“…Yi & Du [8] found the strength of reinforced tailings increased substantially through triaxial compression tests on geogrid or geotextile-reinforced tailings; besides, pseudo-cohesion of shear strength index increased, whereas the friction angle remains primarily unchanged with the increase in reinforced layers. Ozhan & Guler [9] found that geomembrane-laminated geosynthetic clay liner had both perfect mechanical and hydraulic performance against sliding along the terraced slopes of a boric acid tailings dam. Palmeira et al [10] presented a study on the use of nonwoven geotextiles in drainage and filtration systems of tailings dams and found the overall performance of the geotextiles tested under laboratory conditions was satisfactory.…”

Tailings dam is a man-made hazard with high potential energy; dam failure would cause great losses to human lives and properties. However, the limitations of conventional reinforcement methods like geosynthetic make it easy to slide along the weak structural plane. In this paper, we innovatively added basalt fibre (BF) with different lengths ( l ) and contents ( ω ) into tailings to study its mechanical and permeation characteristics. The results indicate that BF can improve the shear strength ( τ ), cohesion ( c ) and compression index ( C c ) of tailings, but it has little effect on internal friction angle ( φ ). When l is constant, τ , c and C c are positively correlated with ω . One notable phenomenon is that τ and c do not constantly increase with l when ω is constant, but obtain the maximum under the optimal length of 6 mm. Moreover, when ω > 0.6%, permeability coefficient ( k ) is greater than that of the original tailings and the sensitivity of c , φ , τ , C c , k to fibre content is greater than that of length. The research results facilitate the understanding of BF reinforced tailings, and could serve as references for improving the safety of tailings dam and other artificial soil slopes or soil structures.

Waste dams (tailings) are used for storing the byproducts of mining operations and very common in mine industry. As the material they are storing can be harmful for the environment and the people in the vicinity, the construction of these dams is of high importance. During the construction phase, the topography of the site and geological-geotechnical parameters of the soils around the dam are as important as the stability and the leakage issues of the main dam body. In this paper, a nickel-ore waste dam located in Manisa-Gördes, Turkey is investigated in detail. At the downstream side of the dam, there was a slope instability at the right-hand side slopes due to improper loading on the top of these slopes. Whether this slope failure will affect the stability of main dam body or not is the main question of this study. Within these con nes, 3D nite element analyses that cover a large area, including the dam, upstream and downstream sides and the waste have been performed before and after the planned downstream slope rehabilitation. The results show that after the rehabilitation of the slopes, the deformations decreased considerably and the waste dam became safer.
