Potential hazard treatment method for tailing dam in plateau alpine region
The invention discloses a hidden danger treatment method for a tailing dam in a plateau alpine region. The method comprises the following steps of (1) transferring tailings in a reservoir area back to the front of an initial dam through an automobile to artificially form a part of dry beach; (2) carrying out anti-seepage treatment on a hillside by adopting a geomembrane; (3) treating an initial dam east dam body water seepage point in a flow guide mode; (4) additionally arranging inverted filtering bodies at the contact parts between the two sides of a middle mountain body and a dam body; and (5) treating a landslide appearing in the middle mountain through slope cutting and ballasting. According to the method, a series of problems occurring in east and west dams and the mountain body between the east and west dams in the initial stage of a tailing pond are effectively solved by adopting the unique hidden danger treatment method for the tailing dam in the plateau alpine region, and hidden dangers are eliminated; and after treatment is completed, east and west dam bodies and the middle mountain body in the initial stage of the tailing pond keep a good stable state in the subsequent normal ore discharging work of a tailing pond of a dressing plant, and the expected treatment effect is achieved.
本发明公开了一种高原高寒地区尾矿坝隐患治理方法，（1）将库区内尾砂通过汽车倒运到初期坝前，人为形成一部分干滩；（2）采用土工膜对山坡进行防渗处理；（3）通过导流方式对初期坝东坝体渗水点进行处理；（4）中间山体两侧与坝体接触处加设反滤体；（5）对中间山体出现的滑坡采用削坡压载的方式进行处理。本发明通过采用独创的高原高寒地区尾矿坝隐患治理方法有效地解决了该尾矿库初期东西坝及东西坝中间山体出现的一系列问题，消除了隐患。治理完成后该尾矿库初期东西坝体及中间山体在后续选矿厂尾矿库正常排矿工作中保持良好稳定状态，达到了预期治理效果。
