DTH detonators are developed to provide accurate down the hole-delay in the blast. It consists of a shock tube of required length, with delay detonator and a suitable connector. In order to arrest the ingress of water, the connector end is sealed. The other end of the tube is crimped to a delay detonator with a suitable plug. Application These are used for surface blasting, quarrying and long hole-blasting. Advantages 1. True bottom initiation is achieved2. Ground vibration is controlled3. Air blast noise is minimized4. Good fragmentation5. As the explosive shock wave is confined, there is no desensitization of explosives. This results in higher explosive efficiency.6. Risk of accidental initiation due to stray current, static charges and radio frequency signals is ruled out.
