The Ministry of Coal Industry has taken thorough-going measures for supplying materials and equipment to coal producers in time.

Coal mines under the Pukchang Area Youth Coal Mining Complex secured lots of preliminary coal fields while pushing forward the mining and transport to increase the coal output. They are now raising the level of mechanization by making air rotary puncher, various rake conveyors and multi-functional inertia-type loading and transporting equipment.

The Sunchon Area Youth Coal Mining Complex introduced multi-functional conveyors into subsidiary coal mines including the February 8 Jikdong Youth Coal Mine. Coal mines under the complex are increasing the coal production by applying rational blasting methods to tunneling.

The same is true of other coal mining complexes.
