- Deo Nai Coc Sau TKV Coal Joint Stock Company is a Vietnam-based mining and energy enterprise primarily engaged in the open-cast exploration, extraction, processing, and commercial distribution of anthracite coal. Operating as a consolidated operating subsidiary of the state-owned Vietnam National Coal - Mineral Industries Holding Corporation Limited (Vinacomin), the company manages extensive open-pit mining concessions across the Cam Pha coal basin in Quang Ninh Province, Vietnam. The enterprise traces its corporate and industrial origins to the establishment of the Deo Nai and Coc Sau state mining enterprises in 1960 and maintains its corporate headquarters in Cam Pha City, Quang Ninh Province, Vietnam.
The company structures its operations across three primary business divisions: Coal Extraction and Processing, Mechanical Engineering and Equipment Maintenance, and Logistics and Mining Support Services. The company provides a comprehensive range of products and industrial services, including: commercial anthracite coal products across multiple standard grades, including lump coal, sized coal, fine coal, blended coal, and pulverized dust coal tailored for thermal power generation plants, metallurgical steel works, cement production facilities, chemical and fertilizer manufacturers, and regional export markets; coal preparation services, including washing, crushing, screening, sorting, and standardized calorie blending; mechanical fabrication, overhaul, parts manufacturing, and technical maintenance for heavy mining machinery, high-capacity excavators, drilling units, and heavy-duty off-highway haul trucks; civil engineering and mine development services, encompassing overburden stripping, pit excavation, drilling and blasting operations, roadway construction, and mine drainage infrastructure management; and domestic freight transportation, port handling, barge loading, and bulk mineral logistics.
In recent corporate developments, the enterprise completed a landmark corporate merger uniting Deo Nai Coal Joint Stock Company - Vinacomin and Coc Sau Coal Joint Stock Company - Vinacomin into a single unified legal entity named Deo Nai Coc Sau TKV Coal Joint Stock Company, trading under the ticker symbol TD6 on the Hanoi Stock Exchange. This strategic combination was executed under Vinacomin's corporate restructuring master plan to consolidate contiguous mining perimeters, eliminate boundary coal reserve losses, integrate shared dumping sites, streamline administrative overhead, and pool heavy equipment fleets across the shared geological deposit. Following the merger, the company has focused on optimizing deep-pit open-cast exploitation, deploying centralized fleet dispatch and digital mine management technologies, implementing environmental land rehabilitation and slope stability monitoring initiatives, and executing operational synergies to lower production costs and sustain mining output in the Quang Ninh coal region.
