Explore the underpass of the coal mining mine at a depth of -350m in the middle of Ha Long

    Nguyễn Hùng |

    Quang Ninh - The underpass of the Nui Beo mine is one of the most modern underpass systems in the Coal industry, tens of kilometers long, located deep underground.

    From the ground, it took more than 1 minute for the elevator to stop at a depth of -350m. A very large underpass system, enough for large trucks to run, appears before the eyes.

    This is a basic furnace road system, running through the sidewalks, so that from here, workers and laborers can continue to open other furnaces to exploit coal.
