Topology theory of mine ventilation network [PDF]
Procedia Earth and Planetary Science, 2009 AbstractTopological theory of ventilation network is the basis of mine ventilation simulation system. But there still exists disparity and insufficiency between theory and application. On the basis of in-depth study of ventilation network topological theory, the concept of the real and the simplest fuzzy topological ventilation network are put forward,
