为减少尾矿的堆存量,使浓缩后的尾矿排到库外,近年来云锡已采用绞吸式挖泥船来完成这一工作,但尚未将其用于尾矿回采。随着生产的发展,尾矿开采利用变得日益需要。本文对绞吸式挖泥船的生产能力、采挖参数、特别是对移步距的控制,提出了见解,回采方法及其优点进行分析后,认为它可用在无落水洞的尾矿库中回采尾矿。文中对防止船体陷入落水洞等有关问题亦提出了建议. In order to reduce the stock of tailings and to concentrate the tailings discharged to the outside of the reservoir, in recent years, Yunxi has adopted a cutter suction dredger to complete this work, but it has not yet been used for tailings recovery. With the development of production, tailings mining and utilization has become increasingly needed. In this paper, the production capacity and the parameters of excavation, especially the control of the moving distance of the cutter suction dredger are put forward. After analyzing the opinions, the mining methods and their merits, it is considered that it can be used in the tailings reservoir without sinkhole Back to the tailings. The paper also put forward some suggestions on preventing the hull from falling into the water hole.
