众所周知,在矿井通风中,角联网路的存在给通风管理造成一定困难,特别是在具有煤层自然发火矿井中,当角联网路中的对角风路为采空区时,对角风路的漏风给采空区残煤的自然造成了供氧条件。然而,一旦发生自燃时,是否可以利用角联网路中风流的流动规律,控制对角风路的漏风量,使其 As we all know, in the mine ventilation, the existence of the corner network caused some difficulties in the ventilation management, especially in the spontaneous combustion of coal mines, when the diagonal network in the corner network for the goaf, the diagonal Leakage to the gob of natural coal caused by oxygen conditions. However, once spontaneous combustion occurs, whether the flow pattern of the wind flow in the corner network can be utilized or not, the amount of air leakage in the diagonal wind direction can be controlled
