The structure of tectonically deformed coals shows some characteristics and regulations on
the ultra-scale when influenced by different factors such as temperature, pressure and …

Coal structure refers to the internal structural characteristics of coals including the degree of
macroscopic and microscopic deformation, pore structure, and mechanical properties after …

Coal seams are one of the targeted geological bodies for CO 2 sequestration. Coal structure
deformation is a significant feature of the interaction between CO 2 and coal seams. The …

In order to identify the parameters that best characterize the chemical and structural
evolution of organic matter during coalification, the relationships between optical, chemical …

Small angle neutron scattering and adsorption experiments have been performed on a
series of humic coals from the Ruhr Basin, Germany. The coals represent the range of rank …

The present work is focused on the characterization of natural samples as end-member
products of coalification process—semi-graphites and graphites, and on the characterization …

Tectonic deformations damage the macrostructure and impact the macromolecular
structures of coal. In this study, high-resolution transmission electron microscopy (HRTEM) …

The flattening of nanoscale pores is a crucial step in the process of anthracite graphitization,
which primarily occurs due to lithostatic pressure or tectonic stress. Anthracite, a highly …

摘要采用压汞实验和低温液氮吸附实验分析了构造煤的孔隙结构特征, 结合地面煤层气抽采试验
, 探讨了孔隙对煤层气产气特征的影响. 论文将煤中孔隙划分为4 种类型: 吸附孔隙(孔径小于 …

There is a more consanguineous relation between nano-scale deformation of coal structure
and metamorphic-deformed environment. In different metamorphic-deformed environments …
