Substantiation of parameters of the energy-efficient water outflow scheme of underground mine using energy of hydro-flows

Abstract

The purpose of the study is development of a structural scheme of mining-engineering system designed to ensure energy performance of the mine water outflow system. The article reveals the need for research aimed at improving the energy efficiency of the water outflow system by comparing the dynamics of electrical energy consumption and commercial output volume at the mining industry enterprises. A brief overview of the global experience in compensation for growth of electric energy consumption under more difficult mining conditions and mining depth due to the use of innovative technological solutions in the mine water outflow system is given. Scientific novelty of the research is the use of energy, which is bypassed to the underlying horizons of the underground mine, of technological and natural waters to improve efficiency of pumping units by using boost pressure and automated processes of cleaning hydraulic flows from sludge deposits, as well as to reduce the overall operational costs in the water outflow system. The energy-efficient scheme of mine water outflow system that increases energy efficiency of a mining enterprise is substantiated.
