pressure, and the liquid carbon dioxide gas is compressed into a cylindrical container (blasting cylinder) by a high-pressure pump and filled with a safety film, a ruptured disc, a heat conduction rod, and a sealing ring, and the alloy cap is tightened to complete the pre-blasting process. preparations. Take the blasting tube, detonator, and power cord to the blasting site, insert the blasting tube into the drill hole and fix it, and connect the power supply of the detonator. When the micro-current passes through the high heat-conducting rod, a high temperature is generated to break down the safety film, and the liquid carbon dioxide is vaporized instantly, and the rapid expansion generates a high-pressure shock wave, which automatically opens the pressure relief valve. body cracking.
Advantages
1) Gas is safer than explosives. It is not a civil explosive product, and transportation, storage, and use do not require approval.
2) There is no need for cumbersome procedures for the approval of explosives and strict supervision by the public security department.
3) There is no destructive vibration and short wave during the blasting process, the proportion of dust is reduced, and there is little impact on the surrounding environment.
4) It can be used in complex operating environments, such as coal mines and mines.
5) Carbon dioxide gas is easy to purchase, and some devices can be reused.
6) Multiple blasting tubes can be connected in parallel at the same time, the blasting power is great, and the rock individual after blasting is large.
Disadvantages
1) Low efficiency
The steps are too cumbersome and cannot be blown up several times a day, and the more links there are, the more chances of problems will occur. Such as filling, wiring, sealing, and other links.
2) Air surface requirements
It is effective to use the free surface, and it is not suitable for deep foundation pits or working surfaces with a poor volley.
3) Low output
If multiple rows of blasting cannot be realized, the number of blasting tubes for a single blast should not exceed two rows, and if more than one row, the blasting tubes will be easily jammed or damaged.
4) High cost
The activator that it uses is a special-purpose, disposable article that also causes high blasting costs when output is not high.
5) high requirements
The blasting barrel filling process and on-site construction are relatively complicated, and the quality of the blast hole is required to be high.
6) Noise and safety
Although the blasting vibration is not strong, the sound is more obvious after all. If you want to use it in the surrounding residential buildings and buildings, you should try to ask the local safety supervision and environmental protection for permission.
