Coal is divided into four classes: anthracite, bituminous, subbituminous, and lignite. Elemental analysis gives empirical formulas such as C 137 H 97 O 9 NS for bituminous coal and C 240 H 90 O 4 NS for highgrade anthracite. Anthracite coal is a dense, hard rock with a jetblack color and a metallic luster. It contains between 86% and
The large diameter pressure relief borehole is one of the most effective technical means to prevent and control rockburst during deep mining. Based on the engineering background of rockburst mines, the mechanical model of coal energy dissipation of large diameter pressure relief holes is established by theoretical analysis, and the approximate formula for

Coal Combustion for Insufficient Air. By weight, the requirement of air for providing this much O 2 is After combustion of one gm carbon(C), product of combustion contains only 2.33 gm of CO and of N 2. From equation (1) and (2) it is clear that due to insufficient air combustion, the heat lose during 1 gm of coal combustion is . Combustion

Coal is primarily used as fuel to generate electric power in the United States. In coalfired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into highpressure steam, which drives a turbine, which produces electricity. In , about 23 percent of all electricity in
