摘要:
矿山生产由浅部转入深部后，需对矿井通风系统进行整体的技术调试和优化工作。针对某地下开采矿山深部工程通风系统试运行效果不佳的问题，通过对通风系统现状调查和检测，分析得出通风系统风量不足，风路不畅，阻力大，主扇能力不够，存在漏风等问题，提出了查找封堵漏风点、并联回风线路降阻、主扇风机优化选型、辅扇风机平衡回风线路阻力等调试优化方案；采用Ventsim三维通风模拟软件进行建模与计算分析，验证了调试优化方案的可行性；工程应用显示可以满足矿山井下深部生产通风需求。

Abstract:
After a mine production transfers from the shallow part to the deep,the whole technical adjustment and optimization of the mine ventilation system are required.Given the poor effect of the ventilation system in an underground mine after its trial operation of the deep project,through investigation and detection of the current situation of the ventilation system,the paper figures out that there are the problems such as insufficient air volume,blocked air path,high resistance,insufficient capacity of the main fan,and the existence of air leakage,puts forward some debugging and optimization schemes,such as finding and sealing air leakage point,reducing the resistance of parallel return air circuit,optimizing type selection of the main fan,balancing return air circuit resistance of auxiliary fan.Modeling and calculation analysis are carried out using Ventsim software,verifying the feasibility of debugging scheme.The engineering application shows that it can meet the production demand of the deep underground mine ventilation.
