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.

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

TECHNOLOGY

FROM

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.

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
