| 摘 要： | 介绍了煤的光学各向异性的成因及其用于构造分析的原理。运用该原理首次对渭北煤田东部矿区煤镜质组反射率进行了研究，从煤层光学各向异性的产生机理分析，证明了本区变形历史中曾经受了强烈的侧向挤压。区内煤层变形的主要动力是来自ＮＷ－ＳＥ方向的挤压作用

| Abstract: | The paper shows the cause of formation of optical anisotropy of coals and the Principle used in the analysis of tectonic. The vitrinite reflectance has been firstly studied and it is proved that this region had ever undergone violent lateral pressure in the history of deformation through the mechanism analysis of the optical anisotropy of the coal. The main stress of the coal seam deformation comes from the pressed action of northwest and southeast orientation. |
