Super Coal Delay Detonators

SUPER COAL DELAY DETONATORS (CDD)

 

Super Coal Delay Detonators are non-incendive in nature and have delay numbers zero to six (0 - 6) with a nominal time interval of 25 milliseconds between each successive delay number. The delay numbers are displayed on tags on the leg wire. Electrical Fuse Heads are fitted to the Copper filled shells. Precise consistency of the Fuse Head is maintained by a fully automated process. With Super Coal delay detonators, all the shots can be connected in one series and fired in one round with a desired delay arrangement.

Super Coal Delay Detonators has the approval of DIRECTOR GENERAL MINES SAFETY for use in Degree I/II gassy mines/seams. They can be used for all types of blasting in underground gassy mines.

Packing:

The Detonators are bound in bundles of 25 each. Such bundles (25Nos.) are Packed in wrapper (parcel)40 of these parcels (containing totally 1,000 detonators of 3 meters wire) are packed in a Fibre Board case. Depending on the length of leg wire requisite number of packets are packed in fibre case inside with water- proof paper. Case marking provide for indicating wire length, type of wire and delay number. Higher lengths of leg wire are supplied at customers requirement.


Applications:

Super Coal Detonators are used in Underground gassy mines.
