Pyongyang, December 5 (KCNA) -- The Osoksan Granite Mine is one of leading processed stone producers in the Democratic People's Republic of Korea.
This year, the mine applied a new stonecutting method to raise the actual extraction rate twice than before.
The hexahedral stone extracted by the new method has no cracks and is arranged neatly.
The method helps considerably save manpower and materials like blasting agents, and it is much superior in aspect of labor protection to the previous method.
The mine has produced a large amount of processed stones needed for major construction projects.
