METHOD OF USING WORKED-OUT UNDERGROUND MINE WORKINGS FOR STORAGE OF WASTE MUD FROM BRINE PURIFICATION PROCESSES

摘要

The method for underground depositing of sludge from brine-treatment plant. The method is distinctive in that sludge is introduced into a mine working alternately with loose and porous material, with the material layers (5 and 7) laid under and over the sludge layer (6), allowing for the fact that the thickness of the sludge layer (6) should not exceed 70% of that of the loose and porous material layers (5 and 7).IMAGE
