The invention belongs to blasting technique field, is related to a kind of measuring method of explosive detonation pressure, refers in particular to one kind and exists
The method of explosive detonation pressure in the actual blasthole of demolition site direct measurement.
Background technology
Explosive detonation pressure is referred to as：Detonation pressure is the important parameter in explosive, explosion effect research, blasting engineering.It is so far
Only, the method that many measurement explosive detonation pressure have been developed in people, is roughly divided into direct measurement and relatively measures two indirectly
Class method.One of explosive detonation pressure typical method measured directly, it is the pressure sensor such as directly embedded copper-manganese piece in explosive
[Xiong Changyan, electromagnetic method and pressure drag method measure the exploration [J] of detonation pressure, blast and impact, 1984,4 (3) to pressure drag method simultaneously:79-
81.], measure explosive detonation pressure by the resistance variations of circuit measuring piezoresistive sheet.Another direct measuring method of detonation pressure
It is electromagnetic method[1], explosive is placed in the magnetic field of fixed field strength, Laplace particle velocity meter is buried wherein, in explosive detonation speed per hour
Degree meter moves together with detonation gas, and speedometer cutting magnetic line produces electric signal and records detonation gas movement velocity, can root
Explosive detonation pressure is calculated according to surveyed detonation gas speed.Directly embedded fiber grating is measured with laser interference also in explosive
Research [Wei Lin, explosive detonation pressure test technical research [D], the Northcentral University Master's thesis tutor of detonation pressure：Wang Gao, 2012.].
The advantages of above several method is that detonation pressure, reliable test result can be obtained with direct measurement.But the piezoresistive sheet of pressure drag method is very
Piezoresistive sheet easily can be destroyed quickly by the local microjet and focus in explosive damage, especially powder type explosive and grain powder,
So that pressure drag method is difficult to measure granular and powder type explosive detonation pressure.Electromagnetism rule is that the magnetic of fixation must be set outside explosive
, measurement apparatus is complicated, is generally also only intended to test of the military explosive in laboratory.Although fiber grating laser interference is surveyed
Examination is a kind of very promising method, but technology is still immature at present.The side of explosive detonation pressure in also a kind of direct measurement blasthole
Method is that a kind of piezoeletric quartz sensor of tourmaline [Liao Xiankui etc., aqueous explosion velocity of explosive and relative in deep hole are placed in explosive
The on-the-spot test research [J] of detonation pressure, engineering explosion, 1999,5 (3):6-10.], this method has two shortcomings, one is electrically
The validity of measurement result of the piezoeletric quartz sensors such as stone under 1.0~10.0GPa detonation pressure magnitude；The second is every time
Experiment can all demolish the expensive piezoeletric quartz sensor of consumption, and testing cost is very high.
The measuring method of the indirect comparison of explosive detonation pressure is a lot, and its general principle is all based on impedance match method, will
Explosive, which is placed in contrast medium, to be ignited, particle speed after the shock velocity or ripple that are passed to by measuring detonation in contrast medium
Spend to try to achieve explosive detonation pressure.This method often by be divided into using contrast medium difference：Lucite method [Zeng Guiyu, tall and big member
Deng, the detonation pressure [J] of lucite method test nitrolite, war industry's journal, 2009,30 (5):541-545.], adopting water tank method [Xue Peng
Longevity, Wang Shuping, the research [J] of big dose adopting water tank method measure explosive detonation pressure, explosive wastewater, 1992, (2)：10-19.], diiodo-
Methane method [Yu Deyang, to a kind of new detonation pressure method of testing-diiodomethane method-research [J], blast and impact, 1985,5
(2):69-72.], air method [Fu Zhirong, Chen Yongfu, utilize air shock wave method measurement commercial explosive detonation pressure [J], mining and metallurgy work
Journey, 1984,4 (3)：1-8.] etc.；It is divided into measurement velocity of wave, freedom by measured position in contrast medium and parameter difference
Face particle velocity and explosive and contrast medium boundary face velocity；Used means of testing is mostly high-speed photography, light probe, laser
Interference is tested the speed, electric probe etc..Such as：The transparent mediums such as lucite method, adopting water tank method, diiodomethane method, air method can make
With High frequency photographing measurement shock wave, equally electric probe can also be used [Zheng Feng etc., commercial explosive to be determined with the water tank electrical resistivity survey skill of handling needles
Detonation pressure [J], safety of coal mines, 2003,34 (6):The 40-42. Huang third of the twelve Earthly Branches gives birth to etc., and it is quick-fried to determine commercial explosive with sulphur block electric probe
Hong pressure [J], explosive, 1994,32 (6):1-4.] or a kind of light probe measurement [Yu Deyang, to new detonation pressure test side
Method-diiodomethane method-research [J], blast and impact, 1985,5 (2):69-72.] shock velocity.Also useful laser position
Move method [Huang Wenbin etc., the TA01 explosive Measurement of detonation pressure of the determination detonation pressure of interference rate meter DISAR measure interface particle velocities
[C], energetic material in 2014 and Desensitive ammunition technology science conference Papers collection, 2014：488-489.].Therefore impedance
Matching method has no too big limitation to used contrast medium, and the acoustic impedance of contrast medium is measured closer to explosive in theory
Detonation pressure it is more accurate；Furthermore the property of used contrast medium is determined by used method of testing, such as：Flash spotting DISAR,
High-speed photography need to use transparent medium etc..The advantages of impedance match method is applied widely, and adoptable means of testing is also more,
But most test system is all complex, so current Measurement of detonation pressure technology almost all is for fried in laboratory
Medicine performance study.
