我矿选矿厂日处理200吨铅锌矿石,每日尾矿输送量800米~3,矿浆浓度25%左右,粒度50～55%-200目。输送方式:尾矿由浮选柱放出进入分配井后,利用地形高差,采用倒虹吸管自流至1号井,沿坡度i=0.04砖砌砼抹面明槽长1022米自流至尾矿坝。倒虹吸管(附图):全长214米,材质为内径90毫米,壁厚10毫米的铸铁管。考虑维修,共设2根,沟底设管柱支承。倒虹吸管尾矿进出口的高差13.6米,管线水平距离195米,在管的最低点处设事故放矿闸门。
I mine processing plant daily processing of 200 tons of lead-zinc ore, daily tailings delivery 800 meters ~ 3, pulp concentration of about 25%, particle size 50 ~ 55% -200 mesh. Transportation: Tailings released by the flotation column into the distribution well, the use of terrain elevation, using inverted siphon gravity flow to the No. 1 well, along the slope of i = 0.04 brickwork wipe surface 1022 meters long tidal flow self-flow to the tailings dam. Inverted siphon (with photos): a total length of 214 meters, the material is 90 mm in diameter, wall thickness of 10 mm cast iron pipe. Consider the maintenance, a total of 2, ditch pipe column support. Inverted siphon tailings import and export of the height difference of 13.6 meters, the pipeline horizontal distance of 195 meters, the lowest point in the tube set the accident release gate.
