Eco Friendly Pulse Plasma Rock Fragmentation Technology From KAPRA, South Korea

1. Eco Friendly Pulse Plasma Rock Fragmentation Technology From KAPRA, South Korea Technology Brought to you by: Dattatreya Inc., Vadodara

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 • 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 ROCKFRAGEMNTATION TECHNOLOGY FROM KAPRA, S. KOREA

10. Pulse Plasma Concept GENERATOR EPI PULSE PULSE GENERATOR CELL CELL

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): • 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

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.

15. Comparison Table of Noise / Vibration Vibration Level Comparison Sound 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.
