The six major coalfields in Shanxi: location, coal types, reserves and production capacity, main mining areas.
Datong Coalfield:
LocationLocated in the northern part of Shanxi Province, spanning Datong, Shuozhou and other areas, mainly in Datong.
Reserves and ProductionCoal reserves are about 34.18 billion tons, with a production of about 90 million tons. It is one of the coalfields in Shanxi that produces and exports a large amount of coal.
Coal Types and CharacteristicsMainly weakly caking coal from the Jurassic period, and gas coal from the Carboniferous-Permian period. The coal quality has a low degree of metamorphism, with weakly caking coal having low ash, low sulfur, high volatile matter, and poor caking properties; gas coal has high ash content and low to high sulfur content, some of which can be used as coking coal.
Main Mining AreasDatong mining area and some surrounding municipal coal mines and township coal mines, includingJinhua Palace Coal Mineand other mines.
Ningwu Coalfield:
LocationLocated in the central northern part of Shanxi Province, covering Ningwu, Yuanping and other areas.
Reserves and ProductionThe coalfield area is 3087 square kilometers, with coal reserves of 97.434 billion tons and a production of over 37 million tons.
Coal Types and CharacteristicsMainly thermal coal, with some gas coal. It has high ash melting point and stable quality, but relatively high ash and sulfur content.
Main Mining AreasIncluding the Pingshuo mining area, Xuangang mining area, Huabei Tun mining area, etc.,Pingshuo Open-pit Coal Mineis very famous.
Hedong Coalfield:
LocationLocated in the western part of Shanxi Province, east of the Yellow River, distributed in cities such as Lüliang, Linfen, and Yuncheng.
Reserves and Production:The coalfield area is 15,285.5 square kilometers, with coal reservesof 233.52 billion tons, and a production of about 26 million tons.
Coal Types and CharacteristicsMainly distributed along the Yellow River, starting with coking coal from north to south, with increasing metamorphic degree, leading to lean coking coal, lean coal, and poor lean coal. The coal quality is of medium metamorphic degree, with Liulin coking coal being high-quality coking coal, medium ash content, low to medium sulfur, and strong caking properties.
Main Mining AreasImportant mining areas include Li Mining Area and Xiangning Mining Area, with mines such as Shaqu No. 1 Coal Mine.
Xishan Coalfield:
LocationLocated in the central part of Shanxi Province, close to Taiyuan City, with a superior geographical location.
Reserves and ProductionThe coal-bearing area is 1898.4 square kilometers, with coal reserves of 23.367 billion tons and a production of about 32 million tons.
Coal Types and CharacteristicsMainly coking coal, with high-quality coking coal, fat coal, lean coal, and poor coal. The coal quality is of medium metamorphic degree, with medium ash content, and the volatile matter of fat coal and coking coal generally ranges from 20 to 28, with strong caking properties, making it a high-quality scarce coal type.
Main Mining Areas:Xishan Mining Area,Gujiao Mining Area, Qingjiao Mining Area, with mines such as Guandi Mine and Malan Mine.
Huoxi Coalfield:
LocationLocated in the southwestern part of Shanxi Province.
Reserves and ProductionThe area is 6255.6 square kilometers, with resources of 57.82 billion tons and a production of about 40 million tons.
Coal Types and CharacteristicsAll are coking coal, with 1/3 being coking coal, fat coal, coking coal, and lean coal. The coal quality is of medium metamorphic degree, with the northern mines mainly producing high-sulfur coal, while the southern mining areas produce coking coal with high volatile matter.
Main Mining Areas:Huozhou Mining Area,Fenxi Mining Area, Lingshi Mining Area, etc., with coal mines such as Xinzhizhi and Tuanbai.
Qinshui Coalfield:
LocationLocated in the southeastern part of Shanxi Province, between the Taihang Mountains, Lüliang Mountains, and Wutai Mountains.
Reserves and ProductionThe coal-bearing area is 30,500.1 square kilometers, with resources of 331.65 billion tons, and a production of up to 105.3 million tons, making it an important coal production base.
Coal Types and CharacteristicsMainly anthracite and semi-anthracite, with lean coal and coking coal as secondary. The anthracite from this coalfield is high-quality chemical coal and thermal coal, such as high-quality anthracite from Yangquan and Jincheng.
Main Mining AreasYangquan Mining Area, Lu'an Mining Area,Jincheng Mining Area, Qin Yuan Mining Area, Anze Mining Area, etc., with mines such as Yangquan Xinjing Mine, Lu'an Zhangcun Mine, and Jincheng Sihe Mine.

The coal mining techniques that are commonly used underground in coal mines.
The blasting mining process uses blasting methods to extract coal mines. In practical applications, the selection of blast holes is crucial. If the design is improper, the blasting effect will be affected. In mild cases, there may be blasting deviations, impacting the extraction volume; in severe cases, it can cause losses to life and property. A large amount of dust is generated after blasting, and the mining area needs to be managed post-blasting.
