As many mines, quarries, and stone works now prohibit the use of traditional explosives for blasting, the static demolition rock industry has rapidly developed in major domestic mines and stone construction sites in recent years!

Static rock blasting(rock demolition) technology is a new type of technology that replaces traditional explosive blasting. There are currently three main types of static rock blasting(rock demolition) techniques:

The first type: carbon dioxide blasting (gas blasting)

Working principle: Carbon dioxide gas can be transformed into liquid under a certain high pressure. The liquid carbon dioxide is compressed into a cylindrical container (blasting cylinder) by a high-pressure pump, and the safety film, rupture disc, heat conduction rod and sealing ring are installed, and the alloy cap is tightened. Completed the preparatory work before demolition. Bring the blasting cylinder, the detonator and the power cord to the blasting site, insert the blasting cylinder into the borehole and fix it, and connect the detonator to the power supply. When the micro current passes through the high thermal conductivity rod, the high temperature will break down the safety film, and the liquid carbon dioxide will be vaporized instantly, and the rapid expansion will produce a high pressure shock wave to cause the pressure relief valve to automatically open. Body cracking.

Characteristics of carbon dioxide blasting(CO2 rock demolition system)

1. Gas is safer than explosives. It is not a civilian explosive product and does not require approval for transportation, storage and use.

2. There is no need for cumbersome procedures for explosive approval.

3. There is no destructive vibration and short wave during the rock demolition process, and the proportion of dust is reduced, which has little impact on the surrounding environment.

4. It can be used in complex operating environment, coal and mining fields.

5. Carbon dioxide is easy to purchase, and some devices can be reused.

6. Multiple blasting cylinders can be connected in parallel at the same time, with great blasting power and large individual rock after blasting.
