| 摘 要： | 在对研究区地质资料进行系统分析的基础上，运用大地构造和沉积学原理和方法，深入探讨了区域构造演化及其对煤与瓦斯的控制作用。结果表明，研究区构造演化对煤层的控制作用显著，主要表现在对煤层展布、埋深和煤体结构等三个方面：研究区主煤层瓦斯含量的区域分布呈现出“南高北低、东高西低、东南部最高”的展布格局，是印支期未至燕山早期的北西西向的逆冲推覆．以及后期喜马拉雅期不均匀沉降叠加作用的结果。

| Abstract: | Based on systematic analysis of geological data in the research area, by the use of geotectonics and sedimentology theory and means, discussed characteristics of tectonic evolution and its controlling effects on coal and gas in Huaibei area in detail. The research results show that the coal seams were controlled significantly by the tectonic evolution in Huaibei area, including mainly distribution and buried depth of coal seams, coal structure and so on. The regional gas content distribution of main coal seams in the research area shows that the characteristics of ＂high in the south and low in the north, high in the east and low in the west, and highest in the southeast＂, which is the result of NWW thrusting nappe during the late Indo-China stage to early Yanshanian stage and uneven subsidence of each tectonic activity during the late Himalayan stage stacked effects. |
