Description
Technical field
This utility model relates to demolition set technical field, particularly relates to a kind of safety carbon dioxide blaster.
Background technology
Some developed countries such as high pressure pneumatic component is a kind of without explosive blasting, twentieth century beginning of the sixties, the U.S. start
Study this physics blasting procedure, utilize the plant equipment such as compressor or produced by physical change (such as liquid becomes gaseous state)
Gases at high pressure, install high pressure pneumatic component pipe in coal, rock mass, manually and motor-operating mechanism, make the height in blasting cartridge
Calm the anger body abrupt release, with to surrounding medium expansion work broken it.Blasting principle is for be filled with explosion by liquid carbon dioxide
In pipe, then being loaded in boring by blasting cartridge, switch on power, liquid carbon dioxide is heated by heated by electrodes element, becomes gaseous state two
Carbonoxide, in making blasting cartridge, gas pressure raises.When gas pressure is more than the shearing stress of blasting cartridge end shear dish, high pressure
Gas is quickly discharged by the valve of blasting cartridge end, provides aerodynamic force and thrust for explosion matter, is collapsed by medium distending.
Using liquid carbon dioxide to destroy medium is that first American's Lang Aier Haddock Adams proposes and attempt,
Start to develop rapidly to the eighties in 20th century, be progressively applied to explosion focus, metallic article molding, underground mine, surface mine
The fields such as exploitation, become a kind of potential Novel explosion equipment.Carbon dioxide blasting technique initially answering in mining
With, it is due to the stable chemical property of carbon dioxide, substitutes explosive blasting, for underground coal mine coal blasting, can effectively control
The generation of explosion spark processed, thus avoid gas, coal-dust explosion；Subsequently, this Technique Popularizing is to the gas in high methane colliery, underground
Explosion guides release, tunnel profile presplitting molding etc., is deeply favored by underground mine.Enter 21 century, domestic carbon dioxide explosion
Equipment manufacturer progressively emerges in large numbers (critical piece still relies on import), and operation strategies is widened further, opens up from underground mine exploitation
Exhibition is exploited to surface mine, crosses non-coal mine from field, colliery, occurs in that the successful example that a lot of non-coal mine uses.When
Before, though carbon dioxide blasting technique is at Application in mining, but its Maturity is not enough, is still in and constantly grows up and developmental stage.
Colliery in exploitation, the recovery method of commonly used underground blasting.Due to, traditional explosive produces in blasting process
Raw substantial amounts of high temperature and flame, therefore, carried out potential safety hazard to colliery mining belt, especially entered in high methane and projecting mine
During row detonation, coal dust very likely with gas explosion.In recent years, in order to improve the safety of coal mining, carbon dioxide
Exploitation is arisen at the historic moment.Carbon dioxide exploitation is with carbon dioxide as explosive source, and carbon dioxide exploitation device is main
Implement the gas-field exploitation mode that device is carried out.Wherein, carbon dioxide exploitation device includes that high intensity fills liquid carbon dioxide metal
Pipe, heater, level pressure let out the parts such as energy device.In carrying out recovery process, one end that carbon dioxide is exploited device is positioned over coal
In body boring, activating heater by exploder, the internal liquid carbon dioxide of heating becomes gas, make volume expansion 600 times,
Pressure reaches the carbon dioxide abrupt release of hundred MPas, thus has reached the requirement of coal blasting.But at carbon dioxide
During instantaneous explosion, stretch into the carbon dioxide exploitation device in coal body boring, can be under the effect of instantaneous explosion power, be exceedingly fast
Speed flies out in boring, is added significantly to the danger of explosion, thus affects and hinder answering of carbon dioxide exploitation
With.
Carbon dioxide blasting cartridge is high due to safety, the most progressively replaces detonator.Owing to having fire when detonator carries out bursting work
Flower, easily causes safety hazards, and explosion thing exists potential safety hazard in storing, transporting and use.Traditional carbon dioxide is quick-fried
Broken pipe is compressed in air accumulator body in spraying due to carbon dioxide, when the pressure in pipe is excessive, can to carbon dioxide blasting cartridge with
And environmental danger around.Therefore, it is highly desirable to the adjustment by structure, to develop a safety carbon dioxide
Blaster.
