本文以双角联风网为例,讨论矿井复杂风网中不稳定分支的风向判别、按需调节风量的方案选择以及火灾时期控制风流的急救措施,对加强矿井通风技术管理工作的预见性和矿井抗灾能力,提出了论点和方法。一、复杂风网中不稳定分支的风向判别矿井对角式的通风方式(见图1)往往形成双角联风网,其中1、3、6、8是经过采掘工作面的分支,3、6是风流方向不 In this paper, a case of double-angle combined wind network is taken as an example to discuss the wind direction discrimination of unstable branches in mine complex wind network, the selection of wind volume when needed and the first-aid measures to control the wind flow during the fire. Mine resilience, put forward the arguments and methods. First, the complex wind network unstable branch of the wind direction to identify mine diagonal ventilation (see Figure 1) tend to form a dual angle wind network, which 1,3,6,8 is through the mining face of the branch, 3, 6 is the romantic direction is not
