title: <b>Statistical results of coal petrographic identification of the B-coal seams in the Xishanyao Formation</b>

description: 4.1.1 Maceral composition and vitrinite reflectanceThe organic constituents of the coal are dominated by inertinite, averaging 69.52%, 70.05%, and 50.73% in the B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub> seams, respectively. Vitrinite is secondary, accounting for 25.76%, 26.43%, and 37.89% in the same seams, with minor liptinite present. The maximum vitrinite reflectance (R<sup>o</sup>max) of the B<sub>2</sub> seam ranges from 0.30% to 0.55% (mean 0.40%); that of the B<sub>1</sub> seam ranges from 0.27% to 0.65% (mean 0.39%); and that of the B<sub>0</sub> seam ranges from 0.49% to 0.50% (mean 0.50%). Coals from the B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub> seams of the Xishanyao Formation are classified as low-rank. Among the inorganic constituents, clay minerals are overwhelmingly predominant .4.1.2 Industrial characteristics of coalOn an air-dried basis, moisture contents (Mad) in the B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub> seams average 12.59%, 10.75%, and 9.64%, respectively, indicating ultra-low to medium moisture overall. Dry-basis ash yields (Ad) average 10.35%, 9.09%, and 18.92%, spanning ultra-low-ash to high-ash , with low-ash coals predominating. Dry, ash-free volatile matter (Vdaf) averages 33.04%, 32.61%, and 37.70%, corresponding to medium- to high-volatile coals. Dry-basis total sulfur (St,d) averages 0.71%, 0.59%, and 0.64% for B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub>, respectively. The mean oxygen uptake capacity (OUC) is 1.01, 1.05, and 0.93 cm³/g for B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub>, suggesting an elevated tendency toward spontaneous combustion.4.1.3 Elemental composition of coalOrganic matter represents the principal chemical component of coal, dominated by carbon, hydrogen, nitrogen, and sulfur, with elemental abundances summarized in Table 1. On a dry, ash-free basis, the mean carbon contents (Cdaf) of the B<sub>2</sub>, B<sub>1</sub>, and B<sub>0</sub> seams are 78.96%, 79.48%, and 76.51%, respectively. The corresponding mean hydrogen contents (Hdaf) are 3.52%, 3.59%, and 3.76%, while mean nitrogen contents (Ndaf) are 0.78%, 0.75%, and 0.84%, respectively.
