Drainage facilities with underway water intake in open pit mines

The methods, means and circuits of drainage of open pit mines are characterized. The package of measures aimed to prevent flow of surface and ground water in open pits, and to remove water from open pits beyond the excavation boundaries is described. The information on the power consumption by drainage facilities is given. It is emphasized that in many instances, the cost of dewatering in open pits is comparable with the cost of mineral and overburden haulage, and the minimum energy consumption by drainage facilities is ensured by pumping at the minimum ratio of the total pump head to the pump efficiency. It is found that the relationship between this ratio and delivery within the operational range of the head-capacity characteristic of a centrifugal pump has a gradually decreasing or extremal nature. For reducing energy spent for drainage in the warm season by 10–50%, it is proposed to perform underway water intake from the force main with the subsequent water spraying over pitwall. The accident-free operation conditions of the drainage circuits with the underway water intake are the use of motor drives with sufficient power reserve to increase the delivery and the presence of sufficient suction head at the pump inlet. Spraying of withdrawn water over benches and slopes heated by the sun allows intensification of air renewal and enables reduction of pit water discharge in water bodies and dust emission in atmosphere without overwetting of rocks in open pit mines.

Keywords: open pit mining, pit water, normal water inflow, drainage facility, drainage circuits, pipelines, motor drive, delivery, head, efficiency, suction head, power reserves, hydro-mechanical property, power consumption, operating regime, adjustment, energy efficiency, underway flow rate, spraying systems, air renewal.
