Technology of power production from hydraulic fluid flows toward enhanced energy efficiency of gold mining

One of the key trends in development of theory and methodology for underground mine planning and design with a view to sustainable functioning of geotechnical systems in integrated mineral mining is enhancement of energy efficiency of production. It is of the current concern to develop and justify parameters of technology for power generation in underground mines from potential energy of process flows in a mine-technical system. Based on the promising designs and engineering solutions on conversion of energy of hydraulic fluid flows and the relevant recommendations on power generation during deep-level mining, the technology of power production from hydraulic fluid flows was tested. The tests demonstrated feasibility of using energy of hydraulic fluids as an extra source of power in underground mines and revealed the necessity of re-structuring of a mine-technical system with regard to power generation prospects. As a result, the guidance for recuperation of energy of hydraulic fluids was developed.
