Technological Methods of Digital Reconstruction of Complex Mine Cracks are the Use of Technological Processes in Mining

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: collection and fidelity of multi-physical field data of the fault structures, the transmission of multi-physical field data, the normalization of multi-physical field data, and 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.
