CHAIN OF DETONATION
INTRODUCTION:-
KISI BHI BOMB YA CHARGE KO
FIRE KARNE KE LIYE EK
SILSILEWAR (CHAIN KI TARTIB
KI JARURAT HOTI HAI TAKI
HADSON SE BACHA JHA
SAKEN. IS CHAIN KO CHAIN
OF DETONATION YA
/EXPLOSIVE FIRING TRAIN BHI
KAHTE HAIN.

3. Is prakriya me sabse pahle flame
producer aata hain jo ki aag paida karta hai.
Us aag ko aage le jane ka kam flame carrier
dwara kia jata hai.Flame carrier aag ko
detonator tak pahuchata hai, detonator aag ko
dhamake me badli karta hai, us dhamake ko
aage le jane ka kam detanotion wave carrier
dwara kiya jata hai, jo ki dhamake ko booster
tak pahuchata hai booster ko dhamaka milne
par chhota sa dhamaka ( small explosion )
hota hai. Jis se main charge ko sufficient heat
aur energy mil jati hai aur wah explode ho jata
hai.
CHAIN OF DETONATION

4. DEFINATION:- Aag paida karne se lekar main charge ko
fatne tak ke bich me jo kram vadh (sequence) mein jis
accessories ko istamal kiya jata hai ushe chain of
detonation kahete hai.

jariye ham aag paida kar sakte hai..
(i) Safety Matches
(ii) Fuze Matches
(iii) ISF Striking (Igniter Safety Fuze Striking)
(iv) ISF Electric (Igniter Safety Fuze Electric)
(v)Switches - Switch No 4 Pull Mk I,

Switch No 6 Release Mk I,
Switch No 10 Time Pencil.
CHAIN OF DETONATION

7. (b) Flame Carrier:- yah aag ko aage le jane ka
kam karta hai aur aag ko detonator tak
pahuchata hai. Zarurat parne par delay ka
bhi kam karta hai. Yeh hamen do quism ka
milta hai
Safety Fuze No 11 Mk II.
Orange Fuze.
CHAIN OF DETONATION

8. (c) Conversion of Flame to Detonation
Wave (Detonators):-Yeh flame carrier se
mili aag ko detonation (dhamaka) mein
badli karta hai. Jo ki charge ko fire karne ke
liye sabse mahatwapurna hai.
(i) No 27 Detonator.
(ii) No 33 Electric Detonator.
(iiii) No 06, No 08, No 103, No 108 and
Commercial Detonator.
CHAIN OF DETONATION

9. (d) Detonation Wave Carrier:-Dhamaka ki lehar
(shock wave) ko charge tak le jane ka kam karta
hai. Yah kam karne keliye detonating cord ka
istemal kiya jata hai. Iski VOD 6000 to 8000 mtrs/s
hoti hai
Detonating Cord (Prima cord, Cordtex,
Nova Cord)
CHAIN OF DETONATION

10. (e) Booster:- Iska istamal dhamaka ko bhadhane ke
liye kiya jata hai taki main charge ko jarurat shuda
garmi aur urja (heat & energy mil jaye. Yeh do
quism ka milta hai.
(i) GC Primer
(ii) CE Primer (Tetryl based)
(iii) CE PELLET
CHAIN OF DETONATION

11. (f) Main Charge:- Target ko udhane ke liye jis
explosive ka istemal karte hain use main charge
kahte hain. Is ko kitni matra mein lagaya jaye
tatha kis shakal mein design kiya jaye yah target
ke upper nirbhar karta hai. Fauz mein milne wala
explosive is prakar hai.

CHAIN OF DETONATION

12. SAFETY FUZE KO TAIYAR KARNE KA TARIKA
1)Safety fuze ke coil se 30cm ka tukra kat
kar phenk do .
2)30 cm ka dusara tukra kat kar jalne ki raftar
check karo.
3)Agar jalne ki raftar 27 se 30 sec tak hai to
is fuze ko istemal kar sakte hai varna isko
istemal mat karo.
4)Matches se aag deni hai to safety fuze ka
ek sira tircha kato aur agar ISF istemal kar
rahe hai to do sira golai mein kato.

13. DETONATOR KO TAIYAR KARNE KA TARIKA
1)Detonator ke khule sire ko anguthe ke nakhun
par thok kar saf karo.
2)Koi bhi ek tinka lo aur detonator ke andar ki
gaharai napo.
3)Mili hui gahrai se 1 mm kam duri par safety
fuze par ek nishan lagao.
4)Safety fuze ko detonator ke andar dakhil karo
5)Crimper ki madad se detonator ke khule sire ki
taraf ek crimp karo. Bana hua initiation set
shole ko dhamake me badal kar chain of
detonation suru karne ke liye istemal karte
hain.

14. Set of Initiation (Priming):- ye 3 prakar ka hota hain

(a) (I) Set No 1 - Safety fuze with detonator

18. Safety Precautions while Preparing Set of Initiation.
(a) Priming hole ke andar detonator ko jabardasti
nahi dalna. Wooden rectifier ka istemal karo.
(b) Non sparking tools ka istemal priming hole mein
karo.
(c) Low explosive Ko detonator se initiate mat karo.

19. FAUJI BARUD KO FIRE KARNE
KE TARIQUE
1 Barud mein sidha detonator
(initiation set) dalkar
2. Barud ke andar se cordtex
guzarkar ek thumb knot lagakar
3. Barud ke upar cordtex ke tin
chakkar aur ek half clove hitch
lakar..

20. INITIATION SET FAIL HONE KE
KARAN
1)Nami ka asar.
2)Detonator ka safety fuze se thik
milap na hona
3)Galat crimp ka hona
4)Safety fuze ko galat tarika se
katna.
5)Safety fuze mein tez mor hona
