Center line type tailing dam and damming method thereof
The invention relates to a midline type tailing dam and a damming method thereof.The midline type tailing dam comprises an initial dam and a silt arrester and is characterized in that a seepage drainage mattress is arranged at the dam bottom between the initial dam and the silt arrester and provided with a longitudinal horizontal perforated pipe; the transverse horizontal perforated pipe is communicated with one end of the longitudinal horizontal perforated pipe and located at the bottom of the tailing pond, the transverse horizontal perforated pipe is connected with the vertical seepage drainage well, a sand blocking sub-dam is arranged between the initial dam and the sand blocking dam, and a separation sub-dam is arranged on the initial dam. Rapid seepage drainage is facilitated, outer dam slope shaping and sand setting tailing consolidation are achieved, the problem that the outer dam slope of a fill dam is difficult to shape is solved, deformation of the fill dam body is conveniently controlled, and the effect of improving the anti-sliding performance and the anti-seismic performance of the tailing dam is obvious.
本发明涉及一种中线式尾矿坝及其筑坝方法，所述中线式尾矿坝，包括初期坝，拦砂坝，其特征在于初期坝与拦砂坝之间的坝底设有排渗褥垫，排渗褥垫上设有纵向水平穿孔管，以及与纵向水平穿孔管一端连通的位于尾矿库底部的横向水平穿孔管，横向水平穿孔管与竖直排渗井相连，初期坝与拦砂坝之间设有拦砂子堤，初期坝上设有分隔子坝。有利于快速排渗，实现外坝坡定型和沉砂尾矿固结，解决堆积坝外坝坡定型难的问题，方便控制堆积坝体变形，在提高尾矿坝的抗滑、抗震性能等方面效果明显。
