英文摘要: Theory and technology of three-dimensional modeling had greatly promoted the production efficiency and safety of underground mines. Especially the development of multi-scale seamlessly integrated modeling for the underground space of mine can provided a three-dimensional model for mining design, associated safety analysis and so on. In this research, multi-scale seamlessly integrated modeling for underground space of mine, chosen as our research focus, including three key issues: principle of multi-scale modeling, model of seamlessly integrated modeling and dynamic updating mechanism of that model. Therefore, according to the multi-stages of mining process, with GTP, CD-TIN, TEN, MDEM, CSG, multi-section suturing and other modeling elements to build seamless integration model of underground mine space, and meanwhile, using method of dynamic embedment and entities intersection to solve the model updating problem, so as to providing a highly reliable three-dimensional model for the production design and safety analysis of underground mines, and thus contributing to efficient, safe and sustainable exploitation of underground mine.
