PREVENTION METHOD OF LIQUID CONTAMINATIONS FRONTAL ADVANCE IN FORMATION MASSIF

摘要

FIELD: mining engineering.;SUBSTANCE: invention relates to mineral resource industry and other field, where it is possible environmental pollution by liquid compounds, process waters or it is observed feeding of polluted water into mine openings. Method includes construction of hydraulic screen perpendicularly to flow of polluted water, creating in water-bearing bed by route of hydraulic screen shaft - by means of feeding into stratum of pure water and level lifting in it of subsurface water. By route of hydraulic screen it is constructed linear or circular loop system of injection wells, united by water-feeding pressure conduit. Water-feeding pressure conduit is connected to pump station and is outfitted by doing units of feeding into injected water of compounds contaminations neutralising, and also control system of pressure modes and productivity of water pumping-in.;EFFECT: invention expands range of application hydraulic screens and increases its maintainability.;1 dwg, 1 ex
