摘要:
为优选高海拔矿山独头巷道通风降尘方法,研究粉尘颗粒扩散和分布规律,以云南迪庆普朗矿海拔3 700 m的一条独头巷道为研究对象,利用Fluent软件进行数值模拟研究。建立基于长压短抽、长抽短压和压入式通风方法的6种通风方案模型,对6种方案的风流场、粉尘颗粒分布情况以及呼吸面粉尘颗粒浓度进行分析和比较,并选择压风口与掘进面的距离和风筒中心点与地面的距离2个参数对压入式通风除尘系统的压入风筒位置进行优化。对最佳方案的粉尘颗粒质量浓度及粉尘运移规律进行分析,并与相同通风条件下的平原矿山独头巷道进行对比。研究结果表明:对于该高海拔矿山独头巷道,选择压入式通风方法,压入风筒布置在巷道正中央正上方位置,且压风口与掘进面的距离Z=1.3
