Components of Blasting:

1. Cartridges: The explosive material comes in cylindrical shape in which blasting materials are filled which are wrapped in plastic and hence are called cartridges. They come in various sizes which depends upon blasting area radius.
2. Down to Hole (DTH): These are electronic wires which are connected with cartridges.
3. Trunk Line Delay Detonators (TLD): These are wires which are connected with the different DTH’s.
4. Electronic Detonators: These detonators are supposed act as an initiator in blasting where they
5. Wires: These are electric wires which are used to connect with detonators and allows blasters move to a safe distance before connection with Exploders.
6. Exploders: Exploders are called batteries which is used to initiate the command of blasting.

They are machines which has a leaver and a single button. The leaver is rotated on a 360 degrees to charge the machine and once the machine is charged the button is pressed and the blasting takes place.

Process of Blasting:

For a blasting operation, blasting areas are identified and the blasters do a certain amount of holes on these areas by the help of crawlers and then fill them with explosive materials. After filling the holes with explosive materials these materials are joined with DTH’s. These different DTH’s are joined with TLD’s. After appropriate connection they are connected with the Electronic Detonator and the detonator is connected with electronic wire. By the help of the electronic wire blasters move to a far of distance and then the blaster connect the wire with exploder. After appropriate connection, the exploder is charged and the button on exploder is pressed and the operation takes place.
