As of now this year, more than 450 reserve coal faces have been secured throughout the Ministry of Coal Industry.

The Sunchon Area Youth Coal-mining Complex made progress in securing deposits of coal by intensively dispatching tunneling platoons to the areas with rich deposit and favorable mining condition and fully supplying equipment and materials.

The Kaechon Area Coal-mining Complex and the Tokchon Area Coal-mining Complex have made successes in securing reserve coal faces by scrupulously conducting the work to improve the general technical and skill levels of tunneling workers and organizing a campaign in which one overtakes and learns from others and swaps experiences with them.

The Tukjang Area Coal-mining Complex and the Kujang Area Coal-mining Complex are raising the utilization rate of tunneling equipment including rock drills and compressors and tightening cooperation among processes to secure much more deposits of coal.
