摘要
在分析矿井通风系统存在问题的基础上,对矿井通风系统进行优化,并取得显著效果.矿井通风系统总进风量从原来的10369m^3/min增大至14893m^3/min,总通风阻力从1892.3Pa降低至1427Pa,改善了矿井通风系统,可以满足矿井生产通风的需要.
On the basis of analyzing the existing problems of mine ventilation system, the mine ventilation system is optimized and remarkable results are achieved. The total air intake of the mine ventilation system increased from 10369m^3/min to 1489m^3/min, and the total ventilation resistance decreased from 1892.3Pa to 1427Pa, which improved the mine ventilation system and met the needs of mine production ventilation.
