Abstract
Visualization of complex geological structures can technically support the accurate prediction and prevention of coal mine disasters. This study proposed a new digital reconstruction method to visualize geological structures based on establishing a virtual model in the digital twin system.
This methodology for the digital reconstruction of complex fault structures comprises the following four aspects: (1) collection and fidelity of multi-physical field data of the fault structures, (2) the transmission of multi-physical field data, (3) the normalization of multi-physical field data, and (4) digital model reconstruction of fault structures.
The key scientific issues of this methodology to be resolved include in situ fidelity of multi-field data and normalized programming of multi-source data. In addition, according to the geological background and conditions in Da’anshan coal mine in western Beijing, China, a preliminary attempt is made to reconstruct a digital model of fault and fold structures using the methodology proposed in this study.
