尾矿库安全注意事项
[ 2013-1-24 13:16:00 | By: 杨远锋 ]
 

 尾矿库与水库有相似之处,库内有水。因此关键问题是确保尾矿坝安全可靠,为此要注意下列事项:

    (1)尾矿库必须有防洪设施。尾矿库内不仅存放有尾矿浆带来的水,而且尾矿库汇水面积内的水都会以地表迳流的渠道进入尾矿库。在设计尾矿库时,应按设计规范计算洪水量。为了防止意外情况,由于洪水季节地表迳流水量大,则应修筑截流沟渠,把一部分地表迳流在上游截出库外。在一些老尾矿库,沿尾矿库的纵坡方向修建一些排水井,井井相连,并通过井下排水管或排水沟渠把多余的澄清水排往库外。尾矿堆到一定高度时则从尾矿坝端向上游顺次序封闭已经完成任务的排水井。在设计和施工这种排水设施时,应充分考虑排水管道系统承受堆积尾矿的压力,以防排水系统被压垮,以免造成整个排水系统报废。

    初期坝旁修筑防洪道,在尾矿库的中后部设主备用的浮动泵站。

    (2)保证子坝的稳定性。无论采用哪种筑坝方法,必须对堆筑子坝的尾矿的粒度组成按试验成果严加控制。生产实践证明,小于37微米的细粒级尾矿所占比例过高时,将会影响子坝的稳定性。

    (3)尾矿坝要有一定的安全高度。尾矿库在生产过程中,尾矿坝的高度要高出实际排放在库内的尾矿堆积面1-2米以上,这样才能保证尾矿坝的安全。如果尾矿堆积面的高度与尾矿坝的坝顶高度相差无几,这是危险因素,一场暴雨可能使尾矿溢出坝顶,尤其利用尾矿堆筑子坝阶段更要确保安全高度。

    (4)尾矿坝应该是透水坝。尾矿库中的水不断地经过坝体(坝墙)排走一部分,排水线以下的坝体均含水或被水润湿,通常称这一排水线为润湿曲线。润湿曲线愈低,坝愈稳定。如果润湿曲结已升高到最高一层子坝的坝顶,说明尾矿水已淹没到子坝的顶部,尾矿坝已是被水浸泡的砂堆,坝体随时可能崩塌。为了确保坝体的安全,尾矿浆的排放应从坝顶均匀地向库内上游方向排放,把尾矿水尽量往库内压,使坝的内坡离积存尾矿水的位置有相当的距离。尾矿库的纵坡长度通常为50-120米为宜,对小型尾矿库可相应变短,这段干坡(即表面无积水)的长度与润湿曲线的高度成反比。
