摘　　要：本文通过综合分析利用以往勘查成果资料,简要介绍了研究区内的含煤地层及可采煤层特征。研究区主要含煤层位为三叠系上统须家河组第七段(T_(3)xj^(7))和第五段(T_(3)xj^(5)),煤的化学组成以低灰-高灰分、特低-低硫、中-中高挥发分、特低-中磷、中-特高发热量为特征,煤类主要为1/3焦煤,次为焦煤。Through comprehensive analysis and utilization of previous exploration results,this paper introduces the characteristics of coal-bearing strata and workable coal seams of Tieshan area briefly.The main coal-bearing strata in the research area are the seventh(T_(3)xj^(7))and the fifth(T_(3)xj^(5))members of Upper Triassic Xujiahe Group.The chemical composition of coal is characterized by low to high ash,extra low to low total sulfur,medium to medium high volatile matter,extra low to medium phosphorus,and medium to extra high calorific value.It showed that the coal classes in this area is mainly 1/3 coking coal,secondary coking coal.
