Abstract: The proposed tailing reservoir is located at the Qianglanggou gully in the southwest of the Second Phase Development of the Jiala Copper Polymetallic Deposit in Huatailong Mine, Tibet. The tailing dam fill material is predominantly waste soil and rock from the mining operation. The additional borrow material should be directly from local site with a priority consideration of areas inside the reservoir. This paper presents the geotechnical test results on the tailing sands and other materials under construction conditions. The tested items are: Physical and mechanical properties of tailing sands, in-situ plate loading test and mold bag vibration compact tests. The results indicate that, the moisture content and density are significantly affecting the mechanical properties of the tailing sands; 

Key words: Tailing Sand for Dam Construction, Physical and Mechanical Properties, Bleeding, Permeability, Axial Static Loading Tests, Mold Bag Vibration Compaction Test
