| 摘 要： | 通过龙永聚煤盆地构造演化及富煤带赋存层段机理分析,发现聚煤盆地构造演化与富煤带展布有一定的相关性,主要表现在一定时期、一定空间、一定样式的构造与一定层段的富煤带在走向、倾向上,具有一定的相关性,即一定的富煤带产生在一定的滑覆、推覆构造及其组合中。龙永煤田西部主要产生印支期的滑覆断层,应寻找走向上的富煤带;龙永煤田东部主要产生燕山期的推覆断层,应寻找倾向上的富煤带;龙永煤田中部主要产生印支期及燕山期的组合滑脱断层,应寻找上推下留型、上滑下留型、滑褶集中型的走向、倾向的富煤带。此项研究为龙永煤田进一步寻找富煤带指明了方向,同类型的勘探区可以参考。

| Abstract: | After analyzed Longyong coal-accumulating basin tectonic evolution and coal-rich zone hosting sector mechanism has found that there is certain correlativity between tectonic evolution and coal-rich zone distribution. Mainly find expression in certain time, certain space, certain style structures have correlativity with strike and dip of coal-rich zones, namely certain coal-rich zone happened in certain decollement and nappe structures and their combination. In western Longyong coalfield are mainly Indo-Chinese Epoch decollements, ought to looking for strike coal-rich zones; eastern part are mainly Yanshanian Epoch nappe structures, looking for dip coal-rich zones; middle part are mainly Indo-Chinese and Yanshanian combined decollement, looking for coal-rich zones under nappes, under decollements, decollement and fold converging areas. |
