| Abstract: | This paper presents the petrological and metamorphic features of 10-11~# coal seam in Datong Jurassic coalfield on the basis of experimental results and points out that 10-11~# coal is most characterized by its high content of inertinite. The relation between the classification and technical properties of 10-11~# coal and its petrological characteristics is evaluated and the effect of sedimentary environment on the coal properties is discussed. The authors think that the maceral separation technology is useful for expanding the utilization of Datong coal in coking industry and the combination of petrological and chemical analysis is essential to rational use of Datong coal duo to its intrinsic maceral composition. |
