【Abstract】 The application of the numerical simulation of the undetrmined boundary problem is discussed in this paper and an example of the pillarless ventilation field in Luling Coal Mine, Huai Bei is given as Well. Parameters are adjusted automatically with the computer and parametrs and boundary values are identified. In addition, the finite-element analysis is made with the computer. The optimal blow network of the air blow field is drawn and equi-potential lines are printed automatically, thus providing data and basis for ventilation safety.更多还原
