Pyongyang, March 21 (KCNA) -- Mines and smelteries in the mining industry of the DPRK conduct a brisk technical innovation emulation to boost the production.

The Jungsan Mine has over-fulfilled its daily plan for phosphorus concentrate production by pushing ahead with technical innovation to raise the operation rate of equipment.

While reinforcing the tunneling forces and giving precedence to securing cutting faces, Yongyu and Phungnyon mines have raised production results every day through updating of the technical performance of excavators and ore conveying equipment.

Munphyong and Manpho smelteries have conducted technical innovation emulations among workshops, workteams and shifts. And the Unpha Mine and other nonferrous metal ore production units are bringing about a surge in production by introducing efficient blasting methods and raising the carrying capability. -0-
