摘要
The main coal seams in Zhongliangshan mining area are analyzed by drawing macerals ternary diagrams and coal facies diagrams in consideration of the maceral classification of ICCP 1994 system. The seams are characterized by the predominance of semi clairain and a lot of structural coal, which is a result of Epigenetic tectonic activity. The petrographic composition is dominated by vitrinite, in which collodetrinite and vitrodetrinite are the major macerals. The sedimentary environments deduced from petrographic composition and coal facies diagrams vary from low delta plain to limnic environment, which belong to Rheotrophic, the mires were influenced by marine flooding.
