In the first 10 months of 2025, Nui Beo Coal Joint Stock Company, under the Vietnam National Coal - Mineral Industries Group (TKV), exploited 1.65 million tons of raw coal. According to the company representative, with this momentum, the company's coal output for the whole year of 2025 will reach 2 million tons - the first time reaching the designed capacity of 2 million tons/year of the mine.
Nui Beo Coal Joint Stock Company used to be one of TKV's largest open-pit coal mining units, with the peak in 2009 becoming the first unit in the coal industry to exploit 5.1 million tons of raw coal/year.
However, the company quickly switched from open-pit exploitation to tunnel exploitation when the reserve of open-pit resources decreased sharply. In 2012, the Nui Beo Coal mine tunnel construction investment project, with a capacity of 2 million tons/year and a total investment of 5,300 billion VND, was officially started.
In early May 2017, the market with a designed capacity of 250,000 tons of coal/year, constructed by the self-constructed Company, officially exploited the first ton of underground coal.
At the end of 2021, the project completed the basic construction process. This is also the year that Nui Beo Coal has completely ended the exploitation of open-pit coal, closed the mine and switched to exploitation completely under the mine.
In November 2021, this coal mine welcomed the 1 millionth ton of underground coal of the 2021 plan year.
The output of underground coal mining has increased gradually every year, reaching 1.63 million tons of raw coal in 2024, ensuring jobs for more than 3,000 people.
It is expected that by December 25, 2025, this coal mine will officially reach a designed capacity of 2 million tons of coal/year.
Currently, the company is investing in completing a light-class mechanical system and speeding up the excavation progress to -500m to ensure stable output for many years to come. At this level, Nui Beo coal mine has become the deepest underground coal mine in Quang Ninh.
