| 摘 要： | 以基础地质资料为依托,运用构造解析研究思路与方法,进行渭北石炭二叠纪煤田韩城矿区龙亭—合阳勘查区构造应力场分析,在此基础上揭示控煤意义。结果显示研究区自三叠纪后先后经历了印支运动期北北西向挤压、燕山运动中期北西西向挤压和喜马拉雅运动期北东向挤压兼右旋剪切与北西—南东向伸展断陷作用三期构造作用,最大主压应力方位分别为335°、285°、44°;北东东向正断层系控制了区内煤层空间赋存状况,其发育程度直接影响区内煤炭资源下一步勘查与开发进程。

| Abstract: | Based on the basic geological data, the tectonic stress field of longting-heyang exploration area in the Permian carboniferous coalfield of Weibei is analyzed by means of structural analytic research ideas and methods, and the significance of coal-controlling is revealed. Research results show that since the end of the Trias, the study area has experienced NNW squeezed tectonic activity in Indosinian movement period, NWW squeezed tectonic activity in middle Yanshan movement period, NE squeezed-right rotated and NW-SE stretching activity In Himalaya movement period. The maximum principal compressive stress positions are 335°, 285°, 44° respectively. The faults in NEE direction controlled the spatial distribution of coal seam, and its development directly affects the next exploration and development of coal resources in the region. |
