Method for solving local seepage drainage of upstream type tailing dam through vibration liquefaction
The invention relates to the technical field of civil engineering and mine engineering, and discloses a method for solving local seepage drainage of an upstream type tailing dam through vibration liquefaction, and the method comprises the following steps: step 1, determining an area with a relatively high seepage line according to tailing pond seepage line monitoring data; 2, slope drilling is conducted in the area, a seepage drainage pipe is arranged at the elevation angle of 5-7 degrees, the seepage drainage pipe is composed of a non-hole section, a hole opening section and a closed section, the non-hole section is located above the infiltration line, the hole opening section is located below the infiltration line, and the closed section is arranged at the tail end of the seepage drainage pipe; thirdly, a plurality of vibrators are installed in the perforated section of the seepage drainage pipe, the frequency of the vibrators ranges from 1000 Hz to 2500 Hz, the vibrators are arranged at intervals in the axis direction of the seepage drainage pipe, and the distance between the vibrators is not smaller than 3 m; fourthly, a plurality of drainage holes are formed in the top of the perforated section of the seepage drainage pipe. Through a vibration liquefaction technology, local fine-grain tailings are liquefied, pore water is rapidly discharged, the height of an infiltration line is reduced, and the local seepage drainage effect is improved.
本申请涉及土木工程及矿山工程技术领域，公开了一种利用振动液化解决上游式尾矿坝局部排渗的方法，包括以下步骤：步骤一、根据尾矿库浸润线监测数据，确定浸润线偏高的区域；步骤二、在所述区域内进行坡面钻探，排渗管以仰角5°～7°布设，排渗管由无孔段、开孔段和封闭段组成，无孔段位于浸润线以上，开孔段位于浸润线以下，封闭段设置在排渗管末端；步骤三、在所述排渗管的开孔段内部安装多个振动器，振动器的频率为1000～2500Hz，振动器沿排渗管轴线方向间隔布置，间距不小于3米；步骤四、所述排渗管的开孔段顶部设有多个排水孔。通过振动液化技术，使局部细粒尾矿液化，快速排出孔隙水，降低浸润线高度，改善了局部排渗效果。
