摘要
在对沁水盆地郑庄井田3^#煤层形成背景分析的基础上,本文详细研究了3^#煤层的煤质特征。研究结果表明：井田内3^#煤层形成以后迅速被上三角洲平原分流河道、决口扇、溢岸沉积所替代,于分流间湾上发育泥岩沼泽、分布有限;3^#煤层为井田的主力煤层,且所处构造环境较为简单,水文地质条件较好;3^#煤为低硫、高热稳定性、特高热量值煤,定为无烟煤二号（WY2）和无烟煤三号（WY3）。该研究对于指导3^#煤的生产开采以及充分利用3#煤的经济价值具有重要意义。
On the basis of analyzing the forming background of 3^# coal seam in Zhengzhuang Coalfield,Shanxi Qinshui Basin,the paper probes into the coal quality characteristics of 3^# coal seam.Being of great significance for guiding for the production of 3^# coal mining as well as taking advantage of economic value of 3^# coal,the studies show that：distributary channel,crevasse splay and infact deposition of upper delta plain quickly replace3^# coal seam after its formation inside coalfield,in shunt between mudstone bay swamp,limited distribution;as the main coal seam,the structural environment of 3^# coal seam is relatively simple and its hydrogeological conditions is better;as low sulfur,high thermal stability,especially high calorific value coal,3^# coal is determined as anthracite coal Ⅱ（WY2）and anthracite coal Ⅲ（WY3）.
