The Research Of Dynamic Simulation For Coalminefire Based On Physical Field Model

This paper focuses on the study about combustion characteristics of mine fire and the reason of flow disorder within fire period. Through establishment of math and physic model of classic fire spectacle, the rule of smoke spreading is found by the numerical simulation technology. Moreover, the mine fire network simulation technology is made use to study the technology which contains external fire source location and selection of escape route. Setting the fire accident of coal mine named LiSheng in TanJiaShan as the research target, visual software which is developed by author is used to locate the fire position, export the process of spreading of smoke and the optimum escape route of staff. Based on multivariate topology date, the model of classic coal mine accident spectacle is not only constructed but also the method of quick modeling is presented. Finally, combine with the record of numerical simulation and spectacle model, the virtual reality technology for fire and smoke under affection of physical zone is studied in detail, additionally, the key technology of coupling between CFD simulation and virtual reality software is achieved and example application is tested by the self-constructed virtual reality software. The research fruits can provide a new kind technology for mine fire prevention and management, accident investigation and rescue and mine staff safety education or training.
