Delay Circuit for Multiple Detonator
Blasting is usually the first step in any mining process. Detonators are compact devices that are designed to safely initiate and control the performance of larger explosive charges for blasting. Different kinds of detonators like chemical, mechanical, electrical are available but all of them have several drawbacks and there are various hazards associated with them like accidental initiation due to electrostatic discharge or radio frequency interference, improper firing of the circuit or problem in delay or logic of the circuit. Now-a-days, electronic detonators are being used that eliminate almost every drawback of the earlier inventions.
