摘　　要：由于不同地点热源对局部通风系统的影响不同,就倾斜巷道和水平巷道里的热源分开进行讨论。由连续方程以及动量守恒方程可知,水平巷道里的热源会在巷道里形成热阻力,对风流产生节流效应;由自然风压理论可知,倾斜巷道里的热源会形成沿巷道倾斜方向向上的热风压,不同大小的热风压会对巷道里的风流造成不同的影响,分析所有可能的影响结果。最后,根据不同地点的热源对局部通风系统造成的不同影响提出了相应的对策。Because the influence on local ventilation system varies with the location of heat source, in order to make the analysis more comprehensive, in this paper, the heat sources in inclined roadways and in horizontal tunnel are discussed separately. According to the mass conservation equation and the momentum conservation equation, the heat source in the horizontal roadway forms heat resistance and thus has the throttle effect on air flow. According to the natural wind pressure theory, the heat source in inclined roadway would form hot air pressure opposite the inclined roadway direction. Different hot air pressure exerts different effect on air flow in the road- ways. In this paper, all the possible results are analyzed. Finally, the corresponding countermeasures based on different impact of heat source on the local ventilation system are proposed.
