Some formed in living plant tissues, and …
1. Introduction. With the coal resources gradually entering the deep mining stage, under the complex environment of "three-high and one-disturbance," the coal and rock are more prone to fracture and lose stability, leading to more dynamic disasters such as rockburst and coal and gas outburst [1 – 4].Moreover, in recent years, the coal-gas compound dynamic …

— Properties of the examined anthracites change characteristically with change in rank: anthracitic coal→anthracite→meta-anthracite. It was established that volatile matter content, hydrogen content and calorific value decreased whereas moisture content, carbon content and coke yield increased with the increase in the rank of the anthracites.
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbon-rich, and harder material. The four ranks are:Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, …
— Coal is a sedimentary rock composed of both organic and inorganic materials.

101 coal was first cut into a 102 mm×51 mm×51 mm cuboid using a rock cutting machine, 102 and then the six sides of the coal samples were polished by a double-end grinder. 103 Through polishing, the unevenness of the six sides of the coal samples is less than 104 0.01 mm. Finally, the standard coal samples used for uniaxial compression and AE
— Anthracite coal, mined from the planet's oldest geological formations, has spent the longest time underground. The coal has been subjected to the most pressure and heat, making it the most compressed and hardest coal available. Hard coal contains greater potential to produce heat energy than softer, geologically "newer" coal.

— The average reservoir pressure of the #3 coal seam prior to CO 2 injection was 1241 kPa (180 psia) at a depth of 472 m. The absolute permeability of the coal seam prior to CO 2 injection was 12.6 milli-darcy (md), which was based on an effective permeability to gas of 1.8 md and a gas saturation of 40.8%.
Anthracitic rank marks the beginning of distinctive physical and chemical changes to coal termed anthracitization, graphitization, metadiagenesis, and telodiagenesis in different reports (see figure). The most distinctive physical change at anthracite rank, is the development of conchoidal fracture and the loss of cleats in coal.
