Topological 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, and the reason of the occurrence of reverse branches after network calculation is explained on the aspects of topological theory of ventilation network. We study the automatic generation of the topological relationship and automatic simplification of complicated ventilation network. Through simulation of tree growth, we develop a simple, effective and adaptable method, the "Path Tree Depth-first Growth" method, which can be used to search all paths of two arbitrary nodes. Different from previous research, the simplified theory of ventilation network and the path algorithm are simple, effective and adaptable, which are important to theory research and program design. © 2009.
