煤矿通风系统通风难易程度评价及应用

Evaluation and Application of Ventilation Difficulty Degree of Coal Mine Ventilation System

矿井通风系统会随着开采以及生产方式变化而调整,对矿井通风系统通风难易程度进行评价并优化矿井通风可在一定程度提升矿井通风效率。针对矿井新采区、老采区通风现状,提出综合采用通风阻力、等积孔方法对矿井通风难易程度进行评价,并依据测量结果对各路线风量分配进行优化,提高了矿井通风效果。

The mine ventilation system will be adjusted with the changes of mining and production mode. Evaluating the ventilation difficulty of the mine ventilation system and optimizing the mine ventilation can improve the mine ventilation efficiency to a certain extent.In view of the current situation of ventilation in new and old mining areas of the mine, it is proposed to comprehensively adopt the ventilation resistance and equal volume hole methods to evaluate the difficulty of mine ventilation, and optimize the air volume distribution of each route according to the measurement results, so as to improve the ventilation effect of the mine.
