The participation of renewable sources in the overall structure of energy resources is one of the key indications of progressiveness of an economy. In respect that the mining industry is the largest energy consumer in any country of the world, the authors analyze the application prospects and the parameters of energyefficient geotechnologies in integrated mineral mining. It is found that in the course of geotechnological transformation of the subsoil, it is possible to compensate mining-consumed energy by means of its reproduction. It is proved that the highest potential of energy reproduction belongs to the downward hydraulic mixture gravity flows that circulate all-year-round and are represented by contaminated drainage water with the increased content of solid as well as by cemented and hydraulic backfill mixtures manufactured from ore mining and processing waste. Advancement in the renewable power generation in mining is connected with the introduction of low-capacity hydroelectric installations (HEI) with the parameters governed by mining conditions, inflow of water to levels in surface and underground mines and by spacing of sublevels and levels of water bypass. The article shows that water handling flows are the year-round source for renewable energy production using mine facilities. The authors propose a circuit of cascade energy intake from slurry flows at intermediate levels and offer a mine flow intensity evaluation procedure that has been used to plot nomograms to determine generating capacity of HEI and to select low-capacity HEI based on the parameters of areas of operation of axial bulb and rotary HEI. With an intent to produce energy from slurry flows, layouts are designed for the current models of HEI equipped with the low-capacity power generators (to 100 kW) with blade, bucket and longitudinally rotating impellers, the related laboratory tests are carried out and the empirical relationships between the recovered energy and the slurry flows are plotted. The output, performance and operating conditions are evaluated for each turbine in the course of recovery of energy from slurry flows of diff erent viscosity, with the varied solid/liquid ratios, depending on the slurry flow head, infeed angle and the turbine location in a mine.
The studies are carried out under budgetary funding of IPKON RAS, Topic No. 0138-2014-0001.
