Numerical simulation on influencing factors of dust concentration in ore unloading station
Abstract
为了掌握卸矿站卸矿时卸矿量、巷道风速、矿石粒径和壁面条件对巷道内粉尘浓度的影响,以国内某矿山2号卸矿站为研究对象,运用ANSYS软件对该卸矿站建模、模拟,研究巷道粉尘浓度与卸矿量、巷道风速、矿石粒径和壁面条件之间的关系.研究表明,数值模拟结果与实测结果基本吻合;下风向巷道粉尘浓度大小与卸矿量成正比例关系,与风速、矿石粒径成反比例关系;满足生产条件的情况下,卸矿量5 000 kg/s、巷道风速1.5...
