随着大型、特大型矿井数量的增多和老井开采范围的扩大,复杂通风网路日趋普遍。在较大矿井中,甚至在一个采区里,复杂通风网路也难以避免。众所周知,稳定和控制风流方向首先为煤矿安全所必须,因此,风流方向的研究,引起了越来越多的人的注意和兴趣。这一研究,不但为煤矿安全所重视,而且为完善和发展通风理论所必须。探索复杂通风网路风流方向的规律,将有可能使人们在理论上获得控制风流方向的新武器。近几年来,一些学者和专家陆续发表了关于通风网路风流方向的著作和论文,得出了许
With the large number of large and extra large mines and the expansion of the old mining area, the complex ventilation network is increasingly common. In larger mines, complex ventilation networks are difficult to avoid even in a mining area. It is well-known that the direction of wind flow and stability must be first and foremost necessary for the safety of coal mines. Therefore, the research on the direction of wind flow has attracted more and more people’s attention and interest. This research, not only for coal mine safety attention, but also for the improvement and development of ventilation theory necessary. Exploring the law of the direction of Merry Ventilation in a complex ventilation network will make it possible to theoretically obtain new weapons that will control the direction of Merry. In recent years, a number of scholars and experts have published books and dissertations on the direction of the ventilation network.
