| 摘 要： | 以大量勘探钻孔资料及野外观测为基础，对澄合矿区煤系地层沉积环境及成煤条件进行了分析研究，阐述了本区煤系主要在岸线附近的滨海平原及近海内陆环境沉积。其中滨海及泻湖波浪带最有利于成煤，因受地壳近南北向不均衡沉积的控制，区内煤系及煤层变化多呈南北向带状分布，为今后的地质勘探和煤矿开采提供了依据。

| Abstract: | Based on large quantity exploratory borehole data and field observation, analyzed Chenghe mining area coal measures strata sedimentary environment and coal-forming condition,expounded that the coal measures in the area were mainly deposited in littoral plain along the coastline and sea adjacent inland environment deposits.Among them,the littoral and lagoon unda zones were the best coal-forming environments. Since controlled by the near NS crustal unequilibratory subsidence, the varying of coal measure and coal seams in the area are presented mainly NS zoning distribution. It can provide a basis for geological exploration and coal mining henceforth in the area. |
