摘　　要：兖州煤田是华北地区重要的煤炭生产基地,以往主要侧重于3煤的煤质分析与研究,系统地分析其他煤层的煤质相对较少。为了全面了解该矿煤质指标,采用煤地质学、地球化学等方法,通过采样、测试以及分析,对其水分、发热量、灰分和灰成分、硫分、挥发份和主要元素进行研究。研究发现:煤层自上而下灰分含量逐渐降低,硫分含量逐渐增高,挥发份含量逐渐加大;18上为中灰煤,其余煤层为低灰煤;太原组煤层富硫,山西组煤层低硫;各煤层均为中高发热量;山西组煤层的水分含量略高于太原组。太原组与山西组的煤层均属气煤,太原组煤层较山西组略偏肥煤。The Yanzhou coalfield is a major coal production base in North China. In the past, studies were mainly focused on coal quali- ty analysis of coal No.3, while relatively small systematic analysis on other coal seams. In order to comprehensively understand coal quality indices in the coahnine, coal geological and geochemical methods have been used. Through sampling, testing and analysis, stud- ied moisture, calorific value, ash content and composition, sulfur, volatile matter and main elements. The studies have found that from top to bottom of coal seams, ash content gradually decreasing; sulfur and volatile matter contents gradually increasing. Only coal No.18U is medium ash content coal, others are low-medium ash content coal seams. Taiyuan Formation coal seams are sulfur rich, while Shanxi Formation sulfur low. All coal seams have medium-high calorific values. Moisture content in Shanxi Formation coal seams is a little higher than in Taiyuan Formation coal seams. Coal rank of all coal seams belongs to gas coal, but coal seams in Taiyuan Formation are little biased to fat coal than in Shanxi Formation.
