华丰煤矿通风阻力测定及分析

Measurement and Analysis of Ventilation Resistance in Huafeng Coal Mine

为了解矿井现有通风系统中各通风巷道风量和阻力分布,找出风量不足或过剩以及高风阻区段,对华丰矿井通风阻力进行测定,选用气压计基点测量法,得出华丰矿井通风阻力结果并分析。结果表明:用风、回风路段通风阻力占比大,存在较多拐弯,个别巷道严重变形;等积孔为4.1 m^(2),华丰煤矿为较为容易通风矿井。

In order to understand the distribution of air volume and resistance in various ventilation roadways in the existing ventilation system of the mine,identify sections with insufficient or excessive air volume and high air resistance,measure the ventilation resistance of Huafeng Mine,select the barometer base point measurement method,obtain and analyze the ventilation resistance results of Huafeng Mine.The results show that the ventilation resistance in the air using and return air sections accounts for a large proportion,there are many bends,and some roadways are severely deformed;The equivalent orifice is 4.1 m^(2),and Huafeng Coal Mine is a relatively easy to ventilate mine.
