摘要
通过对新田矿区含煤地层研究，探讨了矿区龙潭组的沉积特征和聚煤规律，得出矿区龙潭组为三角洲与泻湖-潮坪沉积复合体系，成煤时期的不同沉积环境，聚煤沉阵幅度小，沉积速度和物质补偿均衡，有利于泥炭堆积，因此矿区含煤层教、煤层厚度较稳定。
Analyzed Xintian mining area coal - beating strata in Qianxi, Guizhon. Discussed the mining area longtan fonnation depositional features and coal - accumulating patterns, Considered that the longtan formation belong to a delta and lagoon - tidal flat depositional compound system. Deffrerent depositional environments, lesser settling scope, balanced settling velocity and material compensation during coal- forming stage were favorable to peal accumutation. Thus the coal seam number and thickness are stable in the mining area.
