Carbon dioxide crackers are widely used abroad in boiler blockage clearance, building demolition, special area blasting operations, etc., and have obtained national safety certification. It is an internationally advanced blasting technology with advanced concepts, safe methods, and remarkable effects. It is effectively suitable for mine blasting needs. On the other hand, it is an effective and safe coal seam gas extraction technology and equipment. Therefore, the carbon dioxide cracker is a completely comprehensive technical equipment

The carbon dioxide explosion technology
Because it is a physical explosion It has technical advantages that other technical equipment cannot match,
,
, technical characteristics
,
The carbon dioxide cracker uses liquid carbon dioxide to vaporize and expand when heated, and quickly releases high-pressure gas to break Rock or coal falling, it solves the shortcomings of the previous blasting mining and pre-splitting, such as highly destructive and dangerous ore body crushing, and provides a reliable guarantee for safe mining and pre-splitting of mines. It is widely used in coal mines and non-coal mines. Liquid carbon dioxide can also prevent burning or damage caused by collision or falling from high altitude.
,
, Application fields of carbon dioxide crackers
,
According to the technical characteristics of carbon dioxide crackers, it can be widely used in coal mines, non-coal mines, open pits, underground, and blasting fields. , not suitable for blasting fields, and can be used as a seismic source for megaseismic detection, etc.
,
In the coal mine field, it can be used for deep hole pre-splitting blasting, coal (rock) tunnel excavation, and working faces. Coal falling, gas prevention and control, coal bed methane increase, enhanced coal water dust prevention, forced blasting and caving, coal bunker clearing and roadway repair (bottom drum), etc.
,
, technical processes
,
At present, carbon dioxide enhanced coalbed methane extraction technology, carbon dioxide cracker comprehensive gas prevention and control technology, carbon dioxide cracker working face excavation technology, Carbon dioxide cracker enhanced coal seam water dustproof technology, carbon dioxide cracker forced caving technology, carbon dioxide cracker dredging technology, carbon dioxide cracker demolition technology, carbon dioxide cracker fire prevention and extinguishing technology, etc.
,
, application effect
,
) In the soft
surface, the carbon dioxide may often exceed the limit and the carbon dioxide and other materials exploded by the full-section carbon dioxide cracker are used. There is less gas, no over-limit phenomenon has ever occurred, and there is a large safety space from the over-limit value.
,
(
,
) Other harmful effects are small
,
After the carbon dioxide cracker is exploded, not only will there be no shock wave, nor will there be any significant Loud explosions and smoke. Because it produces less toxic and harmful gases, no shock waves and no sound, it can create a good blasting working environment underground, which is beneficial to the physical and mental health of workers.
