At workplaces, officials of various mines solved knotty problems and encouraged the workers to increase the production through political work.

The Phungnyon Mine put spurs to the revitalization of production while settling the sci-tech problems in cooperation with the relevant units. As a result, the mine raised the production of minerals twice the planned on Jan. 3 alone.

Workers at the Yongyu Mine produced apatite concentrate nonstop by pooling their technical skills and experience, thus registering high results in the production of minerals.

Those of the Unpha Mine and other mines, too, have over-fulfilled their daily production plans while operating equipment at full capacity to suit the present conditions.
