Research on Tectonic Coal Structure Based on NMR Technology

摘要

The understanding of coal body structure has important research significance for the prevention of coal and gas outburst and the development of coalbed methane. In order to further determine the difference between the primary structure coal and the structural microstructure of coal mines, and analyze the coal bed gas storage and migration control mechanism of coal body structural characteristics, the microstructure of structural coal in Sihe Coal Mine was tested by NMR technology. The structural characteristics of the coal body were mainly analyzed by obtaining maps, and the structural information of C, H, O and other related functional groups was quantitatively analyzed. The research results provide a technical reference for the study of coal microstructure.
