摘要大型地下洞库群施工通风问题，通常采用压人式通风或增设通风竖井来解决。竖井多依据经验或场地情况设置在洞库埋深较浅的位置，风网构成混乱，导致局部通风质量差；竖井自然通风受内外温差、竖井深度等影响非常大。文章依托锦州地下储油洞库的施工通风，基于通风网络理论，引入巷道式通风计算方法，对洞库群三种通风工况进行了通风计算和设备配置研究。研究结果表明，采用竖井VI布置轴流风机压入新鲜空气的方式，将施工通道（从地面进入洞库的施工运输通道）进口作为污浊空气排出口，能够有序形成大循环通风良性网络；竖井排风方式需要多台风机同时开启，费用较高，而且冬季利用竖井自然通风作用并不明显；竖井与洞室连通后（即储油洞室上层完成后），如果通风距离长，可全采用压入式辅以洞内射流或者完全使用射流风机引流。

英文摘要：

Usually it is necessary to use forced ventilation or a large number of ventilation shafts to solve construc- tion phase ventilation problems in large scale underground caverns. Since ventilation shafts are mostly set up in ac- cordance with experience or site conditions, they are generally located at a relatively shallow depth in an oil storage cavern, resulting in a ＂disordered＂ ventilation network, leading to poor local ventilation. Shaft depth and the temper- ature difference between inside and outside have a great effect on the natural ventilation of the shaft. Taking the con- struction ventilation of the Jinzhou underground petroleum storage cavern as an example, this paper introduces a cal- culation method for gallery ventilation based on ventilation network theory in order to study the ventilation calcula- tion and equipment configuration for three ventilation configurations in a cavern group. The results show that using the entrance of the construction adits （construction transport channels from the ground into the cavern） as a viable air outlet and forcing in fresh air with an axial flow fan at the shaft mouth results in an orderly circulation in the ven- tilation network. Using a shaft to exhaust air requires more than one fan operating at the same time, which means higher costs and, additionally, the natural ventilation effect of shafts is not sufficient in winter. When the shaft is con- nected to the cavern （i.e., the upper layer of the petroleum storage cavern is completed）, it is possible to adopt forced ventilation supplemented by jet flow, or it may be necessary to use full jet flow if the ventilation distance is long.
