Outline
Through relevant calculation, the effectiveness of the design measures of a tailings pond was verified. Based on the GEO-SLOPE numerical simulation, the seepage and stability of the tailings pond under different working conditions were comprehensively evaluated. The results show that under the flood control standard of once in five hundred years, the discharge capacity of the flood interception ditch on east and west sides of the tailings pond and the discharge capacity of the spillway in the tailings pond area can meet the requirements. Through seepage calculation and analysis, the effectiveness of seepage control measures of tailings pond is verified. HDPE geomembrane and drainage system have good anti-seepage effect. Under the calculation of three working conditions, the anti-sliding stability of the downstream slope of the tailings pond can meet the design standards. The suggestion of arranging manual monitoring and on-line monitoring facilities is put forward to realize the real-time monitoring of dam of tailings pond and flood discharge situation. The research results can provide a technical reference for the design, construction and management of tailings pond.
