根据高寒矿井穿脉巷道掘进的实际参数建立数值模型,分块划分计算网格,依据掘进进尺和风筒口距掘进工作面的距离,利用Fluent流体分析软件对不同工况条件下的炮烟扩散规律进行数值模拟.模拟结果表明:随着风筒口距掘进工作面的距离增加,CO排除的速度越慢;通风时间与穿脉长度和风筒口到掘进工作面的距离有一定的函数关系.
According to the actual parameters of tunneling through the alluvium mine, a numerical model is established and the grids are divided into blocks. According to the distance between the tunneling footage and the face of the tunnel, the Fluent fluid analysis software is used to analyze the rules of the spread of the smoke under different working conditions The simulation results show that the speed of CO removal is slower with the increase of the distance from the working face to the working face, and the ventilation time has a certain relationship with the length of perforating veins and the distance of the duct face to the heading face.
