coal production process

Coal Production an overview ScienceDirect Topics

World coal production increased by 3.1% in 2017 after falling for 3 years The trend changed in 2017 with a total production of 7549 Mt as per IEA Key Statistics 2018. Coal is made up of thermal coal, coking coal, and lignite, and the data for the last 3 years are tabulated in Table 2.2. About 75% of the total coal produced is steam coal. Table 2.2.
