矿井通风系统阻力测定及控制分析

Analysis on resistance measurement and control of mine ventilation system

本文以野川煤矿通风系统运行情况为研究对象,选择使用精密气压计逐点测定法对该矿通风系统进行全面测定,分析得出该矿进风段、用风段及回风段的比例为:28.54∶34.46∶49,相对于科学比例有着较大的差距,该矿结合实际情况,采取了对应的优化控制策略,取得了较好的优化效果。

Based on ventilation system operation in Yeehuan Mine, precision barometric point - by - point method was adopted to measure the mine ventilating system, the proportion of inlet, outlet and return air sections was settled as 28.54 ： 34.46 ： 49, with a large difference to the reasonable proportion, the corresponding measures were given to get good effect.
