摘　　要：根据通风网络回路能量守恒定律,介绍了热风压对通风网络分支风流状态影响的分析方法,提出了考虑热风作用条件下网络风流状态控制原理,针对潘三煤矿热风压对网络分支风流影响的实例,提出并实施了热风压作用下矿井通风网络风流状态的控制措施,达到了有效控制网络分支风流状态,实现潘三煤矿西风井风机切换期间矿井的安全。Base the energy conservation law of the mine ventilation network circuit, the paper introduced the analysis method of the warm ventilated air pressure influenced to the air current state in the ventilation network branch. The paper proposed the control principle of the air current state in the ventilation network in consideration of the warm air function. According tot the practical case of the warm ventilation air pressure influenced to the air current of the ventilation network branch, the paper proposed and practiced the control measures for the air current state of the ventilation network under the ware air pressure. The measures have efficiently controlled the air current of the ventilation network branch for the mine safety during the ventilators switching period in the West ventilation mine of Pansan Mine.
