Apr 29, Preparation of Coal Samples. Anthracite coal obtained from Yangquan Mining Area in Shanxi Province, China, was used for the test. The location of Yangquan Mining Area is shown in Figure 1. The blocky coal samples were immediately sealed after collection from the fresh working face, packed, and sent to the laboratory.

Mar 10, 2021Coal dust is the product produced when coal is finely ground. Typically, it will be of a higher quality of coal such as anthracite and not lignite. Higher quality coals have higher proportions of pure carbon, and thus burn much more cleanly without the release of toxic gases such as those associated with the burning of bituminous coal.
