Abstract
The present invention provides a kind of improvised explosive priming devices, it is formed including short primacord, paraffin, electrical adhesive tape, doubling primacord and Nonel detonator, it is characterized in that common primacord is cut into short primacord, short primacord both ends notch is sealed with paraffin, by short primacord doubling, with electrician's immobilization with adhesive tape doubling primacord, finally Nonel detonator is fixed on doubling primacord, forms improvised explosive priming device.It is intended to improve initiating ability, reduces blasting cost, guarantee demolition effect.The invention belongs to blasting technique fields.
Description
Technical field
The present invention relates to a kind of initiating equipments of bursting work personnel production, belong to blasting technique field.
Background technique
Commercial explosive is widely used in mining, and commercial explosive has the sensitivity to initiation and stability of appropriateness, research shows that
Detonation can be higher, and explosive is easier to detonate and can discharge more energy.Current mining commercial explosive be mostly powder ammonium nitrate explosive,
Powdery emulsifying explosive and emulsion, it is mostly No. 8 detonators that metal mine, which plays explosion medicine detonator used, but is risen using No. 8 detonators
Initiating ability is low when quick-fried powdery emulsifying explosive, need to be by the smooth detonating charge of igniting primer ability.Due to existing igniting primer
Higher cost need to be purchased specially, and bursting work personnel is caused often to use No. 2 rock explosive powder sticks and No. 8 detonator field fabrication letters
Easy igniting primer, instead of the igniting primer of purchase.It is smaller to make simple igniting primer difficulty, but No. 2 rock explosive powder sticks
It need to individually buy, higher cost.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, a kind of improvised explosive priming device is provided, to mention
High initiating ability reduces blasting cost, guarantees demolition effect.
To solve the above-mentioned problems, the present invention provides the following technical solutions:
Improvised explosive priming device, including be made of short primacord, paraffin, electrical adhesive tape, doubling primacord and Nonel detonator,
It is characterized in that common primacord is cut into short primacord, short primacord both ends notch is sealed with paraffin, by short primacord pair
Folding, with electrician's immobilization with adhesive tape doubling primacord, Nonel detonator is fixed on doubling primacord.
The short primacord, for the primacord of the 30cm long formed after common long primacord cutting；
The paraffin is liquid paraffin；
The electrical adhesive tape is the electrical adhesive tape of width 1.8mm；
The doubling primacord, for the short primacord after the doubling of electrician's immobilization with adhesive tape；
The Nonel detonator is No. 8 Nonel detonators.
The present invention utilizes blasting cap initiation doubling primacord, forms detonation medical instrument.The priming device is easy to make, safe, at
This is cheap, not only can guarantee Detonation Initiation Effect, also reduces blasting cost.
Detailed description of the invention
Fig. 1 is short primacord.
Fig. 2 is the primacord after doubling.
Fig. 3 is Nonel detonator.
Fig. 4 is improvised explosive priming device installation diagram.
Wherein: the short primacord of 1-, 2- paraffin, 3- electrical adhesive tape, 4- doubling primacord, 5- Nonel detonator.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
Improvised explosive priming device, including by short primacord 1, paraffin 2, electrical adhesive tape 3, doubling primacord 4 and detonator
Detonator 5 forms, it is characterised in that and common primacord is cut into short primacord 1, seals short 1 both ends notch of primacord with paraffin 2,
Nonel detonator 5 is fixed on doubling with electrical adhesive tape 3 with the fixed doubling primacord 4 of electrical adhesive tape 3 by short 1 doubling of primacord
On primacord 4.
Primacord is cut into the short primacord 1 of about 30 cm length, is used in combination in ground priming system production room referring to Fig. 1
Paraffin 2 is waxed in short 1 both ends incision of primacord and is closed.
Referring to Fig. 2, bursting work scene uses after short 1 doubling of primacord near 1 fold position of primacord and waxing end
For electrician's glue 3 with binding, binding length is 2.5 mm, the doubling primacord 4 of 15 cm of production growth.
Referring to Fig. 3 and Fig. 4, No. 8 Nonel detonators 5 are fixed on doubling primacord 1 with electrical adhesive tape 3.Fixed form
It is fixed on for Nonel detonator 5 close to primacord fold position, the tail portion of Nonel detonator 5 is towards waxing end.
The principle of the present invention is that initiating ability is limited when due to No. 8 blasting cap initiation powdery emulsifying explosives, in order to improve detonation
Explosion priming device is collectively formed in No. 8 detonators and short primacord by the detonation energy of explosive, is substantially increased detonation energy, is made explosive
It is easier to more energy of detonating and discharge.
Primacord used in the present invention, paraffin, electrical adhesive tape and No. 8 Nonel detonators are that equipment, this hair are often used in mine
Bright not only low in cost, the fuse arming test experiment initiation ability after explosion is big, and assembles convenient for bursting work personnel on site, can drop significantly
The blasting cost in low mine.
