Mining cost of gas blasting equipment blasting mine

&Nbsp With the development of science, the tunnel excavation technology without blasting into rock is suitable for the tunnel to pass through special areas (such as high-rise buildings, traffic lines, places with active geological cracks around the tunnel, and places where the vibration generated by blasting will bring serious potential safety hazards or accidents)
A space of about 2m is taken by parallel water mill drilling method at the cutting surface of the tunnel, so that the construction personnel can facilitate the construction
There must be a part of empty surface around the section, and then drill several small holes on the expanded surface, split the surrounding rocks with rock splitting equipment or expansion agent, and transfer the broken gravel out of the tunnel
If the rocks are thick on the top of the tunnel and do not collapse, the free passage can be connected at one time, so as to speed up the overall project of the tunnel

Carbon dioxide blaster is a blasting technology with advanced concept, safe method and remarkable effect in the world
At present, it is widely used in boiler blockage removal, building demolition, blasting operation in special areas and so on
Advantages: 1
The carbon dioxide cracker adopts a unique design, which will not produce any open fire or spark during operation, which is more safe, and the transportation, storage and use do not need approval
2
Carbon dioxide blaster is a low-temperature cracker
After blasting, the surface temperature of carbon dioxide cracker and the temperature of carbon dioxide gas produced are very low, which can create an inert gas environment and essentially eliminate the possibility of gas explosion
3
There is no destructive vibration and short wave during blasting, and there is basically no dust, which has little impact on the surrounding environment
4
Carbon dioxide gas is easy to purchase, and some devices can be reused
5
The carbon dioxide cracker has the advantages of large blasting power, large coal throwing amount, large blocks and short throwing distance, which reduces the labor intensity of workers and will not cause accidents

Disadvantages: 1
High cost: the activator in the equipment is special and cannot be reused
When the output is not high, the blasting cost is high
2
High requirements: the blasting barrel filling process and on-site construction are complex, and the requirements for blast hole quality are high
3
Low output: if multiple rows of blasting cannot be realized, the number of blasting barrels for single blasting should not exceed two rows, and more than one row is easy to jam or blow up the blasting barrels
The main function of carbon dioxide cracking device is a new comprehensive technical equipment, which is widely used in many fields
The following is a specific introduction to its main functions

Carbon dioxide cracking device is a new comprehensive technical equipment, which is widely used in many fields
The following is a specific introduction to its main functions
2
Carbon dioxide cracking device is a compact It is a cracking technology with reasonable design, safe method and remarkable effect
On the one hand, the carbon dioxide cracker can meet the general needs of mine cracking, on the other hand, it can also provide new technologies and processes for coal mine gas prevention, coalbed methane extraction and mining under special conditions, so as to promote the healthy and safe development of China's coal industry
Today, I'll talk to you about the content of carbon dioxide cracking device, and then I'll talk about the three performance requirements of carbon dioxide cracking device The carbon dioxide cracker is designed according to the standards of the mining industry
It has the advantages of simple structure, high safety, controllable cracking energy and reusable
The following cracker manufacturers will take you to understand the three performance requirements of the carbon dioxide cracker, hoping to be helpful to you

1、 Pressure bearing capacity: the strength of the sealed cavity composed of liquid storage pipe, filling valve and energy release device of the crack maker shall not be less than 1
8 times the pressure
2、 Tightness: the filling valve filled with 1
5 times the pressure of compressed air should have no bubbles after being placed in water for two minutes
3、 Relief pressure: make it clear that the relief pressure of the carbon dioxide cracker is designed according to the requirements of 4
2
1 and 5
2
3
In addition to the above three performance requirements, there are also some other requirements, such as the four product advantages of carbon dioxide cracker
Carbon dioxide cracker is an important equipment in mining and other fields
It is mainly composed of main pipe, inflation head, energy discharge head, heating rod, shear plate, flying stopper and so on
The following are the four advantages of the carbon dioxide cracker
First, the carbon dioxide cracker has high safety performance and will not produce any open fire or spark in the working process, which will not cause potential safety hazards
2、 The carbon dioxide cracker has great power, large coal throwing amount, large blocks and short throwing distance, which reduces the labor intensity of workers

3、 The efficiency of the cracking equipment can be controlled by selecting different shear pieces
4、 The equipment will not produce any harmful gases such as smoke during operation, and will not cause harm to the operator's body
Carbon dioxide cracker is one of the equipment for mining based on the principle of thermal gasification and expansion of liquid carbon dioxide
It plays an important role in anti scour and ground pressure in mining
Rockburst is one of the complex dynamic phenomena under the mine
It poses a serious threat to underground safety production and is one of the very serious disasters in the process of underground mining
Using the prevention and control method of rock burst in heading face is a new idea and method, which solves the danger and inconvenience of the traditional way
Now it has become an important equipment in mining
Carbon dioxide blaster is a new comprehensive technical equipment, which solves the shortcomings of large destruction and high risk in previous blasting mining and presplitting
Are you satisfied with the main functions, three performance requirements, four product advantages, functions, advantages and disadvantages of the carbon dioxide cracker introduced above? Welcome to learn more product information
