Abstract

Since 1942

research on the coal macromolecular structure model has evolved through three stages:cognition and exploration

high-precision interpretation and visualization

and large-scale model construction and wide application. The key technologies are closely related to the efficient exploration

development

upgrading

and conversion of fossil energy

and the modelling framework is evolving towards AI-driven

high-precision

and large-scale paradigms. Integrating the existing research with elemental analysis

spectroscopic testing

and high-resolution transmission electron microscopy observation

an efficient method is proposed for constructing large-scale and high-precision coal macromolecular structure model. Supported by this method

the study systematically elucidates the macromolecular structure characteristics of deep coal seams in Ordos Basin

and constructs coal macromolecular structure model with varying maturities. Validation results demonstrate that both the physical and chemical structures of the model are highly consistent with experimental testing results. Based on the construction of high-precision and large-scale model

combined with molecular simulation and modern analytical and testing techniques

a bridge between microscopic processes and macroscopic responses has been established

enabling the coal macromolecular structure model to demonstrate broad application prospects in deep coalbed methane resource exploration and evaluation

development and production stimulation

fundamental research

and technological frontiers. Facing the dual challenges of coal organic structural complexity and high-performance computing demands

future research will pivot from static characterization to dynamic coupling and intelligent design

with key emphasis on developing efficient multiscale bridging algorithms and high-performance computing methods

thereby providing revolutionary theoretical tools for the precise and efficient exploration and sustainable development of coalbed methane.
