上游法尾矿筑坝特性试验研究

Experimental Study of Tailing Disposal by Upstream Method

本文结合本钢南芬二期尾矿坝,进行了矩形活动水槽断面试验,研究了尾矿坝冲积滩形特点以及尾矿动水沉降特性,并结合原型实测资料给出了实用的尾矿堆筑坡度的计算公式及滩面尾砂颗粒分布.

With Nanfen tailing in Benxi, the sectional experiment is carried out in a rectangular mobile sluice. The characteristics of the depositing beach of tailing dam, and settling velocity of tailing in movable water are studied. Associated with the mesured prototype data a practical calculated formula of tailing depositing slope is thus obtained.
