TO A QUESTION OF REALIZATION OF AN OFF-PEAK POWER CONSUMPTION ON MINE WATER OUTFLOW
Lately creation and exploitation of systems of automatic control (SAC) by mine water-removing installations is based on incessantly controlled water level in a catchment basin. Turning on and shutdown of the pumping units (PU) depends on the level of water. Electrode sensors of the lower, top and emergency levels are usually used for these purposes independently of electric part of SAC. A huge problem on mine water outflow is a creation of systems of automatic control, reliability of their functioning and the organization of a constant control of water capacity. The effective solution of this problem requires determination of dependences of the current water levels in a catchment basin of time of inflows, as during the water accumulation periods (at disconnected PU), so during the removal periods (at connected PU).The solution of a problem of improvement of mine water outflow is an application of SAC pumping units which are based on the mathematical equations. Also, for achievement of improvement of mine water outflow it is needed an existence of excess hydraulic capacities, including the pump equipment. The considered task in this article will lead to effective realization of an off-peak power consumption at the minimum capital and operational expenditure. However, the productive decision is possible only by full consideration of this task.
