A detailed study of the facility layout such as its operational processes, flow of materials and activity relationships has been done.
Multi-floor layout differs from single-floor layout in terms of travelling time, distance and vertical transporting of materials.
As can be observed in Figure 4, there are 38 cross-traffics on this floor, and this has resulted in a poorer movement of materials.

(a) The initial dam (b) The accumulative dam Fig. 1 Photos of the target tailings dam According to the tailings geotechnical study and the dam design information, material partition of the tailings was shown in Figure 2, and the mechanical parameters of materials were listed in Table 1.
As the initial dam was constructed with rock-fill materials, which means good permeability, and the spill point of saturation line at the bottom of the initial dam is helpful to the stability of the tailings dam

The effective factors such as materials modulus, the density as well as the assembling all contribute to the analyzed results.
Table 2 The relationship between basic frequency and material elastic modulus Material elastic modulus (GPa) 25 35 45 55 65 75 basic frequency（HZ） 1721 1744 1760 1782 1801 1816 Table 3 Relationship between basic frequency and materials density materials density（kg/m3） 1160 1360 1560 1760 1960 2160 basic frequency（HZ） 1774 1768 1760 1751 1743 1732 It is seen that the honeycomb panel’s basic frequency will decrease with the materials density increasing, and it will increase with the material elastic modulus increasing .So we can choose the right material according to the requirements of the task timely.
