Tailing pond is one of the important facilities of mine production, which is used to stack the tailing waste discharged by the concentration plant. China’s mines produce more than 300 million tons of tailing every year, and the amount of tailing discharged is huge. Due to the limitation of land resources, tailing pond location will face more and more challenges. In this paper, the scheme of building tailing pond on the loose deposits is studied, and the influence of the load produced by the new tailing pond on the stability of the loose yards is analyzed. According to the analysis conclusion, tailing pond is built on the loose yards, and the accumulation of tailing is beneficial to the stability of the slope of the loose yards. However, if strict anti-seepage measures are not taken, the infiltration of pond water into the slope will reduce the stability of the slope, but in general, it is still greater than the safety factor of its own stability.
