Use of washery tailings in hydrotechnical construction
Dam fill material must be sufficiently homogeneous to with-stand selective displacement. Tests were carried out on typical tailings, involving incremental sampling over periods of one hour, one shift, and one day for analysis. The results showed that the mineral content in the samples taken over 1 hour had the greatest qualitative and quantitative variability; those taken over a 24 hour period, the least. It was found that the tailings showed up well enough in situ, regardless of angle of wetting and internal friction angle. Tailings from Avdeev plant used in a dam and compacted by 4-6 heavy dump truck traverses in 1978. Inspection in 1979 failed to show any cracks or displacement, and filtration was found to be at a low level.
