摘要
北方冬春季节较为干燥,温度低,矿浆排出后表面形成冻结层,在风力作用下,表面尾矿颗粒易被扰动。在库区一定区域内产生扬尘。通过采取多点排放及尾矿粒度控制等措施,扬尘现象得到有效抑制。
In the winter,it is drier and the temperature is lower. As a result,there is a frozen crust on the surface of discharged ore pulp and tailing particles on the surface are easily to be disturbed with the wind action so that dust is raised in certain area of reservoir region. The problem is effectively solved through such measures as multi- point discharge and control of granularity for tailings.
