| Abstract: | According to the theories of heat transmission and multihole agent seepage flow, combined with the phase of stope temperature, the numerical simulation concept of stope temperature field of multihole agent is established with the computer.Meanwhile, with the finite element method with triangleas its basic unit, the numerical method to solve stope temperatur question is discussed. with FORTRAN and BASIC languages, the programs of the computer simulation and automatic drawing of constant temperature lines are worked out. By means of actual example simulation, with the method of the computer simulation can te determined high temperature poins of the stope and effect of the air flow on the stope temperature, clear and definite the key point fire prevention project, the qualitative information to early stage prediction of ignited of stope is provided. |
