Coal was slowly formed hundreds of millions of years ago when a large number of plants were buried in the ground.
Whether it is China or the rest of the world, coal is usually divided into genetic classification and industrial classification.(or practical classification) two systems. The genetic classification is based on the different coal-forming primitive plants.