It is well known that the detonation of many explosives is in nonideality, especially industrial mixed explosive, even explosive
After the explosive Fabrication parameter such as composition, mixing uniformity, granularity has determined, its detonation property is still close by size of powder charge, filling
Degree, humidity, temperature, environmental pressure, ground experiment room in small medicine very big by the influence of the external environment conditions such as explosion physical property matter
The detonation test result of amount, which is directly used in actual blasting engineering, often has very big error.And current accurate blasting engineering
Design is badly in need of determining detonation property of the explosive under Practical Project use condition with quality control, therefore, invention one
Kind directly measures explosive detonation pressure at the scene method in blasthole hole, to solve Practical Project demand.

Resistivity is processed into length x and time t relation, obtains the curve such as Fig. 3.Have that Fig. 3 is visible, half section of a left side for curve is explosive cavity
(5) the detonation wave geometric locus of explosive in, right half section of geometric locus for shock wave in contrast medium (4) paraffin.By right half section
Paraffin shock wave track is visible, and bending is had occurred and that after 50~60mm of shock motion, about 0.5 times of diameter with theoretical value
I.e. radius is consistent.In addition, the initiating terminal of left half section of explosive detonation ripple geometric locus has some unstable due to voltage suddenly change
Fluctuation.Therefore the fluctuation the initial segment of detonation wave recording curve is omitted, and take the straightway 50mm of paraffin shock wave track to grow, again
Drafting pattern 4, and fitting a straight line is carried out to detonation wave and shock wave respectively using least square method, obtain following linear equation：
Explosive detonation ripple：X=3.5519t+92.0882 coefficients of determination R2=0.9990
Paraffin shock wave：X=3.5958t+94.1407 coefficients of determination R2=0.9985
Obviously, the slope above in linear equation is detonation wave velocity and paraffin shock velocity, after retaining decimal point
Three decimals, can be obtained：
Explosive detonation wave velocity:D=3.552mm/ μ s
Paraffin shock velocity:DW=3.596mm/ μ s
By density pW0=0.88g/cm3The shock adiabatic curve of paraffin, i.e. Hugoniot relations scope of application uW=0.3~
2.6mm/μs：
DW=-0.307uW 2+2.772uW+1.518
By paraffin shock velocity DWSubstitute into and solve One- place 2-th Order algebraic equation, obtain particle velocity u after paraffin shock waveW
Two solution 0.825 and 8.204, omit irrational 8.204, obtain shock wave particle velocity uW=0.825mm/ μ s.According to
Shock wave pressure calculation formula：
PW=ρW0DWuW
Shock wave pressure P in paraffinW=0.88 × 3.596 × 0.825=2.611GPa.
According still further to the theoretical formula of impedance match method[8,9], explosive detonation pressure P can be calculatedH：
PH=PW(ρ0D+ρW0DW)/(2ρW0DW)
PH=2.611 × (0.729 × 3.552+0.88 × 3.596)/(2 × 0.88 × 3.596)=2.374GPa
Can also be according to detonation pressure formula PH=ρ0D2/ (K+1), obtain explosive polytropic index K=2.874.Finally, by explosive
Test result arrange such as following table：
