| Type of test | Equipment | Sample size | Conditions | Purpose |
| Compression tests | Single lever soil consolidation instrument (Figure 3(a)) | Cylindrical, base area 50 cm2, height 2 cm | Double-sided drainage, vertical pressures of 12.5, 25, 50, 100, 200, 400, 800, and 1,600 kPa | Investigate the compression deformation patterns of tailings and understand the impact of composition and gradation on the compression behavior of tailings |
| Triaxial shear tests | Strain-controlled direct shear instrument (Figure 3(b)) | Cylindrical, base area 30 cm2, height 2 cm | Two drainage methods, consolidated drained (CD) and undrained (CU), effective confining pressures of 50, 100, 200, and 300 kPa | Explore the shear strength of tailings, considering particle size, gradation, and drainage conditions, and the behavior of tailings under different vertical pressures |
| Dynamic tests | Dynamic tests (Figure 3(c)). | Cylindrical, base area 12 cm2, height 80 mm | Consolidated-undrained cyclic triaxial tests, Kc set to 1.0 and 2.0, effective confining pressures set at 200, 400, and 600 kPa | Study the dynamic response of tailings under cyclic loading, including dynamic elastic modulus and damping ratio, and the dynamic shear stress value under a certain number of vibration cycles |
