High-concentration tailing direct alluvial dam and damming method thereof
The invention provides a high-concentration tailing direct alluvial dam and a damming method thereof, the high-concentration tailing direct alluvial dam comprises an initial dam provided with a drainage ditch, a seepage drainage mattress arranged at the bottom of an upstream tailing pond of the initial dam, and an ore drawing pipe, and is characterized in that the top part of the initial dam extends to the upstream tailing side and is provided with a geotechnical reinforced grating; a drainage and seepage ditch net composed of a plurality of longitudinal drainage and seepage blind ditches and a plurality of transverse drainage and seepage blind ditches is arranged on the geotechnical reinforced grating, a plurality of sub-dams are sequentially arranged on the drainage and seepage ditch net and close to the initial dam, and the geotechnical reinforced grating is arranged on the upstream tailing side where the tops of 2-3 sub-dams extend. A seepage drainage ditch net composed of a plurality of longitudinal seepage drainage blind ditches and a plurality of transverse seepage drainage blind ditches is arranged on the geotechnical reinforced grating. Water in the tailings is removed as much as possible, consolidation of the tailings is effectively accelerated, stability of a dam body is improved, safety of a tailings pond is guaranteed, the tailings are used for damming, engineering investment is reduced, operation management is convenient, construction operation is simple, and energy conservation and consumption reduction are achieved.
本发明提供一种高浓度尾矿直接冲积坝及其筑坝方法，高浓度尾矿直接冲积坝，包括其上设排水沟的初期坝，设于初期坝上游尾矿库底部的排渗褥垫，以及放矿管，其特征在于初期坝顶部延伸至上游尾矿侧设有土工加筋格栅，该土工加筋格栅上设有由若干纵向排渗盲沟以及若干横向排渗盲沟构成的排渗沟网，在排渗沟网上且靠近初期坝依次设有若干子坝，间隔2‑3个子坝顶部延伸至的上游尾矿侧设有土工加筋格栅，该土工加筋格栅上设有由若干纵向排渗盲沟以及若干横向排渗盲沟构成的排渗沟网。尽量脱去尾矿中的水分，有效加快尾矿的固结，提高坝体稳定性，保障尾矿库安全，利用尾矿进行筑坝，降低工程投资，便于运行管理，施工操作简单，既节能又减耗。
