Abstract: 

Since the invention of gunpowder in 1860 by Alfred Nobel mining industry was always in need of initiating devices which helps in increasing blast size, improve safety during charging & blasting operation, as well as explosive performance. From plain detonators & Safety fuse system to Shock-tube initiation system, commercial basting has helped the above cause. However, each system has some limitation regarding the accuracy of delay, safety requirement as well as complexity required regarding blast requirement of the modern mining industry. Electronic Delay Detonators have come a long way since their invention in the late 90s. They have helped blasting engineers in solving modern mining requirement of the massive blast with minimum vibration, better control on fragmentation, blasting multi-layer rock together, controlling throw & back break etc. Electronic Delay Detonators have been introduced in the Indian market mainly for Vibration controls. With increased knowledge, Indian mining industry is now ready to embrace the other technological benefits of Electronic detonators. This paper is an attempt to review the use and benefits associated with the use of Electronic detonators, evolution and future growth prospects of the same in Indian mining industry
