摘　　要：采用基点气压计法对某煤矿通风系统阻力进行了系统测定,掌握了矿井通风现状.对启用主要角联分支通风参数进行了测定,并对矿井利用主要角联分支降低矿井通风总阻力进行了系统分析和网络解算,得出角联分支的存在可有效降低矿井总风阻、改变矿井主要角联分支可有效降低矿井通风总阻力等结论.This paper adopts the basic point barometer method to measure ventilation system resistance in a coal mine and ventilation parameters of main diagonal branch,to get to know the mine ventilation condition. It also carries out the systems measuring and network calculation to mine ventilation total resistance reduction by converting mine's main diagonal branch in this coal mine. This paper concludes that the existing of diagonal branch can reduce the mine's total wind resistance effectively,and the changing of the mine's main diagonal branch can decrease total ventilation resistance effectively etc.
