Expanding the exploitation of the Coc Sau - Deo Nai coal mine after the merger with 2,075 billion VND
Quang Ninh - The Coc Sau - Deo Nai Mining Cluster Exploitation Project not only contributes to ensuring energy security, but also stabilizes the work of thousands of workers.
Deo Nai - Coc Sau Coal Joint Stock Company, under the Vietnam National Coal - Mineral Industries Group (TKV), is continuing to complete procedures to apply for a License for the Coc Sau - Deo Nai Mineral Cluster Exploitation Project.
This is one of the key investment projects strategically oriented for development after the merger between Deo Nai Coal Joint Stock Company and Coc Sau Coal Joint Stock Company into Deo Nai - Coc Sau Coal Joint Stock Company in mid-2024.
The total investment of the project is 2,075 billion VND, the exploitation capacity is 2.7 million tons of coal/year and the project implementation period is 15 years (expected to end exploitation in 2039).
According to the report of Deo Nai - Coc Sau Coal Joint Stock Company, in 2024, it has completed the selection of contractors for 10 packages of the project and strived to complete the equipment investment packages in the approved 2025 construction investment plan.
Previously, to prepare for the merger between Deo Nai Coal Joint Stock Company and Coc Sau Coal Joint Stock Company, the People's Committee of Cam Pha City approved the 1/500 scale Detailed Planning for the Coc Sau - Deo Nai Mining Cluster Exploitation Project located over 11 communes and wards of Cam Pha City, Quang Ninh Province.
This open-pit mine cluster project is about 1,790 hectares wide, with a life of 15 years, expected to start from 2025, with raw coal reserves of over 31 million tons, maximum exploitation capacity of 2.7 million tons/year.

Regarding open-pit mining, it is expected to combine two existing mounds of Deo Nai mine and Coc Sau mine; then expand the mine area to the Southwest for exploitation after 2029.
The height of the exploited moong bottom is -345m (currently the deepest level in Vietnam, at -300m). The largest dumping height is +295m, especially for areas with the current terrain reaching the elevation of +300m, the status quo will be maintained and the environment will be restored.
To exploit this mine cluster, in addition to promoting existing infrastructure and equipment, more advanced equipment will be invested in to exploit coal resources, contributing to the stability and ensuring national energy security, creating jobs for thousands of direct workers.
According to the report of Deo Nai - Coc Sau Coal Joint Stock Company, after 6 months of the merged company coming into operation, there are still many difficulties, especially at the Coc Sau coal mine. The exploitation conditions are getting deeper, the high height of the lifting load affects the progress, the large amount of sludge affects the treatment, the high cost makes it difficult to access coal.
Currently, the total number of officers, workers and laborers of the company is more than 3,500 people, with an average salary of 13.823 million VND/person/month, an increase of 108.2% compared to the plan.
