Another underground mining project of the coal industry up to -300m deep

Attending the ceremony were Acting Chairman of Quang Ninh Provincial People's Committee Cao Tuong Huy and Chairman of TKV Board of Members Ngo Hoang Ngan.

Since 2010, Hon Gai Coal Company has focused on investing and exploiting underground mines in Thanh Cong, Cao Thang, Giap Khau and Ha Rang areas, with an annual raw coal output maintained stable from 2015 to present from 2 - 2.5 million tons/year, ensuring jobs and income for more than 4,000 workers in Ha Long City. Binh Minh Mine located in Ha Long City has been exploited since 2010, with a mining layer of -75 to -220m. Currently, the project has entered a phase of reducing output and is expected to end exploitation in 2026.

In order to maintain stable underground coal mining output of the Company, meet the requirements of TKV's coal production plan, and contribute to ensuring national energy security in the period of 2020-2045, since November 2020, Hon Gai Coal Company has implemented the project "Mining below -220 level of Binh Minh mine" in the exploitation layer from -220 to -350m. This is a project that is exploited in succession of the project in the exploitation layer from -75 to -220m with the studied seams including 5 seams from seam 1 to seam 5.

The project "Mining below -220 level of Binh Minh mine" has a total investment of 1,100 billion VND, with raw coal reserves of more than 9 million tons, capacity of 500,000 tons/year, exploitation for 21 years, exploitation level -220 to -350m.

The project includes 2 continuous mining furnaces, 1 mechanized furnace with a capacity of 300,000-350,000 tons/year and 1 chain frame furnace with a capacity of 200,000-250,000 tons/year. At the same time, it will maximize the use of automated conveyor technology in the mine and on the ground, delivering raw coal directly to the Hon Gai Coal Selection Company - Vinacomin.

Currently, the units exploiting the deepest mines of TKV are Ha Lam Coal Joint Stock Company and Nui Beo Coal Joint Stock Company, Ha Long City, both exploiting at a depth of more than 300m below sea level.

Previously, on August 5, 2023, the project "Renovating and expanding the capacity of Cao Son coal mine" with a total investment of more than 1,800 billion VND, an exploitation capacity of 4.5 million tons of raw coal/year with a coal reserve of 51.9 million tons was started.

In the coming time, TKV will continue to promote the implementation of mine development projects such as the Ha Rang (Hon Gai Coal) and Tan Yen (Uong Bi Coal) underground mine projects to increase output in the coming years, meeting the coal needs of the economy and the development requirements of the Group.
