There are 6794 coal mines in China, with a total capacity of 53.09 billion tons / year. Among them, the effective production capacity is 47.83 billion tons / year, accounting for 90% (according to the China Coal net), and the long-term production and shutdown capacity is 526 million tons / year. China Coal net reporter held the 2017 annual report of coal industry development conference in March 27th, and was informed that this data was cut to June 2017.

Chen Yangcai, director of the Ministry of statistics and information of the China Coal Industry Association, includes three types of productive capacity, namely, the production of normal production mines, new mines and the expansion of the mine, and the ineffective capacity refers to the long-term shutdown and shutdown of production capacity.

In the effective production capacity, there are 3822 mines in the normal production, the capacity of 32.54 tons per year, the 337 new mines, the capacity of 856 million tons / a year, and the expansion and expansion of the mine 1274, with the capacity of 6.73 tons per year.

In the inefficient production capacity, there are 1503 long-term production discontinued mines, the capacity is 2.69 million tons / year, and 666 mines have been built for a long time, with a capacity of 2.57 billion tons / year.

According to Chen Yangcai introduction, in 2017 the national coal production capacity utilization rate of 68.2%. 100 coal mine association report, mine capacity utilization rate of 98.7%; open to mineral utilization rate is 86.2%. In the region, the productivity of the northwest region is the highest, the southwest is relatively low, only 62.2%, and the northeast is 66.2%, and over 90% in North China, central China and East China.
