近年来,冶金矿山在调整通风系统过程中,采用了若干种独立通风的分流式网路结构,例如,棋盘式、上下行间隔式、平行双巷式以及梳式网路等等。这些分流式网路结构都有专用的回风道,对解决中段间、采场间风流串流,防止风流污染,起了很好的作用。但是,建立独立通风的分流式网路结构,比一般的非独立通风的混流式网路(即各中段无专用回风道或回风天井的网路),需要多开凿和维护相当数量的专用回风巷道。是否所有的冶金矿山均需建立独立通风的分流式网路结构?采用非独立通风的混流式网路的矿山应如何提高该种网路的通风效
In recent years, metallurgical mines in the process of adjusting the ventilation system, the use of a number of independent ventilation diversion network structure, for example, checkerboard, up and down spacing, parallel double lane and comb network and so on. These split-network structure has a dedicated return air duct, to solve the middle section, the wind flow between the stope, to prevent the romantic pollution played a good role. However, the establishment of independent ventilation of the split-network structure, than the average non-independent ventilation of mixed-flow network (ie, the middle of the return air duct without return or air return airway network), the need to cut more and maintain a considerable amount of dedicated Return airway. Whether all the metallurgical mines need to establish an independent ventilated split-network structure? The use of non-independent ventilation of mixed-flow network of mines should be how to improve the network ventilation
