某钨矿井下通风系统方案优选

Scheme optimization of underground ventilation system in a tungsten mine

为解决某钨矿山井下深部通风问题,通过通风系统全面调查、测定和分析,得出矿井通风系统存在问题有:矿井总进风量不足、作业中段新鲜风量不足,且风流分配不均、通风网络与通风构筑物不够完善等问题。针对矿井目前存在的问题,提出并确定了最佳通风技术方案,有效解决矿井通风系统存在的问题,对深部矿山通风系统优化研究有着重要的借鉴意义。

in order to solve the deep ventilation problem in a tungsten mine,through the comprehensive investigation,measurement and analysis of the ventilation system,it is concluded that the existing problems of the mine ventilation system include:the total air intake of the mine is insufficient,the fresh air volume in the middle of the operation is insufficient,and the air flow distribution is uneven,and the ventilation network and ventilation structures are not perfect.In view of the existing problems in the mine,the optimal ventilation technology scheme is put forward and determined to effectively solve the problems in the mine ventilation system,which has important reference significance for the optimization of the ventilation system in deep mines.
