Abstract
Six samples of G coal characterized by different vitrinite reflection coefficient (Ro,r = 0.64–0.74%) are investigated. With increase in Ro,r, the plastic-layer thickness y increases from 7 to 17 mm, the free-swelling index SI from 0.5 to 3.5, and the Roga index RI from 1 to 21. The temperature range of plasticity expands from 34 to 94°C. The results clarify the difference in clinkering properties of the gas coal.
