摘 要:随着矿井通风系统日趋庞大,通风网络拓扑结构也更加复杂,这给矿井通风系统分析、优化和预测工作增加了很大难度。为实现对复杂通风网络的简化,提出复杂通风网络的等效简化、模糊简化和复合简化三种方法,对等效简化过程中应遵循的原则和风阻、风机性能等参数的等效变换进行研究。并在孔庄煤矿的通风网络解算中得以应用,结果表明:对孔庄煤矿通风网络进行复合简化,能减少节点比例为35.9%,减少分支比例为38.6%,且误差不超过5%;若只对其通风网络进行等效简化,减少节点比例为27.2%,减少分支比例为29.1%,则不存在任何误差。With the mine ventilation system getting larger and larger and the topology structure of the mine ventilation network getting more complicated,more difficulties would be increased to the analysis,optimization and prediction of the mine ventilation system.In order to simplify the complicated ventilation network,three methods including the equivalent simplification,fuzzy simplification and complex simplification of the complicated ventilation network were provided.A study was conducted on the principle of the equivalent simplification process and the equivalent transfer of the air resistance,ventilator performances and other parameters,which were applied to the mine ventilation network resolution in Kongzhuang Mine.The results showed that a complex simplification was made on the mine ventilation network in Kongzhuang Mine,the node percentage was reduced by 35.9%,the branch percentage was reduced by 38.6% and the error was not over 5%.If the equivalent simplification was made only on the mine ventilation network,the node percentage could be reduced by 27.2%,the branch percentage could be reduced by 29.1% and there would be no error existed.
