摘要
自然风压是矿井通风的一种动力形式,但它是一把双刃剑,利用得当可以协助主通风机克服矿井通风阻力,利用不当则成为矿井通风的阻力,甚至引起井筒无风、微风或反风现象,酿成安全事故。通过对自然风压的成因研究,分析温度对矿井自然风压的影响程度,对井筒反风时的温度进行定量分析并提出针对性的措施和建议,以消除矿井通风系统安全隐患。
Natural air pressure is one of powers of the ventilation system in mines.However,it is a double-edged sword.In other words,if properly used,it could facilitate ventilators to overcome resistance in mines,otherwise,if improperly used,it would become the ventilation resistance,even cause zero,light,or inverted wind,which may lead to accidents.Factors of the natural air pressure are studied.The paper also analyzes the effect of temperature on the natural air pressure.Based on the quantitative analysis of temperature when inverted wind happens,appropriate measures are proposed to eliminate hidden security risks in the ventilation system in the mines.
