2. Rock Excavation Drill & Blast Control Blast
Mechanical excavation - Hydraulic breaker; jackhammer; Road header
Hydraulic / pneumatic Splitter
Chemical
What Next?

3. Rock Excavation Drill & 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.

4. Rock Excavation Control Blasting
Volume excavation difficult to achieve
Permission & license is must for usage, storage & transportation
Limited permission available for usage, when its must
Usage is still restricted like drill & blast

5. Rock Excavation Reasonable price
Mechanical Excavation - Hydraulic Breaker; Jack Hammer; Road Headers etc.
Reasonable price
Volume excavation not possible or very time consuming in hard rock
Very High Noise for rock breaking
Easy to get services as many agencies available

6. Rock Excavation Rock Splitter Expensive Technology
Volume excavation not possible
Easy to use in confined space like trenches, Vertical Shaft, Tunnel corners etc.
Easy to get services as many agencies available

7. Rock Excavation Chemical Process
Effective when boulders or rock is open from all the sides
Volume excavation not possible
Easy to use
Not effective in hard & compressed rock

8. ROCK EXCAVATION
Any Other Solution ?

9. SOLUTION ECO FRIENDLY PULSE PLASMA ROCK FRAGEMNTATION TECHNOLOGY
FROM
KAPRA, S. KOREA

10. Pulse Plasma Concept

11. PRINICIPAL EPI 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.

12. PRODUCT Electro Power Impactor (EPI): Impact Cells:
Input Power – 30 KVA, 380 V, 3 phase, 50 Hz
Storage Energy – kJ
Output Energy – 1, 34, 680 Kw
Impact Cells:
2Al + 3Cuo = Al2O3 + 3Cu KJ
Plasma Cells & EPI are patented worldwide including US, Europe, Japan, Australia, Korea etc

13. PROCESS Drill holes of 51 mm to a depth of 3 meter Insert Plasma cells
Plug the hole using seal & sand bags
Energized Electro Power Impactor (EPI) using 30 KVA Generator.
Provide Pulse to Plasma Cells from EPI
Remove the Fragmented Rock using normal Excavator

14. ADVANTAGES
Non-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.

Resonance
Vibration Frequency is 10–30 Hz
VIBRATION Frequency is Hz
General Building vibration Frequency 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
