Mines targeted will be those with an annual output of less than 90,000 tons that fail to adhere to safety rules, and those based on substandard coal resources that are prone to accidents, the State Council, China's Cabinet, said in a statement yesterday.
Approval will also end for new coal mines with an annual capacity of less than 300,000 tons.
Accidents are common in China's mines, which are the deadliest in the world. According to the official Xinhua News Agency, 1,384 people were killed in coal mine accidents in 2012, and two-thirds of accidents each year are in small mines.
China has deep reserves of coal and 12,000 coal mines.
