我矿深部工程井下排水系统位于-430m中段,地下水C1浓度为866.18mg／L,水中CF浓度较高,腐蚀性较大。井下正常涌水量为10 000 m3/d,最大涌水量15 000m3／d。选用5台 D280-65／84×9型离心式水泵。水泵的技术参数为Q=280 m3／h,H=596.25m。配套电机型号Y450-4,功率800 kW,电压 6kV。正常情况下,3台泵工作,1 台检修,1 台备用。布置方式为单排布置,1 段排水。井下水从-430 m中段水仓用离心式水泵经主竖井内2条φ351×12排水管路直接排至地表+86m。
The deep underground drainage system of mine is located in the middle of -430m, the concentration of C1 in groundwater is 866.18mg / L, the concentration of CF in water is higher and the corrosion is bigger. The normal underground water inflow is 10 000 m3 / d and the maximum water inflow is 15 000 m3 / d. Choose 5 D280-65 / 84 × 9 centrifugal pumps. Pump technical parameters for the Q = 280 m3 / h, H = 596.25m. Matching motor model Y450-4, power 800 kW, voltage 6kV. Under normal circumstances, 3 pumps work, a maintenance, a standby. Arrangement for a single arrangement, a section of drainage. Downhole water from -430 m in the middle of the water tank with a centrifugal pump through the main shaft 2 φ351 × 12 drains directly to the surface +86 m.
