莱芜市金牛矿业开发公司金泉矿区由于生产的需要,一期工程中-6以上水平的矿石日渐萎缩,采矿要到-6以下水平。根据2003年6月招远工业设计院有限公司的设计,二期开采工程的水泵房安装位置选在-71水平,泵房内设安装100D-30×10型水泵4台,电机功率225 kW,水泵流量155m~3/h,扬程290 m。在实际应用中,由于矿井井下供电是低压供电,供电距离达600 m,金泉矿区现有10/ Laiwu Jinniu Mining Development Company Jinquan mining area due to the needs of production, a project -6 ore above the level of shrinking, mining to -6 below the level. According to the design of Zhaoyuan Industrial Design Institute Co., Ltd. in June 2003, the installation location of the pumping station in the second phase of mining project is selected to be -71 level. There are four 100D-30 × 10 type pumps installed in the pumping station, the motor power is 225 kW, Pump flow 155m ~ 3 / h, head 290m. In practical application, because the mine underground power supply is low voltage power supply, the power supply distance is up to 600 m, Jinquan mine existing 10 /
