摘要
煤的镜质组反射率各向异性性质反映了压力作用下的组构特征。本文根据实测结果,探讨了涟源煤田无烟煤镜质组反射率的各向异性特征及其与构造的关系,并以镜质组反射率椭球体为应变标志物,对涟源煤田进行有限应变分析,论证该煤田的应变类型和应变场的变化规律。
The anisotropic properties of the ccal vitrinite reflectance represent the fabric characters under pressure. Bassed on the measured results this paper describes anisotropic properties of the anthracite vitrinite reflectance and their relation with the structure in the Lianyuan coal field. The ellipsoids of the vitrinite reflectance are used as strain mark to make the finite strain analyses of Lianyuan coal field in the paper. Furthmore, the author has expounded the strain patterns of the area and the regularity of the strain field.
