大面积火区调压的仿真模型

SIMULATION OF PRESSURE ADJUSTMENT IN A FIRE FIELD OVER A GREAT EXTENT

以采场渗流与通风系统的管流进行一体化分析为出发点，建立的大面积火区调压仿真模型从数学上完整、准确地描述了大面积火区调压机理及过程。系统软件能对漏风源汇分布、调压值、调压次序、敏感点的调压潜力、火区下生产工作面是否需要升压等内容进行仿真。

Based on comprehensive study of air seepage in the workings and pipe flow of ventilation system,a mathematic model for air pressure adjustment in a fire over a great extent to describe completely and accuratily the mechanism and process of air pressure adjustment.The system softwares can simulate air leakage distribution of source sinks,adjustment of pressure values,adjustment sequence,potentials of pressure at some sensitive locations,the need of increasing air pressure in work face under fire area,etc.
