Rock ExcavationDrill & Blast
Cheapest Volume excavation possible Permission & license is must for usage,
storage & transportation Not permitted in the city, critical &
sensitive areas like airport; Dock, Refinery & Petrochemical complex, Existing infrastructure, Near to Oil & gas pipe line; Near to Railway lines; Heritage structure etc.
Rock Excavation
Control BlastingVolume excavation difficult to achievePermission & license is must for usage,
storage & transportationLimited permission available for usage,
when its mustUsage is still restricted like drill &
blast
Rock ExcavationMechanical Excavation - Hydraulic
Breaker; Jack Hammer; Road Headers etc.Reasonable priceVolume excavation not possible or very
time consuming in hard rockVery High Noise for rock breakingEasy to get services as many agencies
available
Rock Excavation
Rock SplitterExpensive TechnologyVolume excavation not possibleEasy to use in confined space like
trenches, Vertical Shaft, Tunnel corners etc.
Easy to get services as many agencies available
Rock ExcavationChemical Process
Effective when boulders or rock is open from all the sides
Volume excavation not possibleEasy to useNot effective in hard & compressed
rock

KAPRA, S. KOREA
Pulse Plasma Concept
PRINICIPALEPI Plasma is a Thermal Process.Aluminum & Copper Oxide powder is energized in milliseconds to a Plasma stage using Electrostatic Power Impulse (EPI) Generator.
Process generates the heat & impact wave to crack & break the rock.
PRODUCTElectro Power Impactor (EPI):
Input Power – 30 KVA, 380 V, 3 phase, 50 Hz Storage Energy – 268.92 kJ Output Energy – 1, 34, 680 Kw
Impact Cells: 2Al + 3Cuo = Al2O3 + 3Cu + 1197 KJ
Plasma Cells & EPI are patented worldwide including US, Europe, Japan, Australia, Korea etc
PROCESSDrill holes of 51 mm to a depth of 3 meterInsert Plasma cells Plug the hole using seal & sand bagsEnergized Electro Power Impactor (EPI)
using 30 KVA Generator.Provide Pulse to Plasma Cells from EPIRemove the Fragmented Rock using normal
Excavator
ADVANTAGESNon-Explosive Product & Process certified by
Petroleum & Explosive Safety Organization, Government of India.
No License & Permission for usage, storage & Transportation for Plasma cells & EPI.
Low Vibrations; Low noise & Low Dust.No Flying of Rocks & No Gases / fumes.No Resonance Generated & hence safe to use
near to any existing structure.

Vibration Level Comparison
The difference of 10 dB means about 10 times difference in real sound i.e. The difference
of 80 dB and 70 dB is 10 times, and that of 80 dB and 60 dB is about 100 Times louder.

Ammonia (Any) Nitrate =Water + gas+ gas+ Energy
Solid = Solid + Solid + Energy
Energy fm Gases creates more impact
Energy 20% Shock Wave + 80% Gas Pressure

Gas Generation
980 Liter / Kg None
Energy Generates noise, Vibration & pressure
Generates Impact Pulse Wave
Rapid gas Exp. - Earth Vibration slowly
reduced & at long propagation distance
Being thermic reaction vibration reduced speedy &
disappeared rapidly

Resonance Vibration Frequency is 10–
30 Hz
VIBRATION Frequency is
50-120 Hz
General Building vibration Frequency 15-20 Hz
Due to overlapping of frequency resonance
generated & effect the nearby structure
As frequency is not overlapping, it does not generate
resonance
EPI is safe to operate to nearby structure
Storage Required specified secured & safe

Usage License required No license required
Transportation License & special vehicle required
No need for license & special
permission
