关于风流稳定性必须考虑把进行评价时的风量稳定性和流向稳定性区別开来。对于构成通风不稳定的危险性,较之垂直或平行的风道一次或二次对角通风方面还大。一次对角通风时,关于风量和方向的单相风流的稳定化很大部分可以用影响风流通过的对角式通风连续起来改变矿井作业地点的阻力来达到。关于二次对角通风就不仅仅依靠与风流单流风道的阻力,而且也依靠由主扇产生的压力,所以稳定化是可以用风阻的变化或
Regarding the stability of the wind flow, it is necessary to consider distinguishing the stability of the wind flow from the stability of the flow during the evaluation. For the composition of the risk of instability ventilation, compared to vertical or parallel to the air duct once or twice diagonally larger ventilation. With a diagonal draft, the stabilization of the monophase flow in the wind and direction can largely be achieved by changing the resistance of the mine site with diagonal ventilation that affects the passage of the wind. About secondary diagonal ventilation depends not only on the resistance of the wind-induced single-flow duct, but also on the pressure generated by the main fan, so the stabilization can be done either with a change in wind resistance or
