The Tokchon Area Coal-mining Complex and the Pukchang Area Youth Coal-mining Complex carry on the scrupulous operation and guidance to ensure the uninterrupted coal production under the closure condition.

Workers of several coal mines have directed efforts to securing new coal fields and raising the rate of mechanization.

The Kaechon and Anju area coal-mining complexes make big strides in coal production. Their workers showed high results in the capital and preliminary tunnellings and secured lots of spare cutting faces.

The Kujang and Hamnam area coal-mining complexes, too, have over-fulfilled their daily production plans by conducting a vigorous mass movement and stepping up the reinforcement of production processes and equipment.
