Officials of the Ministry of Mining Industry in charge of the phosphate fertilizer industrial sector reviewed the production results and the implementation of the readjustment and reinforcement goal and took steps to solve knotty problems.

The Yongyu Mine, in cooperation with technicians of a relevant sector, has improved the technical performance of equipment in each process by finding out rock strata with many crushing cracks and perfecting measuring means.

It has also achieved successes in building stopes in pits by reinforcing the tunneling force and conducting the work for raising the tunneling workers' level of technique and skill.

The Phungnyon Mine vitalizes production by building a phosphate ore flotation process based on high-capacity air power loader and establishing its scientific operation system.

Such progress is made at the Jungsan Mine and other apatite mines.
