 WABOCORD (DETONATING CORD)

Wabocord consist of a core of high explosive contained in polythene and wrapped in various layers of cottons /jute yarn. The detonating cord is then coated with PVC , giving it a high tensile strength and making it water proof . the structure of Wabocord assures its efficient field performance as it is unaffected by both heat and cold within a wide range from - 60 °C to 30 °C 

TECHNICAL DATA     Wabocord

Velocity of detonation 6000-7000 m/sec 
Water resistance   Water proof ,canWithstand pressure of 25 meters water head for 48 hours.
Explosive grammage  10 + 1 g/m

 

 

DETONATOR

 SEISMIC DETONATOR 

Seismic Detonators are specially formulated, high density, high energy detonators for sensitive seismic explosives. Designed exclusively to meet the rigid requirements and environmental extremes associated with geophysical exploration. Offering moderate velocity and extraordinarily low gas production, they improved seismic energy across usable bandwidth for superior final data as well as improved signal-to-noise ratio.

External Dia 7.0 - 7.2 mm
Wire length 3, 4.5, 12, 24 and 30 meter

Blasting Accessories:

wnMilli second (MS) and half second (HS) electric delay detonators are meant to effect delayed blasting action in multi row bench blasting and tunneling. This action greatly improves blasting results as better fragmentation and this action greatly improves blasting fragmentation and ground vibration control is achieved. For surface blasting only, MS delays are used while in underground blasting, a combination of both MS and HS detonators is employed.
