Rock Blasting  

KAPRA is research laboratory based at South Korea & invented rock fragentation technology using high power pulse for mili second called Plamsa. The procss involved normal DG set to charge Electro Power Impactor (EPI). EPI released stored energy in Cell e,baded in rock. The cell are made up of Aluminium powder & cuper oxide powder. Cells are supplied prewired. 5 to 7 cells are connected in serise with EPI & energise through switch. Thus electrothermic reaction generates high heat & release the energy to fractured rock. There is no Gas & zero Shock wave. Vibration velocity & sound level during rock fragmentation is well within limit. Thus it is safe to use near neay construction area. The Plasma Technology is Non Explosive worldwide.
