The Pukchang Area Youth Coal Mining Complex carried out its October production plan through a brisk mass technological innovation movement.

The complex raised the mining rate by introducing advanced working methods and improving the performance of equipment, readjusted and reinforced a hundred and tens of coal wagons and produced thousands of V-shaped steel props.

The Namdok Youth Coal Mine has steadily increased production by ensuring equipment and technical management in a responsible manner.

Similar successes are witnessed at other coal mining complexes.
