摘要: 根據高寒礦井穿脈巷道掘進的實際參數建立數值模型,分塊劃分計算網格,依據掘進進尺和風筒口距掘進工作面的距離,利用Fluent流體分析軟件對不同工況條件下的炮煙擴散規律進行數值模擬.模擬結果表明:隨著風筒口距掘進工作面的距離增加,CO排除的速度越慢;通風時間與穿脈長度和風筒口到掘進工作面的距離有一定的函數關系.

Abstract: According to the actual parameter of across vein roadway tunneling in alpine mine, the numerical simulation was set up, and the computation grids were piecemeal-divided. Referring to the tunneling footage and the distance between venting duct and heading face, the diffusion law of blasting fume under different operating modes was simulated by the Fluent fluid analysis software. The simulation results show that the slower the preclusion speed of CO is, the longer the distance between venting duct and heading face, and the ventilation time has a certain functional relationship between the length of across vein roadway and the distance from venting duct to heading face.
