日常管理中降低通风阻力的路径探析

将降低矿井通风阻力纳入矿井通风系统的日常管理当中,对矿井通风系统当下和长远发展更有益处。为探究日常管理中降低通风阻力的有效路径,首先论述了应改变简单草率的通风系统调整观念,在每次通风系统调整时,考虑选择能使通风阻力最小的最优方案;在分析了通风设施的作用后,发现在通风阻力最大路线上,不构筑通风设施,可以更大程度降低矿井通风阻力。加强富余风量、材料运输存储、主要通风机及其附属装置管理,降低主要通风机负压,都可以降低通风阻力,也更有利于主要通风机长期有效运行。

Discussion on the way of reducing ventilation resistance in daily management

It is more beneficial for the current and long-term development of mine ventilation system to bring the reduction of mine ventilation resistance into the daily management of mine ventilation system.In order to explore the effective way to reduce the ventilation resistance in daily management,we should first change the traditional ventilation system adjustment method,and consider the selection of the optimal scheme to minimize the ventilation resistance in each ventilation system adjustment.By analyzing the function of ventilation facilities,it is found that in the route with the maximum ventilation resistance,without building ventilation facilities,the ventilation resistance of the mine can be reduced to a greater extent.strengthening the management of the surplus air volume and the material storage,the main fans and their accessories,and reducing the negative pressure of the main fan can reduce the ventilation resistance,which is also more conducive to the long-term and effective operation of the main fan.
