दुनिया का सबसे गहरा गड्ढा | Deepest Hole In The World | Kola Superdeep Borehole | Phir Bol Hindi. The Kola Superdeep Borehole is the result of a scientific drilling project of the Soviet Union in the Pechengsky District, on the Kola Peninsula. The project attempted to drill as deep as possible into the Earth's crust. Drilling began on 24 May 1970 using the Uralmash-4E, and later the Uralmash-15000 series drilling rig. Boreholes were drilled by branching from a central hole. The deepest, SG-3, reached 12,262 metres (40,230 ft) in 1989 and still is the deepest artificial point on Earth. 1. दुनिया का सबसे गहरा गड्ढा.    • दुनिया का सबसे गहरा गड्ढा | Deepest Hole I...   2. दुनिया की 7 रहस्यमयी मूर्तियाँ.    • दुनिया की 7 रहस्यमयी मूर्तियाँ | 7 Mysteri...   3. इस गहरे गड्ढे का राज😱    • इस गहरे गड्ढे का राज😱 | The Mystery Of The...   4. दुनिया के 10 सबसे खतरनाक ब्रिज 😱    • दुनिया के 10 सबसे खतरनाक ब्रिज 😱 | 10 most...   5. जलपरी का रहस्य !😱    • जलपरी का रहस्य !😱 | Secret of Mermaid | Ph...   6. 6 एसी जगह जिन पर कोई यकीन नहीं कर रहा    • 6 एसी जगह जिन पर कोई यकीन नहीं कर रहा 😱 | ...   7. मिस्र के पिरामिड का रहस्य !    • Видео   8. धरती से 5 सेकंड ऑक्सीजन गायब हो जाए?    • धरती से 5 सेकंड ऑक्सीजन गायब हो जाए |Oxyge...   9. क्या पृथ्वी से खत्म हो जाएंगे पुरुष?    • क्या पृथ्वी से खत्म हो जाएंगे पुरुष? | Wil...   10. यति " हिममानव " का रहस्य !    • यति " हिममानव " का रहस्य ! | Mystery of th...   Thanks for Watching Phir Bol Hindi Owner :- Rakesh All the Information given in the video is taken from Google, Youtube, Wikipedia, Books and trusted website.
