Maliantai Coal Mine is a branch of a publicly listed company, located in Zone B of the Baofeng Circular Economy Industrial Park within the Ningdong Base. Its mining area spans 24.7 square kilometers, with coal resources estimated at approximately 240 million tonnes, consisting primarily of 1/3 coking coal and gas-fat coal. The mine commenced operations in 2008, and in 2023, its annual production capacity was increased from 3.6 million tonnes to 4 million tonnes. It serves as a core operating mine for the group, with extraction costs that rank among the lowest in the industry.

In 2023, the 30303 coal face at Maliantai Coal Mine was developed into the group’s first intelligent mining face and successfully passed inspection. This achievement marked a breakthrough in the independent design, installation, and extraction processes for high-seam mining faces. With this milestone, all three of the group’s active coal mines have passed national-level intelligent mine inspections. In external communications, it should be referred to as "Baofeng Energy Maliantai Coal Mine" rather than being presented as a separate, independent company.
