Historical remaining tailing pond accumulated liquid guiding and discharging method
The invention discloses a historical remaining tailing pond accumulated liquid guiding and discharging method. The historical remaining tailing pond accumulated liquid guiding and discharging method comprises the following steps of firstly, downwards sinking a guiding and discharging well section by section according to an open caisson method, then welding the guiding and discharging well, conducting sand and broken stone filling, and then sealing the bottom of the guiding and discharging well; connecting a siphon pipe with the guiding and discharging well by using a drilling machine; and finally, leading part of water in a flood drainage ditch into the siphon pipe through a pipeline. According to the historical remaining tailing pond accumulated liquid guiding and discharging method, an infiltration line in a dam body of a tailing pond is effectively reduced, the stability and safety of the tailing dam are guaranteed, and the purpose of protecting the environment is achieved; and according to the method, only the water in the flood drainage ditch needs to be led into the siphon pipe to form a certain atmospheric pressure difference, guiding and discharging of the tailing well accumulated liquid are promoted, and the operation cost is low.
本发明公开了一种历史遗留尾矿库积液导排方法，所述历史遗留尾矿库积液导排方法是先将导排井按照沉井方法逐节向下沉放，再将导排井焊接、填充沙和碎石后封底；接着利用钻机将虹吸管与导排井相连；最后利用管道引入部分排洪沟中的水至虹吸管中；本发明历史遗留尾矿库积液到导排方法有效降低尾矿库坝体内的浸润线，保证尾矿坝的稳定安全，达到保护环境的目的；本发明方法仅需要将排洪沟中的水引入虹吸管中形成一定的大气压差，促进尾矿井积液的导排，运行费用较低。
