BEIJING - The economic planner and other relevant departments have been soliciting suggestions before formally introducing drastic measures to cut back on coal overcapacity, a report said Thursday.

The measures include a pause in new coal mine projects, closing of outdated production facilities, directing "zombie" companies to close and expediting coal-electricity integration, according to Thursday's Economic Information Daily.

In the coming three years, China plans to close 4,300 coal mines, remove outdated production capacity of 700 million tons and relocate 1 million employees.

The central government earmarked 30 billion yuan ($4.57 billion) to support the relocation, according to the report.

Domestic coal demand shrank 2.9 percent year on year in 2014 and is expected to have dropped 4 percent in 2015, as demand dwindles due to the economic slowdown, restructuring and environmental protection, said Jiang Zhimin, deputy head of the China National Coal Association.

In the past five years, China has eliminated about 560 million tons of coal production capacity and closed 7,250 coal mines, according to Chen Yangcai, head of statistics and information with the association.

China had about 11,000 coal mines at the end of 2015 with a total capacity of 5.7 billion tons. Among these, some 1,000 had annual capacity above 1.2 million tons, about 400 more than in 2010.
