Abstract
FIELD: mining. SUBSTANCE: device for dewatering sedimentation includes water storage pond, filter, drain system, piping. Additional support is installed in the water storage pond in front of the main support. Exterior side of the additional support is covered with load bearing and maintaining girds. Layers of granular materials of different compositions are placed in the space between the supports. Provided with leaves filtering crossovers with apertures are placed in ends of the pond. Pond bottom is sloping from its center to both sides towards ends and covered with a layer of granular material. Drain pipes are placed in both inter-support space and bottom. Grain size of the first layer is 30 - 70 mm, the second layer is 10 - 20 mm, the third is 3 - 5 mm. EFFECT: high efficiency. 2 cl, 4 dwg
