Mukona was appointed to conduct liner intergrity and slope stability analyses using the PLAXIS 2D and PLAXIS 3D programs for a platform in Belfast Coal Mine, Mpumalanga

Client: Arup (Pty) Ltd

Key Collaborations: Exxaro Coal (Pty) Ltd

In order to assess the performance of a liner placed under engineered fill materials and imposed with foundation and stockpile loads, a geocomposite liner integrity analysis was carried out using the PLAXIS 2D program. The analysis provided the average tensile strength, strain and settlement of the geosynthetic material.

Key Facts: PLAXIS 2D and PLAXIS 3D analysis

PLAXIS 3D analyses were conducted for a stability assessment of a platform under static and cyclic loading from heavy dump trucks. The analyses provided factor of safety values, possible movement and stability of the proposed slope for different design scenarios.
