普鲁萨格(Preussag)金属公司研究了一种新的水力运输矿石技术,它将巷道内高浓度浆体水平运输技术与传统的低浓度浆体竖井垂直提升技术结合起来,在井下采掘工作面附近,将矿石粉碎,并调成高浓度浆体,水平泵送至竖井,在井下用高压泵将高浓度矿浆直接且连续地注入水流中稀释。稀释后的矿浆经竖井垂直管道输送到地表。矿石经过脱水后。送往选矿厂。
Preussag Metals has investigated a new hydraulic transport ore technology that combines the horizontal transport of high-concentration slurry in roadways with the vertical lift of conventional low-consistency slurry shafts to mine downhole workfaces Near the ore crushed and transferred to a high concentration of slurry, the level of pumping to the shaft, the high pressure pump downhole with a high concentration of pulp directly and continuously into the water flow dilution. The diluted slurry is delivered to the surface by the vertical pipe of the shaft. Ore after dehydration. Sent to the concentrator.
