Qingtian carbon dioxide blaster gas expansion blasting equipment

&Nbsp At present, China's blasting design is still based on semi empirical and semi theoretical formula calculation
In addition, due to the complexity of blasting objects in structural stress state and damage characteristics, there are still great differences between theoretical research and practical application
The above factors lead to the lack of understanding of information technology development, insufficient investment in information technology application and unreasonable investment structure
This can not guarantee the coordinated development between the construction, maintenance and update of information system and the development and utilization of information resources, which will affect the healthy development of information construction in engineering blasting industry and improve competitiveness through Informatization
The upgraded product of blasting equipment is a new favorite of geotechnical engineering
It can completely replace the innovative products of Zha Mining Mine & mdash& mdash; Gas blasting, also known as carbon dioxide blasting, is a high-end mining equipment that can replace explosive blasting and an expert in silent rock blasting
The successful development of new gas blasting equipment will mean that mining will gradually become a reality instead of blasting rock with explosives
Carbon dioxide blasting equipment uses the principle of liquid carbon dioxide phase change blasting technology and is composed of liquid carbon dioxide filling system, blasting system, joint conversion system and heater system
Among them, the grouting machine, blasting pipe, tightening machine and energy relief valve have applied for Guojia utility model brick benefit
Heating system activator, the equipment is safe and environmentally friendly, easy to operate, excellent performance and high cost performance

Compared with traditional blasting, gas blasting equipment has the following advantages:
1
Burst No spark is exposed during the breaking process;
2
Low pressure initiation (9V) is safer than traditional initiation (1800V);
3
There is no destructive shock or shock wave, which reduces the probability of inducing gas outburst;
4
There is no need to conduct blasting inspection
It can be accessed after blasting and can be operated continuously;
5
There is no difficulty in handling Squibs, which is safe and simple;
6
Burst The breaking power is between 100 ~ 300mpa, which can be regulated and exploded The breaking direction is controllable

Main application fields:
1
In the non blasting mining of medium and large stone yards, larger stones can be obtained by carbon dioxide blasting

2
Open pit mining of gold, silver, lead, lead, aluminum and other metal mines, combined with DTH drilling, using carbon dioxide gas blasting can quickly blast the ore body, which is safe, efficient and vibration free

3
When digging a subway tunnel under an urban building, if a huge rock needs to be blasted and the binding agent cannot be used, the blasting rod can be used to effectively blast the rock

4
The blasting and removal of large rocks in geotechnical engineering can replace air pick, crushing hammer and expansive agent for non blasting excavation of mountains
