煤矿通风系统改造

Transformation of Coal Mine Ventilation System

随着开采范围不断扩大,深度逐渐增加,供风距离越来越长,通风阻力显著增加,风量不能满足二水平同时生产要求。通过通风状况分析和通风阻力测定,找出影响矿井通风的阻力段进行通风路线调整,同时采取减小矿井漏风等措施,提高了矿井有效风量。

With the mining rang constantly enlarging,the mining depth is constantly increasing,the ventilation resistance is obviously increasing and air amount can t meet the needs of production at same time at two level.By the analysis of the ventilation state and the inspection of the ventilation resistance,finds the resistance section effected mine ventilation to make the ventilation line adjustnent while adopting the measures of reducing mine air leakage,which increase the effective air quantity of mine.
